Summary: Magnesium rechargeable batteries are a promising option for large-scale energy storage. Many redox-active polymers have been reported to have good cycling stability in magnesium electrolytes, however, their magnesium storage capacity is lower compared to their lithium counterparts. This study introduces a novel sulfur-linked porous polymer with high material utilization and large pore volume, leading to improved reversible capacity in magnesium electrolytes. The research also identifies a strong correlation between the degree of electrochemical swelling of polymers and their specific capacity in both electrolytes. This work provides important insights for the design of polymer structures for multivalent ion-based energy storage.

Summary: Thermally oxidized activated carbon (TOAC), acidified activated carbon (AAC), and thermally deoxygenized AC (TAC) were prepared. TOAC showed the highest oxygen content and specific surface area among the three types of activated carbon. TOAC exhibited a significantly higher capacitance than AC, AAC, and TAC, indicating the synergistic effect of anchoring oxygen and large specific surface area on capacitance performance. The oxygen content enhanced the wettability between electrode and electrolyte, while the large specific surface area facilitated ions adsorption and ionic diffusion and transport.

Summary: This paper discusses the optimization of electrical and thermoelectrical properties of nanostructured polysilicon material for use in thermoelectric devices. The nanostructured porous polysilicon (POpSi) thin film is shown to significantly reduce thermal conductivity while maintaining Seebeck coefficient, resulting in a substantial improvement in ZT compared to standard polySi layers. The integration of POpSi into planar TE microgenerators leads to a 28% increase in simulated conversion efficiency compared to those using standard polySi layers.

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.
