Nitrogen-doped graphene hydrogels were synthesized using amino acids as doping agents. The acidity of the amino acid affects the morphology and ultimately the electrochemical performance of the material.
We report on the reduction of the thermal conductivity in ultra-thin suspended Si membranes with high crystalline quality. A series of membranes with thicknesses ranging from 9 nm to 1.5 μm was investigated using Raman thermometry, a novel contactless technique for thermal conductivity determination. A systematic decr…
An efficient red phosphor, BaSiF6:Mn4+ free of manganese oxide impurities, has been synthesized by using a one-step hydrothermal method at 120 °C for 12 h. The synthesis and chemical reactions have been investigated in detail and it includes: (a) influence of starting materials, concentrations of KMnO4 and HF, reactio…
HDI-filled silica/polyurea hybrid microcapsules with superior thermal stability and solvent resistance were prepared and applied to one-part self-healing anticorrosion coatings.
BACKGROUND: There is increased demand for improved disinfection methods due to microorganisms resistant to multiple antimicrobial agents. Numerous types of disinfectants are available with different properties; but the proper disinfectant must be carefully selected for any specific application to obtain the desired an…
A hydrogen bonding interaction is formed and broken between N of the pyridine ring and H–N of urethane in the PEG4000–MDI–BIN polymer due to the deprotonation and protonation of pyridine rings by simply changing the pH value of the external environment, and can reversibly switch both the shape memory and drug release.
The aim of this paper is to determine how microgels adsorb at a model oil-water interface and how they adapt their conformation to compression, which gives rise to surface elasticity depending on the microgel packing. The structure of the film is determined by the Langmuir films approach (forced compression) and compa…
A simple, fast, energy and labour efficient, carbon dot synthesis method involving only the mixing of a saccharide and base is presented.
Highly conductive carbon–CoO nanowire array electrodes on 3D nickel foam were designed with ultrahigh specific capacitance (3282.2 F g <sup>−1</sup> ), approaching the CoO theoretical value. Assembled into an asymmetric supercapacitor, the energy density is ∼58.9 W h kg <sup>−1</sup> , a record among Co-based supercap…
This tutorial review will focus on the removal of organic pollutants from the aqueous phase by mesoporous silica. After a brief discussion about mesosilica formation (MCM-41 and SBA-15) and silica surface modification, the review will focus on the use of mesosilica for the removal of (i) organic compounds, (ii) organi…
Creating a practical and energy-efficient method with high efficacy to separate oil–water mixtures, especially those stabilized by surfactants, has proven to be extremely challenging.
The fabricated superhydrophobic–superoleophilic mesh is bent into a V-shape-channel to guarantee floating oils are always in contact with the mesh.
Polyimide nanocomposites with boron nitride-coated multi-walled carbon nanotubes (BN- <italic>c</italic> -MWCNTs) were successfully prepared with enhanced thermal conductivity and electrical insulation.
An all solid-state micro-supercapacitor is fabricated using patterned photoresist-derived porous carbon electrodes and an ionogel electrolyte. Excellent long-term stability and high specific energy are obtained.
Color-tunable green-red emitting La <sub>3</sub> GaGe <sub>5</sub> O <sub>16</sub> :Tb <sup>3+</sup> ,Eu <sup>3+</sup> phosphors were prepared and the energy transfer process was discussed.
Recent research on electrochemical capacitors using transition metal hydroxides as electrode materials is reviewed.
Metal and metal oxide nanoparticles are often used as industrial catalysts or to improve product's functional properties. Recent advanced nanotechnology have been expected to be used in various fields, ranging from sensors, environmental remediation to biomedicine, medical biology and imaging, etc. However, the growin…
Thermoelectric materials have been extensively used in space satellites, automobiles, and, more recently, in solar thermal application as power generators. Solar thermoelectric generators (STEGs) have enjoyed rapidly improving efficiency in recent years in both concentrated and non-concentrated systems. However, there…
The combination of the high micropore surface area and the controlled mesopore size and mesopore/micropore ratio is responsible for high specific capacitance and excellent rate capability.
A Bi <sub>2</sub> MoO <sub>6</sub> /Zn–Al LDH heterostructure exhibits significantly enhanced photodegradation efficiency for RhB relative to Bi <sub>2</sub> MoO <sub>6</sub> under visible light irradiation.
