Using unique experimental setups allowing spherical neutron polarimetry (SNP) and unpolarized neutron diffraction at pressure up to 8 GPa, this collaboration of authors from Japan, France, and the UK investigates pressure- and magnetic field induced gigantic ferroelectricity in multiferroic DyMnO${}_{3}$. This work re…
Telah dilakukan pendopingan aluminium pada ZnO untuk meningkatkan efisiensi Dye Sensitized Solar Cells (DSSC). Sintesis lapisan ZnO dilakukan menggunakan metode Liquid Phase Deposition (LPD) pada suhu 80 oC selama 10 jam dengan variasi doping aluminium sebesar 0%; 1,0%; 1,5%; 2,0%; dan 2,5%. Sampel dikarakterisasi men…
Abstract The key step for the adsorption‐desorption engineering process is the reversible in‐situ desorption of the adsorbent without VOCs (volatile organic compounds) accumulation. Our previous results show that the mesoporous silica gel performs well in adsorbing and desorbing the VOCs due to their capillary condens…
We investigate the longitudinal conductance of a disordered three-dimensional (3D) quantum Hall system within a tight-binding lattice model using numerical Thouless conductance calculations. For the bulk, we confirm that the mobility edges are independent of the propagating directions in this anisotropic system. As di…
Ion partitioning behavior in electrolyte solutions plays an important role in drug delivery and therapeutics, protein folding, materials science, filtration, and energy applications such as supercapacitors. Here, we show that the segregation of ions in solutions also plays an important role in the exfoliation of natur…
Porous polymers are of great interest in potential energy storage and environmental remediation applications. However, traditional fabrication methods are either time-consuming or energy-consuming and deteriorate the mechanical strength of polymer materials. In this study, polymerization-induced phase separation was u…
Abstract A test gas generation system for complex gas mixtures designed to mimic real industrial gas matrices with traces raging from low pptv to high ppmv level and minor and main components ranging from low to high percentage levels with variable relative humidity levels (0–80 % RH) is presented. It combines differe…
We report on the effect of Carbon insertion on the microstructure and magnetic properties of nanocrystalline Pr2Co7Cx([Formula: see text]). The Pr2Co7Cx were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and physical property measurement system (PPMS9) Quantum Design. Mean field theo…
The extraction of hexavalent actinides An(VI) by tri-butyl phosphate (TBP) was investigated by electronic absorption and vibrational spectroscopies. Through a series of spectral subtractions, vibrational spectra associated with TBP, TBP–HNO3 adducts, and An(VI)–TBP complexes could be isolated. Investigation of U(VI) e…
Abstract The highly active spherical hybrid catalysts with diameters of 3–8 μm for robust selective CO2 photoreduction and hydrogen production by switching solvent, CoP/(i)s‐SBA‐15 and CoP/(o)s‐SBA‐15, were in situ synthesized for the first time by incorporating CoP nanoparticles on the interior and outside of the sph…
– Microcapsules technology for smart materials application were developed recently years. One of the smart materials was self-healing coating. The microcapsules containing healing agent are dispersed into a polymeric matrix to form self-healing composite. Additionally, the microcapsules might be incorporated into pain…
Perovskite solar cells (PSCs) fabricated on transparent polymer substrates are considered to be one of the most disruptive competitors in the solar cell industry for their favorable traits, including high efficiency, flexibility, light weight, portability, and compatibility with curved surfaces. More importantly, PSCs…
It is important to enhance penetration depth of nanomedicine and realise rapid drug release simultaneously at targeted tumour for improving anti-tumour efficiency of chemotherapeutic drugs. This project employed sodium alginate (Alg) as matrix material, to establish tumour-responsive nanogels with particle size conver…
We theoretically analyze the effect of the inversion symmetry breaking on the structure of the impurity molecular states in Weyl metals. We show that for the case of a highly noncentrosymmetric Weyl metallic host, the standard picture of the alternating bonding and antibonding orbitals breaks down, and a qualitatively…

Abstract The effects of nitrogen incorporation by high-dose ion implantation in epitaxial gadolinium oxide (Gd2O3) films on Si (111) followed by annealing have been investigated. The nitrogen content in the oxide layer was changed by altering the implantation dose. The presence of nitrogen incorporation on the Gd2O3 l…
A compact and simple in design device (friction machine) for testing materials for friction and wear is developed. The device is intended for determination of the wear resistance and friction coefficient of structural, frictional and antifriction materials, as well as the tribological characteristics of lubricants. Th…
Scattering resonance of medium mass nuclides leads complex spectrum in the fast reactor, which requires thousands of energy groups in the spectrum calculation. When the broad-group cross sections are collapsed, reaction rate cannot be completely conserved. To eliminate the error from energy collapsing, the Super-homog…
This study investigated the crystallization position and formation mechanism of globular crystals at the center area in the thickness direction of aluminum alloy strips cast by a high-speed twin roll caster. Twin roll casters for single strips and clad strips were used, as well as twin roll casters equipped with a coo…
Abstract Hairy nanoparticles (HNPs) constitute a class of hybrid nanocomposites that are resistant to aggregation and agglomeration, although the green, large‐scale synthesis of HNPs remains a challenge. In this work, 25 nm‐diameter silica‐core HNPs with a poly(methyl methacrylate) (PMMA) shell were synthesized using…
