Water-Mediated Proton Hopping Mechanisms at the SnO(110)/HO Interface from Ab Initio Deep Potential Molecular Dynamics.

The interfacial proton transfer (PT) reaction on the metal oxide surface is an important step in many chemical processes including photoelectrocatalytic water splitting, dehydrogenation, and hydrogen storage. The investigation of the PT process, in terms of thermodynamics and kinetics, has received considerable attention, but the individual free energy barriers and solvent effects for different PT pathways on rutile oxide are still lacking. Here, by applying a combination of ab initio and deep potential molecular dynamics methods, we have studied interfacial PT mechanisms by selecting the rutile SnO(110)/HO interface as an example of an oxide with the characteristic of frequently interfacial PT processes.

The cytotoxicity of photoexcited CdS in an E. coli-CdS hybrid system and the roles of the sacrificial agent to reduce this toxic effect.

This study investigates the biosynthesis of CdS nanoparticles (NPs) by Escherichia coli CD-2 to develop an E. coli-CdS hybrid system. The hybrid system was exposed to light in the presence and absence of cysteine (Cys) as a sacrificial agent.

PTX3-assembled pericellular hyaluronan matrix enhances endochondral ossification during fracture healing and heterotopic ossification.

Endochondral ossification (EO) is a pivotal process during fracture healing and traumatic heterotopic ossification (HO), involving the cartilaginous matrix synthesis and mineralization. Unlike the extracellular matrix, the hyaluronan (HA)-rich pericellular matrix (PCM) directly envelops chondrocytes, serving as the frontline for extracellular signal reception and undergoing dynamic remodeling. Pentraxin 3 (PTX3), a secreted glycoprotein, facilitates HA matrix assembly and remodeling.

Correlation between ultrasonography and elastography parameters and molecular subtypes of breast cancer in young women.

Objective: To explore the differences of conventional ultrasound characteristics, elastic imaging parameters and clinicopathological characteristics of distinct molecular subtypes of breast cancer in young women, and to identify imaging parameters that exhibited significant associations with each molecular subtype.

Methods: We performed a retrospective analysis encompassing 310 young women with breast cancer. Observations were made regarding the ultrasonography and elastography characteristics of the identified breast lesions.

The trajectory of wetland change in China between 1980 and 2020: hidden losses and restoration effects.

Understanding wetland change is critical to establishing and implementing international conservation and management conventions. With such knowledge, supporting sustainable development, making management decisions, improving policies, and conducting scientific research become possible. However, consistent information on changes in Chinese wetlands has been unavailable.
