Electrochemiluminescence (ECL) is a luminescence production technique triggered by electrochemistry, which has emerged as a powerful analytical technique in bioanalysis and clinical diagnosis. During ECL, charge transfer (CT) is an important process between electrochemical excitation and luminescent emission, and dramatically affects the efficiency of exciton generation, playing a pivotal role in the light-emitting properties of nanomaterials. Reticular framework materials with intramolecular/intermolecular interactions offer a promising platform for regulating CT pathways and enhancing luminescence efficiency. Deciphering the role of intramolecular/intermolecular CT processes in reticular framework materials allows for the targeted design and synthesis of emitters with precisely controlled CT properties. This sheds light on the microscopic mechanisms of electro-optical conversion in ECL, propelling advancements in their efficiency and breakthrough applications. This mini-review focuses on recent advancements in engineering CT within reticular frameworks to boost ECL efficiency. We summarized strategies including intra-reticular charge transfer, CT between the metal and ligands, and CT between guest molecules and frameworks within reticular frameworks, which holds promise for developing next-generation ECL devices with enhanced sensitivity and light emission.

Although previous studies have generally explored the important role played by customers' negative feedback in shaping employees' behaviour, these studies have only briefly discussed the one‐sided effects of such feedback on employees' cognition or emotions. In addition, previous studies have not discussed in depth whether customers' negative feedback has both positive and negative effects. Based on the theoretical background of the cognitive–affective processing system, we constructed a dual‐path model of the impact of customers' negative feedback on job crafting via both cognitive and affective paths and investigated the moderating effect of the error management climate in this context. A three‐stage survey design was used to examine these assumptions by referencing data collected from 382 frontline employees working in various tourism and hospitality companies. In line with our expectations, we found that customers' negative feedback can have a double‐edged sword effect via these two paths and that the error management climate moderates this dual‐path mechanism. We conclude this research by discussing the theoretical and practical implications of our findings. [ABSTRACT FROM AUTHOR]

The aim of this study was to conduct transcriptomic, proteomic, and metabolomic analysis to provide a comprehensive view of plant response to tetracycline stress. Pumpkin seeds were cultured for 7 days without or with tetracycline at 10 mg/L. Pumpkin roots showed excessive growth inhibition, but not yet strong growth restraining in cotyledons. Tetracycline affected the abundance of metabolites related to flavonoid biosynthesis and amino acid metabolism. Main changes of metabolites in flavonoid biosynthesis were consistent with mRNA changes. Amino acid changes are mainly mediated by proteins or mRNAs. To be specific, tetracycline treatment increased the levels of rutin, caffeate, cinnamaldehyde, 4-hydroxycinnamic acid, ferulic acid, naringenin, apigenin, luteolin, (−)-epigallocatechin, astragalin, L-serine, and glutathione and the transcript levels related to these compounds; and decreased the levels of indole pyruvate, indole acetaldehyde, L-arginine, S-adenosylhomocysteine, L-glutamine, and gamma-glutamylcysteine and the transcript levels related to these compounds. Tetracycline treatment also increased the levels of oxoglutaric acid, L-glutamic acid, gamma-aminobutyric acid, and gamma-glutamylalanine and enzymes involved in their production; and decreased the levels of L-isoleucine, L-valine, and L-leucine and enzymes involved in their production. We elucidated several biological processes (e.g. phenylpropanoid/flavonoid biosynthesis pathways, amino acid metabolic pathways) that were altered by tetracycline, and provided a multi-omic perspective on the mechanisms underlying the response to tetracycline stress in pumpkin roots. We provide a useful reference for the development of environmental quality management methods. [Display omitted] • Tetracycline inhibited pumpkin root growth but not leaf growth. • Tetracycline affected flavonoid biosynthesis and amino acid metabolism in metabolome. • Main changes of metabolites in flavonoid biosynthesis were consistent with mRNAs. • Main changes of amino acids were mediated by either proteins or mRNAs.

