Summary: Graphene reinforced copper composites have potential applications in various industries, but the current preparation methods are complicated and expensive. This study successfully prepared graphene reinforced copper composites with excellent overall properties by combining electrodeposition, thermal reduction, and sintering. The addition of graphene improved the nucleation process and refined the grains, resulting in improved mechanical properties. The copper matrix was purified, and the oxygen-containing functional groups of graphene oxide were partially repaired, leading to improved electrical properties. Compared to the one-step electrodeposition method, the graphene in the composites had fewer oxygen-containing functional groups, ensuring thermal stability.

Summary: Electrocatalysis plays an important role in advanced clean energy production technologies. Traditional electrocatalysts made of noble metals suffer from disadvantages such as low abundance, low surface area, and high cost. Metal-organic frameworks (MOFs) have been explored as alternative electrocatalysts, but their insulating property and poor electrolyte stability limit their utility in desired technologies. New synthetic strategies have enabled the fabrication of electrocatalytically active MOFs for energy and environmental applications. This review discusses the synthetic approaches and recent progress of active MOFs in electrocatalytic applications such as oxygen reduction, oxygen/hydrogen evolution, and carbon dioxide reduction, with the aim of advancing MOF research in emergent technologies.

Summary: In this study, copper selenide nanoflakes were synthesized on copper foam and exhibited bifunctional catalytic activity for hydrogen evolution reaction (HER) and hydrazine oxidation reaction (HzOR). The high copper deficiencies in the Cu2-xSe phase contributed to faster electron transfers and the Cu2Se berzelianite phase played a role in long-term electrocatalytic stability. The catalysts showed potential for electrocatalytic hydrazine-assisted overall water splitting.

Summary: CuSe nanoparticles were synthesized via a microwave-assisted technique, and the role of irradiation time in regulating the size and shape of the nanoparticles was investigated. Characterization techniques were used to elucidate structural and optical properties. The optical band gap of the nanoparticles decreased with an increase in irradiation time, which was attributed to the increase in crystallite size.

Summary: A double-peak precipitation hardening is observed in a Cu-0.75Fe-0.35Ti alloy aged at 500 degrees C, with an early hardness peak appearing after 1 h aging and a second peak after 6 h aging. Transmission electron microscopy observation shows that abundant coherent precipitates with large lattice mismatch form in the 1 h-aged specimen, leading to strong coherency strengthening and the early hardness peak. With aging time increasing to 6 h, the precipitates transform into incoherent Fe2Ti/FeTi precipitates, strengthening the alloy through the Orowan bypass mechanism and causing the second hardness peak. The 1 h-aged specimen exhibits higher hardness (181.2 HV) than the 6 h-aged one (174.8 HV), while both have comparable electrical conductivity (56.8%IACS and 59.8%IACS, respectively). Our findings suggest the possibility of designing high-performance Cu-Fe-Ti alloy with coherent precipitates through a rapid process.

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: 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.

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.

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.
