NONLINEAR DYNAMICS OF A PENDULUM EXCITED BY A CRANK-SHAFT-SLIDER MECHANISM

, 2015
In this analysis, we consider the dynamics of a pendulum under vertical excitation of a crank-shaft-slider mechanism. The nonlinear model approaches that of a classical parametrically excited pendulum when the ratio of the length of the shaft to the ...

A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

EcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

Lattice and Surface Engineering of Transition Metal Oxide Photoanodes for Efficient Photoelectrochemical Water Splitting

EcoEnergy, EarlyView.
This review highlights phase control, facet control, and atomic vacancy engineering as key strategies to enhance charge transport, light harvesting, and surface activity in PEC photoanodes. ABSTRACT Photoelectrochemical (PEC) water splitting is a promising approach for converting solar energy into hydrogen, yet the performance of transition metal oxide
