Scandium (Sc) contacted n-type carbon nanotube (CNT) field-effected transistors (FETs) with back and top-gate structure have been fabricated, and their stability in air were investigated. It was shown that oxygen and water molecules may affect both the nanotube channel and Sc/nanotube contacts, leading to deteriorated…
This study examines the effect of electrospun polyethylene terephthalate mats fiber diameter, orientation, and surface properties on the Human Aortic Endothelial Cell behavior. Mats with two different average fiber diameters (740 +/- 200 nm and 1.8 +/- 0.2 microm); orientations (low and high); NaOH-treated and untreat…
In self-assembly, the anisotropy of the building blocks and their formation of complex structures have been the subject of considerable recent research. Extending recent research on Janus particles and completing the study of Janus spheroids, we conduct a systematic investigation on the self-assembly of Janus prolate…
Second-order perturbation theory based on multiple time scale analysis is used to illuminate three-phonon scattering processes in the one-dimensional anharmonic monoatomic crystal. Molecular dynamics simulation techniques in conjunction with spectral energy density analyses are used to quantify phonon mode lifetime in…
When irradiated by acoustic waves, gas bubbles can generate divergent spherical waves, which are frequently used to detect the sizes and number density of the gas bubbles. In this paper, a generalized equation for scattering cross section of spherical gas bubbles oscillating in liquids under acoustic excitation is pro…
BACKGROUND: Superparamagnetic iron oxide nanoparticles (SPIONs) are inorganic nanomaterials gaining strong clinical interest due to their increasing number of biological and medical applications. The stabilization of SPIONs in a biocompatible stable suspension (bioferrofluid) is generally achieved by an adequate polym…
Strain engineering, which employs biaxial misfit strain to deform the crystal structure, is a powerful tool to tune the physical behavior of epitaxial thin films. Here we show that a 10-nm-thick BiFeO${}_{3}$ film is uniaxially strained by (110)-oriented LaAlO${}_{3}$ substrate, which exhibits a monoclinic lattice wit…
A fundamental understanding of the intermolecular forces that bind polysaccharide chains together in cellulose is crucial for designing efficient methods to overcome the recalcitrance of lignocellulosic biomass to hydrolysis. Because the characteristic time and length scales for the degradation of cellulose by enzymat…
Short-chain-length medium-chain-length polyhydroxyalkanoate (SCL-MCL PHA) copolymers are promising as bio-plastics with properties ranging from thermoplastics to elastomers. In this study, the hybrid pathway for the biosynthesis of SCL-MCL PHA copolymers was established in recombinant Escherichia coli by co-expression…
Abstract Lavandin essential oil has been encapsulated in poly‐(ϵ‐caprolactone) (MW: 4000 g mol –1 ) by means of the particles from gas saturated solutions (PGSS) process. The influence of process conditions, i.e., pre‐expansion temperature and pressure, and oil/polymer mass ratio, on the morphology of particles and th…
An efficient finite element method to take account of the nonlinearity of the magnetic materials when analyzing three-dimensional eddy current problems is presented in this paper. The problem is formulated in terms of vector and scalar potentials approximated by edge and node based finite element basis functions. The…
The self-organization of ferroelectric columnar liquid crystals (FCLCs) is demonstrated. Columnar order is spontaneously formed in thin films made by the wet-process due to its liquid crystallinity. Electric-field application results in high optical quality and uniform spontaneous polarization. Such good processabilit…
ABSTRACT This work reports the study of the effect of chemical functionalization of carbon nanotubes on their dispersion in poly(lactic acid). The nanotubes were functionalized by the 1,3‐dipolar cycloaddition reaction, generating pyrrolidine groups at the nanotube surface. Further reaction of the pyrrolidine groups w…
The magnetocaloric effect (MCE) associated with the spin transitions of alternating longitudinal conical (ALC)-mixed conical (MC) and MC-ferrimagnetic (FIM) states in a Ba0.3Sr1.7Co2Fe12O22 single crystal has been investigated. For magnetic field directions applied along either the [120] or [001] directions, the cryst…
Aktiviert durch Licht: Photoaktivierbare („caged“) Depsipeptide werden durch Ligation exprimierter Proteine in das Rückgrat des Proteins SDF-1α eingebaut. Die gestörte Sekundärstruktur wird nach UV-Bestrahlung durch eine O→N-Acylumlagerung wiederhergestellt, und die chemotaktische Aktivität des Proteins wiedererlangt.…
We present very low temperature (0.15 K) scanning tunneling microscopy and spectroscopy experiments in the layered superconductor LaSb${}_{2}$. We obtain topographic microscopy images with surfaces showing hexagonal and square atomic size patterns, and observe in the tunneling conductance a superconducting gap. We fin…
In this study, two kinds of colloidal ternary semiconductor white light-emitting quantum dots (WQDs), Zn(0.5)Cd(0.5)S and Zn(0.8)Cd(0.2)S, are prepared and used as nanophosphors in a UV light-emitting diode (UV-LED) pumping device. When the weight ratio of Zn(0.5)Cd(0.5)S WQDs is 9.1 wt. % in silicone and the drive cu…
Polymer films that respond to a variety of stimuli are attractive candidates for location-specific guest molecule delivery. These systems release the guest molecules by polymer erosion; thus, these are mono-use systems. If a polymer film is used to disassemble amphiphilic assemblies containing sequestered guest molecu…
Ultra-small and functional copper nanoclusters (Cu NCs) have been extensively used in consumer technologies due to their superior properties. A simple and green way to prepare stable, water-soluble and near-infrared (NIR) Cu NCs by using a reducing agent was reported in this work. Reduced glutathione (GSH) worked as a…
An amphiphilic brush-linear diblock copolymer bearing a rigid difluorene moiety was synthesized, yielding a copolymer with a high thermal stability and excellent processability. The immiscibility of the blocks induced the formation of a variety of nanostructures, depending on the fabrication conditions, which differed…
