Summary: Nylon 6/6 and ZnO/nylon 6/6 nanocomposite films were prepared by solvent casting method. The morphological study showed better dispersion of ZnO NPs in nylon 6/6, but agglomerations were found with high filler quantities. The incorporation of nanoparticles decreased the thermal stabilities of neat nylon 6/6 films and slowed down the crystallization rate, as observed in DSC study.

Summary: The properties of carbon nanotubes can be modified by adding metal nanoparticles to their surface. This is achieved by first functionalizing the CNTs with oxygen groups using plasma, followed by decorating them with Ni-Pd bimetallic nanoparticles using plasma sputtering deposition. The oxygen groups act as nucleation sites for the growth of the bimetallic nanoparticles. The resulting Ni-Pd nanoparticle-decorated CNTs are then evaluated for their sensing capabilities in detecting toluene.

Summary: This study prepared highly dispersed bimetallic NiCoP NPs supported by N-doped graphene-like material as an efficient electrocatalyst for water oxidation. This designed electrocatalyst showed excellent OER catalytic performance, and the increased activity of NiCoP-3@GL may be attributed to the increase in surface area caused by irregular morphology, rich interface contact, and porous structure. Additionally, the strong combination of NiCoP and GL improved the structural stability and durability of the electrocatalyst.

Summary: This work investigates the photocatalytic degradation of alizarin red using Cu-doped manganese oxide nanomaterials as catalysts under UV light irradiation. The synthesized nanoparticles, with Cu-doped manganese oxide as the catalyst, exhibited high efficiency in the degradation of alizarin red, with MH20 showing the highest degradation rate. The results indicate the potential of Cu-doped manganese oxides as effective catalysts for the removal of alizarin red.

Summary: In this study, N-doped graphene-like supported highly dispersed bimetallic NiCoP NPs were prepared as an efficient electrocatalyst for water oxidation. The designed electrocatalyst showed excellent OER catalytic performance with high overpotential and Tafel slope, attributed to its irregular morphology, rich interface contact, and porous structure. The combination of NiCoP and GL improved the structural stability and durability of the electrocatalyst, but its performance decreased after 5000 cyclic voltammetry tests.

Summary: This study presents the synthesis and characterization of MoO3 and zirconium doped MoO3 nanoparticles using the hydrothermal method. The results show the successful doping of zirconium into the host lattice of MoO3, with its concentration affecting the band-gap energy. The doped nanoparticles exhibit lower electron-hole recombination rates, which is important for photocatalysis. Additionally, the doping of zirconium enhances the visible light photodegradation of Alizarin red S.

Summary: Continuous advancements in science and technology have led to the discovery of a new class of flexible transparent conductive films (FTCFs) called two-dimensional (2D) metal aerogels. A new large-scale self-assembly synthesis of bimetallic Pt-Ni 2D metal aerogels with controllable morphology is described in this study. The synthesized 2D aerogels form percolating nanoscale networks with low sheet resistances (down to 270 Cl/sq) and reduced optical transparency. These 2D bimetallic Pt-Ni aerogels not only expand the diversity of metal aerogels but also offer potential for applications in flexible electronics and electrocatalysis with lower production costs.

Summary: Graphite carbon nitride (g-C3N4) is a promising photocatalyst with high catalytic activity, low cost, and high biosafety. However, its application in water purification is limited due to the complexity of underwater photochemical reaction conditions and the disadvantages of g-C3N4 itself. To improve its underwater photocatalytic performance, researchers prepared a g-C3N4/carbon nanotubes (CNT-CN) composite photocatalyst with high specific surface area and enhanced light absorption capacity, which showed significantly improved photodegradation efficiency under different underwater transmission light.

Summary: Using rational design, we developed a 17 kDa cyanobacteriochrome-based near-infrared (NIR-I) fluorescent protein, miRFP718nano, which efficiently binds endogenous biliverdin chromophore and emits bright fluorescence in mammalian cells and tissues. With a maximal emission at 718 nm and an emission tail in the short-wave infrared (SWIR) region, miRFP718nano enables deep-penetrating off-peak fluorescence imaging in vivo. We demonstrated the superiority of miRFP718nano-enabled SWIR imaging in various applications, including imaging of microbes in the mouse digestive tract, mammalian cells injected into the mouse mammary gland, and NF-kB activity in a mouse model of liver inflammation.

Summary: This study compares the characteristics of water-soluble dye alizarin red S (ARS) nanoparticles, ARS in aqueous solution, and alizarin in DMSO using femtosecond technology. The results show slight differences in the stationary absorption spectra between nanoparticles and solution. Excitation at 530 nm leads to weak and noisy responses, and transient spectra of the nanoparticles at 267 nm were recorded. The [La(OH)(2)][ARS] nanoparticles in aqueous solution exhibit a fast relaxation process of 14 ps after excitation at 530 nm, similar to Na(ARS) solution (19 ps).

Summary: This paper reports a carbon skeleton-coated bimetallic sulfide derived from metal-organic frameworks (MOFs) that was used as a cathode catalyst for rechargeable zinc-air batteries (ZABs). The prepared (Co,Fe)S-2/CNS catalysts exhibited excellent electrochemical properties in alkaline solutions, showing a low potential difference, high specific capacity, and good charge-discharge cycling performance. These findings suggest a promising application prospect of (Co,Fe)S-2/CNS catalysts in the field of ZABs.
