Summary: By adding a small amount of CNTs to a-MoO3 through a one-step hydrothermal process, the researchers solved the problems of low conductivity, slow reaction kinetics, and large volume change during Li+ ions intercalation and deintercalation. The presence of CNTs in the a-MoO3/CNTs composite resulted in a larger interlayer spacing, providing more active sites and faster reaction kinetics for lithium storage. Additionally, CNTs formed a three-dimensional conductive network, enhancing the electrical conductivity of the composite and mitigating structural fragmentation caused by volume expansion.

Summary: Recently, Prussian blue analogues (PBAs) have attracted considerable attention as efficient battery-type electrode materials for advanced hybrid supercapacitors. In this study, carbon nanotubes- (CNTs) and carbon nanofibers- (CNFs) hybridized NiHCC nanocomposites were successfully synthesized using a single-step hydrothermal process for investigating their battery-type electrochemical storage behavior in 3 M KOH. The synthesized electrodes exhibited battery-type charge storage mechanisms with excellent stability. Specifically, the NiHCC-CNT composite (NiHCC@CNT) electrode showed outstanding charge storage capacity (348 mAh g-1 at 1 Ag-1) due to its high electrochemically active surface area, low charge transfer resistance, and efficient utilization of redox centers for K+ ion storage. Furthermore, the hybrid capacitor constructed with NiHCC@CNT demonstrated excellent cycling stability over 5000 cycles, with a maximum energy density of 59 W h Kg- 1 at a power density of 1798 W Kg-1. This work highlights the potential of NiHCC@CNT composite as a cathode material for K+ ion supercapacitors.

Summary: Semiconductor photocatalytic materials have potential in antifouling applications due to their antibacterial properties, stability, and nontoxic nature. This study introduces g-C3N4/TNTs/CNTs (CNTC) photocatalytic composite powders into polydimethylsiloxane (PDMS) coatings to enhance their antifouling performance. The results show successful recombination of CNTC, which resulted in decreased recombination rate of photogenerated carriers. The addition of CNTC increased the hydrophobicity and roughness of the coatings while reducing the surface energy. CNTC effectively improved the anti-attachment performance of PDMS coatings to bacteria and benthic diatom.

Summary: The ability of water to dissolve biomolecules is crucial for our life. The behavior of water in the hydration shell of proteins has a significant impact on the structure and function of the protein. However, there is still no consensus on whether protein promotes or destroys the structural order of water in its hydration shell. In this study, molecular dynamics simulations and analysis of the hydrogen-bond structure were performed on lysozyme protein in water, revealing that the protein promotes local structural ordering of the hydration water while having a negligible effect on the strength of individual H-bonds. These findings have fundamental implications for the structure and function of biomolecules and provide new insights into the hydration of proteins in water.

Summary: The self-trapped excitons (STEs) in soft van der Waals (vdW) materials have attracted tremendous attention. Conventional methods for manipulating STEs involve introducing permanent defects or lattice distortions, which suppress the inherent structures and properties. A non-destructive method of achieving highly tunable room temperature STEs is therefore of strategic interest. By stacking 2D materials to form vdW heterostructures, many-body interactions are introduced and can be exploited to control STE emissions. Highly tunable STE emissions have been demonstrated in vdW heterostructures composed of lead iodide, hexagonal boron nitride, or molybdenum oxide. The synergistic effect of dielectric screening and interfacial many-body interaction improves the temperature characteristic and emission properties of STEs. Strong STE emissions with highly tunable center energies in a broadband spectrum range have been verified at room temperature. This work provides a non-destructive method for manipulating room temperature STE emissions in rigid lattice vdW materials, opening up the potential for STEs in next-generation optoelectronics.
