Ranking PVC Roofing Membranes Using Thermal Analysis

open access: yesJournal of Materials in Civil Engineering, 1993
The effects of accelerated heat aging on three polyvinyl chloride (PVC) roofing membranes was determined using thermogravimetry (TG), dynamic mechanical thermal analysis (DMA), and tensile testing. The heat aging was done at 100°C and 130°C. In general, it was found that the degradation of the reinforced PVC roofing membranes was proportional to the ...

In Situ Photopolymerization of Smectic B Liquid‐Crystalline Electrolytes from Mesogenic Phosphate–Diacrylate/Ionic Liquid Complexes for High‐Performance Soft Ionic Actuators

open access: yesAdvanced Robotics Research, EarlyView.
A flexible liquid‐crystalline electrolyte membrane via in situ photopolymerization of a phosphate‐functionalized mesogen, ionic liquid, and diacrylate monomer is developed. The resulting smectic B (SmB)‐phase structure enables 2D ion transport with high conductivity (10−4 S cm−1).

Nitrate And Bicarbonate Selective Chemfets [PDF]

open access: yes, 1995
The development of durable anion selective CHEMFET micro sensors is described. Selectivity in these sensors is either obtained from differences in hydration energy of the anions (the Hlofmeister series, giving nitrate selectivity) or by introduction of a

Tomato spotted wilt virus glycoproteins induce the formation of endoplasmic reticulum- and Golgi-derived pleomorphic membrane structures in plant cells [PDF]

open access: yes, 2008
Tomato spotted wilt virus (TSWV) particles are spherical and enveloped, an uncommon feature among plant infecting viruses. Previous studies have shown that virus particle formation involves the enwrapment of ribonucleoproteins with viral glycoprotein ...

An Energy Autonomous Microneedle Array‐Based Sensing System for Continuous Biomarker Monitoring

open access: yesAdvanced Science, EarlyView.
This work presents an innovative self‐powered wearable biosensor system for real‐time monitoring of multiple biomarkers in interstitial fluid. The device integrates stainless steel‐based minimally invasive microneedles with ion‐selective membranes, enabling simultaneous Na+, K+, Ca2+, pH, and glucose detection.
