Summary: In this study, a novel and facile one-step solid-state method for the preparation of gamma-Fe2O3 nanoparticles (NPs) was developed. The addition of aromatic acids to Fe(NO3)(3)•9H(2)O led to the formation of gamma-Fe2O3 NPs and significantly influenced their morphology. The gamma-Fe2O3 NPs obtained from the trimesic acid/Fe(NO3)(3)•9H(2)O system exhibited a porous three-dimensional hierarchical structure and the largest Brunauer-Emmett-Teller surface area.

Summary: Si@PVDF composite microspheres with Si nanopowder uniformly distributed were prepared by electrostatic spraying method. The improved interfacial contact quality in Si@PVDF led to enhanced chemical reactivity, as evidenced by reduced reaction onset temperature, peak temperature, and apparent activation energy compared to physically mixed Si/PVDF counterpart. Si/PVDF could not be ignited by Joule heating, while self-sustained combustion propagation was observed for Si@PVDF pellets. The combustion process of Si@PVDF pellets was influenced by equivalence ratio, pellet porosity, and O2 accessibility in the environment.

Summary: The review summarizes the progress in magnetic NTE materials from Invar alloys to newly discovered materials like Mn-based antiperovskites, Laves phases, La(Fe, Si)13, Mn3Ge, R2Fe17, R(Fe,V)12, and R2Fe14B (R = rare earth elements). The NTE properties of magnetic materials can be controlled by adjusting magnetic exchange interaction through methods like chemical substitution, nanocrystallization, external field, and interstitial atoms. The main mechanisms of NTE of magnetic materials, including order-to-disorder transition, change of local moment, metamagnetic transition, short-range magnetic ordering, structural phase transition, and coexistence of magnetic phases, are summarized.

Summary: This article demonstrates the significance of the origin of iron stearate precursors in the synthesis of iron oxide nanoparticles. Commercial grade and washed precursors result in triangular or cubic nanoparticles formation, while spherical nanoparticles are obtained from the laboratory-synthesized precursors. The presence of impurities, such as sodium stearate and/or sodium chloride, in the commercial precursors affects the reproducibility and growth of iron oxide nanoparticles. This finding has a major impact on the development and understanding of nanoparticle growth mechanisms.

Summary: Metal oxides (MOs) have significant importance in catalysts, sensors, capacitors, and water treatment. The unique properties of nano-sized MOs, such as surface effect, small size effect, and quantum size effect, have attracted much attention. Hematite, an important combustion catalyst, can greatly accelerate the thermal decomposition process of energetic materials (EMs) and enhance the combustion performance of propellants. This review summarizes the catalytic effect of hematite with different morphologies on EMs, as well as the methods for enhancing the catalytic effect using hematite-based materials and their effects on EMs. The provided information is helpful for the design, preparation, and application of catalysts for EMs.

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.

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.
