Inorganic-organic separators for alkaline batteries [PDF]

, 1978
A flexible separator is reported for use between the electrodes of Ni-Cd and Ni-Zn batteries using alkaline electrolytes. The separator was made by coating a porous substrate with a battery separator composition.

Investigation of sample handling steps for accurate heparan sulphate disaccharide analysis using HPLC–MS

ELECTROPHORESIS, EarlyView.
Abstract Heparan sulphates (HSs), a specific class of glycosaminoglycans (GAGs), are important participants of cellular signalling. Analytical characterization of GAGs requires a complex sample preparation workflow. Although a detailed stability and recovery study is available for the chondroitin sulphate GAG class, the literature concerning HS is ...

Characterisation of Hedge Burning in the Context of Wildland Urban Interface (WUI) Fire Prevention

Fire and Materials, EarlyView.
ABSTRACT With global warming, the wildfire season tends to get longer, causing fatalities and devastating damage to human property. Although many countries have implemented fire risk prevention measures, particularly in Wildland Urban Interfaces (WUI), this finding shows that there are weaknesses in the prevention measures. This is mainly due to a lack

Morphological, Physico‐Chemical, and Thermal Characterization of Non‐Reactive Protective Materials for Steel Structures

Fire and Materials, EarlyView.
ABSTRACT This study addresses the critical issue of fire safety in densely populated urban areas and focuses on the resilience of new and existing buildings, with an emphasis on passive fire protection materials for steel structures. Conventional fire codes are considered potentially restrictive, which has led to research in the field of performance ...

Influence of Sidewall Effects on Ejected Flame During Facade Calibration Tests: Experimental Analysis and Findings

Fire and Materials, EarlyView.
ABSTRACT The inclusion of sidewalls is a typical architectural feature in building façades, which has raised significant concerns about their potential to accelerate flame spread, particularly with the increasing prevalence of high‐rise buildings. This paper presents an experimental investigation and analysis of façade flame with a single sidewall ...

Production and Characterization of Open Cell Cordierite from Boron and Waste Materials by Geopolymer Method for the Emission After Treatment System of Diesel Engines

Global Challenges, EarlyView.
Open porous geopolymer‐based cordierite materials are produced due to the porous structure, temperature resistance, easy and low cost applications of geopolymer. For the composition of cordierite, waste boron clay, metakaolin, fly ash and magnesium carbonate are used, while keeping the geopolymerization temperature constant, sodium silicate, sodium ...

Early Cretaceous–Late Miocene Basin–Mountains Pattern in the Northeastern Margin of the Tibetan Plateau, NW China: Evidence From Detrital Zircon Chronology in the Lanzhou Basin

Geological Journal, EarlyView.
Using DZmix and DZstats models, we quantified the contributions of potential sources of the Lanzhou basin. Our findings indicate that the Cenozoic cooling and denudation signals primarily originated from Qilian and West Qinling, which were the main sediment sources.
