Abstract For the proper design and evaluation of next‐generation lithium‐ion batteries, different physical‐chemical scales have to be considered. Taking into account electrochemical principles methods that govern processes occurring in battery, present review describes main theoretical thermal models allow simulation performance including materials components (electrodes separators) battery geometries. As separator plays an essential role safety recent work for this component are shown, with...

Contrary to conventional ATRP, aqueous A(R)GET-ATRP at ambient temperature without deoxygenating reaction solutions is an extremely facile method create polymer brushes. Using these techniques, thick poly[2-(dimethylamino)ethyl methacrylate] brushes can be prepared (∼700 nm), or low chemical-content, consisting of 99% v/v water. Based on we have also developed easy and inexpensive method, referred as "paint on"-ATRP, that directly pastes onto various large-scale real-life substrates open the...

Poly(propylene oxide)–poly(ethylene oxide)–poly(propylene oxide) (PPO–PEO–PPO) block copolymers (BCPs) with cross-linkable end groups were synthesized, blended an ionic liquid (IL) diluent, and cross-linked to form polymer gel electrolytes. The IL prevented crystallization of PEO at high concentrations, enabling fast ion transport. In addition, the was selective for block, inducing strong microphase separation in what are otherwise disordered or weakly ordered BCP melts. Cross-linking BCPs...

A fluorinated and hydrophobic ionic liquid (IL), 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide, effectively served as an advantageous lubricating for the preparation of physically chemically stable omniphobic surfaces based on slippery liquid-infused porous surfaces. Here, we used particulate microstructures supports, prepared by chemical vapor deposition 1,3,5,7-tetramethylcyclotetrasiloxane subsequent surface modification with (3-aminopropyl)triethoxysilane. Confirmed SEM...

The dynamic dewettability of a smooth alkyl-terminated sol-gel hybrid film surface against 17 probe liquids (polar and nonpolar, with high low tensions) was systematically investigated using contact angle (CA) hysteresis substrate tilt (TA) measurements, in terms their physicochemical properties such as tension, molecular weight/volume, dielectric constant, density, viscosity. We found that the markedly depended not on tensions but constants liquids, displaying lower resistance to liquid...

Well-ordered block copolymer (BCP) morphologies are obtained by blending PEO−PPO−PEO triblock surfactants with the room temperature ionic liquid (IL) 1-butyl-3-methylimidazolium hexafluorophosphate. The selective association of IL PEO blocks increases segregation strength raising effective interaction parameter between and PPO blocks. Therefore, copolymer/IL blends form well-ordered microdomains in melt, whereas neat copolymers phase mixed. is shown to interact chains a depression melting...

This paper describes the processing of silver nanoparticle doped poly(vinylidene fluoride). The effect dopant concentration on alpha- to beta-phase transformation polymer as well in morphological, thermal, optical and dielectric properties nanocomposites was investigated. Spherical nanoparticles were incorporated into fluoride) polymeric matrix by solvent casting method, with different Ag concentrations. Well-dispersed act nucleation centers, increasing degree crystallinity nanocomposites....

This work provides a review on theoretical simulation and experimental results in separator membranes for zinc–manganese oxide batteries, where this battery system has gained interest as an alternative to lithium-ion batteries.

This study is part of the research project Dep-Project: Design and Embodiment Wearable Prostheses, funded by Foundation for Science Technology (FCT), whose main objective development wearable myoelectric prostheses upper limbs, which are economically accessible, socially accepted, personalizable. In this context, need arose to create an online platform with intuitive interface, would facilitate access persons limb amputation information about prosthetics allow them personalize their...

A multitude of factors, including accidents, chronic illnesses, and conflicts, contribute to rising global amputation rates. The World Health Organization (WHO) estimates that 57.7 million people lived with traumatic limb amputations in 2017, many lacking access affordable prostheses. This study presents a preliminary framework for low-cost, electromyography (EMG)-controlled upper prosthesis, integrating 3D printing EMG sensors enhance accessibility functionality. Surface electrodes capture...

This study analyzed the physical and bacterial composition of canals on Muralla Street in Intramuros, Manila. Canals samples were collected from five schools: Colegio de San Juan Letran (CSJL), Lyceum Philippines University (LPU), Mapua (MU), Pamantasan ng Lungsod Maynila (PLM), Manila High School (MHS). Physical properties following APHA 1985 methods used Okechukwu Obire's study. Bacterial enumeration serial dilution spread plate techniques to obtain total viable count (TVC). Analysis...

Abstract Phase transitions of polymeric materials are accompanied by changes in density as a function temperature. Being able to measure these systems one, two or three dimensions on the nanoscopic length‐scale is challenge, but it would provide simple route assess phase nanoscopically confined systems. It shown that measurement dielectric permittivity high frequency limit (in spectral regions not affected dispersions) offers an effective and very sensitive means fluctuations, hence...
