Summary: In this study, a flower-like PtNi bimetallic particle anchored on TiO2 nanotube arrays (PtNi/TNTs/Ti) was synthesized as an anode catalyst for methanol oxidation reaction (MOR) in direct methanol fuel cells (DMFCs). The PtNi/TNTs/Ti electrode exhibited high electrocatalytic activity and durability, with PtNi100/TNTs/Ti showing a four-fold increase in mass activity compared to Pt100/TNTs/Ti electrodes. The improved catalytic performance of PtNi was attributed to lattice compression and enhanced OH adsorption. This simple method holds promise for energy and environmental applications.

Summary: Platinum-free electrocatalysts for methanol oxidation were developed using highly ordered porous titanium dioxide nanotubes (TNTs) decorated with solely NiO (TNi) or functionalized with NiO/graphene (TNiG). XRD confirmed the formation of anatase phase in the composite with NiO and graphene, while Raman spectra revealed anatase peaks alongside the D and G bands of graphene. The ultrafine structure of TNTs with uniformly dispersed spherical Ni species was shown by SEM images, with an average diameter of 50 nm and tube lengths ranging from 580 to 640 nm. XPS spectra confirmed the existence of Ni (OH)2 and NiOOH, as well as metallic Ni on the TNT surface. The methanol oxidation test demonstrated that TNiG exhibited a higher current density of 73.6 mA/cm2 compared to 36.7 mA/cm2 for TNi, attributing to the high surface coverage and surface modification of TNT with Ni and G.

Summary: By fine-tuning the doping amount of phosphorus atoms, PdSnP nanocatalysts with different compositions were synthesized, and it was found that the doping of phosphorus atoms changed the composition and microstructure of PdSn nanocatalysts, forming amorphous and crystalline multiphase structures. This multiphase nanostructure with abundant interfacial defects effectively promoted the electrocatalytic oxidation efficiency of Pd atoms in small-molecule alcohols. Compared with undoped PdSn nanocatalysts and commercial Pd/C catalyst, the mass and specific activities of PdSn0.38P0.05 nanocatalysts in methanol oxidation reaction were significantly increased.

Summary: The surface fluorinated nickel-graphene nano-composites synthesized via reduction of Si-H bonds in hydrothermal condition exhibit higher activity and kinetics for methanol oxidation reaction (MOR). The introduction of fluorine leads to the formation of nickelic, decreasing the reaction energy barrier for MOR. The strong electronegativity of fluorine atoms facilitates the attraction of OH- groups and repulsion of protons, contributing to the enhanced performance of F-Ni-G nanocomposites as MOR catalysts.

Summary: Alarm signals and cues are crucial for animal survival and vary among species. This study found that disturbance odors did not significantly trigger avoidance behavior in red webbed treefrogs. However, the sympatric predator, Chinese green tree vipers, showed a significant response to disturbance odors and exhibited a higher tongue-flick rate. These findings suggest that eavesdropping predators can exploit disturbance odor cues to detect prey.

Summary: This study investigates the intercellular mechanical properties and energetic costs during cell-cell collective migration in confined microchannels. The research reveals that cells adapt to different confinement environments by regulating intercellular force, which confirms the relationship between collective cell migration and cell-cell junctions. The observations of cell orientation, actomyosin contractility, energetic costs, and glucose uptake provide a reasonable explanation for cell-force driven migration in various confined environments. The study also finds that under highly confined conditions, the intercellular force and energetic costs are greater, leading to a more orderly cell orientation during collective migration.

Summary: This study attempted to assess the likelihood of organophosphate esters (OPEs) inducing biological effects in humans by integrating physiologically based pharmacokinetic (PBPK) models and in vitro bioassays. The total exposure level of OPEs for Chinese residents was determined, and human PBPK models were developed to predict their concentrations in human tissues. The study proposes a new framework to improve health risk assessment of contaminants without sufficient toxicity data and decrease the need for animal experimentation.

Summary: The fast finite-time consensus problem of multi-agent systems under diverse topologies is investigated using a hybrid linear and fractional power protocol. The protocol improves convergence performance when the state is far from the equilibrium and accelerates convergence process when the state is close to the equilibrium. It achieves a faster convergent rate compared to individual asymptotic or finite-time consensus protocols. The leaderless multi-agent systems are studied under undirected topology, and then extended to the leader-following case under directed networks. The protocols are validated through numerical simulations.

Summary: In this study, we developed a reliable method to accurately determine the copy number of STRC based on standard short-read genome sequencing data, which has clinical significance in the screening and diagnosis of genetic hearing loss. Our population analysis revealed that 5.22% of the general population has copy number changes in STRC, almost half of which are clinically significant, including heterozygous and homozygous deletions of STRC. Additionally, we provided population-based evidence of pseudogene-mediated gene conversions between STRC and STRCP1.

Summary: The aim of this study was to explore the predictive role of microRNAs (miRNAs) from maternal serum exosomes in early recurrent pregnancy loss (RPL) and the related mechanism in early pregnancy. Differential expression of miRNAs was identified through RNA sequencing and qRT-PCR, and miR-185-5p was found to be increased in RPL patients and could serve as a biomarker for subsequent miscarriage. Moreover, miR-185-5p in exosomes reduced VEGF expression of dNK cells.

Summary: The concomitant pollution of arsenic and antibiotics has been commonly observed in recent environments, and their behavior may differ from when they exist individually. Colloidal ferric hydroxide (CFH) is found ubiquitously in various environments and in this study, it was shown to facilitate the degradation of oxytetracycline (OTC) and the reduction of Fe(III) to Fe(II). Under oxygen-rich conditions, reactive oxygen species (ROS) such as (OH)-O• and O2•- were generated through the reactions between dissolved oxygen (DO) and Fe(II). It was found that (OH)-O• played a dominant role in the oxidation of As(III). Furthermore, the oxidation of As(III) to As(V) resulted in the formation of ferric arsenate, which significantly reduced the risks of As(III) in the environment. Similar transformations were also observed with other iron oxides and different antibiotics. These findings contribute to our understanding of the role of organic pollutants in combined contamination.

Summary: In this study, the IKK gene, CfIKK3, was cloned and characterized in the Zhikong scallop Chlamys farreri. The expression of CfIKK3 was found to be ubiquitous in all tested scallop tissues and significantly induced after challenge with various pathogen-associated molecular patterns. Co-immunoprecipitation assays confirmed the interaction between CfIKK3 and key adaptors in the TLR and RLR pathways, indicating its crucial role in the scallop innate immune signal transduction. Moreover, overexpression of CfIKK3 activated the NF-kappa B reporter gene in a dose-dependent manner.
