We use a facile high-temperature solid-phase method to coat a layer of Ni-rich ternary material (LiNi 0.8 Co 0.1 Mn 0.1 O 2) on the surface of lithium iron phosphate. This active coating greatly improves the intrinsic conductivity of LiFePO 4. Compared to the conventional carbon material cladding, since this cladding layer is electrochemically active, the problem of decreasing the proportion of active material due to the addition of a cladding layer can be avoided to a certain extent. Compared with the samples capped with conventional organic carbon source (151.2 mAh g−1) and inorganic carbon source (155.9 mAh g−1) at 0.2 C, the discharge specific capacity was as high as 165.7 mAh g−1. Capacity retention after 200 cycles is up to 98 %, which is much higher than that of glucose and graphene oxide (GO)-coated samples (95.9 %, 96.6 %). Even when charging and discharging cycles are performed at different multipliers (2C and 10C), the retention rate remains higher than the latter. [ABSTRACT FROM AUTHOR]

Objective. To systematically evaluate the efficacy and safety of Huangqin Tang (HQT) combined with mesalazine for the treatment of ulcerative colitis (UC). Methods. The China Knowledge Network, Wanfang Data, VIP, PubMed, SinoMed, Embase, and Cochrane Library databases were searched for randomized controlled trials (RCTs) of UC with HQT in Chinese and English. The search time was from the establishment of the database to October 2021. The included literature was evaluated for data extraction and risk of bias, efficacy and safety were evaluated using the RevMan5.3 software, and the quality of evidence was evaluated using GRADE. Results. Six studies with a total of 565 subjects were included, and a meta-analysis showed that HQT combined with mesalazine for UC significantly improved the cure rate (RR = 1.56, 95% CI [1.23, 1.98), P = 0.0003) and overall efficacy rate (RR = 1.24, 95% CI [1.14, 1.35], P = 0.00001), which significantly reduced the clinical symptom scores; however, all had high heterogeneity. HQT combined with mesalazine modulated the patients' serum IL-6, IL-10, IgA, and IgG levels. HQT combined with mesalazine for UC tended to reduce adverse effects; however, the difference was not statistically significant. All GRADE ratings of the quality of evidence were of low quality. Conclusions. HQT combined with mesalazine in the treatment of UC significantly improved the cure rate and overall treatment efficiency and regulated the expression levels of serum IL-6, IL-10, IgA, and IgG.

We successfully prepare LiFePO 4 nanosheets with a primary particle linearity of only 50–80 nm with the {010} facet as the main exposed surface by using the mixed-solvent method, and control their agglomeration morphology by using ethylene glycol, diethylene glycol, and triethylene glycol (EG, DEG, and TEG) as the inducing agents, which solves the problem of the irregular agglomeration of the nanoparticles to a large extent. The obtained secondary particles have regular morphology, consistent particle size, staggered stacking between nanosheets, and the resulting stacked pores greatly increase the active sites of the material. In addition, due to the different molecular structures of the inducer of LiFePO 4 chelating degree of deviation, as a way to achieve the purpose of controlling the thickness of the carbon layer on the surface of LiFePO 4. The discharge specific capacity of the spiny spherical secondary particles prepared with EG can reach 168.5 mAh g−1 at 0.2 C, which is close to its theoretical capacity. Due to the nano effect of primary particles, the material is in full contact with the electrolyte and exhibits successively 149.8, 125.9 and 114.5 mAh g−1 even at high multiplicities (2 C, 5 C, 10 C). • The linearity of the primary particles of the prepared material is only 50-80 nm. • Primary particles prepared with the (010) surface as the main exposed surface. • Control of nanoparticle agglomeration morphology by inducers. • The LFP@EG exhibited high specific capacitance and good cycling stability.

