Microfluidic or microchannel artificial lungs promise to enable a new class of truly portable, therapeutic artificial lungs through feature sizes and blood channel designs that closely mimic those found in their natural counterpart. These new artificial lungs could potentially: 1) have surface areas and priming volume…
In this review, we highlight the recent research efforts towards understanding the defect chemistry of titanium dioxide. Particular attention is paid to the synthesis of self-modified TiO 2 materials with Ti 3+ /oxygen vacancies and the favorable effects of these defects on the properties and applications of the obtai…
A simple, environmental benign, time and cost-efficient green approach has been proposed for the reduction of graphene oxide (GO) and the synthesis of reduced GO (rGO)/mono and bimetallic composites using Azadirachta indica extract. The high crystallinity and face-centred-cubic structure of monometallic silver (Ag) an…
The electrochemical performance of Li 1.2 Mn 0.54 Ni 0.13 Co 0.13 O 2 is improved by partially replacing Li with Mg.
We isolate the most computationally expensive steps of a robust nuclear reactor core Monte Carlo particle transport simulation. The hot kernel is then abstracted into a simplified proxy application, designed to mimic the key performance characteristics of the full application. A series of performance verification test…
Nature has had millions of years to optimize photonic crystals - an endeavour mankind only really began in the 1980s. Often, we attempt to mimic and expand upon nature's designs in creating photonic structures that meet our technology-driven needs. While this strategy can be fruitful in fabricating novel architectures…
Our designed chemosensor, rhodamine-HBT-dyad (RHD), selectively detects two biologically important ions (Al 3+ and Zn 2+ ) at two different wavelengths (red and green, respectively) through FRET and ESIPT in vitro and in vivo .
Flaws, imperfections and cracks are ubiquitous in material systems and are commonly the catalysts of catastrophic material failure. As stresses and strains tend to concentrate around cracks and imperfections, structures tend to fail far before large regions of material have ever been subjected to significant loading.…
We report on our investigations on charge transport and recombination in TiO(2)-based mesoporous solar cells using PbI(2) and various perovskite compositions, including CH(3)NH(3)PbI(3), CH(3)NH(3)PbI(2)Br, CH(3)NH(3)PbIBr(2), and CH(3)NH(3)PbBr(3). The mesoporous TiO(2) film is about 650 nm thick. Electron microscopy…
A host-guest inclusion complex was constructed from a water-soluble pillar[6]arene and a tetraphenylethene derivative in water and it exhibited strong fluorescence in dilute solution.
Germanium is a promising high-capacity anode material for lithium ion batteries, but still suffers from poor cyclability due to its huge volume variation during the Li-Ge alloy/dealloy process. Here we rationally designed a flexible and self-supported electrode consisting of Ge nanoparticles encapsulated in carbon nan…
A redox-flow-battery cell design with multiple ion-exchange membranes is provided to enable combinations of any redox pairs and supporting electrolytes.
PURPOSE: Vitamin D, a liposoluble vitamin has many benefits on health. Encapsulation of bioactives in lipid-based carrier systems like nanoliposomes preserves their native properties against oxidation over time along with providing its stable aqueous dispersion. METHODS: In the current study, vitamin D3 nanoliposomes…
Energetic ionic liquids (EILs) are a subset of the rapidly growing field of ionic liquid research.
Lithium–manganese-rich layered oxides are of great importance as cathode materials for rechargeable lithium batteries. In this article, Li1.2Mn0.567Ni0.167Co0.066O2 is prepared by a co-precipitation method, and the delaminated MnO2 nanosheets with different amounts, 1 wt%, 3 wt% and 5 wt%, are introduced for coating t…
This report presents a process to fabricate perovskite hybrid solar cells in an environmentally responsible fashion by recycling lead materials from spent car batteries.
Herein, we report the stabilization of silver and gold nanoparticles (Ag/Au NPs) on graphene oxide (GO) functionalized with PAMAM dendrimers. The grafting of the PAMAM dendrimers on GO has been investigated using TGA and Raman spectral studies and the stabilization of the Ag/Au NPs on the dendritic structures has been…
Pavement roughness is an expression of the irregularities in a pavement surface that adversely affect the ride quality of a vehicle. Roughness also affects vehicle delay costs, fuel consumption, tires, and maintenance costs. Roughness is predominantly characterized by the international roughness index (IRI), which is…
A highly stable MTP catalyst, boron-modified hierarchical nanocrystalline ZSM-5 zeolite, has been synthesized by a facile salt-aided seed-induced route. It exhibits a long lifetime (about 725 h) even at a high WHSV (4.0 h −1 ).
Poly(quinoxaline-2,3-diyl)s containing (S)-2-methylbutoxy side chains were found to exhibit blue circularly polarized luminescence (CPL). The handedness of the CPL could be switched by a solvent-dependent helix inversion of the polymer backbone between chloroform (M-helical structure) and 1,1,1-trichloroethane (P-heli…
