The contentious origin of the luminescence of carbon nanodots (CDs) has attracted considerable attention. In this work, we synthesized CDs from orange peel by using a microwave-assisted technique. We investigated the optical properties of the synthesized CDs. Moreover, we studied the effect of matrix addition on the o…
BaBrCl:Eu is a promising scintillator material; however, the crystal growth yield must be improved for it to become commercially viable. This study measures strain accumulations in the crystal lattice which can contribute to cracking during post-growth cooling. Neutron diffraction is used to measure the crystal struct…
High Resolution Image Download MS PowerPoint Slide We have designed a flexible electrochemical transducer film based on PEDOT–titania–poly(dimethylsiloxane) (PTS) for the simultaneous detection of neurotransmitters. PTS films were characterized using various techniques such as transmission electron microscopy, scannin…
We report the synthesis and characterizations of a new FeSe-based compound CsFe 4−δ Se 4, which is closely related to alkali intercalated FeSe superconductors while exhibits distinct features. It does not undergo phase separation and antiferromagnetic transition. Powder neutron diffractions, electron microscopy and hi…
A facile route was used for improving the oil-absorbing performance of Calotropis gigantea fiber (CGF) via a convenient oxidative polymerization of dopamine in the presence of attapulgite (APT) and subsequent instant immersion in an ethanolic solution of 1H,1H,2H,2H-perfluorooctyltriethoxysilane (PFS). The scanning el…
FeVO4 and Fe0.5Er0.5VO4 were prepared and loaded over standard Selective Catalytic Reduction (SCR) supports based on TiO2-WO3-SiO2 (TWS) and redox active supports like CeO2 and CeZrO2 with the aim of finding a suitable formulation for simultaneous soot abatement and NH3-SCR and to understand the level of interaction b…
Solid state thermoelectric cooling is based on the electronic Peltier effect, which cools via an electronic heat current in the absence of an applied temperature gradient. In this work, we demonstrate that equivalently, a phonon Peltier effect may arise in the non-linear thermoelectric transport regime of a dissipativ…
When the rate of loading is faster than the rate at which material absorbs and converts energy to plastic work and damages, then there is an excess of energy that is partly stored in the material's microstructure and the rest of it triggers micro-dynamic excitations. The additional storage necessitates the development…
Abstract Emulsion detonation synthesis ( EDS ) is a newly developed process to synthesize nano‐sized ceramic powders based on the detonation of 2 water‐in‐oil emulsions. The process provides high pressure and temperature along with rapid quenching. In this work, we report the formation of wurtzite phase BN (w‐ BN ) fo…
To predict the response of a biochemical system, knowledge of the intrinsic and effective rate constants of proteins is crucial. The experimentally accessible effective rate constant for association can be decomposed in a diffusion-limited rate at which proteins come into contact and an intrinsic association rate at w…
Abstract Gadolinium aluminum gallium garnet doped with cerium (Gd 2.99 Al 2.00 Ga 3.00 O 12.00 :Ce 0.01 , or GAGG :Ce) powders has been synthesized with high‐energy ball milling ( HEBM ) and solution combustion synthesis ( SCS ) techniques. The structures and morphologies of the powders were characterized through use…
In the last decades, simulations have been established in several fields of science and industry to study various phenomena by solving, inter alia, partial differential equations. For an efficient use of current and future high performance computing systems, with many thousands of computation ranks, high node-level pe…
Abstract The generation of oxygen‐containing functionalities on pristine carbon surfaces is investigated and shown to be light sensitive, specifically to infra‐red radiation. A mechanistic route involving singlet oxygen, 1 O 2 , is proposed and evidenced.
High Resolution Image Download MS PowerPoint Slide Ammonia borane (NH 3 -BH 3 ) is of interest as a hydrogen storage material because of its ease of use and its ability to release three molar equivalents of H 2 (g) via catalytic hydrolysis. Most heterogeneous catalysts for ammonia borane hydrolysis are nanoparticles c…
Understanding the mechanism of adsorption and self-assembly of surfactants on graphene is highly important to perform better optimization of the graphene dispersion process. Because of Gemini surfactants’ special structure, they have a high charge capacity, high hydrophobicity, and unique self-assembly properties comp…
Aluminum carbide cluster anions Al n C 2 – ( n = 5–13) were observed as the most dominant products in the gas-phase reactions of laser-ablated Al n – with organic molecules, such as methanol, ethanol, pentane, acetonitrile, or acetone. Density functional theory calculations predicted two possible isomeric structures f…
New soluble biopolyimides were prepared from a diamine derived from an exotic amino acid (4-aminocinnamic acid) with several kinds of tetracarboxylic dianhydride. The biopolyimide molecular structural flexibility was tailored by modifying the tetracarboxylic dianhydride moiety. The obtained polyimides were soluble in…
A series of new thermotropic liquid crystals (LCs) containing azobenzene units was synthesized. The structures of the compounds were characterized by means of NMR and FTIR spectroscopy. Their mesomorphic behaviors were investigated via differential scanning calorimetry (DSC) and polarizing optical microscopy (POM). Ba…
Malignant glioma is one of the most challenging central nervous system diseases to treat and has high rates of recurrence and mortality. Current therapies often fail to control tumor progression or improve patient survival. Marinobufagenin (MBG) is an endogenous mammalian cardiotonic steroid involved in sodium pump in…
Electric-double-layer transistors (EDLTs), which consist of ionic liquids (IL) as gate dielectrics, have attracted keen interest owing to dramatic modulation of physical properties by high-density carrier accumulation and tuning. In this study, EDLTs based on the superconducting ultrathin FeSe film with multivalent IL…
