Hydrocarbon separation relies on energy-intensive distillation. Membrane technology can offer an energy-efficient alternative but requires selective differentiation of crude oil molecules with rapid liquid transport. We synthesized multiblock oligomer amines, which comprised a central amine segment two hydrophobic blocks, and used them to fabricate polyamide nanofilms by interfacial polymerization from self-assembled vesicles. These provide transport liquids more than 100 times faster that...
The design of materials and their manufacture into membranes that can handle industrial conditions separate complex nonaqueous mixtures are challenging. We report a versatile strategy to fabricate polytriazole with 10-nanometer-thin selective layers containing subnanometer channels for the separation hydrocarbons. process involves use classical nonsolvent-induced phase method thermal cross-linking. membrane selectivity be tuned lower end typical nanofiltration range (200 1000 gram mole −1 )....
Alzheimer's disease (AD) is a neurodegenerative disorder associated with severe loss in thinking, learning, and memory functions of the brain. To date, no specific treatment has been proven to cure AD, early diagnosis being vital for mitigating symptoms. A common pathological change found AD-affected brains accumulation protein named amyloid-β (Aβ) into plaques. In this work, we developed micron-scale organic electrochemical transistor (OECT) integrated microfluidic platform label-free...
Although numerous polymer-based composites exhibit excellent dielectric permittivity, their performance in various applications is severely hampered by high loss induced interfacial space charging and a leakage current. Herein, we demonstrate that embedding molten salt etched MXene into poly(vinylidene fluoride–trifluoroethylene–chlorofluoroethylene) (P(VDF–TrFE–CFE))/poly(methyl methacrylate) (PMMA) hybrid matrix induces strong interactions, forming close-packed inner polymer layer leading...
Polysiloxanes were modified by (co-)hydrosilylation with γ-cyanopropyl and hexyl groups, to finely tune their composition properties, especially dielectric permittivity, as a way towards active components in elastomer transducers. Un-modified Si–H groups can be further used obtain cross-linked thin films.
Membrane-based technologies have a tremendous role in water purification and desalination. Inspired by biological proteins, artificial channels (AWCs) been proposed to overcome the permeability/selectivity trade-off of desalination processes. Promising strategies exploiting AWC with angstrom-scale selectivity revealed their impressive performances when embedded bilayer membranes. Herein, we demonstrate that self-assembled imidazole-quartet (I-quartet) AWCs are macroscopically incorporated...
A novel bio-based flexible epoxy resin from castor oil maleate and diglycidyl ether of bisphenol was synthesized its thermal electrical properties were investigated.
Organic mixed ionic-electronic conductors (OMIECs) are materials that can be used to build bio-inspired electronic devices as they emulate ion-based cellular communication through doping with aqueous ionic charges. The integration of charge photogeneration and electrochemical processes in the polymer film enables optoelectronic applications involve synaptic transistors. However, no OMIEC has yet been implemented create a miniaturized photoactive platform capable perceiving processing...
Dielectric and conduction properties of polyimides were evaluated on the basis dielectric constant, loss, electric modulus AC conductivity, their variation with frequency temperature. Polyimide films exhibited good insulating constants values in range 2.78-3.48 loss comprised between 0.01 0.03 at 1Hz room
We report a simple method for rapid replication of hierarchical, isotropic porous materials that mimic complex living structures.
A trend line method to facilitate the design of new block copolymer membranes, based on self-assembly and non-solvent induced phase separation is proposed.
This work aims to elucidate the particle growth mechanism during agglomeration using a bottom-spray fluidized bed process produce technical catalysts. The influences of fundamental operating parameters granulation were investigated through (i) experiments in newly designed small-scale reactor, (ii) morphological characterization catalytic particles produced, (iii) dimensionless number analysis, and (iv) principal component analysis. These results could define stage as dust formation, seed...
