Polaronic effects in electron shuttling [PDF]

open access: yesLow Temperature Physics, 2009
A shuttle-like mechanism of electron transport through a single level vibrating quantum dot is considered in the regime of strong electromechanical coupling. It is shown that the increment of shuttle instability is a nonmonotonic function of the driving voltage.

Catalytic Effects in Lithium-Sulfur Batteries: Promoted Sulfur Transformation and Reduced Shuttle Effect. [PDF]

open access: yesAdv Sci (Weinh), 2018
AbstractLithium–sulfur (Li–S) battery has emerged as one of the most promising next‐generation energy‐storage systems. However, the shuttle effect greatly reduces the battery cycle life and sulfur utilization, which is great deterrent to its practical use. This paper reviews the tremendous efforts that are made to find a remedy for this problem, mostly

Bax shuttling after neonatal hypoxia–ischemia: Hyperoxia effects [PDF]

open access: yesJournal of Neuroscience Research, 2008
AbstractPerinatal hypoxia–ischemia (HI) occurs in 0.2%–0.4% of all live births, with 100% O2 resuscitation (HHI) remaining a standard clinical treatment. HI produces a broad spectrum of neuronal death phenotypes ranging from a more noninflammatory apoptotic death to a more inflammatory necrotic cell death that may be responsible for the broad spectrum ...

Rapid directional change degrades GPS distance measurement validity during intermittent intensity running.

open access: yesPLoS ONE, 2014
Use of the Global Positioning System (GPS) for quantifying athletic performance is common in many team sports. The effect of running velocity on measurement validity is well established, but the influence of rapid directional change is not well ...

Theoretical calculation guided materials design and capture mechanism for Zn–Se batteries via heteroatom‐doped carbon

open access: yesCarbon Neutralization, 2022
Zinc–selenium (Zn–Se) batteries have generated great research interest because they could potentially meet the requirements of a high‐capacity, high energy density storage device. Unfortunately, efforts to control the shuttle effect of polyselenides have

Boosting sulfur‐based cathode performance via confined reactions in covalent organic frameworks with polarized sites

open access: yesBattery Energy, 2023
The widespread promotion of the sulfur‐based cathode is continuously threatened by the dissolution or slow kinetic reactions of polysulfides, resulting in a deterioration of capacity and volume expansion.

Blood lead levels, pulmonary function and agility in Polish schoolchildren

open access: yesAnnals of Human Biology, 2017
Background: Reduced vital capacity (VC) and forced vital capacity (FVC) are associated with lead (Pb) exposure. Aim: The objective of this study is to analyse the effects of Pb on FVC and the shuttle run performance.

Boron Nitride Nanotube-Based Separator for High-Performance Lithium-Sulfur Batteries

open access: yesNanomaterials, 2021
To prevent global warming, ESS development is in progress along with the development of electric vehicles and renewable energy. However, the state-of-the-art technology, i.e., lithium-ion batteries, has reached its limitation, and thus the need for high ...
