Nano-Metal-Organic Frameworks Isolated in Mesoporous Structures.

As an alternative to bulk counterparts, metal-organic framework (MOF) nanoparticles isolated within conductive mesoporous carbon matrices are of increasing interest for electrochemical applications. Although promising, a "clean" carbon surface is generally associated with poor compatibility and weak interactions with metal/ligand precursors, which leads to the growth of MOFs with inhomogeneous particle sizes on outer pore walls. Here, a general methodology for in situ synthesis of eight nanoMOF composites within mesochannels with high dispersity and stability are reported.

Maximizing Output Energy via Suppressing Charge Loss and Increasing Load Voltage in Charge Extraction Process.

The effective collection of interfacial tribo-charges and an increase in load voltage are two essential factors that improve the output energy of triboelectric nanogenerators. However, some tribo-charges are hardly collected through one or multiple integrated side electrodes based on corona discharge, and their load voltages are limited by air breakdown in adjacent electrodes. In this study, a dynamic quasi-dipole potential distribution model is proposed to systematically reveal the mechanisms of interfacial tribo-charge loss.

Stabilizing Layered Oxide Cathodes Based on Universal Surface Residual Alkali Conversion Chemistry for Rechargeable Secondary Batteries.

Diatomite-Based Hybrid Electrolyte for Improving Reversibility of Cathode/Anode Interface Reaction in Zn-MnO Batteries.

The cyclic stability of aqueous zinc-manganese batteries (ZMBs) is greatly restricted by the side reaction of the anode and the irreversibility of the cathode. In this work, a solid-liquid hybrid electrolyte mixing by traditional ZnSO-based electrolyte and diatomite (denoted as Dtm) is proposed that exhibits good compatibility and reversibility in both the anode interface and the cathode interface. The abundant hydroxyl groups at the anode interface disturb the hydrogen bond network of water molecule, which weakens the corrosion of the active water to Zn anode.

A modelling approach to characterise the interaction between behavioral response and epidemics: A study based on COVID-19.

During epidemic outbreaks, human behavior is highly influential on the disease transmission and hence affects the course, duration and outcome of the epidemics. In order to examine the feedback effect between the dynamics of the behavioral response and disease outbreak, a simple SIR- type model is established by introducing the independent variable of effective contact rate, characterizing how human behavior interacts with disease transmission dynamics and allowing for the feedback changing over time along the progress of epidemic and population's perception of risk. By a particle swarm optimization algorithm in the solution procedures and time series of COVID-19 data with different shapes of infection peaks, we show that the proposed model, together with such behavioral change mechanism, is capable of capturing the trend of the selected data and can give rise to oscillatory prevalence of different magnitude over time, revealing how different levels of behavioral response affect the waves of infection as well as the evolution of the disease.

-Glucan-modified nanoparticles with different particle sizes exhibit different lymphatic targeting efficiencies and adjuvant effects.

Particle size and surface properties are crucial for lymphatic drainage (LN), dendritic cell (DC) uptake, DC maturation, and antigen cross-presentation induced by nanovaccine injection, which lead to an effective cell-mediated immune response. However, the manner in which the particle size and surface properties of vaccine carriers such as mesoporous silica nanoparticles (MSNs) affect this immune response is unknown. We prepared 50, 100, and 200 nm of MSNs that adsorbed ovalbumin antigen (OVA) while modifying -glucan to enhance immunogenicity.