It has always been an important research direction for improving the intrinsic conductivity of Lithium iron phosphate materials. Doping can not only improve the intrinsic conductivity but also induce lattice distortion to increase the diffusion rate of lithium ions to improve the electrochemical performance. Zn-doped LiFe 1-x Zn x PO 4 (x = 0, 0.025, 0.05, 0.075) is prepared from LiOH·H 2 O, FeSO 4 ·7H 2 O, H 3 PO 4 , ZnSO 4 ·7H 2 O. The composition, structure, morphology and electrochemical performance of the material are characterized in detail by XRD, SEM, EDS, cyclic voltammetry test, AC impedance test and other methods. The results show that the nano-spherical LiFe 0.075 Zn 0.025 PO 4 exhibits excellent capacity performance and rate performance without intentionally coating C. The initial discharge specific capacity of the positive electrode material is 153.6 mAh·g−1 at 0.2C. The material also exhibits excellent cycle performance, with a discharge-specific capacity of 148.6mAh g−1 and a capacity retention rate of 96.7% after 100 cycles at a current density of 0.2C. Compared with the undoped samples, the doped ZnSO 4 improves the actual capacitance of the samples. The high specific capacity retention rate at large rate charge-discharge indicates that zinc doping improves the structural stability of the samples. The crystal structure is not significantly damaged during the large current charge discharge process, and the magnification performance is improved. • Select zinc, the last element of the fourth period transition group, and make full use of its characteristics of small ionic radius and high charge density between ions. Make some bond energy strengthening, further stabilize the frame, improve the material cycle stability. • By one-step hydrothermal method, zinc salt with excellent water solubility is selected for doping, so that the raw materials can be mixed at atomic level, and the problem of uneven doping is solved. • Through the synergistic effect of adding CTAB and doping elements, the agglomeration and uneven particle size of nanoparticles are greatly improved. • The selected method is simple, the experimental repeatability is high, and the raw materials are easy to obtain.

Based on the chelation of 6-phenyl-4′-(4-[4-(diphenylamino)styryl]phenyl)-2,2′-bipyridine ( L ) to Hg(II) ions, two luminescent coordination complexes HgBr 2 L ( 1 ) and HgI 2 L ( 2 ) were prepared. Compared with the free ligand, the complexes exhibit enhanced two-photon excited fluorescence and larger two-photon absorption cross-section values. Time-dependent density functional theory calculations were carried to investigate the influence of central metal ion on the characteristic of charge transition of the complexes. The results indicated that the complexation of the ligand with Hg(II) ion causes stronger intramolecular charge transfer, leading to enhanced two-photon absorption of the complexes.

[Display omitted] • Pregnant women were widely exposed to NEOs and 6-CN was the most abundant metabolite. • IMI and ACE were adversely associated with neonatal head circumference. • Maternal 8-OHdG mediated the association between NEOs and neonatal head circumference. An increasing number of studies have reported neonicotinoid insecticides (NEOs), the emerging alternatives to conventional insecticides, may increase oxidative stress and cause adverse health effects, but limited is known about the prenatal NEOs exposures and their impact on birth outcomes. We investigated the levels of prenatal exposure to NEOs/metabolites, to assess their associations with birth outcomes, and investigate whether these associations could be mediated by oxidative stress using 8-OHdG as the biomarker. We studied 296 mother-infant pairs recruited from Laizhou Wan Birth Cohort in 2010 – 2013. Two NEOs (IMI and ACE), three metabolites (6-CN, ND-ACE, and 2CTCA), and 8-OHdG were measured in maternal urine collected before delivery. Birth outcomes including birth weight, birth length, ponderal index (PI), head circumference, and gestational age, were acquired. We examined the associations between NEOs/metabolites and birth outcomes using multivariable linear regression. Mediation analysis was conducted to clarify the role of 8-OHdG on the association of NEOs/metabolites exposure and birth outcomes. Highest detection rate was observed for ACE (100.0%), followed by IMI (98.3%) and 6-CN (98.0%), suggesting the common exposure of pregnant women. The highest median concentration was observed for 6-CN with creatinine-adjusted median levels of 9.58 μg/g creatinine. A decrease in newborns' head circumference was observed with a 10-fold increase in IMI (β = -1.83; 95% CI = -3.04, −0.62) and ACE (β = -2.27; 95% CI = -3.56, −0.98). An increase in newborns' PI was observed with a 10-fold increase in IMI (β = 0.40; 95% CI = 0.03, 0.75). Maternal 8-OHdG demonstrated 38.5–65.5% mediating effects in the negative association of IMI, ACE, 2-CTCA with head circumference. These associations might differ between boys and girls. Pregnant women were widely exposed to NEOs/metabolites in China. Results suggested the potential impacts of prenatal exposure to certain neonicotinoid insecticides on head circumference. Urinary 8-OHdG may partly mediate these associations. [ABSTRACT FROM AUTHOR]

