Summary: The construction of S-scheme heterojunctions with efficient charge separation is a promising strategy for the development of high-performance photocatalysts. This study successfully synthesized oxygen vacancy-enriched WO3/BiOBr heterojunction nanoflowers and demonstrated their superior photocatalytic performance for the degradation of organic pollutants. The oxygen vacancies in the heterojunction provide accessible reaction sites and facilitate charge separation and transfer, resulting in enhanced photocatalytic activity and reduced aquatic toxicity of the pollutants.

Summary: A novel 1D/2D Bi2O2CO3-Bi2WO6 heterostructure with high photocatalytic activity was synthesized by high temperature calcination of Bi (OHC2O4)center dot 2H(2)O/Bi2WO6 precursors in CO2. The synergistic effects of the unique 1D/2D heterostructure and the high-quality interface between Bi2O2CO3 and Bi2WO6 contributed to the enhanced photocatalytic performance, where O-2(-) and photogenerated holes played key roles in the photodegradation process. This study offers a simple and general method for synthesizing 1D/2D heterostructures with excellent photocatalytic performance.

Summary: A Z-scheme heterojunction with all-solid-state structures was constructed, in which carbon dots acted as electron transferring mediators. The modified photocatalysts showed significantly higher activities, with ammonia production rates reaching above 232 lmol center dot gcal-1 center dot h-1 under light irradiation. The improved catalytic properties were attributed to the increased number of photoinduced oxygen vacancies, excellent visible-light adsorption abilities, and efficient photogenerated electron-hole separation efficiencies for the carbon dots bridged heterostructures. This study provides reasonable guidance for applications in photocatalytic ammonia synthesis and a promising construction strategy for efficient Z-scheme photocatalysts.

Summary: The study reveals that transition metal carbides and nitrides (MXenes) are inorganic compounds with two-dimensional structures. These substances are primarily composed of some atomic layers of transition metal carbides, nitrides, or carbonitrides. Ti3C2, the primary 2D-layered MXene, was first isolated in 2011. The conversion of mechanical, electrical, and electronic properties of MXenes highlights their exciting potential in energy storage, conversion, and utilization.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: This study investigates the effects of high energy/fluence proton radiation on the performance of HfZrOx-based FeFETs memory with different Zr content. The results show that the characteristics of FeFETs are influenced by proton radiation, and the extent of the influence depends on the Zr content. FeFETs with 50% Zr content exhibit minimal changes in memory window and demonstrate good endurance and retention performance.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