Strength and stiffness are the main characteristics of high-quality dough products. As one of the key components to endow those functions to noodles, formation of disulfide bonds in alkali-soluble glutenin (ASG) is very important. Interaction of ASG and co-crystalized wheat amylopectin with NaCl could prompt formation of disulfide bonds of ASG and its mechanism was deduced in the paper. The results showed that the disulfide bonds contents of ASG were increased significantly by interaction with co-crystalized wheat amylopectin. The co-crystalized wheat amylopectin with 2% NaCl for 24 h at 30 °C was distinguished by the M n distribution of 0.55–0.95 × 106 g/mol, more chains with 18∼24 glucose residues being grafted from chains of 4∼7 glucose residues during the eutectic process, presence of the weak resonance enhancement at 96.5 ppm, molecular aggregate diameter less than 120 μm, and only one of X-diffraction angles 2 θ at 20. 2 °. In the process of interaction, Q β , Q δ , Y γ , Y ε of ASG and C1, C6 of what amylopectin involved in the formation of disulfide bond, the contents of intermolecular β-sheet decreased and those of intra-molecular aggregation extended β-sheet and random coils increased. The peak melting temperature and melting enthalpy of the mixture decreased significantly after co-crystallized wheat amylopectin interacted with the ASG. Co-crystalized wheat amylopectin with NaCl can be used as a reinforcing agent of wheat flour. [Display omitted] • Co-crystalized wheat amylopectin with NaCl could enhance disulfide bond formation of ASG. • Chains with 18∼24 glucose residues in wheat amylopectin promote more disulfide bond formation of ASG. • Only one of X-diffraction angles 2 θ at 20.2 ° exists in wheat amylopectin to promote more disulfide bond formation of ASG. • Q β , Q δ , Y γ , Y ε of ASG and C1, C6 of what amylopectin involve in the disulfide bond formation of ASG. • Contents of extended β-sheet and random coils increase during disulfide bond formation.

Heat shock proteins (HSP) are a large family of peptide proteins that are widely found in cells. Studies have shown that the expression and function of HSPs in cells are very complex, and they can participate in cellular physiological and pathological processes through multiple pathways. Multiple heat shock proteins are associated with cancer cell growth, proliferation, metastasis, and resistance to anticancer drugs, and they play a key role in cancer development by ensuring the correct folding or degradation of proteins in cancer cells. As research hotspots, HSP90, HSP70 and HSP27 have been extensively studied in cancer so far. However, HSP20, also referred to as HSPB6, as a member of the small heat shock protein family, has been shown to play an important role in the cardiovascular system, but little research has been conducted on HSP20 in cancer. This review summarizes the current cellular functions of HSP20 in different cancer types, as well as its effects on cancer proliferation, progression, prognosis, and its other functions in cancer, to illustrate the close association between HSP20 and cancer. We show that, unlike most HSPs, HSP20 mainly plays an active anticancer role in cancer development, which is expected to provide new ideas and help for cancer diagnosis and treatment and research. • HSP20 is involved in cell proliferation, progression and apoptosis. • HSP20 can be used as a tumor marker and prognosis.

Conductive gels have received extensive attention in flexible electronics due to their diverse characteristics. The requirement for versatility and incompatibility of the conductive fillers with the hydrogel matrix remain a challenge for hydrogels. Herein, the cellulose nanofiber stabilized liquid metal droplets are utilized to initiate the polymerization and simultaneously serve as solid conductive fillers to construct the polyacrylamide/MXene/glycerol hydrogel with eligible stretchability (1000%) and high environmental adaptability (−25 to 80 °C) for multifunctional sensing. The hydrogel is utilized as a flexible electrode to construct the triboelectric nanogenerator for mechanical energy harvesting and conversion as well as self-powered sensing. Importantly, as a versatile sensor, it combines temperature sensing and deformation sensing with a wide range of stimulus responses and exceptional sensing performance. The flexible temperature and strain sensors are realized with superior thermosensitivity and strain sensitivity. In addition, the hydrogel exhibits favorable photothermal antibacterial ability. This work opens new avenues for the preparation of photothermal, conductive, stress and thermal sensitive hydrogels for multimodal sensors, sketching a promising future for them in flexible and wearable electronics.

