Mathematical Modelling of Hydromagnetic Convection from a Rotating Sphere with Impulsive Motion and Buoyancy Effects

Nonlinear Analysis, 2006
The convective heat transfer on a rotating sphere in the presence of magnetic field, buoyancy forces and impulsive motion is examined theoretically and numerically in this paper.

Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors

Advanced Functional Materials, EarlyView.
This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).

Thermal characterization of porous longitudinal rectangular moving fin wetted with GO-MoS2-Al2O3/C2H6O2-H2O ternary hybrid nanofluid

Cogent Engineering
This study examines the flow properties of a ternary hybrid nanofluid composed of GO-MoS2-Al2O3 in a base mixture of C2H6O2-H2O (50%–50%) fluid as it moves through a porous longitudinal rectangular fin.

Selective Membrane for Non‐Aqueous Electrochemical Flow Cells

Advanced Functional Materials, EarlyView.
Sulfonated fixed charge functionalization is increased to improve the conductivity of a cation exchange membrane in a non‐aqueous electrochemical cell. Based on ex situ analyses, the material achieved the highest selectivity for this type of system to date.

Representing Equilibrium and Nonequilibrium Convection in Large-Scale Models

, 2014
A new diagnostic convective closure, which is dependent on convective available potential energy (CAPE), is derived under the quasi-equilibrium assumption for the free troposphere subject to boundary layer forcing.

Metamaterial Adhesives‐Integrated Triboelectric Nanogenerators with Enhanced and Programmable Charge Generation and Adhesion

Advanced Functional Materials, EarlyView.
A metamaterial adhesive‐integrated triboelectric nanogenerator (MetaAdh‐TENG) that integrates nonlinear cuts and a TENG in a flexible adhesive film is presented. The MetaAdh‐TENG simultaneously provides enhanced charge generation and strong adhesion by controlling crack propagation during peeling.

Parameterization of convective clouds, mesoscale convective systems, and convective-generated cirrus [PDF]

, 1992
A level 2.5w deep convection updraft/downdraft parameterization scheme has been refined and tested against 3D simulations of sea-breeze generated convection over S. Florida. Cases for explicit simulation of MCSs in mid-latitudes and tropics have been encouraging.
