Oxygen‐Driven Structural Reorganization by Trace Water Enabling Fast Li‐Ion Transport in a Pliable Solid Electrolyte

open access: yesAdvanced Energy Materials, EarlyView.
Trace water is acting as a constructive mediator in 2LiCl–GaF3, markedly increasing ionic conductivity while reorganizing local coordination. Hydration creates localized Li+ solvation environments and partially dissociates ion pairs, enhancing Li‐ion mobility.

Thermo-mechanical behaviour of a compacted swelling clay [PDF]

open access: yes, 2008
Compacted unsaturated swelling clay is often considered as a possible buffer material for deep nuclear waste disposal. An isotropic cell permitting simultaneous control of suction, temperature and pressure was used to study the thermo-mechanical ...

The Power of Unity: Collective Action and Smallholder Agricultural Performance in West Africa

open access: yesAgribusiness, EarlyView.
ABSTRACT We analyze the impact of collective action through farmer‐based organizations (FBOs) on smallholders' farm performance and income inequality in Ghana, Benin, The Gambia, and Mali. We find that FBO membership increases cereal yield in Ghana and The Gambia, legume yield in Mali, ruminant numbers in Benin and The Gambia, and total farm income in ...

Efficiency factor and modulus of elasticity of lightweight concrete with expanded clay aggregate

open access: yesRevista IBRACON de Estruturas e Materiais
Nowadays lightweight concrete is used on a large scale for structural purposes and to reduce the self-weight of structures. Specific grav- ity, compressive strength, strength/weight ratio and modulus of elasticity are important factors in the mechanical ...

Applications for special-purpose minerals at a lunar base [PDF]

open access: yes
Maintaining a colony on the Moon will require the use of lunar resources to reduce the number of launches necessary to transport goods from the Earth. It may be possible to alter lunar materials to produce minerals or other materials that can be used for

Bayesian Optimization Guiding the Experimental Mapping of the Pareto Front of Mechanical and Flame‐Retardant Properties in Polyamide Nanocomposites

open access: yesAdvanced Intelligent Discovery, EarlyView.
Bayesian optimization enabled the design of PA56 system with just 8 wt% additives, achieving limiting oxygen index 30.5%, tensile strength 80.9 MPa, and UL‐94 V‐0 rating. Without prior knowledge, the algorithm uncovered synergistic effects between aluminum diethyl‐phosphinate and nanoclay.

Characterization, isotherm and kinetic studies for ammonium ion adsorption by light expanded clay aggregate (LECA)

open access: yesJournal of Saudi Chemical Society, 2016
The possibility of ammonium ion removal from aqueous solution using light expanded clay aggregate (LECA) was investigated in this work. FESEM and XRF analyses are used to determine the sorbent characterization. The influences of some effective parameters

Fibroblast Transcriptomics in Molecular Diagnostics of a Comprehensive Dystonia Cohort

open access: yesAnnals of Neurology, EarlyView.
Objective Genomic sequencing leaves >50% of dystonia‐affected individuals without a diagnosis. Where DNA‐oriented approaches remain insufficient, integrating multiomics is essential to advance genome interpretation. Herein, we incorporated RNA sequencing (RNA‐seq) data from 167 patients with dystonia across a range of ages and presentations. Methods We

Production of Heat-Insulating Concrete Hollow Block

open access: yesJournal of Engineering and Sustainable Development
Hollow concrete blocks are primarily used in residential buildings, factories, and multi-storied construction. The main goal is to produce a new insulation block from lightweight concrete by mixing light expanded clay aggregate (LECA) at a specified ...

Comparative Study on Light Weight Concrete by using Light Expanded Clay Aggregate and Pumice Stone [PDF]

open access: yesE3S Web of Conferences
In order to increase compressive strength while decreasing thickness and weight, lightweight concrete is crucial to the construction of concrete. By including clay and pumice into the composite, the study focuses on analyzing the qualities of the ...
