Summary: This work investigates the hydrogenation of CO2 to methanol over Cu/ZnO-based catalyst by focusing on the mechanism and interface effects. Atomic doping of Cu/ZnO-X(Al,Mg,Ga,Pt,Pd,Au) catalyst was simulated to study the enhancing effect of metal promoters. Density functional theory (DFT) calculation was conducted to analyze the adsorption, thermodynamics, and kinetics of CO2 methanolization. The simulation results provide guidance for the design of high-efficiency catalysis for CO2 hydrogenation and are consistent with previous experimental results.

Summary: A series of Cu-Zn catalysts encapsulated by Zr-based metal-organic frameworks (UiO-66) were prepared and investigated for CO2 hydrogenation to methanol. The Cu-Zn@UiO-66 catalyst with 35 wt% loading and Cu/Zn mole ratio of 2.5 exhibited the best catalytic activity and good reaction stability. The excellent performance was attributed to the ultrasmall nanoparticles and abundant Cu/ZnOx interfaces in UiO-66, as well as the strong interaction between Cu and ZnO, which promoted CO2 conversion and methanol synthesis.

Summary: By using reaction kinetics, TPR/TPD, N2O titration experiments, and in situ spectra techniques, this study reveals the mechanism of Mn promoter in regulating the catalytic activity and surface properties of Cu/ZnO/Al2O3 catalysts. The addition of Mn does not affect the methanol synthesis pathways, as confirmed by the unchanged methanol formation EA of Cu/ZnO/Al2O3 catalyst. However, an increase in Mn content leads to smaller sizes of Cu and ZnO, higher reduction degree of ZnO to Zn0, and more Cu-ZnOx active sites and surface species, resulting in higher methanol formation activity in CAZ-2%Mn.

Summary: Despite the ongoing debate on the nature of Cu-ZnOx synergy and the active Zn-based promoter species in methanol synthesis, this study uses weakly interacting graphitic carbon supports to investigate the active speciation of Zn promoter phase in contact with Cu nanoparticles under working conditions. The results reveal that most of the added Zn is in a zerovalent oxidation state during methanol synthesis conditions, and the Zn diffuses into the Cu nanoparticles. This study provides insights into the speciation of relevant Zn promoter species and highlights the importance of using weakly interacting graphitic supports for studying the nature of promoter species.

Summary: The catalytic hydrogenation of CO2 to methanol can be improved by doping tungsten into CeO2, resulting in a Cu/CeW0.25Ox catalyst with enhanced activity and selectivity. Experimental investigation reveals that this promotion effect is attributed to the reduction of Ce4+ to Ce3+ by W-doping, the suppression of oxygen vacancy formation on CeO2, and the activation of the formate pathway for CO2 hydrogenation. This catalyst design strategy differs from conventional CeO2-supported catalysts.

Summary: In this study, commercial Cu/ZnO/Al2O3 catalyst was confined in mesoporous SiO2-Al2O3 shell via hydrothermal synthesis for selective hydrogenation of CO2 to dimethyl ether (DME) and methanol. The active Cu-0-ZnO interface in CZAS@SA was preserved due to the confinement effect of the shell, which improved methanol selectivity and increased the total selectivity of DME and methanol from 9.1% to 63.3%.

Summary: Researchers synthesized Zn1-xSixO nanoparticles with tunable work function and carrier concentration by a thermal plasma method. They found that electrically conductive ZSO nanoparticles with a low work function promoted the hydrogenation of CO to methanol, while insulating ZSO nanoparticles with a similar low work function did not. This suggests that efficient electronic promotion plays a key role in low-temperature methanol synthesis.

Summary: Research has shown that optimizing the microstructure and surface properties of mesostructured Cu-ZnO/Al2O3-ZrO2 (CZAZ) catalysts, especially by adjusting the weight ratio of Al2O3 and ZrO2, can improve the catalytic performance of CO2 hydrogenation to methanol. The addition of ZrO2 enhances the catalyst's basic surface, while smaller Cu particles increase the interfaces of Cu with ZnO, thereby improving the selectivity to methanol.

Summary: In this study, Cu/ZnO/Al2O3 catalysts were modified by doping with MgO promoter through co-precipitation and impregnation methods. The modified catalyst (P-CZAM-R) showed small size and high dispersion of Cu particles, which effectively inhibited their growth during the reduction process. The catalyst also exhibited strong H2 adsorption capacity, facilitating the hydrogenation of CO2. As a result, the P-CZAM-R catalyst achieved a CO2 conversion of 10%, methanol selectivity of 80%, and demonstrated high stability under the conditions of 190 degrees C, 3 MPa, and a gas hourly space velocity of 10000 mL & BULL;gcat - 1 & BULL;h- 1.

Summary: This paper investigates the wave surface effect in a wireless optical communication system operating at an air-water interface. A Monte Carlo numerical method is used to develop and simulate an optical model of the system, and the impact of the wave surface, link distance, water turbidity, and receiver parameters on the communication link power is evaluated. The results demonstrate that turbidity and transmission depth can help reduce the fluctuation effect caused by wind-induced power loss. An experiment conducted confirms the reliability of the simulation results.

Summary: In this study, shafted microgears were manufactured using a microforming process. A grain-based modeling approach was used to simulate the forming process and investigate the effects of grain size on forming behavior and process performance. Five deformation zones with different hardness and stress-strain distributions were identified in the microstructures. The undesirable geometries of microgears, such as material unfilling, burr, and inclination, were observed and the inclination size increased with grain size. By redesigning the punch and adding a die insert, the forming quality of the microgears was improved.

Summary: In this study, 47 full-length HbTPS genes were identified in the Hevea brasiliensis genome, and they were divided into five subfamilies based on phylogenetic analysis. HbTPSs were found to participate in cellular components, molecular functions, and biological processes, as well as seven secondary metabolite pathways. They may be regulated by phytohormones, as suggested by the presence of cis-acting elements. RNA-Seq analysis revealed tissue-specific expression patterns of different HbTPSs. These findings contribute to understanding the role and molecular mechanism of HbTPSs and the regulation of terpenoid biosynthesis in H.brasiliensis.

Summary: This study applied a dielectric barrier discharge plasma to modify the performance of Pt/CeO2 catalyst for toluene oxidation. Different plasma discharge times were used and it was found that discharge time significantly affected the catalytic activity of Pt/CeO2 catalyst. The Pt/CeO2-PT3 (30 min) and Pt/CeO2-PT6 (3 h) catalysts showed improved catalytic activity, while the Pt/CeO2-PT5 (2 h) catalyst exhibited decreased activity due to surface carbon deposition.

Summary: Dilated cardiomyopathy (DCM) is characterized by left ventricular dilatation and contractile dysfunction, and its molecular mechanisms are not fully understood. This study examined the transcriptome and proteome of healthy and DCM myocardial tissue, identifying dysregulated processes such as extracellular matrix, mitochondrial function, and muscle contraction. Furthermore, a 4-biomarker panel (CTSB, vWF, C9, and MFGE8) was developed for the diagnosis of DCM.
