Biomedical titanium alloys with Young's moduli close to that of cortical bone, i.e., low Young's modulus titanium alloys, are receiving extensive attentions because of their potential in preventing stress shielding, which usually leads to bone resorption and poor bone remodeling, when implants made of their alloys are…
Single- and few-layer MoS2 nanoflowers are first discovered to have a piezo-catalyst effect, exhibiting an ultra-high degradation activity in the dark by introducing external mechanical strains. The degradation ratio of the Rhodamine-B dye solution reaches 93% within 60 s under ultrasonic-wave assistance in the dark.
FENOMENA KOROSI ZIRKALOY-2 DAN ZIRKALOY-4 DALAM MEDIA LARUTAN NaCl SECARA ELEKTROKIMIA. Zirkaloy-2 dan zirkaloy-4 digunakan sebagai bahan kelongsong pada elemen bahan bakar reaktor daya BWR (Boiling Water Reactor) dan PWR (Pressurized Water Reactor). Selama penggunaanya dalam kolam penyimpanan bahan bakar bekas kemung…
PEMBUATAN SUMBER RADIASI GAMMA ISOTOP 137Cs DENGAN AKTIVITAS 20 mCi DARI PEB U3Si2-Al PASCA IRADIASI DALAM CONTAINER STAINLESS STEEL. Kegiatan uji pasca iradiasi pelat elemen bakar (PEB) U3Si2-Al banyak menghasilkan larutan dengan keaktifan yang sangat tinggi. Larutan tersebut mengandung isotop 137Cs, uranium serta tr…
Cachaça is the second most widely consumed alcoholic beverage in Brazil, obtained by distillation of sugarcane wine, having its quality affected by the raw material, fermentation conditions and productive process. With the growing demand of the consumer market for quality cachaça, the search for the improvement in rel…
We study Raman scattering in molecular media by applying two laser fields in a two-photon resonance with vibrational transition. The role of rotational levels has been investigated. It is shown that the molecular vibrational coherence strongly depends on the effect of coherent population trapping for rotational levels…
Rapid development in nanomaterial synthesis and functionalization has led to advanced studies in actuation and manipulation of cellular functions for biomedical applications. Often these actuation techniques employ externally applied magnetic fields to manipulate magnetic nanomaterials inside cell bodies in order to d…
The interaction effect of photodisruption, which is used for dissection of biological tissue with fs-laser pulses, has been intensively studied inside water as prevalent sample medium. In this case, the single effect is highly reproducible and, hence, the method of time-resolved photography is sufficiently applicable.…
Nanoclays were prepared using supercritical carbon dioxide (scCO 2 ) as a medium, and then blended with polyethylene terephthalate (PET) via conventional melt blending processing. The structure and morphology of nanoclays were investigated using wide‐angle X‐ray diffraction (WAXD) and scanning electron microscopy (SEM…
Malonyl-CoA decarboxylase (MCD) can control the level of malonyl-CoA in cell through the decarboxylation of malonyl-CoA to acetyl-CoA, and plays an essential role in regulating fatty acid metabolism, thus it is a potential target for drug discovery. However, the interactions of MCD with CoA derivatives are not well un…
An easy pathway to synthesize a variety of cupric oxide (CuO) nanoshapes by a one-step wet chemical method is reported. CuO nanoparticles and nanorods were obtained from CuCl2 in a mixture of water and DMSO in the absence of a base at room temperature. 1-D CuO nanostructures resembling wires inside tubes, or nanopea p…
Manufacturing of the superconducting poloidal field (PF) coils in the JT-60SA tokamak is in progress. Recently, three equilibrium field (EF) coils, i.e., EF4, EF5, and EF6, intended for installation beneath the TF coils, were already completed with precision and temporarily installed on the cryostat base in the torus…
Novel chalcogenide glass-based fiber opens up the mid-infrared (MIR) range for real-time monitoring and control in medical diagnostics and chemical processing. Fibers with long wavelength cut-off are of interest here. Sulfide, selenide and telluride based chalcogenide glass are candidates, but there are differences in…
Based on first principles density functional theory, structural, electronic, and optical properties of poly (3‐thiophene boronic acid) organic polymer have been calculated. It consist of positively charged pending boronic acid and negatively charged polymerized thiophene backbone which have anionic polymerization as i…
Conjugation of oligonucleotides or aptamers and their corresponding analytes onto plasmonic nanoparticles mediates the formation of nanoparticle assemblies: molecularly bound bundles of nanoparticles which cause a measurable change in the colloid’s optical properties. Here, we present further optimization of a “SERS o…
ABSTRACT The effect of a calcium stearate (CaSt2) additive on the melt processability and flame retardancy of polyethersulfone (PES) was studied. Measurements of the viscosity of PES and its composites showed a marked decrease in viscosity with increase in the fraction of CaSt2 additive. About 40% reduction in viscosi…
This work presents the results of synthesis and characterization of polycrystalline [Formula: see text]-type Bi2S3thin films. The films were grown through a chemical reaction from co-evaporation of their precursor elements in a soda-lime glass substrate. The effect of the experimental conditions on the optical, morpho…
We describe the optical emission and the carrier dynamics of an ensemble of self-assembled GaAs quantum dots embedded in GaP(001). The QD formation is driven by the 3.6% lattice mismatch between GaAs and GaP in the Stranski-Krastanow mode after deposition of more than 1.2 monolayers of GaAs. The quantum dots have an a…
SiC nanoparticles by carbothermal reduction show promising properties in terms of second harmonic and multiphoton excited luminescence. In particular, we estimate a nonlinear efficiency < d < = 17 pm/V, as obtained by Hyper Rayleigh Scattering. We also present results of cell labelling to demonstrate the potential use…
We report on local magnetization measurements showing the presence of an unexpectedly strong transverse Meissner effect in the superconducting ${\mathrm{Cu}}_{x}{\mathrm{TiSe}}_{2}$ single crystals. We show that for tilted magnetic fields $({H}_{a})$ vortices remain aligned with the $ab$ planes up to field ${H}_{k}\en…
