Nanometer-sized metallic colloidal particles with plasmonic resonances in the visible range are widely investigated for their attractive optical properties as sensors, for imaging and cancer treatment. Their second-order nonlinear optical properties are remarkably high. In this work, silver colloidal solutions have be…
ABSTRACT The electrodeposition of polypyrrole films from aqueous surfactant solution through a two‐dimensional polystyrene template onto indium‐tin oxide substrate has been investigated. The polymer grows in the interstitial spaces of the self‐assembled polystyrene spheres, which were subsequently removed by dissoluti…
The compatibilization provided by maleic anhydride (MA) and 2-[2-(dimethylamino)-ethoxy] ethanol (DMAE) functionalized polyethylene for forming polyethylene-based nanocomposites was studied and compared. MA was grafted into PE by melt mixing to obtain PEgMA (compatibilizer 1), thereafter, PEgMA was reacted with DMAE a…
The iridescence green band and cyan tail of the wing on Papilio blumei butterfly were investigated. The bi-color phenomenon on the scales of butterfly wings was found and analyzed. The spectral change with thickness of chitin-air layers, width of air hole, total layer numbers and incident angle of light were simulated…
Abstract A BmSG-SWUl cell line was established from the silk gland tissues of newly hatched Bombyx mori L. larvae by performing primary cultures for 2 yr. The cell line was comprised of long and thin shuttle cells. The percentage of cells with the chromosome number 2n = 56 was 76.28%. Therefore, the cell line was cons…
Rhodanine derivatives of merocyanine dyes with residues of 1,3,3-trimethyl-3H-indole and 3-ethylbenzothiazoline have been found to possess two molecular forms in diluted solutions of polar solvents such as dimethylformamide, dimethyl sulfoxide, and N-methylpyrrolidinone. The first molecular form was observed to prevai…
Hyper Rayleigh and Hyper Raman spectra of neat water have been recorded in two different geometrical configurations where the incident fundamental beam is impinging on the cell at right angle from the collection direction and in retroreflection. A polarization analysis is also performed for the hyper Rayleigh experime…
Magnetic, magnetooptical and magnetotransport properties of Co50.3Fe20.3Ti5.6Ga23.8 thin films were studied for the as prepared as well as annealed samples. Measurements of transverse magnetooptical Kerr effect revealed that the spectral response of the films strongly depends on the structural ordering which can be ma…
AuNP effects on the oxidation reaction of [Ru(NH3)5pz](2+) with S2O8(2-) were studied. Experimental results show the effects produced by gold nanoparticles of different sizes, which are then discussed by using an approach based on the two-state model. Changes in the observed reactivity are explained by a change in the…
Thanks to progresses in material science and nanotechnologies, surfaces and thin films can now be structured at different scales. Photonics components take benefit of this possibility to fulfill still more and more complex functions. They are composed as well of organic as inorganic materials, dielectric, semiconducto…
Low-density lipoproteins (LDL) and high-density lipoproteins (HDL) are attractive natural occurring vehicles for drug delivery and targeting to cancer tissues. The capacity of both types of the lipoproteins to bind hydrophobic drugs and their functionality as drug carriers have been examined in several studies and it…
Gas Coller merupakan alat yang digunakan untuk menurunkan temperature gas yang diperoleh dari dalam bumi agar dapat dimanfaatkan sesuai dengan spesifikasi yang direncanakan. Gas Coller tersebut berupa alat penukar panas yang dibentuk dari sebuah tabung silindris yang diberi tutup di kedua ujungnya. Penyambungan tabung…
As more and more uranium mining and metallurgy facilities are facing decommissioning, studies on environmental impacts of uranium mill tailings are given much attention. It has become an important part of environmental impact assessment of decommissioning uranium mining and metallurgy facilities. On the basis of many…
The title complex was isolated as a red solid from the reaction of 4-(salicylaldiminato)antipyrine, HL, and cobalt (II) acetate in ethanol. The complex has been characterized by elemental analysis, FTIR, UV-Vis, and X-ray single crystal diffraction. Two crystallographically different cationic units, A and B, of the ti…
There are several vacant channels for diagnosis, RF heating, etc. through the shielding structure in fusion reactors. Some of them consist of dogleg ducts, and the streaming effect has not been experimentally investigated yet. The present work was conducted to study the behavior of neutrons streaming through the ducts…
Radiation field analysis in nuclear power plant (NPP) was performed by using Monte Carlo simulation against whole containment building. In this work, the neutron energy spectra were calculated in the high-level radiation field of Kori Unit 1 in Korea, which is to be a basis of dose assessment for NPP workers. The Mont…
From high field electron spin resonance measurements in illuminating polarized light, we have revealed the existence of electromagnon, i.e., magnon excitation by oscillatory electric fields of light, in the field-induced 1/5-plateau phase of the triangular lattice antiferromagnet ${\mathrm{CuFeO}}_{2}$. We indicate th…
Solid compounds of pyridin-2-ylaminomethylene meldrun’s acid derivatives was synthesized and characterized by nuclear magnetic resonance (1H and 13C NMR), mass spectrometry (MS), Infrared spectroscopy (FTIR), simultaneous thermogravimetry-differential thermal analysis (TG-DTA) and differential scanning calorimetry (DS…
Three-dimensional (3D) topological insulators (TI) are a new state of quantum matter in which surface states reside in the bulk insulating energy bandgap and are protected by time-reversal symmetry. It is possible to create an energy bandgap as a consequence of the interaction between the conduction band and valence b…
Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related death worldwide, particularly in regions where chronic Hepatitis B and C infections are common. Nanoparticle assemblies that incorporate high-affinity aptamers which specifically bind malignant hepatocellular carcinoma cells could be useful…
