Defect structures such as boundaries, ripples and wrinkles in graphene have been considered as main causes reducing the electrical properties of graphene. Among them, the formation of a periodic nanoripple array and surface roughening intrinsically occurs as graphene grows on the surface of a metal catalyst during che…
Green and simple synthesis strategies have gained tremendous popularity for the production of anisotropically-shaped noble metallic nanoparticles. The long-term stability of the produced particles, the short timescale of the target reaction(s), as well as the use of non-toxic chemicals, are pivotal features of a usefu…
Degumming of Chinese bivoltine silk with alkaline proteases from various microbial sources was investigated and compared with commercial enzymes. Among the proteases tested, two fungal and two actinomycete proteases were promising, which showed weight loss similar to conventional method (19.58% to 21.78%). Conidiobolu…
We study the depletion-induced self-assembly of indented colloids. Using state-of-the-art Monte Carlo simulation techniques that treat the depletant particles explicitly, we demonstrate that colloids assemble by a lock-and-key mechanism, leading to colloidal polymerization. The morphology of the chains that are formed…
Cotton fabric was functionalized with zinc oxide nanorods using an optimized hydrothermal growth strategy that provides uniform coverage of the cotton surface. The cotton bearing ZnO nanorods exhibits a lower propensity for contact transfer of E. coli than unmodified cotton fabric. The ZnO nanorods also impart modest…
An octadecyltrichlorosilane (OTS) superhydrophobic film using phase‐separation method was prepared to demonstrate the anti‐icing property of superhydrophobic surfaces. The superhydrophobicity of the film at −5 ∘ C was investigated. It was found that the prepared OTS film retained its superhydrophobicity at −5 ∘ C by t…
Continuous natural fiber reinforced thermoplastic materials are expected to replace inorganic fiber reinforced thermosetting materials. However, in the process of fabricating the composite, it is difficult to impregnate the thermoplastic resin into reinforcement fiber because of the high melt viscosity. Therefore, int…
Cancer is a leading cause of death. Mesoporous nanomaterials with stimuli sensitivity have received increasing interest as efficient anti-cancer drug carriers. Here, we report hybrid mesoporous nanoparticles of PEGylated silica-poly[2-(dimethylamino)ethyl acrylate] (PEGylated MSN-g-PDMAEA) that can deliver and release…
We investigate high-pressure induced phase transitions of YF3 and Eu-doped YF3 (YF3:Eu(3+)) by using the angular dispersive synchrotron X-ray diffraction technique at room temperature. It is found that the starting orthorhombic phase transforms into a new high-pressure phase which is identified as hexagonal structure…
A pH-sensitive nano antitumor drug delivery system was prepared by conjugating doxorubicin (DOX) to amphiphilic polyrotaxane (PR)-based block copolymers through a pH-sensitive cis-aconityl moiety. The resulting polymer-drug conjugates were able to self-assemble into polymeric micelles in an aqueous solution with diame…
Gelation of lithocholic acid (LCA) mixed with zwitterionic alkyldimethylamine oxide, (CnDMAO, n = 10, 12, 14, 16, and 18), in water was detected. Hydrogels can only form at an appropriate hydrophilic–hydrophobic balance condition (n = 12, 14, and 16) with the highest gelation capability at n = 12. Microstructures of h…
Reduced graphene oxide (rGO) has been produced using an ammonia (NH3) plasma reduction method. Simultaneous nitrogen doping during the reduction process enabled a rapid and low-temperature restoration of the electrical properties of the rGO. The chemical, structural, and electrical properties of the rGO films were ana…
The effect of volatile boron species on the electrocatalytic activity, microstructure and phase stability of conventional La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3 (LSCF) and nano-structured LSCF infiltrated Gd 0.1 Ce 0.9 O 1.95 (LSCF-GDC) electrodes of solid oxide fuel cell (SOFC) is studied. The cathodes were heat-treated at…
Poly(3,4-ethylenedioxythiophene) (PEDOT) films were produced by chemical oxidative polymerization (in-situ PEDOT) and coating aqueous dispersion (slurry PEDOT). Sheet resistance measured before and after heat treatment showed that slurry PEDOT film remained stable in air while in-situ film degraded resulting in a sign…
A series of Au–silica (nanosphere) catalysts were prepared by in situ synthesis; highly dispersed gold nanoparticles (GNPs, 6.4 nm) were obtained, and catalytic tests showed good catalytic activity and epoxidation selectivity. To investigate the origin of the GNPs, the solids were characterized using X-ray diffraction…
The aim of this study is to find out the development and application of MUC1-expressing ovarian cancer (OVCAR3) by C595 monoclonal antibody-conjugated superparamagnetic iron oxide nanoparticles (SPIONs) using MR imaging. At the end, its use as a nanosized contrast agent MR imaging probe for ovarian cancer detection wa…
A novel and facile strategy for the preparation of a monolithic Ag–CeO2 composite is reported. Here, nanoporous Ag–CeO2 ribbons are successfully prepared through dealloying melt-spun Al79.5Ag20Ce0.5 alloy in a 5 wt% NaOH aqueous solution, followed by calcining in air. The Ag–CeO2 ribbons with a homogeneous pore/grain…
We have carried out first-principles calculations and theoretical analysis to explore the structural, spin-polarized electronic and magnetic properties of bi-layered MoS2 with transition-metal (TM) atoms (Cr, Mn, Fe, Co and Ni) doped in the interlayer. The charge density distribution indicates that the doping TM atoms…
The use of single-walled carbon nanotubes as effective nanoreactors for preparative chemical reactions has been demonstrated for the first time. Extreme spatial confinement of reactant molecules inside nanotubes has been shown to drastically affect both the regioselectivity and kinetics of aromatic halogenation reacti…
Carbon nanotubes (CNTs) have a tremendous amount of potential to become useful components for future practical applications that may become a part of everyday life. While the sp(2) carbon itself is a rather chemically inert material, the issue of residual metal nanoparticle catalysts remains a prominent barrier in the…
