A lockstitch is formed by the interlacement of needle and bobbin threads. During high-speed sewing, needle thread is subjected to repeated tensile stresses, heat, bending, pressure, torsion, and wearing. Therefore, the mechanical properties of thread, which become altered during sewing, are very important for its perf…
The efficiency of a binder to link microcapsules on a textile surface depends on the compatibility of the different interfaces of the products involved in the coating process. The choice of a binder adapted to the microcapsules was determined in this study by the comparison of the surface energy components induced by…
This article discusses properties such as surface hardness, solvent uptake, cross-link density, diffusion coefficient, and tensile properties of vulcanized natural rubber (NR)/chitosan (CS) blends. Dicumyl peroxide was selected as a cross-linking agent. In the case of tensile properties, peroxide vulcanized blends sho…
The acid-base properties of cassiterite (alpha-SnO2) surfaces at 10-50 degrees C were studied using potentiometric titrations of powder suspensions in aqueous NaCl and RbCl media. The proton sorption isotherms exhibited common intersection points in the pH range of 4.0-4.5 under all conditions, and the magnitude of ch…
A well-defined potential gradient was introduced to the surface of indium tin oxide (ITO) during the seed-mediated synthesis of anisotropic gold nanoparticles (AuNPs) on substrates. Benefiting from this potential gradient, we found an evolution of particle morphology as a function of the position potential on ITO subs…
AFM is used to measure the surface forces and to image sodium poly(styrenesulfonate) (PSS) layers physisorbed from 1 M NaCl solution on different length scales within one experiment. Domains of PSS brushes coexist with flatly adsorbed PSS. For degree of polymerization N = 380, the brush area fraction is 6%. With incre…
Abstract Multiwalled carbon nanotube (MWNT)–polyurethane (PU) composites were obtained by an in situ polycondensation approach. The effects of the number of functional groups on the dispersion and mechanical properties were investigated. The results showed that the functionalized MWNTs had more advantages for improvin…
We performed a comparative study of the adsorption of an in vitro selected peptide on two different carbon surfaces: a flat graphene and a curved (0,15) nanotube. The sequence was selected from recent experiments, as the one giving the highest carbon affinity for carbon nanotubes. Rigid docking of the molecule on the…
In this Rapid Communication we experimentally probe the nonequilibrium breakdown of the quantum Hall state in monolayer graphene by injecting a high current density $(\ensuremath{\sim}1\text{ }\text{A}/\text{m})$. The measured critical currents for dissipationless transport in the vicinity of integer filling factors s…
We present a dual porosity CNT material with a seamless connection between highly porous aligned nanotubes and lowly porous closely packed nanotubes by using capillary action of liquids. Various approaches were developed to fabricate diverse structures using toothpicks, liquid thin films, bubbles, vapors, and superink…
Quantum Hall states that result from interaction induced lifting of the eightfold degeneracy of the zeroth Landau level in bilayer graphene are considered. We show that at even filling factors electric charge is injected into the system in the form of charge 2e Skyrmions. This is a rare example of binding of charges i…
A charge trapping layer can serve not only for designing multilevel nonvolatile memory but also for type conversion from p- to n-type and vice versa of carbon nanotube (CNT) channels. Type conversion from p- to n-type and vice versa for CNT field effect transistors can be realized by changing the polarity of trapped c…
S-CKD602 is a pegylated liposomal formulation of CKD-602. This study is the first to evaluate the factors affecting the high interpatient variability in the pharmacokinetic disposition of S-CKD602. S-CKD602 was administered intravenously (i.v.) every 3 weeks as part of a phase I study. Pharmacokinetics studies of the…
Multicarboxyl polymer-functionalized halloysite nanotubes (HNTs) were synthesized by controlled surface-initiated atom transfer radical polymerization (SI-ATRP) of methyl methacrylate (MMA) and/or hydroxyethyl methacrylate (HEMA) to form HNT-(PMMA- b -PHEMA) or HNT-PHEMA hybrids, followed by esterification of the hydr…

In this paper, we explored computationally the feasibility of modulating the bandgap in a single-wall BN nanotube (BNNT) upon noncovalent adsorption of organic molecules, combined with the application of a transverse electric field. Effects of analytes' physisorption on the surface of BNNTs regarding structural and el…
Abstract The aim of the present paper is to propose a phenomenological thermodynamically consistent 3D model for shape memory alloys (SMA) in the finite strain range. In particular, a model able to predict the main features of SMA materials, such as the superelastic and the shape‐memory effects, is proposed. The model…
Efficiently organizing molecular nonlinear optical (NLO) chromophores having large first-order hyperpolarizabilities (beta) into acentric microstructures for electro-optic (EO) applications represents a significant materials synthesis and processing challenge, in part due to interchromophore dipolar interactions that…
Sensors and devices made from single-walled carbon nanotubes (SWNTs) are most often electrically probed through metal leads contacting the semiconducting SWNTs (s-SWNTs). Contact barriers in general and Schottky barriers (SBs) in particular are usually obtained at a metal-semiconductor interface. The unique one-dimens…
This paper reports the design, fabrication technology, post-CMOS micromachining and characterization of CMOS-silicon-on-insulator (SOI)-microelectromechanical system (MEMS) transistors. The thermally isolated micromachined CMOS-SOI-MEMS transistor reported here is designed for uncooled infrared (IR) sensing and is dub…
