Summary: An improved understanding of the brain's neuroplastic potential has led to advancements in neuromodulatory treatments for acute stroke patients. However, there is still limited knowledge about individual differences in treatment response and recovery. This study used personalized connectivity analyses to identify unique recovery trajectories in response to repetitive transcranial magnetic stimulation (rTMS) treatment. The results demonstrated the feasibility of using individualized connectivity analyses to differentiate phenotypes and better understand patient recovery with neuromodulatory treatment.

Summary: Groundwater can be contaminated by both organic micropollutants and inorganic heavy metals. Advanced nanomaterials, such as nano-calcium peroxide (nano-CaO2), have been developed for the effective remediation of these contaminants. The study investigated the simultaneous removal of p-nitrophenol (PNP) and cadmium (Cd) using nano-CaO2 and Fe(II) catalysis. The results demonstrated high removal rates for both contaminants, with hydroxyl radicals and singlet oxygen being the major reactive species. The study provides new insights into the remediation of multiple contaminants in groundwater.

Summary: This study introduces a simple, bottom-up method to create chiral, inorganic structures by co-assembly of TiO2 nanorods and cellulose nanocrystals (CNCs) in water, which possess unique electronic, magnetic, and optical properties relevant to various applications. A phase diagram was constructed to guide experimental efforts and a lyotropic cholesteric mesophase was observed over a wide composition range. The high loading of TiO2 nanorods enables the fabrication of inorganic, free-standing chiral films through water removal and calcination. This new approach separates sol-gel synthesis from particle self-assembly using low-cost nanorods, different from the traditional templating method using CNCs.

Summary: When a metal nanoparticle absorbs light, it undergoes a series of relaxation processes that lead to transient modifications in its optical response. By using time-resolved spectroscopy experiments, it was shown that the transient optical response could be attributed to internal thermalization processes within the nanoparticle, and the effects of electron and ionic lattice heating were quantitatively studied. The study demonstrated the possibility of selectively probing electronic or lattice dynamics by choosing specific probe wavelengths, and showed that the timedependent spectral shape of transient extinction cross-section changes was successively dominated by electron and lattice heating effects.

Summary: The charged facets of a nanocrystal can form nanometer-size electric dipoles, and by adjusting the spacing between these dipoles, the dipolar interaction energy can be controlled to switch on or off the growth of nanorods. This kinetically controlled growth is achieved at relatively low reaction temperatures, resulting in branchless nanorods with good photoluminescence characteristics.

Summary: Diversification and incorporation of biopolymers are important for optimizing biomaterials. The shell of Pulleniatina obliquiloculata, a planktonic foraminifer, exhibits a unique mesocrystal architecture. The shell formation involves the crystallization of a primary organic sheet, which consists of blocky and dendritic-fractal crystals with twinning. The formation of these crystals is influenced by high supersaturation and growth competition. Furthermore, alignment of the crystallographic c-axis is induced by biopolymers in the primary organic sheet. The factors contributing to the formation of calcite in Pulleniatina obliquiloculata are discussed.

Summary: Efficient heterojunction photocatalysts with spatial separation of photogenerated carriers are crucial to photo-catalysis. The unique carbonized polymer dots/ZnIn2S4 (CPDs/ZIS) Z-scheme heterojunction is designed to realize efficient spatial directional separation of photogenerated carriers and deliver enhanced photocatalytic performance in pollutant degradation. The CPDs generate more superoxide radicals to facilitate mineralization of organic pollutants and retain more holes for oxidation, while the Z-scheme migration mechanism of photogenerated carriers in the CPDs/ZIS composite preserves the original valence band potential of ZIS.

Summary: Micro-arc oxidation (MAO) was used to treat Ti-6Al-4V electron-beam-welded joints, and the effects on microstructure, phase composition, and corrosion resistance of the joint and surface coating were studied. The MAO treatment resulted in a phase transformation in the joint and a denser and thicker coating. The XRD analysis confirmed the presence of rutile and anatase phases in the coating. The corrosion tests showed a significant decrease in corrosion current density and an improvement in corrosion resistance due to the MAO treatment. Long-term exposure to a high-stress corrosion environment also revealed the formation of a protective layer on the joint.

Summary: The construction of heterostructures using atomic layer deposition and high-energy metal plasma implantation has a significant impact on the catalytic activity of cobalt oxide in the oxygen evolution reaction (OER). Among different metals, the heterostructure constructed with cobalt oxide and zirconium metal exhibits better OER activity than silver, titanium, and chromium metals. Increasing the number of zirconium atoms and the thickness of the cobalt oxide layer initially enhances the OER activity and then gradually decreases it. The Zr500/12CoO metal-semiconductor heterojunction has a higher barrier height and more electron-hole pairs, leading to a more positively charged metal surface and promoting the adsorption of OH-. The construction of metal-semiconductor heterojunctions provides insights into the design and surface-interface modification of efficient, low-cost, and durable electrodes for water splitting applications.

Summary: A novel terahertz anti-resonant fiber is designed with high-resistivity silicon in the fiber and nested double-layer U-shape tubes, which effectively reduce the transmission loss. The fiber's confinement loss and effective material loss are analyzed and optimized using the finite element method. The optimized fiber demonstrates a low total loss of 3.1 x 10-3 dB/m at 1 THz and a low-loss transmission bandwidth of 0.44 THz in the range of 0.5-1.5 THz. Bending analysis shows that the bending loss is less than 2.1 x 10-2 dB/m at 1 THz for bending radii bigger than 60 cm. This anti-resonant fiber exhibits excellent performance and holds high commercial potential in terahertz waveguides.