Abstract: Superhydrophobic surface has been successfully prepared on cotton substrates with inexpensive and ordinary raw materials, Al(NO3)3 and sodium stearate (C17H35COONa). Such surfaces were obtained first by dip-coating the nano-Al sol, then the surface of the Al coating was modified with sodium stearate, to gain a thin film through self-assembly. The wettability of treated fabrics was characterized by water contact angle, spray test and hydrostatic pressure test. The results showed that the cotton fabrics treated with 1.5% Al sol and 20mmol/L sodium stearate showed excellent hydrophobic properties and UV protection efficiency, water contact angle could reach 146.27° and the UPF value was 164.06 (UPF rating 50+). The morphology and surface roughness were characterized by SEM and AFM. The interaction between sodium stearate and Al coating was elucidated by XPS. [Copyright &y& Elsevier]

This study aimed to compare the differences between oral administration and intravenous injection of polygalacturonic acid (PGA) in the regulation of immune and intestinal microflora in ulcerative colitis (UC) mice. PGA was administered orally or intravenously. PGA in the high-dose ig group was the most effective in treating UC by increasing colon length and downregulating disease activity index, histopathological score and proinflammatory cytokine levels. In spleen, the efficacy of PGA on restoring Th17/Treg balance in the high-dose iv group was better than that in the high-dose ig group, the opposite was observed in the lamina propria. The level of colonic IL-17A in the high-dose ig group was lower than that in the high-dose iv group, the opposite was observed for that of colonic IL-10. Western blot and immunohistochemistry analysis revealed that PGA in the high-dose ig group decreased the protein expression of RORγt, and increased that of FOXP3. Furthermore, PGA in the high-dose ig group was more effective than that in the high-dose iv group in improving the intestinal microflora structure. Our results suggest that in immune regulation, oral PGA is more effective in the lamina propria and gut microbiota while intravenous PGA is more effective in the spleen. [ABSTRACT FROM AUTHOR]

The Ni-Co-Zn alloy coating is prepared in a deep eutectic solvent system using pulse power supply technology, and the feasibility of the deep eutectic solvent system as an electrolyte is confirmed through infrared spectroscopy and cyclic voltammetry. The microscopic morphology analysis shows that the plating layer is uniform and dense, and the grains are spherical particles, and it is detected that the oxidized weight gain rate of the plating layer is 7.6842 × 10−8 g2 cm−4·h−1 at 900 °C, which is 3 orders of magnitude different from the oxidation rate constant of the substrate. The corrosion potential increases to −0.281 V in 3.5 % NaCl solution, and the corrosion current density decreases to 3.259 × 10−7 (A/cm2), with an ASR of 43.64 mΩ cm2 at 800 °C. The results indicate that the Ni-Co-Zn coating can meet the requirements for an SOFC connector material. • The Ni-Co Zn coating is prepared by low eutectic solvent system. • The results show that higher current density leads to hydrogen evolution. • The corrosion resistance of the coating is better than that of the substrate. • The oxidation resistance of the coating is better than that of the substrate.

This paper presents a novel ultra low jitter phase‐locked loop (PLL) circuit architecture for RF Sampling Transceiver. The programmable frequency divider with duty cycle expansion and the new phase frequency detector and charge pump circuit are used to solve the problem of voltage domain conversion of narrow pulses in the traditional high‐performance charge pump PLL structure. The traditional structure degrades charge pump linearity and noise, thus deteriorating overall jitter performance. Furthermore, voltage‐controlled oscillator uses the dual core structure and the second harmonic suppression technology, combined with the proposed new switching capacitor structure, and achieves −139.3 dBc/Hz phase noise at the 1 MHz frequency offset of the 5.2 GHz carrier under the open loop state. The PLL implemented in a standard Taiwan Semiconductor Manufacturing Company 28 nm process occupies a core area of 0.4 mm2 and generates a frequency ranging from 4 to 5.2 GHz using 50 MHz oscillator input, the power consumption is 40 mW. It achieves 74.8 fs root‐mean‐square jitter integrated from 10 KHz to 30 MHz. When the PLL output is divided by 2, the output phase noise at 1 MHz frequency offset is −125.75 dBc/Hz, and the PLL FoM is −246. [ABSTRACT FROM AUTHOR]

