Adjusting the ratio of oxidation states in a CuO@Cu2O for the optimization of electrocatalytic CO2 conversion to ethylene.

Understanding the impact of surface copper valence states on the distribution of electrochemical carbon dioxide products is critical. Herein, CuO@Cu2O with a Cu2+/Cu+ interface was fabricated using wet chemical etching approach. The hollow shape offered a large region for gas adsorption, while the interfacial mixed chemical state of Cu2+/Cu+ with tunable control ratio raised the local density of CHO* and accelerated the carbon-carbon coupling reaction.

Cardiovascular protective effects of natural flavonoids on intestinal barrier injury.

Natural flavonoids may be utilized as an important therapy for cardiovascular diseases (CVDs) caused by intestinal barrier damage. More research is being conducted on the protective properties of natural flavonoids against intestinal barrier injury, although the underlying processes remain unknown. Thus, the purpose of this article is to present current research on natural flavonoids to reduce the incidence of CVDs by protecting intestinal barrier injury, with a particular emphasis on intestinal epithelial barrier integrity (inhibiting oxidative stress, regulating inflammatory cytokine expression, and increasing tight junction protein expression).

Nanopore Discriminates Watson-Crick and Hoogsteen Hydrogen Bonds in Multiple DNA Contexts.

Watson-Crick and Hoogsteen hydrogen bonds aid the formation of highly ordered structures in genomic DNA that dynamically govern genetic modes such as gene regulation and replication. Hence, measuring and distinguishing these two types of hydrogen bonds in different DNA contexts are essential for understanding DNA architectures. However, due to their transient nature and minimal structure differences at the sub-nanometer scale, differentiating Watson-Crick hydrogen bonds from Hoogsteen hydrogen bonds is difficult.

Layer-specific biomechanical and histological properties of normal and dissected human ascending aortas.

Recent studies have attempted to characterize the layer-specific mechanical and microstructural properties of the aortic tissues in either normal or pathological state to understand its structural-mechanical property relationships. However, layer-specific tissue mechanics and compositions of normal and dissected ascending aortas have not been thoroughly compared with a statistical conclusion obtained. Eighteen ascending aortic specimens were harvested from 13 patients with type A aortic dissection and 5 donors without aortic diseases, with each specimen further excised to obtain three tissue samples including an intact wall, an intima-media layer and an adventitia layer.

Adjustment of Molecular Sorption Equilibrium on Catalyst Surface for Boosting Catalysis.

ConspectusFor chemical reactions with complex pathways, it is extremely difficult to adjust the catalytic performance. The previous strategies on this issue mainly focused on modifying the fine structures of the catalysts, including optimization of the geometric/electronic structure of the metal nanoparticles (NPs), regulation of the chemical composition/morphology of the supports, and/or adjustment of the metal-support interactions to modulate the reaction kinetics on the catalyst surface. Although significant advances have been achieved, the catalytic performance is still unsatisfactory.

Impacts of Housing Costs on Health and Satisfaction With Life Circumstances: Evidence From Australia.

This paper examines the causal impacts of rising housing costs on individual health and satisfaction with life circumstances, using a fixed-effects instrumental variable approach and individual-level panel data from Australia. Relying on the historical patterns of immigrant settlement, we construct an instrumental variable that exploits exogenous variation in housing costs driven by foreign investments that flow differentially into localities. We find that rising housing costs-as measured by composite housing costs faced by homeowners and renters living in an area-have a significant positive impact on individuals' self-assessed physical health and a significant negative impact on satisfaction ratings, but no significant impact on self-assessed emotional health.

750 V Breakdown in GaN Buffer on 200 mm SOI Substrates Using Reverse-Stepped Superlattice Layers.

In this work, we demonstrated the epitaxial growth of a gallium nitride (GaN) buffer structure on 200 mm SOI (silicon-on-insulator) substrates. This epitaxial layer is grown using a reversed stepped superlattice buffer (RSSL), which is composed of two superlattice (SL) layers with different Al component ratios stacked in reverse order. The upper layer, with a higher Al component ratio, introduces tensile stress instead of accumulative compressive stress and reduces the in situ curvature of the wafer, thereby achieving a well-controlled wafer bow ≤ ±50 µm for a 3.
