We employ ab-initio electronic structure calculations to search for spin gapless semiconductors among the inverse Heusler compounds. The occurrence of this property is not accompanied by a general rule and results are materials specific. The six compounds identified show semiconducting behavior concerning the spin-dow…
The graphene chemical vapour deposition (CVD) technique at substrate temperatures around 300 °C by a microwave plasma sustained by surface waves (surface wave plasma chemical vapour deposition, SWP-CVD) is discussed. A low-temperature, large-area and high-deposition-rate CVD process for graphene films was developed. I…
Pentacenequinone derivative 3 forms luminescent supramolecular aggregates both in bulk as well as in solution phase. In bulk phase at high temperature, long-range stacking of columns leads to formation of stable and ordered columnar mesophase. Further, derivative 3 works as sensitive chemosensor for picric acid (PA) a…
The interaction of water molecules with metal surfaces is typically weak and as a result van der Waals (vdW) forces can be expected to be of importance. Here we account for the systematic poor treatment of vdW forces in most popular density functional theory exchange-correlation functionals by applying accurate non-lo…
This article describes a robust method for the facile synthesis of small Ag nanocubes with edge lengths controlled in the range of 18-32 nm. The success of this new method relies on the substitution of ethylene glycol (EG)--the solvent most commonly used in a polyol synthesis--with diethylene glycol (DEG). Owing to th…
Magnetic field-induced strain (MFIS) of 12% is reported in ferromagnetic Ni46Mn24Ga22Co4Cu4 martensite exhibiting non-modulated (NM) tetragonal crystal structure with lattice parameter ratio c/a>1. The strain was measured at ambient temperature in a magnetic field of the order of 1 T. The twinning stress σTW an…
A high-quality graphene transparent conductive film was fabricated by roll-to-roll chemical vapor deposition (CVD) synthesis on a suspended copper foil and subsequent transfer. While the high temperature required for the CVD synthesis of high-quality graphene has prevented efficient roll-to-roll production thus far, w…
Abstract Oil/water separation is a worldwide challenge. Learning from nature provides a promising approach for the construction of functional materials with oil/water separation. In this contribution, inspired by superhydrophobic self‐cleaning lotus leaves and porous biomaterials, a facile method is proposed to fabric…
As polymers and polymeric materials are "the" smart invention and technological driving force of the 20th century, the quest for self-healing or self-repairing polymers is strong. The concept of supramolecular self-healing materials relies on the use of noncovalent, transient bonds to generate networks, which are able…
There has been a great interest in application of nanoparticles as biomaterials for delivery of therapeutic molecules such as drugs and genes, and for tissue engineering. In particular, biopolymers are suitable materials as nanoparticles for clinical application due to their versatile traits, including biocompatibilit…
Abstract Carbon nanotube (CNT) formulations based on commercially available aqueous dispersions were printed using flexographic printing on a polycarbonate film which was provided with a polyethyleneimine‐based primer layer to improve the wetting and adhesion properties. Depending on the formulation, the structured CN…
The cotton fabrics with the character of anti-crease were obtained by introducing foam technology. It is observed from experimental results that cross-linking agent, curing temperature and curing time all have significant effects on the wrinkle recovery angle and the mechanical property of fabrics. In addition, foam r…
Short-chain dehydrogenases/reductases (SDRs) encompass a large and functionally diverse family of enzymes with representative members in all kingdoms of life. Despite the wealth of reactions catalyzed by SDRs, they operate through a well-conserved and efficient reaction mechanism centered in a conserved catalytic tetr…
Abstract A simple coacervation technique was used to coat a functional paper with gelatin microcapsules containing geraniol to prepare functional papers with sustained fragrance release. This method eliminated the need for microcapsule preparation and coating with a binder. A gelatin solution containing geraniol and T…
Colloidal particles in a water-lutidine (WL) binary liquid mixture experience temperature-dependent attraction close to the mixture's demixing temperature. This temperature-tunable interaction can be potentially harnessed to assemble colloids and grow colloidal crystals. In this article, for the first time a novel att…
Cotton fabric with improved antibacterial properties is always invited for effective use in wound dressing and healing applications. In this study, poly( N-isopropyl acrylamide) network has been produced in situ in porous cotton cellulose fabric by photo polymerization using UV-radiation. The thermoresponsiveness of t…
Abstract The aim of this study was to examine the physical, mechanical, and thermo‐physical properties of high‐density polyethylene (HDPE) modified with talc. Different weight fractions of talc (up to 35 wt %) were compounded with an HDPE matrix containing 2.5 wt % of carbon black (CB) in a twin‐screw compounder. The…
Abstract Condensation reactions between tetraethyl orthosilicate and linear aliphatic diol monomers at moderately high temperatures in proper stoichiometric ratios gave crosslinked poly(orthosilicate)s. The synthesized crosslinked polymers were found to be insoluble in common organic solvents, such as tetrahydrofuran,…
Poly(ferrocenyl(3-bromopropyl)methylsilane) and poly(ethylene imine) are employed in a layer-by-layer deposition process to form covalently connected, redox-active multilayer thin films by means of an amine alkylation reaction. The stepwise buildup of these multilayers on silicon, ITO, and quartz substrates was monito…
Fly ash (FA) can be used as a filler in rubber vulcanizates to get rid off their waste. Polymer composite based on chlorinated styrene butadiene rubber (CSBR)/containing varying amount of FA composites has been developed by melt compounding followed by dicumyl peroxide vulcanization. The influence of increased loading…
