The stabilized emulsions removal from the aqueous systems is supposed to be an issue as important as the free oil products recovery. This work was conducted to investigate the mechanisms of oil-in-water emulsions sorption in a non-woven oleophilic/hydrophobic material forced by the capillary suction pressure, and the…
Hydrophilicity/hydrophobicity of the surfaces of plasma-polymerized naphthalene film (Super Support Film, Nisshin EM Co. Ltd., Tokyo), carbon and formvar support films, and copper and nickel grids were quantitatively estimated by contact angles measured from diameters and heights of water droplets placed on various sp…
To investigate how the properties of model mixed metal oxide catalysts can be influenced by the choice of evaporating species during physical vapor deposition, we have compared MoO x on Al 2 O 3 /NiAl(110) prepared via an oxidic and a metallic precursor. In the former case, MoO x was prepared via direct deposition of…
In this contribution, we extend the phase separation abilities of magnetic levitation (MagLev), applying it to cocrystal systems. Most of these systems show incongruent solubility in solution. Crystallization from an equimolar mixture often leads to the crystallization of both cocrystal and coformer (one of the indivi…
This work demonstrates the use of a new Ag-NPs synthesized from reduction method of silver nitrate, for efficient ability and activity against various pathogenic bacteria. Here, this research is done in with the purpose of synthesizing silver nanoparticles while studying its antimicrobial properties on Gram positive a…
Electric transport coefficients such as carrier type, density, and mobility are the important physical parameters in designing functional devices. In this work, we report the study on the electric transport coefficients of the highly epitaxial LaBaCo2O5 + δ (LBCO) films, which were discussed as a function of electric…
Magnesium alloys are regarded as potential biodegradable load-bearing biomaterials for orthopedic applications due to their physico-chemical and biomechanical properties. However, their clinical applicability is restricted by their high degradation rate, which limits the physiological reconstruction of the neighbourin…
Changes in nominal composition of the perovskite (ABO3) solid solution Ba1-x(Zr,Pr)O3-δ and adjusted firing conditions at very high temperatures were used to induce structural changes involving site redistribution and frozen-in point defects, as revealed by Raman and photoluminescence spectroscopies. Complementary mag…
The randomly distributed dopant effects in nanocrystalline samaria‐doped ceria ( SDC ) interlayers were investigated by systematically varying the dopant distributions and grain‐boundary densities via post‐annealing process. Electrochemical analysis demonstrates that films having lower annealing or fabrication tempera…
Skin is a biological material the mechanical properties of which are dependent on the constituents from which it is assembled. Skin, the outer covering of animals is made up of collagen fibers arranged in more or less ordered arrays. Pufferfish skin provides a rigid framework to support the body contents and a flexibl…
A computational study of medium effect on solvation free energy, dipole moment, polarizability, hyperpolarizability and different molecular properties like chemical hardness & softness, chemical potential, electronegativity and electrophilicity index of metronidazole have been reported in this paper. Becke, 3-para…
Epitaxial indium tin oxide films have been grown on both LaAlO3 and yttria-stabilized zirconia substrates using RF magnetron sputtering. Electrolyte gating causes a large change in the film resistance that occurs immediately after the gate voltage is applied, and shows no hysteresis during the charging/discharging pro…
The purpose of this study was the development of novel, fast disintegrating, effervescent pellets by employing the direct pelletization technique as a single step process. In line with the Quality by Design (QbD) regulatory framework, statistical experimental design was extensively applied to correlate significant for…
본 연구의 목적은 마그네슘 생산을 위한 원료 물질로서 폐간수의 활용 가능성을 검토하는 것이다. 본 연구에서는 간수에 NaOH를 첨가하여 Mg 이온을 수산화마그네슘(<TEX>$Mg(OH)_2$</TEX>)으로 회수하는 침전법을 적용하였다. 간수에 용존되어 있는 Mg 이온은 NaOH 첨가량이 [NaOH]/[Mg] 몰비 2.70~2.75, pH 9.5~10.0에서 99% 이상이 제거되었다. 알칼리제로 첨가하는 NaOH 용액의 몰 농도는 Mg의 회수효율에 큰 영향을 미치지 않은 것으로 나타났다. 침전반응을 통해 생성되는 <TEX>$Mg(OH)_2$</TEX>의 입도는 주로…
Gold nanorods are an important kind of nanoparticles characterized by peculiar plasmonic properties. Despite their widespread use in nanotechnology, the synthetic methods for the preparation of gold nanorods are still not fully optimized. In this paper we describe a new, highly efficient, two-step protocol based on th…
We have studied a mixture of the twist-bend nemogenic dimer CB7CB with rod-like nematic molecules, which exhibits nematic (N) and twist-bend nematic (NTB) phases and a very large biphasic coexistence range. At the N-NTB transition, we observe the nucleation of highly anisometric NTB droplets which are very similar to…
Abstract We studied the phase-change behavior of Ge 2 Sb 2 Te 5 , which is a chalcogenide material widely used in phase-change memory, using precisely controlled electrical pulses to improve the efficiency of the switching operation. The electrical pulse is a critical parameter that supplies source energy to reversibl…
The advantages of photo polymerization methods compared to thermal techniques are: rapid cure reactions, low energy demands, solvent free requirements and room temperature use. In order to form a macromer, polycaprolactone (PCL) was cross-linked via ultraviolet power with 2-isocyanatoethyl methacrylate. Different meth…
This study investigates efficient optimization of heat fusion conditions between thermoplastics using molecular dynamics (MD) and a response surface method. The heat fusion process between polypropylene and polyethylene and the uniaxial elongation for evaluation of the interfacial bonding strength were modeled using c…
Two kinds of large-area ordered and highly tunable micro/submicro-nanopatterned surfaces in a complementary manner were successfully fabricated by elaborately combining block copolymer self-assembly and colloidal lithography. Employing a monolayer of polystyrene (PS) colloidal spheres assembled on top as etching mask,…
