Intelligent Polymer Electrolytes for Next‐Generation Zinc‐Based Energy Storage Devices

open access: yesAdvanced Science, EarlyView.
Intelligent polymer electrolytes are organized into a three‐level hierarchy that advances zinc‐based energy storage from passive ion conduction toward active, adaptive, and intelligent operation. Molecular regulation of Zn+ coordination, water activity, desolvation, ion flux, and interfaces underpins adaptive self‐healing, anti‐freezing, adhesion, and ...

Evaluation of the chemical and thermo-physical properties of locally aggregated kaolin-based refractory materials

open access: yesJournal of Mechanical Engineering and Sciences, 2019
There is a continuous demand for refractory materials to meet the increasing expansion of industries and plants. Local clay materials are being explored to augment the inadequate supply of refractory materials.

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 ...

Electrokinetic Stabilization of Formation Fines Using Surface Modified Polymer Silica Nanocomposites During Low Salinity Water Flooding for Enhanced Oil Recovery

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Fines migration induced by low salinity water flooding severely impairs reservoir permeability and injectivity presenting a critical challenge in enhanced oil recovery. This study aims to synthesize and evaluate a surface‐modified polymer‐silica nanocomposite to mitigate clay mobilization and preserve the hydrodynamic capacity of porous media.

Concentration‐Dependent Lamellar Organization and Structure–Property Relationships in Melt‐Processed EVA/Cloisite 20A Nanocomposites

open access: yesJournal of Applied Polymer Science, EarlyView.
Cloisite 20A content tunes the structural and mechanical response of melt‐processed ethylene‐vinyl acetate (EVA) nanocomposites. Expanded basal spacings at 5.0 and 7.5 wt% clay are consistent with polymer‐chain intercalation within ordered clay domains.

Sorption behavior of pomegranate polyphenols on surfactant-modified clays in aqueous solution

open access: yesScientific African
Purpose: Phenols are defined as primary pollutants. They can be present at high concentrations in the bulk effluents generated by the agro-food industries which can be toxic and have an impact on microbial processing in wastewater treatment plants.

Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

open access: yesThe Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Bite force estimates and morphological correlations of jaw muscles in parrots

open access: yesThe Anatomical Record, EarlyView.
Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Dissecting the dissection laboratory: Elements for designing a human anatomy laboratory

open access: yesAnatomical Sciences Education, EarlyView.
Abstract The human anatomy dissection laboratory is a critical component of anatomical and medical education. Development, maintenance, and stocking of these laboratory spaces have unique demands, with all of the challenges in running a laboratory with Biosafety Laboratory Level 2 (BSL‐2) classification, housing a large volume of tissues saturated with
