Poly（methyl methacrylate-b-styrene）（PMMA-b-PS） block copolymers are synthesized by two consecutive ATRPs and fractionated into four fractions. The halogen chain end fidelity （CEF） in PMMA-b-PS is quantified based on the analysis of each fraction. Compared to ethyl 2-phenyl-2-bromoacetate/CuBr/2,2＇-bipyridine （EPBA/CuBr/bpy） and CuBr/N,N,N＇,N＂,N＂-pentamethyldiethylene- triamine （CuBr/PMDETA） catalysts, PMMA-b-PS synthesized using p-toluenesulfonyl chloride/CuCl/bpy （TsC1/CuC1/bpy） and CuC1/PMDETA catalysts has a higher halogen CEF and a better control on molecular weight.

Metal clusters or even single-atoms dispersed and anchored on the photocatalysts'surface can enhance photocatalytic performances on organic pollutant ***,a simple photoreduction method was used to create atomically dispersed metal single-atoms/clusters(MSCs,M=Cu,Pd,Au and Ag)on P-modulated tubular carbon nitride(TCN).The obtained MSCs@TCN demonstrated excellent photocatalytic performances for the degradation of sulfamethazine(SMZ).In particular,the photocatalyst with 2 wt%Cu loading showed ultrahigh SMZ oxidation efficiency(k=0.06110 min^(-1)),almost three times that of TCN(k=0.02066 min^(-1)).It also shows excellent stability in the 5th-cycle *** improved photocatalytic activity of the CuSCs@TCN is ascribed to the synergistic promotion of photogenerated charge separation by Cu single-atoms/clusters as active sites,accelerated charge transfer from bulk TCN to Cu sites through Cu-N_(x)***,the active sites of Cu single-atoms/clusters could promote the production of·O_(2)^(-),which participates in organic oxidation with strong oxidizing holes(h^(+)).This strategy paves a new avenue for designing high-performance photocatalysts decorated with metal single-atoms and clusters.

AIM To elucidate the potential role of autophagy and the protective effects of Jiang Zhi Granule(JZG) in metabolic stress-induced hepatocyte *** An in vitro and in vivo approach was used in this study. Hep G2 cells were incubated in culture medium containing palmitate(PA; 0, 0.1, 0.2, 0.3, 0.4 or 0.5 mmol/L) and treated with or without JZG(100 μg/m L) for 24 h or 48 h, and the progression of autophagy was visualized by stable fluorescence-expressing cell lines LC3 and p62. Western blot analyses were performed to examine the expression of LC3-Ⅱ/LC3-Ⅰ, p62, m TOR and PI3 K, while mitochondrial integrity and oxidative stress were observed by fluorescence staining of JC-1 and reactive oxygen species. C57 BL/6 mice were divided into three groups: control group(n = 10), high fat(HF) group(n = 13) and JZG group(n = 13); and, histological staining was carried out to detect inflammation and lipid content in the *** The cell trauma induced by PA was aggravated in a dose-and time-dependent manner, and hepatic function was improved by JZG. PA had dual effects on autophagy by activating autophagy induction and blocking autophagic flux. The PI3 K-AKT-m TOR signaling pathway and the fusion of isolated hepatic autophagosomes and lysosomes were critically involved in this process. JZG activated autophagy progression by either induction of autophagosomes or co-localization of autophagosomes and lysosomes as well as degradation of autolysosomes to protect against PA-induced hepatocyte injury, and protected mitochondrial integrity against oxidative stress in PA-induced mitochondrial dysfunction. In addition, JZG ameliorated lipid droplets and inflammation induced by HF diet in vivo, leading to improved metabolic disorder and associated liver injury in a mouse model of non-alcoholic fatty liver disease(NAFLD).CONCLUSION Metabolic stress-induced hepatocyte injury exhibited dual effects on autophagy and JZG activated the entire process, resulting in beneficial effects

The thermoelectric performances of 1 T-ZrX_2(X=S and Se) single layers were investigated using a combination of density functional calculations and semi-classical Boltzmann transport theory. Because of the high hole mobilities at 300 K, ultrahigh power factors(PF = S^2σ) were found in the P-type compounds;these values were ~ 11.95 and ~13.58 mWK ~2 m^1 for 1T-ZrS_2 and 1T-ZrSe_2 single layers, ***, because of the Lorenz relation between the electrical conductivity(σ) and an electron's thermal conductivity(K_(el)) given by the Wiedemann-Franz law, the electronic figures of merit(Z_(el)T = PF T/K_(el)) at 300 K were approximately 0.67 and 0.75 for the N-and P-type 1T-ZrSe_2, respectively. In addition, the lattice thermal conductivities(K_(Ph)) were calculated, giving values of ~1.43 and ~0.97 W K ~1 m^1 for 1T-ZrS_2 and 1T-ZrSe_2 single layers, respectively. Therefore, because of the lower K_(Ph)/K_(el) ratio, the P-type 1T-ZrX_2 single layers possess higher fngure-of-merits(ZT = Z_(el)T/(1+(K_(Ph)/K_(el))) than their counterparts. This signifies that the P-type samples demonstrate better thermoelectric performance than the N-type ones. The thermoelectric properties of metastable 2H-ZrX_2(X = S and Se) single layers were also investigated.
