High-performance metal-semiconductormetal ultraviolet (UV) photodetector was fabricated based on In2O3/TiO2heterostructure. The In2O3/TiO2heterostructure photodetector exhibits the maximum responsivity of 799.5 A/W and Gain of 3541.8 under 280 nm wavelength of illumination at 2 V, which is eight times higher than the…
Lead sulfide quantum dots (QDs) have been widely used for various optoelectronic devices due to their high absorption coefficient and tunable bandgap. However, the low mobility of QD films results in poor charge collection and device performance. By combining QDs with graphene into hybrid graphene/QD photodetectors, p…
Abstract We report an extensive structural characterization of the surface of 1T-PtTe 2 crystals by means of helium atom scattering (HAS) and ultra-high resolution scanning tunnelling microscopy (STM). HAS reveals that this bi-dimensional surface presents a large structural corrugation (∼ ) in direction. The surface l…
Recently, much attention has been paid to semiconductor–metal hybrid nanostructures (HNs) in terms of efficient electron transfer from the semiconductor to the metal and semiconductor–metal HNs are one of the best candidate materials for photovoltaics and photocatalysis. However, the analyses of electron-transfer proc…
β-Cyclodextrine-based polyester was coated on the surface of gadolinium oxide nanoparticles (NPs) and then functionalised with folic acid to produce an efficient pH-sensitive targeted theranostic system (Gd2O3@PCD-FA) for doxorubicin delivery and magnetic resonance imaging (MRI). Gd2O3@PCD-FA was fully characterised b…
A skin structure for thermal protection is one of the most interesting components that needs to be considered in the design of a hypersonic vehicle. The thermal protection structure, if a dense structure is used, is heavy and has a large heat conduction path. Thus, a lightweight, high strength structure is preferable.…
Abstract Carbon-based nano hetero-structures are receiving increasing attention due their ability in multi-synchronous modulation of a range of mechanical and other critically desirable properties. In this paper, the vibration characteristics of two different graphene based heterostructures, graphene-hexagonal boron n…
It is very well known that the incorporation of fillers into polymers increases their viscosity in a molten state; however, results contrary to this have been reported when graphite (Gr), graphite oxide (GrO), and graphene oxide (GO) among other carbonaceous fillers are used. Many authors have justified the reduction…
The critical behavior of Heusler alloy $\mathrm{Co}{}_{2}\mathrm{TiSn}$ is investigated by bulk magnetization study around the paramagnetic to ferromagnetic transition. The precise value of Curie temperature ($T{}_{c}=358\phantom{\rule{4pt}{0ex}}\mathrm{K}$) as well as the critical exponents ($\ensuremath{\beta}=0.527…
Superhydrophobic surfaces show attractive anti-icing properties. However, it remains a challenge for them to achieve icephobicity and ultralow ice adhesion in a humid environment, which is fundamentally attributed to the icing behavior on their hierarchical textures. Here, we address the issue by integrating a superhy…
Reactive oxygen and nitrogen species (RONS) are an important class of oxidative stress mediators which are tightly associated with several diseases. Therefore, it is important to develop an accurate and reliable method for the in situ monitoring of biologically relevant RONS. Fluorescent bioprobes exhibit remarkable s…
The structure of pepsin-solubilized collagen (PSC) obtained from the skin of Lophius litulon was analyzed using the sodium dodecylsulphate polyacrylamide gel electrophoresis (SDS-PAGE), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). SDS-PAGE results showed that PSC from Lophius…
We have implemented both the Dornauf–Heber (D–H) model and a brute force statistical (BFS) model to characterize the quenching by neighboring Er and Yb ions of the green and blue emitting states of Er in β-NaYF 4:Yb,Er@NaYF 4 nanoparticles. Each of these models explicitly considers the radial distribution of Er and Yb…
The binding energies of adsorbates at catalytic surfaces are in general functions of adsorbate coverage, with corresponding consequences for equilibrium surface coverages and reaction rates under relevant conditions. This coverage dependence is commonly incorporated into mean-field microkinetic models by writing adsor…
Phosphate functionalized carbon nanomaterials have attracted significant attention because of their potential applications in energy storage applications. Herein we report a facile one-pot method to prepare water dispersible phosphate functionalized reduced graphene oxide and demonstrate the potential of the novel mat…
The effect of the addition of cellulose nanocrystals (CNCs) on the properties of cement pastes is studied herein. The compressive strength of CNC/cement paste was investigated under the curing conditions defined in this study. Two-dimensional micrographs and pore size distributions were obtained by scanning electron m…
An understanding of the anisotropic growth mechanism of gold nanorods (AuNRs) during colloidal synthesis is critical for controlling the nanocrystal size and shape and thus has implications in tuning the properties for applications in a wide range of research and technology fields. In order to investigate the role of…
Silk nanofibers have been produced and examined in recent years for a range of advanced biomedical and biotechnological applications. Their fabrication involves the canonical approach of dissolving native silk fibers in a highly concentrated (mostly lithium-ion-based) chaotropic salt, followed by spinning fibers from…
Hyper-cross-linked porous polymers (HCPs) are proposed as sorbents for the removal of aromatic volatile pollutants by using toluene as a representative of the BTX family. The hierarchical (micro and meso) porous architecture of the HCPs has been established by N 2 physisorption at 77 K while the toluene adsorption cap…
In this work, fluorescent copper nanoclusters (CuNCs) have been fabricated with ascorbic acid (AA) as reductant and polyvinyl pyrolidone (PVP) as scaffold in aqueous solution for the on-site detection of hypochlorous acid (HClO) with high sensitivity and selectivity. The CuNCs showed a specific fluorescence quenching…
