Abstract

Water scarcity is a major challenge facing agricultural production in China. Unconventional water resources such as reclaimed wastewater can be used as a complimentary resource for irrigation. However, reclaimed wastewater is rich in salt and its long-term use for irrigation could lead to secondary soil salinization. In this review, we analyze the factors that have potential effects on accumulation of salt in soil. They include irrigation method, soil texture, crop types and crop variety, irrigation time, and reclaimed wastewater modification. Results show that our current understanding of the effect of long-term reclaimed water irrigation on soil salt accumulation is still unclear. As a result, more systematic studies are needed to elucidate the main factors that affect salt accumulation in soil. While reclaimed water modification is promising, more studies are required before it can be widely implemented. We suggest that future research on reclaimed water irrigation should focus on field experiments to systematically study how irrigation method, soil texture, crops, agronomic management and reclaimed water modification interactively affect salt accumulation in soils irrigated with reclaimed wastewater.

Abstract

Ti3C2Tx MXene/CuxO composites were prepared by acid etching combined with electrochemical technique. The abundant active sites on the surface of MXene greatly increase the loading of CuxO nanoparticles, and the synergistic effect between the different components of the composite can accelerate the oxidation reaction of glucose. The results indicate that at the working potential of 0.55 V (vs. Ag/AgCl), the glucose sensor based on Ti3C2Tx MXene/CuxO composite presents large linear concentration ranges from 1 µM to 4.655 mM (sensitivity of 361 µA mM−1 cm−2) and from 5.155 mM to 16.155 mM (sensitivity of 133 µA mM−1 cm−2). The limit of detection is 0.065 µM. In addition, the sensor effectively avoids the oxidative interference of common interfering species such as ascorbic acid, dopamine and uric acid. The sensor has good reproducibility, stability and acceptable recoveries for the detection of glucose in human sweat sample (97.5-103.3%) with RSD values less than 4%. Based on these excellent properties it has great potential for the detection of glucose in real samples. [ABSTRACT FROM AUTHOR]

46. Dual-Locked Probe with Activatable Sonoafterglow Luminescence for Precise Imaging of MET-Induced Liver Injury

Abstract

Metformin (MET) is currently the first-line treatment for type 2 diabetes mellitus (T2DM). However, overdose and long-term use of MET may induce a serious liver injury. What’s worse, diagnosis of MET-induced liver injury remains challenging in clinic. Although several probes have been reported for imaging MET-induced liver injury utilizing upregulated hepatic H2S as a biomarker, they are still at risk of nonspecific activation in complex physiological environments and rely on light excitation with limited imaging depth. Herein, we rationally designed and developed a dual-locked probe, DPA-H2S, for precise imaging of MET-induced liver injury by H2S-activated sonoafterglow luminescence. DPA-H2S is a small molecule consisting of a sonosensitizer protoporphyrin IX (PpIX) and an afterglow substrate that is dual-locked with a H2S-responsive 2,4-dinitrobenzene group and a 1O2-responsive electron-rich double bond. When employing DPA-H2S for imaging of MET-induced liver injury in vivo, since the PpIX moiety can produce 1O2in situat the liver site under focused ultrasound (US) irradiation, the two locks of DPA-H2S can be specifically activated by the highly upregulated H2S at the liver injury sites and the in situgenerated 1O2, respectively. Thus, the sonoafterglow signal of DPA-H2S is significantly turned on, enabling precise imaging of the MET-induced liver injury. In vitroresults showed that, through H2S-activated sonoafterglow luminescence, DPA-H2S was capable of imaging H2S with good sensitivity and high selectivity and realized deep tissue imaging (∼20 mm, signal-to-background ratio (SBR) = 3.4). Furthermore, we successfully applied DPA-H2S for precise in vivoimaging of MET-induced liver injury. We anticipate that our dual-locked probe, DPA-H2S, may serve as a promising tool in assisting the diagnosis of MET-induced liver injury in clinics and informing the clinical utilization of MET in the near future.

48. NIR‐II Ratiometric Fluorescent Nanoplatform for Real‐Time Monitoring and Evaluating Cancer Sonodynamic Therapy Efficacy.

Abstract

Real‐time monitoring the therapeutic process of sonodynamic therapy (SDT) is essential to optimize the treatment course in time and eventually improve the efficacy. The generation of singlet oxygen (1O2) is a quintessential characteristic of SDT, which permits non‐invasive monitoring of SDT by real‐time imaging of 1O2 inside the tumor. Nonetheless, the majority of probes are unable to measure 1O2 in real time because of its short half‐life and strong oxidative capacity. Here, the study constructs a ratiometric nanoplatform (DTPI) utilizing two fluorescent probes and the sonosensitizer TiO2. The poisonous 1O2 generated by DTPI following ultrasonic (US) radiation efficiently destroys tumor cells. The structural disruption of fluorescent dye IR‐1061 by 1O2 leads to a reduction in the DTPI fluorescence signal at 1100 nm, while US radiation has no impact on the fluorescence signal at 1550 nm. Thus, DTPI provides a precise and consistent reflection of the treatment efficacy at the tumor site, leveraging the ratiometric fluorescence signal and variations in oxygen content throughout the treatment process. This ratiometric‐fluorescence‐based reflection strategy establishes an effective and dependable platform for the real‐time monitoring and assessment of the cancer therapeutic effect through ratiometric probes.

50. α‑Fe2O3/Nb2O5/C Nanorods for Selective Photoelectrocatalytic Oxidation of 5‑Hydroxymethylfurfural under Solar Light.

Abstract

The epitaxial organization of nano-objects with different compositions and structures into superlattice nanorods holds great promise for photocatalytic biomass oxidation as it can make full use of sunlight and improve carrier transport efficiency. Here, we construct type II photocatalytic heterojunctions using α-Fe2O3 and Nb2O5, both of which are alternately grown in situ to form superlattice nanorod structures. Due to the interlaced growth of thin layers of α-Fe2O3 and Nb2O5, the phase interface between α-Fe2O3 and Nb2O5 is greatly increased, which effectively improves the catalytic activity of the catalyst. The selective oxidation of HMF was achieved by superlattice α-Fe2O3/Nb2O5/C nanorod photoelectrocatalysts with 96.6% FDCA selectivity, which was 2.3 times higher than that of α-Fe2O3 and 3.5 times higher than that of Nb2O5, respectively, and the conversion of HMF was close to 100%. This work provides a new idea for the design of catalysts with superlattice structure and used for biomass conversion. [ABSTRACT FROM AUTHOR]
