The direct production of γ-valerolactone (GVL), an essential component for next-generation biorefineries, by a straightforward conversion of bio-derived levulinic acid (LA)/formic acid (FA) streams without the externally added fossil-fuel H2 has rarely been achieved. We describe here a sustainable, cost-effective and…
Production of hydrogen (H2) by splitting water using the electrolysis effect is a potential source of clean and renewable energy. However, it usually requires an external power source to drive the oxidation or reduction reactions of H2O molecules, which largely limits the development of this technology. Here, we fabri…
The geometry structures, formation energies and electronic properties of the B-, C- and B/C-doped anatase TiO2 were investigated by the density functional theory (DFT) calculations of first-principles. The results indicated that the visible-light absorption and photocatalytic activities of the B-, C- and B/C-doped ana…
Currently extensive research is focused on developing and designing novel porous materials for clean energy and environmental applications such as reducing the emission of carbon dioxide (CO2). In this work, hybrid monolith aerogels of chitosan (CTS), an environmentally-benign biopolymer, with different amounts of gra…
Biocompatible and biodegradable hydroxyapatite nanoparticles with a hollow core and mesoporous shell structure (denoted as hmHANPs) are synthesized by an opposite ion core/shell strategy and applied to pH-responsive intracellular drug delivery systems (DDS). The synthesized hmHANPs have several advantages over solid h…
This review summarizes selected mechanistic insight garnered from reactions that form bonds between main group elements with liberation of hydrogen, dehydrocoupling or dehydropolymerization reactions. Focus has been made where mechanistic study has been done or provides unique insight as compared to previous work. Thu…
Nanocomposites comprising a P(VDF-HFP) polymer matrix and core-shell structured nanoparticle fillers were prepared, in which a crystalline, ultrathin TiO2 shell layer encapsulates BaTiO3 nanoparticles. A large dielectric constant (>110) was obtained, which was unexpectedly more than 3 times higher than that of the nan…
We report the wet-chemistry synthesis of a new type of porous carbon nanosheet whose thickness can be precisely controlled over the nanometer length scale. This feature is distinct from conventional porous carbons that are composed of micron-sized or larger skeletons, and whose structure is less controlled. The synthe…
This communication reports for the first time the charging of a commercially available mobile phone, using Microbial Fuel Cells (MFCs) fed with real neat urine. The membrane-less MFCs were made out of ceramic material and employed plain carbon based electrodes.
The Cu-based MOF loaded on macroporous carbon (MPC) creates novel Cu-MOF-MPC hybrids for the first time. The obtained Cu-MOF-MPC composites are used as electrocatalysts for the oxidation of NADH and reduction of H2O2 in neutral solution.
Carbon hollow spheres were produced using a sustainable approach, i.e. hydrothermal carbonization, using monosaccharides as carbon precursors and silica nanoparticles as hard-templates. Hydrothermal carbonization is an eco-efficient and cost-effective route to synthesize nanostructured carbonaceous materials from abun…
Anatase TiO2 nanocrystals with {101}, {001} or {010} single facets of 90% level exposure were controllably synthesized from potassium titanate (PT) without fluorine and organic capping surfactants, and characterized by X-ray diffraction patterns (XRD), field emission scanning electron microscopy (FESEM), transmission…
Advances in polymer nanodielectrics over the past 50 years, using colloid science, polymer composite technology, and nanotechnology, are reviewed. Despite rapid progress during the past 10 years, interdisciplinary investigation is needed to yield additional benefit to society.
Polydiacetylenes (PDAs) comprise a class of chromatic polymers which have attracted significant interest over the past 40 years as a promising platform for chemo- and bio-sensing. Specifically, the unique colorimetric and fluorescent transformations of PDA, induced by varied external stimuli, are a core property of th…
Combining chemotherapy with gene therapy has been one of the most promising strategies for the treatment of cancer. Noninvasive MRI with superparamagnetic iron oxide (SPIO) as a contrast agent is one of the most effective techniques for evaluating antitumor therapy. However, constructing a single system that can deliv…
We demonstrate reflection-mode plasmonic color filters based on lithographically patterned silver nanorods with ultrasmall inter-rod gaps. Fine and effective tuning of the plasmon resonance is shown by varying array periodicities. We determine the dependence of reflected intensity on diameter/periodicity ratio and the…
Binary transition metal oxides have been attracting extensive attention as promising anode materials for lithium-ion batteries, due to their high theoretical specific capacity, superior rate performance and good cycling stability. Here, loaf-like ZnMn2O4 nanorods with diameters of 80-150 nm and lengths of several micr…
We demonstrated a facile method to synthesize nanosheet-like cobalt–nitrogen–graphene composites acting as a highly active non precious metal-based catalyst for oxygen reduction reaction.
A novel porous sulfur/carbon nanocomposite was prepared as the cathode material for lithium–sulfur batteries. The porous nanostructure of the composite is beneficial for enhancing the cycle life by accommodating the volume expansion of sulfur particles and adsorbing the polysulfide produced during the electrochemical…
Optical, scintillation, and dosimeter properties of AlN ceramic were reported. AlN sample was SHAPAL, a commercial product of Tokuyama Corp. for mainly a heat sink application. From ultra violet to near infrared wavelengths, it showed 0.02–1% transmittance with visibly translucent appearance. In photoluminescence (PL)…
