Summary: Integrative neural interfaces combining neurophysiology, optogenetics, and neural imaging offer opportunities for studying neural circuits in the brain. The development of ultra-flexible, highly conductive and fully transparent microscale electrocorticogram (mu ECoG) electrode arrays with PEDOT:PSS-ITO-Ag-ITO assembly shows enhanced mechanical flexibility, robustness, and resilience to photon-induced artifacts. In vivo experiments demonstrate successful recording of light-evoked ECoG oscillations from the primary visual cortex (V1) of an anesthetized rat.

Summary: This study investigates the biodegradation of N-methyl pyrrolidone (NMP) in activated sludge and identifies the factors that enhance its degradation. It finds that prolonged acclimation of biomass with NMP improves NMP biodegradation, and specific bacteria isolated from the acclimated biomass can significantly accelerate NMP degradation in activated sludge. Additionally, the study identifies monomethylamine as a key intermediate that limits the mineralization of NMP and demonstrates that enhancing its removal can expedite NMP biodegradation.

Summary: In this study, a blue transparent micro-LED display with a chip size of 20 μm × 20 μm, a pixel density of 152 PPI, a pixel spacing of 150 μm, and a resolution of 64 × 32 has been successfully fabricated. ITO/Ag/ITO transparent layers were deposited by high-power impulse magnetron sputtering. The electrical properties of the indium tin oxide (ITO) layers were analyzed using sheet resistance, while surface morphology was examined using scanning electron microscopy, transmission electron microscopy, and atomic force microscopy. The results show that the ITO/Ag/ITO structure with 20 nm thick Ag has a lower sheet resistance (3.36 Cl/sq) and sufficient visible light transmittance (80.45%). The visible light transmittance of the ITO/Ag/ITO layers increased to 86% after rapid thermal annealing. Furthermore, surface roughness was minimized and sheet resistance was further reduced, resulting in ohmic contact on n-GaN for transparent micro-LED display applications.

Summary: The solubility of sulfadiazine in {N-methyl-2-pyrrolidone (NMP) + water} mixtures was determined and correlated using the Jouyban-Acree model from 278.15 K to 313.15 K. Discontinuous solubility trends were observed in NMP-rich mixtures at low temperatures. Enthalpy-entropy relationships were found to be non-linear, with sulfadiazine preferentially solvated by water molecules in water-rich mixtures and NMP molecules in mixtures 0.17 < x(1) < 1.00 at 313.15 K.

Summary: This study developed three types of optically transparent coatings to improve the wear-resistance and sand erosion abilities of ITO-coated PMMA substrates. Results showed that PU topcoats greatly enhanced sand erosion properties, surpassing acrylic and silicone topcoats, attributed to their good toughness and self-healing properties. Additionally, high hardness and good Taber abrasion properties of the ITO films and silicone topcoats did not have a significant impact on sand erosion abilities due to their brittleness and irreparable 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: 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.
