Recent research and development of colorless and transparent high-temperature-resistant polymer optical films (CHTPFs) have been reviewed. CHTPF films possess the merits of both common polymer optical film and aromatic high-temperature-resistant polymer films and thus have been widely investigated as components for mi…
The transport and conducting properties of oxygen and titanium deficient cubic barium titanate (BT) were studied using atomistic simulations. The thermal expansion coefficient is shown to decrease when the number of titanium and oxygen vacancies increases. The influence of point defect concentration on the diffusion a…
A novel triazole nucleoside analogue was discovered to exhibit potent anticancer activity in prostate cancer cells via down-regulating heat shock factor 1 (HSF1) and related heat shock proteins, along with the consequential inhibition of androgen receptor (AR) expression and transactivation, arresting the cell cycle i…
This study proposes a flexible active power filter (APF) controller operating selectively to satisfy a set of desired load performance indices defined at the source side. The definition of such indices, and of the corresponding current references, is based on the orthogonal instantaneous current decomposition and conf…
Antenna-coupled single- and bi-metal nanothermocouples (ACNTCs) and thermopiles for IR detection are fabricated and tested. These devices comprise a dipole antenna and a nanoscale thermocouple with lead lines. Polarization-dependent responses of antenna-coupled thermopiles with various array sizes are investigated. Th…
In this work, we present the results obtained using a CO2 laser source at 10.6 μm wavelength for the study of the non-melt annealing of phosphorus doped germanium in the millisecond regime. Main objective of this paper is the demonstration of electrically active n+-p junctions in germanium by implanting phosphorus in…
Multilayered cell sheets have been produced from bone marrow-derived mesenchymal stem cells (MSCs) for investigating their adhesion properties onto native porcine heart tissue. Once MSCs reached confluence after a 7-day culture on a temperature-responsive culture dish, a MSCs monolayer spontaneously detached itself fr…
Raman measurements of a Fano-type surface phonon mode associated with Dirac surface states (SS) in Bi2Se3 topological insulator thin films allowed an unambiguous determination of the electron-phonon coupling strength in Dirac SS as a function of film thickness ranging from 2 to 40 nm. A non-monotonic enhancement of th…
Finding small molecules that target allosteric sites remains a grand challenge for ligand discovery. In the protein kinase field, only a handful of highly selective allosteric modulators have been found. Thus, more general methods are needed to discover allosteric modulators for additional kinases. Here, we use virtua…
The typically stable Zr-based metal-organic frameworks (MOFs) UiO-66 and UiO-66-NH2 were treated with tetrafluoromethane (CF4 ) and hexafluoroethane (C2 F6 ) plasmas. Through interactions between fluoride radicals from the perfluoroalkane plasma and the zirconium-oxygen bonds of the MOF, the resulting materials showed…
Differential geometry (DG) based solvation models are a new class of variational implicit solvent approaches that are able to avoid unphysical solvent-solute boundary definitions and associated geometric singularities, and dynamically couple polar and non-polar interactions in a self-consistent framework. Our earlier…
Ternary nanowires (NWs) often exhibit varying material composition along the NW growth axis because of different diffusion properties of the precursor molecules. This constitutes a problem for optoelectronic devices for which a homogeneous material composition is most often of importance. Especially, ternary GaInP NWs…
ABSTRACT Poly(vinyl alcohol) (PVA) nanofibers containing halloysite nanotubes (HNTs) loaded with sodiumd‐pantothenate (SDP) were successfully fabricated via simple blend‐electrospinning. SDP was efficiently loaded into the innate HNT lumen with an SDP/HNT mass ratio of 1.5:1 via vacuum treatment. The SDP‐loaded HNT‐in…
Silica aerogels are porous ultralight materials with exceptional physical properties that are promising materials for thermal insulation applications. This paper theoretically and experimentally investigates the spectral scattering and absorption coefficients of a porous silica aerogel. Silica aerogel samples were pre…
ABSTRACT The structure, rheological response, and ionic conductivity of ABA brush block copolymer (BBCP) ion gels containing 1‐butyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide ([BMI][TFSI]) at polymer concentrations spanning 5‐50 wt % (Φgel) were studied by small angle X‐ray scattering, dynamic mechanical a…
We report a new crosslinked polymersome with pH-responsive swelling properties through acidic hydrolysis of hydrophobic contents from the amphiphilic polymer chains. Its unique stability under physiological conditions and large swelling capability under low pH conditions give this polymersome promising potential for a…
Hydrogen sulfide generation in oil production is a constant cause of concern. In several cases this phenomenon occurs due to the action of sulfate-reducing bacteria. Various methods, including biocides and nitrate addition, have been used to control the activity of these microorganisms, but they are expensive and have…
Small interfering RNAs (siRNA) are emerging as a new opportunity for treatment of various diseases, including viral and cancer diseases via knocking down a specific gene that involves in disease development. But their clinical application is hampered because of susceptibility to degradation and difficult delivery of s…
Tailoring the vortex pinning strength of YBCO thin films by systematic incorporation of hybrid artificial pinning centers, Jha, Alok K, Matsumoto, Kaname, Horide, Tomoya, Saini, Shrikant, Mele, Paolo, Ichinose, Ataru, Yoshida, Yutaka, Awaji, Satoshi
Abstract Porous coordination polymers or metal–organic frameworks have been proposed as promising catalyst materials since their discovery. A fundamental problem associated with MOF‐based catalysts is the stability during their catalytic performance, especially in liquid‐phase catalysis. Herein, we report on the contr…
