The variations in material composition, phase and structure can provide a useful tool for tuning emission colour, but the controlling of the emission colour in a material, with a composition fixed, remains to be a daunting challenge. In this work, we systematically study the luminescence selective output characteristi…
PMMA chains were confined at a layered material (organically modified MgAl layered double hydroxides) surface, which formed the interfacial layer between nanoparticles and the polymer matrix.
Using the first-principles density functional theory (DFT) calculations, we study the effects of Co adatom on the electronic and magnetic properties of monolayer WS2. The calculations show that, for the high symmetry adsorption sites (Tw, H and Ts) on the surface of monolayer WS2, Co atom prefers Tw site. The p-d hybr…

Quantum model of joule heating relies on electron-phonon scattering in the high field region (hot side contact), which locally increases phonon population and forms hot spots. Hot spots in the high field region are known to suffer carrier transport. In this work, for the first time we report remote joule heating of th…
Besar arus listrik dalam proses pengelasan sangat berpengaruh dalam menentukan kualitas hasil pengelasan ditinjau dari kekuatannya dan temperatur/suhu merupakan faktor yang sangat berpengaruh pada ketangguhan suatu material dimana semakin rendah temperatur material maka semakin rendah pula ketangguhannya mulai dari ra…

The purpose of this research is to elucidate quantitatively the degree of performance improvement in solid oxide fuel cells (SOFCs) which use methane as a fuel by introducing anode off-gas recycle (AGR) through experiments and simulation. In the experiments, power generation characteristics of a commercially available…
自然海水中で自然生起・進展するすきま腐食の実態を明らかにすることは非常に重要な課題である．今回，SUS304ステンレス鋼の金属／石英ガラスすきま部のすきま腐食挙動の動的観察を自然海水中で764時間行った．試験中，自然電位を連続的に測定し，試験後腐食深さ分布測定をおこなった．その結果，1）SUS304の自然電位は約600mV付近までバイオフィルム生成の影響で貴化し，浸漬後331.5hで電位の卑化が起こり，すきま部の縁下近傍にすきま腐食が自然生起した．2）その後，時間経過とともに徐々にすきま内部に二次元的（面積的）にすきま腐食は進展してゆくものの，深さ方向への進展はなく，すきま腐食発生後，約100h経過した時点で，特定部位が三次元的（…

We investigated the suppression mechanism of strain-age-hardening in a ferritic carbon steel associated with hydrogen uptake. We considered hydrogen-related three factors suppressing the strain aging: 1) solution softening, for instance, arising from a reduction in Peierls potential of screw dislocations and a change…
A three-dimensional self-assembly strategy for constructing graphene oxide hybrid supramolecular hydrogel with regular porous structure was developed.
Interlaced yarn alternately has tangling parts and opening ones. It is produced by hitting steadily air with a fixed high-pressure on the multi-filament yarn, which runs at a fixed speed, using the air injection equipment called an interlacer. In order to clarify a mechanism of this production, we used a yarn construc…
This study first reveals a new type of linearly growing polyelectrolyte multilayer buildup mechanism, when one of the components (PAH) induces the self-assembly of the oppositely charged component (flagellin), creating a filamentous nanostructured coating.
The monolayer MoS 2 thin film was deposited directly on quartz substrate by chemical vapor deposition (CVD) approach using MoO 3 and sulfur powders as reactants. Raman spectroscopic and photoluminescence (PL) spectroscopic analyses were conducted to evaluate the structural and optical property of the grown MoS 2 thin…
Abatement of negative impact of leather industry on the environment is associated with scientifically grounded use of chemical materials and raw materials, with the development of low-toxic and low-waste technologies. A solution of this problem can be development and implementation of pre-tanning and tanning processes…
. In this paper we consider the possibility of replacing the diffraction axicon and the conical axicon on the gradient lens with a linear variation of the refractive index. Analytically and numerically using the finite-difference timedomain method we performed a comparative study of the Gaussian beam diffraction on di…
/PTB7. This work demonstrates that the co-doping of robust rare earth ions with different unique functions can widen the harvesting range of the solar spectrum, boost electron transfer rate and eventually strengthen device performance, without complicated interfacial and structural engineering.