[Display omitted] • Iron/carbon composites derived from solid waste were applied in PMS activation. • FeAC-950/PMS exhibited an excellent activity for BPA elimination. • SO 4 •− plays dominant role in BPA removal compared with electron-transfer process. • FeAC-950/PMS system shows good performance to oxidize various organic pollutants. Efficient and low-cost catalysts are important for contaminant remediation in peroxymonosulfate (PMS)-based advanced oxidation processes (AOPs). In this study, a solid waste, generated by the polyferric chloride coagulation of the phenol-saturated powder activated carbon from an industrial wastewater treatment plant, was used to prepare metal/carbon composites under different pyrolysis temperatures (650–950 °C). The catalyst pyrolyzed at 950 °C (FeAC-950) exhibited the highest reactive activity for PMS activation as demonstrated by a series of electrochemical techniques. Nearly complete BPA elimination can be achieved within 60 min by 0.1 g L–1 FeAC-950 and 0.5 mM PMS. The results of electron paramagnetic resonance (EPR), chemical quenching and open circuit potential (OCPT) experiments demonstrate a combined radical and non-radical oxidation mechanism in the FeAC-950/PMS process and BPA was removed dominantly through radical pathway. Various persistent organic pollutants can be efficiently eliminated in the FeAC-950/PMS system. In addition, the present system showed good tolerance to natural organic matter as well as some common anions such as chloride and nitrate. This study dedicated a simple method to prepare an efficient solid waste-based catalyst in environmental catalysis. The outcomes will not only provide a value-added reuse approach for waste management but also facilitate the FeAC-950 applications in wastewater remediation technologies. [ABSTRACT FROM AUTHOR]

Flexible and lightweight solar cells are promising for numerous emerging applications, and organometallic halide perovskites are particularly suitable for flexible solar cell applications. Transferring state of art high efficiency perovskite solar cells (PSCs) processing onto a flexible substrate, however, is challenging, requiring substantial redevelopment of materials compositions, device architectures, and processing conditions. In this work, highly flexible, robust, stable, and high efficiency PSCs based on mica substrate have been successfully developed, exhibiting a champion photovoltaic conversion efficiency (PCE) of 18.0%, retaining more than 91.7% of the original PCE after 5000 cycles of large deformation bending, and being relatively stable against humidity under elevated temperature. Key to such excellent performance is the inorganic and transparent mica substrate that is chemically inert and stable under high temperature, so that processing developed for glass-based high efficiency perovskite solar cells (PSCs) can be readily applied without modification. Furthermore, the layered mica substrate is highly flexible, and van der Waals epitaxial growth of transparent conducting ITO relaxes the mechanical constraint on the PSCs substantially, reducing the strain in the device even under large bending deformation. We believe inorganic flexible mica substrate can be used as a platform for high efficiency PSCs compatible to glass substrate, speeding up the development of flexible PSCs substantially.

Metal halide perovskites have attracted considerable attention for use in flexible resistive random access memory (RRAM), due to their good photoelectric regulation, high ON/OFF ratios, and low fabrication costs. Flexible conductive substrates play a crucial role in improving RRAM device performance. Herein, mica/silver nanowires welded with aluminum-doped zinc oxide (mica/AgNWs@AZO) substrates with high-temperature resistance, high flexibility, high conductivity, and good stability have been successfully fabricated. The average sheet resistance 3.5 Ω sq−1 of the conductive mica substrate is 68% lower than that of a commercial PET/ITO, and it remains stable below 13.1 Ω sq−1 under 200 °C. The maximum conductivity of the mica/AgNWs@AZO substrate can reach 58 S/m after 64 h of tensile stress bending at a radius of 20 mm. Perovskite CsPbBr 3 nanocrystal (NC) RRAM is constructed on the mica/AgNWs@AZO substrate. The ON/OFF ratio 103 of the device in light is 102 times higher than that in dark under 5000 bending cycles. Flexible perovskite RRAM is a promising candidate for next-generation-logic, adaptive, non-volatile memory devices.
