Layered transition metal dichalcogenides (TMDs), such as MoS2, are candidate materials for next generation 2-D electronic and optoelectronic devices. The ability to grow uniform, crystalline, atomic layers over large areas is the key to developing such technology. We report a chemical vapor deposition (CVD) technique…
Red upconversion luminescence (UCL) is selectively enhanced by about 7 times via Fe(3+) codoping into a NaYF4:Yb,Er nanocrystalline lattice. The maximum red-to-green ratio (R/G) as well as the overall integrated UCL intensity features at an Fe(3+) content of 20 mol%. The size and phase of nanocrystals are simultaneous…
Hypercrosslinked materials have experienced a great expansion in both the synthetic approach and the field of applications.
This work is mainly focused on the investigation of the influence of the amount of a few CeO2 on the physicochemical and catalytic properties of CeO2-doped TiO2 catalysts for NO reduction by a CO model reaction. The obtained samples were characterized by means of XRD, N2-physisorption (BET), LRS, UV-vis DRS, XPS, (O2,…
This review summarizes the applications of photochromic sensors in the areas of specific recognition and multi-analyte discrimination.
A recently discovered two-dimensional (2D) layered material phosphorene has attracted considerable interest as a promising p-type semiconducting material. In this work, thermal conductivity (κ) of monolayer phosphorene is calculated using large-scale classical non-equilibrium molecular dynamics (NEMD) simulations. The…
Nanoparticles (NPs) are considered a promising tool in both diagnosis and therapeutics. Theranostic NPs possess the combined properties of targeted imaging and drug delivery within a single entity. While the categorization of theranostic NPs is based on their structure and composition, the pharmacokinetics of NPs are…
PPy was firstly formed on the surface of GO modified by CTAB, and the as-prepared PPy/GO-CTAB was further reduced to synthesize PPy/rGO-CTAB composite by vitamin C under a mild condition.
The recently developed poly(glycerol sebacate) (PGS) has been gaining attraction as a biomaterial for tissue engineering applications. Reported in 2002, a simple polycondensation method was developed to synthesize PGS for soft tissue engineering applications. It has since become a highly sought after biomaterial due t…
A superhydrophobic fabric was first fabricated by a novel mussel-inspired strategy with the aid of folic acid and a low concentration of dopamine without any additional nanoparticle incorporation. A mini boat of this fabric can automatically recycle oil spills while floating freely on water.
Mechanically robust Bi 2 Te 3 -based materials with excellent thermoelectric performance are synthesized by ultra-fast self-propagating high-temperature synthesis in less than 20 min.
A flexible wire-shaped fiber asymmetric supercapacitor shows perfect bending properties, high performance and good cycling stability.
Graphene quantum dots (GQDs) have attracted increasing interest because of their excellent properties such as strong photoluminescence, excellent biocompatibility and low cost. Herein, we develop a general method for the synthesis of doped and undoped GQDs, which relies on direct carbonization of organic precursors in…
A highly stable modular platform, based on the sequential covalent attachment of different functionalities to the surface of core-shell mesoporous silica nanoparticles (MSNs) for targeted drug delivery is presented. A reversible pH-responsive cap system based on covalently attached poly(2-vinylpyridine) (PVP) was deve…
In operando Raman spectroscopy was used to monitor the origin of the pseudocapacitive behavior of Mn 3 O 4 electrodes during charging/discharging processes.
A novel, efficient and green MOFs-templated sulfidation route has been developed to synthesize Cu(1.96)S-C hybrid composites, in which ultrafine Cu(1.96)S nanoparticles are embedded uniformly within porous carbon octahedra. The as-synthesized composites exhibit high specific capacitance and good cycling performance in…
Amino-functionalized fluorescent carbon dots have been prepared by hydrothermal treatment of glucosamine with excess pyrophosphate. The produced carbon dots showed stabilized green emission fluorescence at various excitation wavelengths and pH environments. Herein, we demonstrate the surface energy transfer between th…
Carbon nanotubes have emerged as unique carbon allotropes that bear very interesting prospects in catalysis.
The exploration of high Faradic redox active materials with the advantages of low cost and low toxicity has been attracting great attention for producing high energy storage supercapacitors. Here, the high Faradic redox active material of Cu7S4-NWs coated on a carbon fiber fabric (CFF) is directly used as a binder-fre…
