We report a straightforward strategy to design efficient N doped porous carbon (NPC) electrocatalyst that has high concentration of easily accessible active sites for the CO2 reduction reaction (CO2 RR). The NPC with large amounts (pyridinic and graphitic N) highly structure is prepared by using an oxygen-rich metal-organic framework (Zn-MOF-74) precursor. amount species can be tuned optimizing calcination temperature time. Owing pore sizes, are well exposed electrolyte RR. exhibits superior...
Children's health and behaviour are essential for their development it is important to obtain abundant accurate information understand young people's behaviour. The Health Behaviour in School-aged Children (HBSC) study among the first large-scale international surveys on adolescent through self-report questionnaires. So far, more than 40 countries Europe North America have been involved HBSC study. purpose of this assess test-retest reliability selected items Chinese version survey...
Recovery of spent graphite (SG) anode has been largely overlooked and undervalued due to the difficult regeneration process relative low price compared valuable elements in cathode. Moreover, lacking feasible low-cost techniques for recovery SG seriously restricts development all-component recycling end-of-life batteries. Here, a novel in-depth purification via KOH–NaOH composite alkali etching is proposed eliminate impurities incorporated SG. Residual acid-insoluble impurities, such as Al-...
The gate dielectric layer is an important component in building a field-effect transistor.

Molybdenum oxide (MoO3)-based materials have attracted considerable attention due to their significant applications in catalysis and optoelectronics. However, the introduction of oxygen vacancies into MoO3 under working conditions inevitably results drastic changes properties performance. Therefore, it is imperative comprehend deoxidation process controlled environments. Herein, we reveal mechanisms orthorhombic using an advanced situ transmission electron microscopy technique. We found that...
Understanding the reaction and deactivation mechanism of CO2 photoreduction is critical to carbon-neutral economy. Here, we report a self-poisoning effect in accompanied by C2 production. With phosphorus-doping nitrogen-vacancy engineering, reactivity on carbon nitride can be significantly enhanced with considerable yield C2. Nevertheless, stability this catalyst decreases The originates from rigid bonding between catalysts products, slowing down desorption process poisoning catalysts. This...
Atopic dermatitis (AD), characterized by eczema as a chronic pruritic inflammatory skin disease, has become serious health problem with recurrent clinical episodes. However, current treatments have limited relief and are accompanied adverse effects. Therefore, there is necessity to develop new effective drugs for AD treatment. Angelica Yinzi (AYZ) classic ancient prescription nourishing blood, moistening dryness, dispelling wind, relieving itching. its mechanism alleviating atopic remains...
Abstract. Brown carbon (BrC) is an organic component with noticeable absorption in the ultraviolet and short visible wavelengths, which influences global radiative balance. However, assessing BrC effects remains a challenging task owing to scarcity of direct observations uncertainties regarding their chemical optical properties. This study proposes efficient method for estimating based on available observational data. The light-absorbing properties obtained from aethalometer measurements...

Heterogeneous ice nucleation on atmospheric aerosols strongly affects the earth's climate, and at microscopic level, surface-irregularity-induced crystallization behaviors are common but crucial. Because of lack visual evidence effective experimental methods, mechanism atomic-structure-dependent formation aerosol surfaces is poorly understood. Here we chose highly oriented pyrolytic graphite (HOPG) to represent soot (a primary aerosol), environmental scanning electron microscopy (ESEM) was...
The stress shielding effect caused by traditional metal implants is circumvented using polyetheretherketone (PEEK), due to its excellent mechanical properties; however, the biologically inert nature of PEEK limits application. Endowing with biological activity promote osseointegration would increase applicability for bone replacement implants. A biomimetic study performed, inspired mineralized collagen fiber bundles that contact marrow mesenchymal stem cells (BMMSCs) on native trabecular...

Abstract The nucleation and growth of bubbles within a solid matrix is ubiquitous phenomenon that affects many natural synthetic processes. However, such bubbling process almost “invisible” to common characterization methods because it has an intrinsically multiphased nature occurs on very short time/length scales.

The need of data owners for privacy protection has given rise to collaborative learning, and data-related issues heterogeneity faced by federated learning further clustered learning; whereas the traditional privacy-preserving scheme using homomorphic encryption alone fails fulfill demands learning. To address these issues, this research provides an effective safeguarded answer sharing keys among clusters in grounded conditional representative broadcast re-encryption. This method constructs a...
Mechanisms of nucleation have been debated for more than a century, despite successes classical theory. The process has recently argued as involving nonclassical mechanism (the "two-step" mechanism) in which an intermediate step occurs before the formation nascent ordered phase. However, thorough understanding this mechanism, terms both microscopic kinetics and thermodynamics, remains experimentally challenging. Here, situ observations using transmission electron microscopy on solid-state...
Nanotopography can promote osseointegration, but how bone marrow mesenchymal stem cells (BMMSCs) respond to this physical stimulus is unclear. Here, we found that early exposure of BMMSCs nanotopography (6 h) caused mitochondrial fission rather than fusion, which was necessary for osseointegration. We analyzed the changes in morphology and function located on surfaces NT100 (100 nm nanotubes) ST (smooth) by super-resolution microscopy other techniques. Then, both a significant increase on,...
