A light-emitting OFET with pronounced ambipolar current characteristic has been prepared by co-evaporation of α-quinquethiophene (α-5T) as hole-transport material and ditridecyl-perylene-tetracarboxylic diimide (P13) as electron-transport material.The light intensity is controlled by both the drain-source voltage V DS…
A solid-state methane gas sensor based on PbS colloidal nanocrystals has been fabricated and tested for the first time. PbS nanoparticles have been synthesized during an all-chemical process and its X-ray diffraction (XRD) pattern has been analyzed to verify the quality and estimate the particle size of produced nano-…
This review focuses on recent progress in noncomputational methods to introduce catalytic function into proteins, peptides, and peptide assemblies. We discuss various approaches to creating catalytic activity and classification of noncomputational methods into rational and combinatorial classes. The section on rationa…
One of the major challenges in current cancer therapy is to maximize therapeutic effect and evaluate tumor progression under the scheduled treatment protocol. To address these challenges, we synthesized the cytotoxic peptide (KLAKLAK)2 (named KLAK) conjugated amphiphilic poly(β-thioester)s copolymers (H-P-K) composed…
A series of copper catalysts with a core–shell or tubular structure containing various contents of Cu, Cu 2 O, and CuO were prepared via controlled oxidation of Cu nanowires (NWs) and used in the synthesis of dimethyldichlorosilane (M2) via the Rochow reaction. The Cu NWs were prepared from copper (II) nitrate using a…
Currently, most efficient perovskite solar cells (PVKSCs) with a p-i-n structure require simultaneously electron transport layers (ETLs) and hole transport layers (HTLs) to help collecting photogenerated electrons and holes for obtaining high performance. ETL free planar PVKSC is a relatively new and simple structured…
Li‐ion‐conducting solid electrolytes can simultaneously overcome two grand challenges for Li‐ion batteries: the severe safety concerns that limit the large‐scale application and the poor electrolyte stability that forbids the use of high‐voltage cathodes. Nevertheless, the ionic conductivity of solid electrolytes is t…
BACKGROUND: There is a significant need for soft-tissue replacements in the field of reconstructive surgery. Decellularized adipose tissues were heparin crosslinked and loaded with basic fibroblast growth factor (bFGF). This injectable system was evaluated for its adipogenic and angiogenic capabilities for in vivo adi…
Recently, graphene and graphene-related materials have attracted a great deal of attention due their unique physical, chemical, and biocompatibility properties and to their applications in biotechnology and medicine. However, the reports on the potential toxicity of graphene oxide (GO) in biological systems are very f…
Vapor‐based deposition technique is considered as a promising approach for preparing a high‐quality and uniform perovskite thin film. With evolution from coevaporation deposition to a low‐pressure vapor‐assisted solution process, both energy budget and reaction yield for perovskite film fabrications are improved. In t…
l-Amino acid deaminase from Proteus myxofaciens (PmaLAAD) is a membrane flavoenzyme that catalyzes the deamination of neutral and aromatic l-amino acids into α-keto acids and ammonia. PmaLAAD does not use dioxygen to re-oxidize reduced FADH2 and thus does not produce hydrogen peroxide; instead, it uses a cytochrome b-…
Auxetic composites have attracted considerable attention in recent years and have demonstrated a high potential of applications in different areas due to their wonderful properties as compared to non‐auxetic composites. In this study, a three‐dimensional (3D) auxetic textile structure previously developed was used as…
The release of radionuclides from spent fuel in a geological disposal facility is controlled by the surface mediated dissolution of UO2 in groundwater. In this study we investigate the influence of reactive surface sites on the dissolution of a synthesized CeO2 analogue for UO2 fuel. Dissolution was performed on the f…
We prepared CuInSe 2 and Cu-poor Cu–In–Se (CIS) phases such as CuIn 3 Se 5 and CuIn 5 Se 8 in the composition of (1 − x )Cu 2 Se–( x )In 2 Se 3 with 0.5 ≤ x ≤ 1.0. The crystal structure of the sample changed from chalcopyrite-type CuInSe 2 to hexagonal CuIn 5 Se 8 through stannite-type CuIn 3 Se 5 with increasing x (d…
In the present study Terminalia chebula was used as an eco-friendly natural colorant for sustainable textile coloration of woolen yarn with primary emphasis on thermodynamic and kinetic adsorption aspects of dyeing processes. Polyphenols and ellagitannins are the main coloring components of the dye extract. Assessment…
In 2012, Defence Research and Development Canada, in partnership with a number of other Canadian and International organizations, led a series of three field trials designed to simulate a Radiological Dispersal Device (RDD). These trials, known as the Full-Scale RDD (FSRDD) Field Trials, involved the explosive dispers…
In this work, direct exciton-plasmon interactions (EPI) between CdS quantum dots (QDs) and Ag nanoparticles (NPs) were invoked ingeniously by catalytic Ag deposition on Au NPs for the stimulation of high efficient damping effect toward the excitonic responses in CdS QDs, on the basis of which a novel photoelectrochemi…
A lightweight, flexible, cost-effective, and robust, single-electrode-based Smart Seat-Triboelectric Nanogenerator (SS-TENG) is introduced as a promising eco-friendly approach for harvesting energy from the living environment, for use in integrated self-powered systems. An effective method for harvesting biomechanical…
Gold nanoparticles have recently gained attention as heterogeneous catalysts in a variety of industrially relevant processes. The catalytic activity of the particles is directly related to the available surface area, which increases with decreasing particle size. However, their stability in solution decreases along wi…
Suspension-feeding fishes such as goldfish and whale sharks retain prey without clogging their oral filters, whereas clogging is a major expense in industrial crossflow filtration of beer, dairy foods and biotechnology products. Fishes' abilities to retain particles that are smaller than the pore size of the gill-rake…
