Microbial cellulose, an exopolysaccharide produced by bacteria, has unique structural and mechanical properties and is highly pure compared to plant cellulose. Present study represents isolation, identification, and screening of cellulose producing bacteria and further process optimization. Isolation of thirty cellulo…
Graphene-ceria (CeO2G) nanocomposites were prepared by using a low-temperature solution process with different weight percentages of graphene, and their electrochemical properties were investigated. Structural properties of the nanocomposites were studied by X-ray diffraction, Raman spectroscopy, and FTIR spectral ana…
Flower-like MgAl layered double hydroxides (MgAl-LDHs) with chloride and carbonate ions as interlayer anions showed excellent adsorption capacities for As( v ) and F − ions under neutral conditions.
The influence of Bi(3+)-doping on the magnetic and Mössbauer properties of cobalt ferrite (CoFe2O4), wherein the Fe(3+) ions are replaced by the Bi(3+) ions to form CoBixFe2-xO4 ferrites, where x = 0.0, 0.05, 0.1, 0.15 or 0.2, has been investigated. The structural and morphological properties of undoped and doped ferr…
A robust and compact freestanding conducting polymer-based electrode material based on nanocellulose coupled polypyrrole@graphene oxide paper is straightforwardly prepared via in situ polymerization for use in high-performance paper-based charge storage devices, exhibiting stable cycling over 16,000 cycles at 5 A g(-1…
The electronic structure, lattice vibrations, and optical, dielectric and thermodynamic properties of BaTiO 3 /CaTiO 3 /SrTiO 3 (BT/CT/ST) ferroelectric superlattices are calculated by using first-principles calculations.
We investigate the photocurrent generation mechanisms at a vertical p-n heterojunction between black phosphorus (BP) and molybdenum disulfide (MoS2) flakes through polarization-, wavelength-, and gate-dependent scanning photocurrent measurements. When incident photon energy is above the direct band gap of MoS2, the ph…
A facile two-step strategy is adopted to construct a free-standing composite paper of MnO 2 nanoflake/polyaniline (PANI) nanorod hybrid nanostructures on reduced graphene oxide (RGO) for flexible supercapacitor electrode application.
Nanosheet materials such as graphene, boron nitride and transition metal dichalcogenides have gathered attention in recent years thanks to their properties and promises for future technology, energy generation and post-CMOS device concepts.
Developments in ceria-based soot oxidation catalysts, especially during the last decade, are reviewed. Based on the comparisons of the activity, durability and cost-efficiency of different soot oxidation catalysts, four kinds of applicable ceria-based catalysts have been screened out, which are:(1) CexZr1–xO2 catalyst…
A facile and fruitful CVD method is reported for the first time, to synthesize high-quality hexagonal SnS2 nanosheets on carbon cloth via in situ sulfurization of SnO2. Moreover, highly sensitive phototransistors based on SnS2 with an on/off ratio surpassing 10(6) under ambient conditions and a rising time as short as…
Robust superamphiphobic coatings fabricated by a facile chemical deposition and low surface energy modification were coated on both hard and soft materials to repel water and oils.
Injectable depots that respond to exogenous and endogenous stimuli present an attractive strategy for tunable, patient-specific drug delivery. Here, the design of injectable and multimodal degradable hydrogels that respond to externally applied light and physiological stimuli, specifically aqueous and reducing microen…
Ti-Nb base alloys have been proposed as prospective candidates for Ni-free biomedical superelastic alloys due to their excellent mechanical properties with good biocompatibility, and many kinds of Ti-Nb base alloys exhibiting shape memory effect or superelasticity have been developed up to now. However, typical Ti-Nb…
In this paper we demonstrate that the residual stress introduced by several different surface finishes affects the critical current density for passivation and the passive current density in the anodic polarization curve of austenitic stainless steel and that those critical current densities can be reduced by controll…
Adsorption represents an efficient and economical approach for water purification and substantial research is being performed to develop effective sorbent materials.
As a rising star in two-dimensional (2D) layered materials, transition metal dichalcogenides (TMDs) have attracted tremendous attention for their potential applications in nanoelectronics, optoelectronics and photonics. Driven by the high standards of practical devices, alloying theory has been proposed for modulating…
Boron nitride quantum dots are obtained by a facile sonication-solvothermal technique. They are proven to be promising fluorescent bioimaging probes for bioimaging with remarkably low cytotoxicity and easily integrated into high-performance proton exchange membranes. This work will probably trigger research interest i…