[Display omitted] • Prenatal PM 2.5 composition exposure was estimated in China with severe pollution. • Infant cognitive and motor functions in five domains were tested at 12 months by ASQ. • The effects of composition-specific PM 2.5 were further evaluated. • PM 2.5 compositions were negatively associated with ASQ scores in all five domains. • All PM 2.5 compositions except OM were associated with lower problem-solving scores. Prenatal fine particulate matter (PM 2.5) exposure has been linked to infant cognitive and motor functions, but the effects of PM 2.5 chemical composition remain unclear. We aimed to explore the associations of prenatal PM 2.5 and its composition exposure with infant cognitive and motor functions. We studied 2,435 mother-infant pairs in the Shanghai Birth Cohort Study. PM 2.5 and its seven compositions [primary particles (black carbon, mineral dust and sea salts) and secondary particles (NH 4 +, NO 3 –, SO 4 2- and organic matter)] during the three trimesters of pregnancy were retrieved from the V4.CH.03 product developed by using a combined geoscience-statistical method. At the 12-month-old follow-up, infant cognitive and motor functions in five domains were assessed using the Ages and Stages Questionnaire (ASQ). We used multivariable linear regressions to estimate the effects of PM 2.5 and its composition on the ASQ scores, for all infants and stratifying by sex and breastfeeding duration. PM 2.5 exposure was negatively associated with gross motor, problem-solving and personal-social scores for all infants. PM 2.5 compositions were inversely associated with ASQ scores in all five domains, and the effects of different compositions varied across domains. Specifically, all compositions except organic matter were correlated with lower problem-solving scores [e.g., (β S O 4 2 - = − 10.79, 95 % CI: −17.40, −4.18) ∼ (β N O 3 - = − 4.68, 95 % CI: −7.84, −1.53); for each 10 μg/m3 increase in PM 2.5 compositions during the third trimester]. Primary and some secondary particles (organic matter, NO 3 –) were related to lower gross motor scores. Secondary particles were also inversely associated with communication (organic matter and NO 3 –), fine motor (NH 4 +, NO 3 –, SO 4 2-) and personal-social (NH 4 +) scores. Additionally, boys and infants breastfed for < 6 months appeared to be more susceptible. We found negative associations of PM 2.5 and its compositions with infant cognitive and motor functions over a range of domains, especially the problem-solving domain. [ABSTRACT FROM AUTHOR]

Few studies have examined the adverse birth sizes of preconception exposure to organophosphate pesticides (OPs) in women undergoing in vitro fertilization (IVF). We investigated the relationship of preconception OP exposure with birth sizes among Chinese women undergoing IVF. This study included 302 couples seeking infertility treatment in the China National Birth Cohort Study, from Shanghai, China, who gave birth to singleton infants between 2018 and 2021. Clinical data were collected from medical records. We measured the concentrations of six nonspecific dialkyl phosphates (DAP) metabolites of OPs [diethylthiophosphate (DETP), diethylphosphate (DEP), diethyldithiophosphate (DEDTP), dimethyldithiophosphate (DMTP), dimethylphosphate (DMP), and dimethyldithiophosphate (DMDTP)] in maternal urine. DMDTP and DEDTP were precluded from further analyses due to the low detection rates. Generalized linear models (GLMs) and weighted quantile sum (WQS) regression analyses were performed to examine the individual and joint effects of OP exposures on gestational age, birth weight, body length, and ponderal index. Odder ratio (OR) of preterm birth were estimated using logistic regression models. Women in the highest as compared with lowest quartile of DEP had shorter gestational age (β = - 0.68; 95% CI = −1.24, −0.11). The association was modified by sex, with boys showing larger decreases in gestational age (β = - 0.86; 95% CI = −1.60, −0.13). No associations were found between other DAP metabolites and birth sizes. Results from linear models with individual DAP metabolites were corroborated by the WQS regression where DEP had the largest contribution to the overall mixture effect on gestational age (weight = 0.70). Moreover, DEP concentration was associated with an elevated risk of preterm birth (OR = 1.35, 95% CI = 1.11, 2.25). Preconception DEP concentration was associated with shortened gestational age and increased risk of preterm birth, and the association was more pronounced among boys than girls.

