Scaffold proteins are crucial regulators of many key signaling pathways that function by interacting with multiple members of a signaling pathway and tethering them into complexes. We recently identified novel scaffold proteins that respectively regulate p53 and ERK pathways in gastrointestinal tumors. ArhGAP30 is a m…
An optically switchable diffraction grating has been made in a thin film containing a photochromic dye and amorphous polycarbonate. We show that a film containing the dye 5-chloro-1,3-dihydro-1,3,3-trimethylspiro[2H-indole-2,3′-(3H)naphth[2,1-b](1,4)oxazine] can be optically processed so that a diffraction grating can…
One of the major remaining barriers to the widespread adoption of thermally activated shape memory polymer is the method used to heat them. Presented is an investigation into using 5 μm nickel particles aligned into chains as embedded joule heaters for epoxy shape memory polymer. The high density of particle chain hea…
Purpose – The purpose of this paper is to investigate factors affecting the impression of elegance of a jacket’s appearance. Design/methodology/approach – A questionnaire survey on the impression of jacket appearance was conducted using images of jackets of Japanese and European brands. A paired comparison and sensory…
Currents through the poly(3,4-ethylenedioxythiophene) doped with poly(styrenesulfonate) and ZnO nanoparticles (PEDOT:PSS:ZnO)/CdS/indium tin oxide (ITO) hetero-structures are studied. The authors introduced the electrodeposition technique with sulfide treatment to improve the film quality of CdS. It is shown that sulf…
Carbohydrate-binding modules (CBMs) are discrete parts of carbohydrate-hydrolyzing enzymes that bind specific types of carbohydrates. Ultra high-resolution X-ray crystallographic studies of CBMs have helped to decipher the basis for specificity in carbohydrate-protein interactions. However, additional studies are need…
Purpose – The purpose of this paper is to study the non-isothermal degradation kinetics of recycled polybutylene terephthalate, polytrimethylene terephthalate and polyethylene terephthalate using thermogravimetric analysis (TGA) in a nitrogen atmosphere. Design/methodology/approach – To achieve this goal, the author u…
In the past two decades, the rapid progress of nanotechnology, ranging from novel nanoelectronics to molecular assemblies, to nanocomposites, tissue engineering, and biomedicine, has taken place. Nanomaterials, due to their exceptional mechanical, thermal, and electronic properties, have restructured several aspects o…
Unraveling the influence that low dimensionality has upon the spin's stability in two-dimensional (2D) systems is instrumental for the efficient engineering of energy barriers in ultrathin magnetic layers. Taking rare-earth-based ultrathin multilayered nanostructures as a model system, we have investigated the dissimi…
Abstract An ambient pressure polymorph of K2Ca3Si3O10 is prepared by firing and annealing a 1:3:3 molar mixture of K2CO3, CaCO3, and amorphous SiO2 (corundum boat, 900 °C, 24 h).
En el presente estudio se analizo el potencial de biodegradacion del polietileno de baja densidad LDPE a partir de la actividad del hongo Pycnoporus sanguineus UTCH03. Para realizar las pruebas se tomo el polietileno de baja densidad (LDPE) como parte del sustrato de crecimiento en fase solida estableciendo a escala d…
This article reports the synthesis and characterization of several types of organic–inorganic nanocomposites based on epoxy resin/monoglycidylether-terminated poly(dimethylsiloxane) reinforced with 2, 5, or 10 wt% polyhedral oligomeric silsesquioxanes (POSS) bearing one glycidyl (1GE-POSS) or eight glycidyl(8GE-POSS)…
Phenylethynyl-terminated polyimide (PI)/carboxylated multiwalled carbon nanotube (MWCNT) composite films were synthesized from 4,4′-oxydianiline, carboxylated MWCNTs, and 3,3′,4,4′-biphenyl tetracarboxylic dianhydride and capped by 4-phenylethynylphthalic anhydride through in situ polymerization under sonication. The…
Abstract This study reports on the synthesis of polymer polyaniline, a conductive polymer by nature, and the preparation of polyaniline/carbon particle (PANI/CP) composites by in situ polymerization. The solution properties and conductivities in solution of synthesized PANI and PANI/CP materials were analyzed. The vis…
We have evaluated tunnel barriers formed in multi-walled carbon nanotubes (MWNTs) by an Ar atom beam irradiation method and applied the technique to fabricate coupled double quantum dots. The two-terminal resistance of the individual MWNTs was increased owing to local damage caused by the Ar beam irradiation. The temp…
The potential energy curves and dipole moments for the low-lying electronic states of the NF molecule are found by using highly accurate multireference configuration interaction plus the Davidson correction with the AV5Z basis set. All 16 electrons are used in the correlation energy calculations, which are used to cha…
Vertically structured Si quantum dots (QDs) solar cells with molybdenum (Mo) interlayer on quartz substrates would overcome current crowding effects found in mesa-structured cells. This study investigates the compatibility between boron (B) doped Si QDs bilayers and Mo-fused silica substrate. Both Si/SiO2 and Si/SiNx…
Chinese Academy of Sciences Institute of Plasma Physics (ASIPP) Experimental Advanced Superconducting Tokamak (EAST) has designed and built a new outer divertor with an ITER-like cooling system. As part of a joint collaboration, the Plasma Science and Fusion Center at MIT performed analyses on the EAST design to deter…
The incidence of yeast cells and wine polysaccharides and polyphenols in the formation of adherent KHT crystals on stainless steel surfaces during cold stabilization was investigated by scanning electron microscopy. Additives were responsible for differences in the deposit configuration, the crystal shape and size as…
