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

A Freestanding Multifunctional Interlayer Based on Fe/Zn Single Atoms Implanted on a Carbon Nanofiber Membrane for High-Performance Li-S Batteries

open access: yesBatteries, 2023
By virtue of the high theoretical energy density and low cost, Lithium–sulfur (Li-S) batteries have drawn widespread attention. However, their electrochemical performances are seriously plagued by the shuttling of intermediate polysulfides and the slow ...

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.

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.

Effect of Varying the Ratio of Carbon Black to Vapor-Grown Carbon Fibers in the Separator on the Performance of Li–S Batteries

open access: yesNanomaterials, 2019
Lithium–sulfur (Li–S) batteries are expected to be very useful for next-generation transportation and grid storage because of their high energy density and low cost.

Effect of the Side Walls of a Shuttle on the Tension of Weft Withdrawn from the Shuttle

open access: yesJournal of the Textile Machinery Society of Japan, 1958
Tension withdrawn from a shuttle is affected by the number of winds per traverse, by the hardness of the yarn layers, by the length and location of the pirn, by the eyelet of the shuttle, by the velocity of withdrawal from the shuttle and by the side walls of the shuttle.

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 ...

The Effect of the Side Walls of the Shuttle on the Tension of the Weft withdrawn from the Shuttle

open access: yesJournal of the Textile Machinary Society, 1957
研究目的緯糸解舒時の張力は, ワインド数, 糸層の硬さ, 木管の長さ, 部位, シヤットルのアイレット, 解舒速度, シヤットル側壁等に影響されるが, この中でバルーニングによる影響とシヤットル側壁の影響を区別して調べてみた.研究結果解舒速度が増加する程バルーニングによる張力は増加するはずで.側壁が全くなければ速度の2乗に比例するはずと思われるが, 実験結果はそれよりも常に小さな値となり, 側壁による摩擦の影響の方が遙かに大きいことがわかった.
