Summary: This study demonstrates the anisotropic self-assembly of magnetic nanoparticles through the control of nanoparticle-protein interaction and magnetic force. The concentration of protein plays a crucial role in the interaction between nanoparticles and proteins and subsequent colloidal assembly. Different protein compositions also lead to variations in the morphology of the assembled structures. Furthermore, the assembled structures can be rapidly dissociated by adding a negative electrolyte, but the dissociated structures can still be recycled.

Summary: We conducted extensive computer simulations to investigate the hysteresis characteristics of ordered arrays of magnetic nanoparticles, and found that anisotropy and dipolar interaction have explicit effects on the hysteresis response. The system exhibits superparamagnetic behavior with weak dipolar interaction, resulting in minimal hysteresis loop area. Remarkably, double-loop hysteresis emerges even with moderate interaction strength, resembling antiferromagnetic coupling. These findings have important implications for applications such as digital data storage and spintronics.

Summary: Amorphous Fe3O4/SiO2 composite particles were synthesized using a one-pot sol-gel route. The evolution of Fe3O4 nanoparticles from the amorphous matrix on annealing temperatures up to 600 degrees C was studied. The analysis of magnetization data showed that annealed samples exhibited higher magnetization values and coercivity, suggesting short range magnetic order. The size and interparticle interactions of Fe3O4 nanoparticles effectively controlled magnetic interactions and anisotropy.

Summary: This paper presents a theoretical investigation on a new actuator design using anisotropic colloidal particles grafted with stimuli-responsive polymer chains. These artificial muscles combine the osmotic actuation principle of hydrogels with the structural alignment of colloidal liquid crystals for directional motion. The study identifies the solubility, degree of polymerization, salt concentration, and grafting density of the polymer chains as important factors for actuator performance and tunability. Computational results suggest that the proposed material matches or exceeds the performances of natural muscles, providing guidelines for the realization of artificial muscles with predefined actuation properties.

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.
