ions simultaneously by switching unique structural changes between porphyrin, porphodimethene and porphyrinogen along with distinct colour changes which were monitored by UV-Vis-NIR, fluorescence and NMR spectroscopic techniques.
We have developed host–guest fluorescent complexes based on cucurbit[8]uril and a perylenemonoimide for selective and sensitive detection of N-terminal phenylalanine peptides.
Both theoretical calculations and electrochemical measurements suggest the applicability of Cu 2 SnS 3 as an efficient alternative catalyst in DSSCs.
abstract: Stimuli-responsive polymers or so-called “smart polymers” are macromolecules that are sensitive to certain triggers from the external environment, including temperature, light, electrical or magnetic fields, and chemicals. The activated polymers produce observable or detectable micro- or nanoscale changes, s…
The performance of separators of ion-exchange membrane (IEM) and diaphragm types in the zero-gap system of alkaline water electrolysis (AWE) was examined using different sizes of cells (i.e., 20, 100 and 1600 cm 2 ).The optimum KOH concentrations for AWE were found to be ca.15 and 25-30 wt% for IEM and diaphragm, resp…
Osteochondral defect repair poses a significant challenge in its reconstruction as the damage is presented in both articular cartilage and the underlying subchondral bone. Thus we present a osteochondral scaffold for articular cartilage repair.
For understanding the self-assembly behaviours of norbornene-based main-chain polymers depending on side-chain pendants, a series of polynorbornenes containing the programmed dendrons is newly designed and successfully synthesized via ring opening metathesis polymerization.
In this survey, N, La co-doped TiO 2 nanocrystals are synthesized through simple sol–gel method. Results reveal that both elements of N and La are introduced successfully into the structure of TiO 2 and exist as the form of La (Ti–O–La) bonds, N (N–Ti–O) bonds and N (Ti–O–N) bonds by several characterization analysis,…
Efflorescence in geopolymers can be a significant issue as the binder contains much higher soluble alkali metal concentrations than conventional cements. This paper reports the quantification method used to evaluate efflorescence potential on fly ash based geopolymer from the leaching behaviour of alkali metal in the…
Here we demonstrate direct use of sulphate rich seaweed polysaccharides, carrageenans, namely kappa (κ-), iota (ι-) and lambda (λ-) as a source of sulphur and carbon doping in TiO 2 photocatalysts.
Glow discharge plasma would modify the surface hydrophilicity of support; the plasma treated catalysts showed much higher FTS activity.
Novel hypergolic energetic salts containing the (2-methyltetrazol-5-yl)diazotate anion were synthesized and exhibit attractive short ignition delay times with white fuming HNO 3 .
Second harmonic generation of a single irregular-geometry SiC nanoparticle is better than from a single spherical-geometry SiC nanoparticle and bulk SiC because of magnetic resonance enhancement at second harmonic wavelength.
Ischemic diseases are a group of diseases, including ischemic cerebrovascular disease, ischemic cardiomyopathy (ICM), and diabetic foot as well as other diseases which are becoming a leading cause of morbidity and mortality in the whole world. Mesenchymal stem cells (MSCs) have been used to treat a variety of ischemic…
Photographs of the microstructures of PT300-100 and Ortex-560 glass fibers obtained on an electron microscope and three-dimensional patterns of their surfaces obtained on an atomic-force microscope are given. A procedure for the evaluation of the roughness characteristics of glass fibers using an atomic-force microsco…
Amyloids are protein fibrils adopting structure of cross-beta spine exhibiting either pathogenic or functionally significant properties. In prokaryotes, there are several groups of functional amyloids; however, all of them were identified by specialized approaches that do not reveal all cellular amyloids. Here, using…
Experimental and theoretical charge density of piroxicam, saccharin and their 1 : 1 co-crystal have been determined using high-resolution X-ray diffraction, multipole refinement and DFT calculations
Mesoporous anatase titanium dioxide (TiO2) is prepared by an easily up-scalable synthesis protocol, using relatively inexpensive precursors. We demonstrate here that submicronic anatase TiO2 crystals show unexpected performances as electrodes of Na-ion batteries (NaBs). They exhibit highly stable reversible specific c…
The facile synthesis of nanoparticles for precise image control and fast response of chromatic electrophoretic displays (EPDs) is a challenge. Herein, we report a general method to prepare pink, blue, and yellow nanoparticles with low density and a tunable size of 230-310 nm. The monodispersity is down to 0.02 and sur…
Networks-on-Chip (NoCs) have garnered significant interest as communication backbone for multicore processors used across a wide range of fields that demand higher computation capability. Wireless NoCs (WNoCs) by augmenting single hop, long range wireless links with wired interconnects; offer the most promising soluti…
