Electro-expulsive separation system [PDF]

open access: yes, 1987
An electro-expulsive system has one or more overlapped conductors, each comprising a flexible ribbon conductor, which is folded back on itself. The conductors are embedded in an elastomeric material.

Construction of a CO2‐Fixing Compartment Using a Shape‐Transforming DNA Scaffold

open access: yesChemistry – A European Journal, EarlyView.
A shape‐transforming DNA scaffold encapsulates RuBisCO within a controllable, self‐contacting compartment that mimics the carboxysome. The scaffold switches between open and closed states, enabling direct comparison of identical enzyme populations in different microenvironments.

On the Role of Linker Fluorination in the Adsorption‐Induced Structural Response of CeIV‐Based Metal‐Organic Frameworks

open access: yesChemistry – A European Journal, EarlyView.
The effect of the degree of fluorination of the organic linker on the adsorption behavior of MIL‐140A(Ce) is systematically investigated with a combination of experimental techniques. Cooperative adsorption is switched off in less fluorinated frameworks, as a result of reduced steric hindrance around the adsorption sites.

Toward Safer and Sustainable Lithium Metal Batteries: Fluorine‐Free Solid Polymer Electrolytes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An analysis to assess the impact of fluorine in polymer electrolyte‐based lithium metal batteries has been conducted. It has been demonstrated that fluorine‐free LiTIM salt delivers a electrochemical performance similar to that of its fluorinated analogue salts, given the complete lithium dissociation in coordination with PEO and the restricted anion ...

Recent Advances in Pickering Emulsion Templated Phase Change Material Microcapsules: Design, Fabrication, and Multifunctional Applications

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fabrication process of phase change microcapsules using a Pickering emulsion template method and their subsequent applications. The increasing demand for efficient thermal energy storage systems has driven the development of phase change material microcapsules (PCMMs), which provide high energy‐storage density, reversible phase change, and reduced ...

Leakage performance of a novel turbomachinery shaft seal [PDF]

open access: yes, 2009
Advanced sealing systems are needed to control parasitic leakage flows to achieve high turbine engine efficiency and low emissions. Typical extreme turbomachinery engine operating conditions when combined rotor excursions do not lend simple sealing ...

Fractionation of Milligram Quantities of Gadolinium and Terbium Ions by Annular Free‐Flow Isotachophoresis

open access: yesELECTROPHORESIS, EarlyView.
ABSTRACT The fractionation of milligram quantities of gadolinium (Gd) and terbium (Tb) ions is demonstrated using annular free‐flow isotachophoresis (ITP) with ammonium as the leading ion and hydronium as the terminating ion, and α‐hydroxyisobutyric acid (HIBA) and acetate as lanthanide complexing ligands.

Mutation type‐specific transcriptomic signatures and readthrough therapy rescue in SMC1A‐related developmental and epileptic encephalopathy

open access: yesEpilepsia, EarlyView.
Abstract Objective This study was undertaken to investigate the molecular consequences of pathogenic variants in the SMC1A gene—particularly those associated with developmental and epileptic encephalopathy (DEE85)—and to evaluate the therapeutic potential of ataluren in restoring SMC1A function and mitigating disease‐related transcriptomic and genomic ...
