Due to the reduced ability of most harmed tissues to self-regenerate, new strategies are being developed in order to promote self-repair assisted or not by biomaterials, among these tissue engineering (TE). Human adipose-derived mesenchymal stem cells (hASCs) currently represent a promising tool for tissue reconstruct…
The magnetic properties of samples of NiO nanoparticles with average sizes of 23, 8.5, and 4.5 nm were investigated. Using the magnetization curves measured in strong (up to 250 kOe) pulsed magnetic fields, the contributions of the free spin and ferromagnetic subsystems were extracted. It has been found that the ferro…
Background: Synthesis of metal oxides nanoparticles with specific morphology and size has become the subject of many experimental protocols. Biosynthesis of the nanoparticles using plants is more preferable than physical and chemical methods because of its environmental friendliness. Objective: The purpose of this stu…
Accurate models for condensation heat transfer are necessary to improve condenser design. Drop-size distribution is an important aspect of heat transfer modeling that is difficult to measure for small drop sizes. The present work uses a numerical simulation of condensation which incorporates the possibility of coalesc…
Abstract The unsaturated bicyclic acetal levoglucosenyl methyl ether was readily obtained from sustainable feedstock (cellulose) and polymerized by cationic ring‐opening polymerization to produce a semicrystalline thermoplastic unsaturated polyacetal with relatively high apparent molar mass (up to ca. 36 kg mol−1) and…
Heteroatom doping and a porous structure are two significant factors that improve the capacitance performance of carbon‐based electrodes, but there are often one‐sided considerations between them. Herein, effective B, N co‐doping and trimodal‐porous structure from the carbonization of sustainable natural wood are obta…
Abstract Pure organic, amorphous room‐temperature phosphorescent (RTP) materials have aroused great attention because of their easy preparation and wide applications. Herein, several metal‐free, amorphous, lactam phosphorescent copolymers are prepared. Copolymers of N‐vinylpyrrolidone (NVP) and N‐vinylcaprolactam (NVC…
Zeolitic Imidazolate Framework (ZIF-67) was prepared in two different solvents-water and methanol. Nanoporous carbon was derived from ZIF-67 via pyrolysis in an inert atmosphere. Anion exchange step of sulfidation on the synthesized material has a great influence on the structure and properties. Structural morphology…
Meta-periodicity beyond intrinsic atomic and molecular order, such as metacrystalline and quasicrystalline lattices, exists in solids, but is usually elusive in lyotropic liquid crystals for its energetic instability. The stable meta-periodicity in lyotropic liquid crystals in the absence of external stimuli remains u…
Sensitive and selective assays are demanded for quantitation of new psychoactive substances such as 4-chloroethcathinone that is a π-conjugated keto compound. Carbon dots (C-dots) prepared from L-arginine through a hydrothermal route have been used for quantitation of 4-chloroethcathinone in aqueous solution and on C-…
Geometric structures are commonly encountered in natural and designed systems. However, the bottom-up fabrication of regular geometric assemblies with precise dimensional control, especially from soft materials, poses an outstanding challenge in contemporary materials science and chemistry. Herein, we present a genera…
This work reviews the recent progress made in last decade in understanding the role of dispersion of nanoparticles and quantum dots into host nematic liquid crystals. There are two important ingredients of this work: Even a minute concentration of these non-mesogenic materials in host matrix can have reflective impact…
Abstract Since its discovery nearly a century ago, antibiotics has been one of the most effective methods in treating infectious diseases and limiting pathogen spread. However, pathogens often build up antibiotic resistance over time, leading to serious failure of the treatment. Silver nanoparticle (AgNP) is an appeal…
We investigate the performance and reliability characteristics of Cu interconnects with Ta-based barrier layers and Co wetting layers at 7nm node dimensions with a focus on the impacts of reducing the Co thickness from 30Å down to 10Å. We demonstrate that while reducing Co liner thickness significantly reduces RC dela…
Here, we describe a redox-responsive Pickering emulsion stabilized by silica nanoparticles and a ferrocene surfactant (FcCOC 10 N) at a concentration as low as 0.01 mM (≈0.005 cmc). The emulsions are stable and resistant to coalescence for more than one month. The ferrocene group in the structure of FcCOC 10 N can be…
Abstract Directional transportation of liquid droplets plays a significant role in various processes including anti‐fogging, anti‐icing, and materials transportation. Diverse strategies have been developed to achieve lateral bouncing of impacting droplets. However, due to the complexity of the interactions on the inte…
WSe 2 is a layered ambipolar semiconductor enabling hole and electron transport, which renders it a suitable active component for logic circuitry. However, solid-state devices based on single- and bilayer WSe 2 typically exhibit unipolar transport and poor electrical performance when conventional SiO 2 dielectric and…
Zein, corn starch (CS), and orange-peel oil (OPO) extracted from orange peels were used to prepare novel corn starch/orange-peel oil/zein nanocapsules (OZN) bio-active food packaging materials. The results showed that the OZN were round, smooth and in compact morphology with an average diameter of 102.7 ± 10.5 nm from…
Resolving the dynamics of photoexcited d-holes in metallic nanostructures is one step in the rational design of plasmonic photocatalysis. Here, we track the creation and relaxation of charge carriers in catalytically important plasmonic copper nanocubes using single-particle spectroscopy. We show that interband transi…
In this Letter, we report on the interaction of Nb 2 SnC ternary transition metal carbide (MAX phase) with Li ions. Because of the presence of Sn layers, which can undergo alloying reaction with Li, this material may be promising for energy storage. Contrary to most electrodes, the performance of this material improve…
