We performed angle-resolved photoemission experiments on ${\mathrm{CaC}}_{6}$ and measured ${k}_{z}$-dependent electronic structures to investigate the interlayer states. The results reveal a spherical interlayer Fermi surface centered at the $\mathrm{\ensuremath{\Gamma}}$ point. We also find that the graphene-driven…
ABSTRACT The aim of this study is to synthesize flame‐retardant additive by using B/P/N and to investigate this additive's performance in the ultraviolet (UV) curable system. Therefore, in the first stage, borate ester (triethanolamine borate, TEAB) was synthesized by the reaction of boric acid and triethanolamine. In…
Different from other types of pipeline solids such as sand and iron carbonates, iron sulfide is semi-conductive and electrochemically reactive. This adds extra complexity to laboratory testing compared with inert deposits. Previous laboratory testing has shown that the corrosion rate under iron sulfide deposits can be…
ABSTRACT An amine‐terminated nucleophile Hexakis (4‐aminophenoxy) cyclotriphosphazene (HACP) was synthesized. Its chemical structure was identified by 1 H NMR and 31 P NMR. Novel monodispersed phosphazene‐containing microspheres with active amino groups on the surface have been successfully prepared through a one‐pot…
<p>The tropical Andes are undergoing climate changes that rival those occurring anywhere else on the planet, and are likely to have profound consequences for ecosystems. Paleolimnological investigations of remote mountain lakes can provide details of past environmental change, especially where monitoring data ar…
fibers that are available from various portions of the palm tree and to characterize its chemical and physical properties. Also the results were compared with other natural fibers.
The structural properties of Mo 2 Ga 2 C are simulated by first-principles under pressure. At 40 GPa, the axial compressibilities of [Formula: see text]- and [Formula: see text]-axes are 0.9763 and 0.9264, respectively, which are the known largest and smallest values in the [Formula: see text] compounds. A phase trans…
Nanoparticles (NP) of poly(lactic-co-glycolic acid) (PLGA) represent a promising biodegradable drug delivery system. We suggest here a two-step release system of PLGA nanoparticles with a pH-tunable polymeric shell, providing an initial pH-triggered step, releasing a membrane-toxic cationic compound. PLGA nanoparticle…
Flexible and optically anisotropic film with high transparency and optical transmission contrast in the visible and near infrared region was prepared based on aligned assembly of electrospun PVA nanofibers and simple post soaking and drying. The strategy for preparation of optically anisotropic film proposed here is s…
In the present paper, the stiffening effect of carbon nanotubes is quantitatively investigated by micromechanics methods. The Mori-Tanaka effective-field method is employed to calculate the effective elastic moduli of composites with aligned or randomly oriented straight nanotubes. In addition, the epoxy resin is modi…
After Fukushima accident and stress test recommended by IAEA for existing reactors, higher safety requirements are enforced upon nuclear power plants during design extension and severe accident conditions. Based on those arguments, Vietnam Government requests a lot of effective safety solutions, in designs proposed fo…
Microtubules (MTs) are fibrous and tube-like cell substructures exist in cytoplasm of cells which play a vital role in many cellular processes. Surface effects on the vibration of bioliquid MTs surrounded by cytoplasm is investigated in this study. The emphasis is placed on the effect of the motor protein motion on th…
We present results of precise measurements of the thermal and electrical transport in the optimally and overdoped $\mathrm{B}{\mathrm{a}}_{1\ensuremath{-}x}{\mathrm{K}}_{x}\mathrm{F}{\mathrm{e}}_{2}\mathrm{A}{\mathrm{s}}_{2}$ single crystals $(x=0.35,\phantom{\rule{0.16em}{0ex}}0.55,\phantom{\rule{0.16em}{0ex}}0.88)$…
The novelty of this study is presentation of an exact solution for prediction of postbuckling behavior of shear deformable micro- and nano-scale beams based on modified couple stress theory and using principle of minimum potential energy. Timoshenko and Reddy-Levinson beam theories are applied to consider the shear de…
The development of adhesives suitable for biomedical applications has been challenging given that these materials must exhibit sufficient adhesion strengths and biocompatibility. Biomimetic materials inspired by mussel adhesive proteins appear to contain many of the necessary characteristics for biomedical adhesives.…
In this work, the effect of extensional flow on the morphology of polystyrene-b-poly(ethylene-co-butylene)-b-polystyrene (SEBS) triblock copolymers and their clay-containing nanocomposites was evaluated. Four types of SEBS copolymers with different block compositions and cylindrical morphology were chosen to understan…
Purpose – The purpose of this paper is to investigate the inhibition effect of hydralazine hydrochloride as a corrosion inhibitor for mild steel in 1M HCl. The inhibition effect was studied at different temperatures, ranging from 303 to 333°K. Design/methodology/approach – The inhibition efficiency of hydralazine hydr…
This research is an exploratory experiment into sulfur concrete used not as a complete replacement of cement but as an additional material in percentage of the cement content. The aim of this research was to explore the possible appreciation of mechanical and physical properties of concrete containing sulfur with perc…
Purpose – This paper aims to study the corrosion behavior of D32 steel suffered to marine splash zone. Type D32 structural steel has good mechanical properties and is commonly used for offshore oil platform construction in China. To ensure the safety of marine steel structure, it is important to study the corrosion pr…
Isosorbide dinitrate-polyvinylpyrrolidone (ISDN-PVP) electrospinning fibers were formulated and explored as potentially sublingual membrane. The addition of polyethylene glycol (PEG) to the formulation improved flexibility and reduced fluffiness of the fiber mat. The scanning electron microscopy (SEM) demonstrated tha…
