The 'graphene rush' that started almost a decade ago is far from over. The dazzling properties of graphene have long warranted a number of applications in various domains of science and technology. Harnessing the exceptional properties of graphene for practical applications however has proved to be a massive task. Apa…
A round robin test aiming at measuring the high-temperature thermoelectric properties was carried out by a group of European (mainly French) laboratories (labs). Polycrystalline skutterudite Co0.97Ni0.03Sb3 was characterized by Seebeck coefficient (8 labs), electrical resistivity (9 labs), thermal diffusivity (6 labs)…
In this work, we present a simple strategy of fabricating an N-doped graphene oxide coating on stainless steel for protective applications.
The pH sensitivity of CDs is associated with the surface structure.
Graphene/cotton composite fabrics were successfully synthesized via a facile “dipping and drying” process followed by a NaBH 4 reduction method.
The authors review thermal properties of graphene and few‐layer graphene (FLG), and discuss applications of these materials in thermal management of advanced electronics. The intrinsic thermal conductivity of graphene – among the highest of known materials – is dominated by phonons near the room temperature. The examp…
In recent years, a variety of ionic liquids (ILs) were found to be capable of dissolving cellulose and mechanistic studies were also reported. However, there is still a lack of detailed information at the molecular level. Here, long time molecular dynamics simulations of cellulose bunch in 1-ethyl-3-methylimidazolium…
Comparison of structure and electromagnetic interference shielding performance for silver nanostructures hybrid polyimide foams.
Electrons and holes from photo-excited P3HT can transfer to rGO leading mostly to recombination while only electrons transfer to GO.
Ce doped Cu/ZSM-5 catalysts were prepared by the incipient-wetness-impregnation method, and the effect of Ce doping on the structure and the catalytic performance was investigated in detail for the selective catalytic reduction of NO with NH 3
A molecular compass-like behaviour is found in a perovskite-type cage compound (HIm)2[KCo(CN)6] (HIm = imidazolium cation). The dynamic changes in the HIm cation from the static to rotating state along with the rearrangement of the host cage result in switchable and anisotropic dielectric constants.
The present work demonstrates a new simple hand-picking technique for the 100% recovery of a CuO nanosphere photocatalyst.
We theoretically demonstrate that the two-dimensional porous C2N sheet exhibits an extremely high selectivity and large permeance in favour of H2 among other atmospheric gases. This experimentally available porous C2N is superior to traditional membranes, such as polymers and silica, and could have great potential for…
increasing from 36% up to 94%. This is a significant improvement in Pickering emulsifier efficiency compared to that reported previously for similar vesicles with smooth surfaces. In summary, nanoparticles with appreciable surface roughness are much more effective Pickering emulsifiers and this parameter can be readil…
Varying interfacial distance can control tunable Schottky contacts and barriers in hybrid graphene–phosphorene nanocomposites.
This review examines how the concepts and ideas of crystallization can be extended further and applied to the field of mesoscopic soft materials. It concerns the structural characteristics vs. the macroscopic performance, and the formation mechanism of crystal networks. Although this subject can be discussed in a broa…
A B S T R A C T This review focuses on tremendous benefits of nanotechnology in food industry in terms of food processing, packaging, safety and quality control. Nanotechnology can modify permeability of packaging material, increasing barrier properties, improving mechanical and heat-resistance, developing active anti…
PCTF-4 with benzothiadiazole exhibited the highest CO 2 uptake (20.5 wt%) and CO 2 /N 2 selectivity (56) among the reported covalent triazine-based frameworks.
We study the dynamics of the formation of multiple hydrogen bonds between ionic liquid anions and cellulose using molecular dynamics simulations. We examine fifteen different ionic liquids composed of 1-alkyl-3-methylimidazolium cations ([Cnmim], n = 1, 2, 3, 4, 5) paired with either chloride, acetate or dimethylphosp…
Individual mammalian cells were coated with cytoprotective and degradable films by cytocompatible processes maintaining the cell viability. Three types of mammalian cells (HeLa, NIH 3T3, and Jurkat cells) were coated with a metal-organic complex of tannic acid (TA) and ferric ion, and the TA-Fe(III) nanocoat effective…
