Rambutan-like heterostructures consisting of Ni microspheres coated with oriented multiwall carbon nanotubes (MWCNTs) were synthesized by the one-pot thermal decomposition of a mixture of organic matter and Ni precursors. X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and Raman spec…
This work reports a flexible supercapacitor based on vanadium oxide–polyaniline composites (VP-1) with a large potential window and high energy density.
Reactive oxygen species (ROS) play key roles in many physiological processes, such as cell signaling and host innate immunity. However, when they are overproduced, ROS may damage biomolecules in vivo and cause diseases such as cardiovascular or neurodegenerative diseases, cancer, and so forth. Oxidative stress is usua…
Recent advances in producing pre-defined 2D patterns of upconversion nanophosphors via photolithography and printing techniques present new opportunities for the use of these materials in security applications. Here, we demonstrate an RGB additive-color printing system that produces highly-resolved pre-defined pattern…
Oligo(phenylenevinylene)s (OPVs) are extensively investigated π-conjugated molecules that exhibit absorption and fluorescence in the UV-Vis spectral region, which can be widely tuned by chemical functionalisation and external control (e.g. solvent, temperature, pH). Further modulation of the optoelectronic properties…
Sunlight absorption within the electrolyte impacts the performance and design of high-efficiency tandem PEC devices as evidenced by detailed balance calculations.
A systematic study on the use of 9,9-dialkylfluorene homopolymers (PFs) for large-diameter semiconducting (sc-) single-walled carbon nanotube (SWCNT) enrichment is the focus of this report. The enrichment is based on a simple three-step extraction process: (1) dispersion of as-produced SWCNTs in a PF solution; (2) cen…
Flexible all-solid-state supercapacitors based on graphene films with different gel electrolytes are demonstrated. During the bending and cycling of graphene-based solid-state supercapacitor, the stability was maintained without sacrificing the electrochemical performance.
Two types of homogeneous NiCo2O4 nanosheet@NiCo2O4 nanorod and heterogeneous NiCo2O4 nanosheet@NiO nanoflake hierarchical core–shell arrays are synthesized via facile solution methods in combination with a simple thermal treatment. In both cases, the NiCo2O4 nanosheets serve as the core backbone for anchoring the shel…
Nanomaterials are prone to influence by chemical adsorption because of their large surface to volume ratios. This enables sensitive detection of adsorbed chemical species which, in turn, can tune the properties of the host material. Recent studies discovered that single and multi-layer molybdenum disulfide (MoS2) film…
A novel anti-icing superhydrophobic hybrid material synthesized by surface initiated AGET ATPR can prevent ice formation.
The energy barrier of the CO oxidation for the rate limiting step on Al-embedded graphene is only 0.32 eV.
We report a fluorescent light-up probe AIE-Lyso-1 for in situ visualization of lysosomal esterase activity. The probe is based on a salicyladazine fluorogen, which is conjugated with esterase reactive acetoxyl groups and lysosome-targeting morpholine moieties. The probe has characteristics of both aggregation-induced…
An electrochemical approach has been employed for the preparation of photoluminescent carbon nanodots (C-dots) from glycine under alkaline conditions. The formation of C-dots is through electro-oxidation, electro-polymerization, carbonization, and passivation. The as-prepared C-dots possess excitation-wavelength-depen…
The effect of graphene oxide (GO) on the mechanical properties and the curing reaction of Diglycidyl Ether of Bisphenol A/F and Triethylenetetramine epoxy system was investigated. GO was prepared by oxidation of graphite flakes and characterized by spectroscopic and microscopic techniques. Epoxy nanocomposites were fa…
This review provides a comprehensive assessment of recent progress in polypyrrole derivatives which are specially designed for electrochromic applications.
Intercalation of polysulfides into LDHs forms layered composites that can separate Hg 2+ , Ag + and Cu 2+ from mixed ions with high selectivity and capacity.
A biocompatible amine functionalized fluorescent carbon dots were developed and isolated for gram scale applications. Such carbogenic quantum dots can strongly conjugate over the surface of the chloroplast and due to that strong interaction the former can easily transfer electrons towards the latter by assistance of a…
In general, optical emission in the solid-state is red-shifted with respect to the solution phase. A series of recently synthesized compounds exhibits aggregation induced blue-shifted emission (AIBSE) phenomena. By employing a polarizable continuum model (PCM) and a hybrid quantum mechanics/molecular mechanics (QM/MM)…
In recent days, automobile and construction industries are focus on the light weight, environmental friendly materials with good mechanical properties. Glass fiber reinforced composites have excellent specific properties and are widely used because of reduced mass. However the manufacturing of glass fibers and end of…