Per- and polyfluoroalkyl substances (PFAS) are believed to impair early neurodevelopment and disrupt thyroid hormone (TH) levels. However, there are limited epidemiological data on the neurodevelopmental effects in infancy of prenatal PFAS exposure and the potential mediating effects of TH. To evaluate potential associations between prenatal PFAS exposure and early neurodevelopmental deficiencies, and assess mediator effects of TH. From 2010 to 2013, 274 mother-infant pairs were recruited to the Laizhou Wan Birth Cohort in China. Ten PFAS and five TH were measured in cord serum. Developmental quotient (DQ) from 5 domains (adaptive, social, language, gross and fine motor) was assessed using Gesell Developmental Schedules for each child at 1 year of age. The associations between PFAS and DQs were evaluated using multivariable linear regressions. TH-mediated effects of PFAS on DQs were calculated by mediation analyses. Among our study population, PFAS exposures were common and associated with DQ decrement in infants. For each 10-fold increase in PFBS concentrations, gross motor and adaptive DQ decreased by 8.56 (95%CI: −15.15, −1.97) and 5.87 (95%CI: −8.07, −3.67) points, respectively. TSH mediated 12.90% of the association of PFBS with gross motor DQ and FT4 explained 19.63% of the association of PFBS with adaptive DQ. The negative association was also found between PFHxS exposure and gross motor DQ (β = 8.14, 95%CI: −15.39, −0.98). PFBS and PFHxS were negatively associated with early neurodevelopment, especially consistent in gross motor domain. The associations were partly explained by TSH and FT4. • The relationship between PFAS exposure, thyroid hormones and infant neurodevelopment were assessed in a Chinese birth cohort. • Prenatal PFHxS and PFBS exposure were associated with lower gross motor DQ, especially in males. • TSH and FT4 partly mediated the association of PFBS with DQ in several neurodevelopmental domains at 1 year of life.

Perfluoroalkyl substances (PFASs) are persistent and bio-accumulative compounds that have been recognized as important immune hazards by animal studies. However, epidemiological studies regarding the impact on infant infections were inconsistent. We investigated the associations between prenatal exposure to PFASs and acute infectious diseases including common cold, bronchitis/pneumonia, and diarrhea in early childhood. Participating 235 mother–infant pairs were recruited from the Laizhou Wan (Bay) birth cohort (LWBC), a prospective study in Shandong, China between September 2010 and 2013. Ten selected PFASs congeners including PFOA, PFOS, PFNA, PFDA, PFUA, PFDoA, PFHxS, PFBS, PFHpA, and PFOSA were measured from maternal serum by HPLC-MS/MS. Detailed information on parent-reported frequency of acute infectious diseases was collected from questionnaires at 1-year follow-up, which was confirmed by the medical records. Logistic and Poisson regression models were used on binary health outcomes (yes/no) and the number of episodes of outcomes, which were reported as odds ratio (OR) and incidence rate-ratio (IRR), respectively. The risk of diarrhea increased by 4.99 (95% CI = 1.86, 13.39) per log-unit increase in PFOA. The frequencies of diarrhea increased by 97%–116% for each 10-fold increase in PFOA, PFNA, and PFDA. Moreover, when stratified by exclusively breastfeeding duration (at least 4 months or not), the adverse effects of PFASs exposures on diarrhea were more pronounced among the breastfed infants. There were no associations between prenatal PFASs exposure and common cold or bronchitis/pneumonia. Exposure to PFASs was associated with increased risks of diarrhea during the first year of life, and these effects were stronger among the breastfed infants. Due to the small sample size, our results should be interpreted with caution and additional studies on larger populations are needed to confirm our findings. [Display omitted] • Perfluoroalkyl substances (PFASs) are widely used in China and around the world. • We assessed the association between PFASs and acute infectious diseases in infancy. • PFASs especially PFOA was positively associated with the occurrence of diarrhea. • The adverse effects were stronger among the exclusively breastfed infants.

Yellow color from vertically integrated light emitting device (LED) was reported. The multilayer structured Er and Eu doped Ga 2 O 3 films were deposited on sapphire and GaAs substrates by alternate-target pulsed laser deposition. The structure, surface morphology, and optical properties of the films were systematically investigated. Bright yellow electroluminescence originated from the combined simultaneous emission of excited Er3+ (529, 550 nm) and Eu3+ (615 nm) can be observed with the naked eyes at a low driven voltage of 10 V. Parameters of the yellow emission for the chromaticity diagram were calculated to be x = 0.4379, y = 0.5343. It is determined that the optically active Er and Eu ions are simultaneously activated by defect-assisted carrier recombination excitation. We believe that this work will provide a prospect for realizing low-voltage driven color LED using rare earth doped Ga 2 O 3 films. • Vertically integrated yellow LED based on Ga 2 O 3 :(Er + Eu) film was fabricated. • Yellow light can be observed with the naked eyes at a low driven voltage of 10 V. • Parameter of yellow light in chromaticity diagram was calculated as (0.4379, 0.5343). • The electroluminescence and transport mechanism were understood.
