Solution‐processable microporous polymers are promising materials for CO 2 capture because of their low synthetic cost and high processability. In this work, we for the first time systematically evaluate the feasibility of two microporous polymers, namely PIM‐1 and its hydrolyzed form hPIM‐1, as adsorbent materials fo…
Abstract Herein, ene‐functionalized dopamine is first coated onto a polyether sulfone membrane surface to introduce double bonds as anchoring sites for hydrogel film. Then, a hydrogel film is synthesized and simultaneously attached onto the membrane via photoinduced crosslinking copolymerization of N ‐isopropylacrylam…
This work attempts to clarify the potentials of hybrid model based on least‐squares support vector machine (LS‐SVM) and a novel meta‐heuristic algorithm called Grey Wolf optimiser (GWO) in high‐voltage applications, considering several kernel functions. The selection of the suitable kernel function and its parameters…
In this study, the tracer fiber method was used to determine the accelerated point distribution in both the break draft and main drafting zone of the drawing frame with varying different draft parameters. Viscose, cotton, and polyester slivers were used respectively. For the different parameters, the tracer fibers of…
The local magnetic anisotropy of R ions in R2Fe14B (R = Dy, Ho) systems is studied based on a microscopic effective spin model constructed from the information obtained by using first-principles calculations. By taking into account up to 6-th order crystal electric field parameters, the model satisfactory describes th…
We investigated the growth of boron-doped few-layer graphene on α-Al2O3 (0001) substrates by molecular beam epitaxy using two different growth approaches: one where boron was provided during the entire graphene synthesis and the second where boron was provided only during the second half of the graphene growth run. El…
In this study, graphene oxide (GO) is chemically reacted with sodium borohydride (NaBH4) to form reduced graphene oxide (rGO). rGO, polycarbazole (PCz)/rGO and PCz/nanoclay/rGO materials were obtained by chemical polymerisation method. These three materials were characterised by Fourier-transform infra-red spectroscop…
Abstract The optical characteristics of MoS 2 monolayers on SiO 2 /Si substrates with an SiO 2 thickness ranging from 40 to 130 nm are investigated. The measured Raman and optical reflection spectra of the MoS 2 monolayers vary considerably depending on the SiO 2 thickness. The Raman peak intensity of the MoS 2 monola…
Abstract Chiral nematic liquid crystals are stimuli‐responsive soft materials that can self‐organize into complex chiral superstructures. Control and manipulation of the chiral ordering is essential in the development of functional electro‐optic devices. Here, the effect of surface topography is combined with an appli…
BACKGROUND: ECMO is a therapeutic act with a high risk of exposure to diethylhexylphthalate (DEHP), plasticizer from PVC tubings. The replacement of this plasticizer with alternative compounds is recommended but the risks associated with the use of new plasticizers have not been evaluated in ECMO situations. METHODS:…
A prototype of constant temperature drying rate (DRCT) tester (CTDRT) was built to evaluate the DRCT of fabrics. The sample platform is kept at constant temperature and was placed on the balance. The platform temperature is adjustable to simulate different skin temperatures. A heater was placed underneath the sample p…
We present a combined theoretical and experimental study on the electron transport characteristics across several representative interface structures found in back-end-of-line interconnect stacks for advanced semiconductor manufacturing: Cu/Ta(N)/Co/Cu and Cu/Ta(N)/Ru/Cu. In particular, we evaluate the impact of repla…
We study optical transitions in spatially indirect excitons in transition metal dichalcogenide (TMDC) heterostructures separated by an integer number of hexagonal boron nitride (h-BN) monolayers. By solving the Schrödinger equation with the Keldysh potential for a spatially indirect exciton, we obtain eigenfunctions a…
Siliceous mesoporous MCM-41 materials were synthesized under ultrasonic treatment from 0.5 to 3 h. The obtained U-[Si]MCM-41 catalysts were applied in the Beckmann rearrangement of cyclohexanone oxime (CHO) to ε-caprolactam (CPL). The ultrasonic treatment can increase the pore wall thickness, while the density of surf…
The Nuclear Waste Management Organization is evaluating the safety and feasibility of the permanent disposal of used nuclear fuel in a deep geological repository. Their current design concept utilises copper-coated steel used fuel containers to isolate the waste from the environment. Immediately following repository c…
Generation of visible photons by upconverting materials under excitation by the near-infrared part of sunlight is very attractive for complete utilization of solar energy. Visible upconversion luminescence is efficiently generated in BaCl 2:Ln 3+ (Ho 3+ or Pr 3+ ) particles via excitation with broad band near-infrared…
We discuss neutral and charged complexes (biexcitons and trions) formed by indirect excitons in layered quasi-two-dimensional semiconductor heterostructures. Indirect excitons---long-lived neutral Coulomb-bound pairs of electrons and holes of different layers---have been known for semiconductor coupled quantum wells a…
Hydrophobic polymers, for their favorable mechanical properties, are a popular choice as permanent bioimplants. These materials remain absolutely bioinert for years, but throw up challenges when it comes to fast integration with healthy tissue. Addressing this, herein, we present a surface-modification technique of co…
nanoparticles were pre-prepared successfully, and they appeared to be homogeneously dispersed in nanofibers via electrospinning. During the sorption of Hg(II) ions, the significant fluorescence signals of nanofibers gradually declined and exhibited a good linear relationship with cumulative adsorption capacity, which…
ABSTRACT This work evaluates the influence of two types of carbonaceous fillers, carbon black (CB) and carbon nanotubes (CNTs), on the electrical, electromagnetic, and rheological properties of composites based on poly(acrylonitrile‐ co ‐butadiene‐ co ‐styrene) (ABS) prepared by the melt mixing. Electrical conductivit…
