The poor survival rate of transplanted stem cells in ischemic myocardium has limited their therapeutic efficacy. Curcumin has potent antioxidant property. This study investigates whether prior curcumin treatment protects stem cells from oxidative stress injury and improves myocardial recovery following cells transplan…
Single crystals of 0.01 and 0.02 mol% crystal violet dye doped triglycine sulfate (NH2CH2COOH)3·H2SO4 (TGS) have been grown by a slow evaporation technique. Enhanced dielectric, optical, thermal and mechanical properties have been achieved by dye doping. Monoclinic structures showing particular coloring patterns and m…
Based on a model study, a new bis-cyclic monomer bearing a Diels–Alder adduct was synthesized. This monomer was polymerized with a diamine to yield a thermoresponsive polyhydroxyurethane (PHU). This PHU is remendable at around 100 °C by retro Diels–Alder reaction.
ZnFe 2 O 4 nano-flake thin films prepared using a mechanochemical approach for supercapacitor applications showing excellent specific capacitance, stability, energy and power density.
Ascorbic acid (AA), a potent antioxidant readily scavenging reactive species, is a crucial micronutrient involved in many biochemical processes. Here, we have developed a cobalt oxyhydroxide (CoOOH)-modified upconversion nanosystem for fluorescence sensing of AA activity in human plasma. The nanosystem consists of upc…
Thiadiazolo[3,4- c ]pyridine and selenadiazolo[3,4- c ]pyridine were employed as novel acceptors for rational design of donor-acceptor-type systems, yielding neutral green and near-infrared electrochromic polymers.
Melanoma (MEL) is a less common type of skin cancer, but it is more aggressive with a high mortality rate. The World Cancer Research Fund International (GLOBOCAN 2012) estimates that there were 230,000 new cases of MEL in the world in 2012. Conventional MEL treatment includes surgery and chemotherapy, but many of the…
Spatiotemporal dynamics of excitons in monolayer and bulk WS2 at room temperature is studied by transient absorption microscopy in the reflection geometry. Excitons are formed from photocarriers injected by a tightly focused 390 nm pump pulse, and monitored by detecting different reflection of a time-delayed and spati…
Theranostics is defined as the combination of therapeutic and diagnostic capabilities in the same agent. Nanotechnology is emerging as an efficient platform for theranostics, since nanoparticle-based contrast agents are powerful tools for enhancing in vivo imaging, while therapeutic nanoparticles may overcome several…
A flexible UV photodetector was fabricated based on highly crystalline MoO 3 nanosheets. The photodetector exhibits high UV spectral selectivity, excellent stability, fast response speed and is able to bear significant external mechanical forces.
With a band gap of 2.28 eV, In2S3 is an excellent candidate for visible-light sensitive photodetectors. By growing single-crystalline In2S3 nanowires via a simple CVD method, we report the fabrication of high-performance single-crystal In2S3 nanowire-based flexible photodetectors. The as-fabricated flexible photodetec…
We report here a zwitterionic copolymer based non-covalently cross-linked hydrogel with intrinsic self-healing nature for potential use in enhanced oil recovery.
An impressive oxygen permeability and good structural stability are achieved by partially replacing Fe with In at the B-site of BaFeO 3−δ oxides.
In this work, few layer graphene quantum dots (GQDs) with a size of 3-5 nm are purposely treated with highly concentrated aqueous NaBH4 solutions to obtain the reduced graphene quantum dots (rGQDs). Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy demonstra…
Structure refinement for Aurivillius ferroelectric Na 0.5 Nd 0.5 Bi 4 Ti 4 O 15 and evolutions in T c , P r and E c with the increasing x value in Na 0.5 Nd x Bi 4.5−x Ti 4 O 15 .
With their high surface area, large amount of nitrogen functionalities and high basicity, covalent triazine framework-supported Pd nanoparticles showed a markedly improved activity in the hydrogenation of N-heterocycles compared to the active carbon-supported catalyst.
In this study, a large-area reduced graphene oxide (rGO)/poly(vinyl alcohol) (PVA) film with excellent microwave absorption properties in the range of 2–18 GHz has been prepared by a simple solution processing method.
Operation of a Ni-YSZ electrode supported Solid Oxide Cell (SOC) was studied in both fuel cell mode (FC-mode) and electrolysis cell mode (EC-mode) in mixtures of H2O/H2, CO2/CO, H2O/H2O/CO2/CO at 750 °C, 800 °C and 850 °C. Although the SOCs are reversible, the polarisation characterisation shows that the kinetics for…
A simple, one-step facile approach (precipitation technique) was employed to prepare manganese molybdate (α-MnMoO4). The obtained powder was characterized by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR) and scanning electron microscopy (SEM) for analyzing structural, functional group and mo…
Copper sulfide (CuS) nanorods were synthesized and used as peroxidase mimics for the colorimetric detection of H 2 O 2 .
