Erbium doped zinc phosphate glass embedded with natural Fe3O4 nanoparticles having a composition of (69-x)P2O5 - 30ZnO - 1Er2O3 – (x)Fe3O4, where x = 0, 0.5, 1.0, 1.5, 2.0 mol% has successfully been prepared by melt quenching technique. It was found that the color of the glass varies from pink (without natural Fe3O4 n…
Adaptive micro-lenses enable the design of very compact optical systems with tunable imaging properties. Conventional adaptive micro-lenses suffer from substantial spherical aberration that compromises the optical performance of the system. Here, we introduce a novel concept of liquid micro-lenses with superior imagin…
In this study, banana fibers have been used as reinforcement in epoxy resins to produce compressed banana fiber composite. The aim of this study is to compare the mechanical and physical properties of the banana fiber composite according to the portions of the banana stem fiber. The method used in fabrication of banan…

본 연구에서는 기체 분리를 위한 제올라이트 세라믹 멤브레인 제조에 적합한 입자크기와 형상을 갖춘 나노크기의 제올라이트를 TPAOH : SiO2 : H2O의 적합한 조성으로 합성하였으며 그 특성을 분석하였다. 실리카 원으로는 TEOS,LUDOX AS-40, CAB-O-SIL을 사용하고, TPAOH와 함께 출발물질로 하여 특정 조성의 TPAOH, SiO2, H2O gel을 합성하고, NaH2PO4 및 다양한 산 염기를 결정화 촉진제로 사용하였다. 합성시간을 단축할 수 있는 방법의 일환으로 저온에서2단계 온도 변화법을 적용한 수열합성법으로 TPA-Silicalite-1을…
Polycaprolactone (PCL) is a polyester, frequently used in bio-based polymer systems. We prepared composites of PCL and three different types of TiO2- based nanoparticles (TiX). This contribution is aimed at detailed characterization of morphology of PCL/TiX systems.
Coated cemented carbide inserts were applied in up- and down-milling stainless steel for monitoring the tool wear at repetitive cutting loads of various magnitudes and durations. Via impact tests with adjustable force signal characteristics, the applied loads can simulate the developed ones in milling when the cutting…
Paclitaxel, a natural occurring diterpene alkaloid, is a relatively new antineoplastic agent for clinical treatment of breast, lung, ovarian, head and neck cancers. Anti-cancer agents in the cancer therapy cause a large number of toxic side effects which require a reduced dosage of chemotherapeutic agents or occasiona…
For (7Li2S)x(P2S5)100–x glasses (x = 50, 60, and 70) and 7Li7P3S11 metastable crystal, time-of-flight neutron diffraction and synchrotron X-ray diffraction experiments were performed, and three-dimensional structures and conduction pathways of lithium ions were studied using the reverse Monte Carlo (RMC) modeling and…
Here, we review the various methods for the preparation of vanadium dioxide (VO2) films and nanowires, and their potential applications to the sensors such as gas sensor, strain sensor, and temperature sensor. VO2 is an interesting material on account of its easily accessible and sharp Mott metal-insulator transition…
PLLA telah banyak digunakan dalam bidang medis. PLLA berpori sangat potensial untuk rekonstruksi rekayasa jaringan vascular graft. PLLA yang bersifat hidrofobik dan terjadinya penurunan pH saat terdegradasi yang menyebabkan inflamasi mengharuskan adanya modifikasi pada permukaan PLLA, salah satunya dengan melapiskan k…

We investigate the doping dependence of the magnetic excitations in the two-superconducting-dome system LaFeAsO1−xDx. Using inelastic neutron scattering, spin fluctuations at different wave numbers were observed under both superconducting domes around x =0.1 and 0.4 but vanished at x =0.2 corresponding to the Tc valle…

V diplomski nalogi se ukvarjamo z energetsko analizo izbranih gradbenih proizvodov, in sicer toplotnoizolacijskih materialov. V zadnjih letih je ucinkovita raba energije izjemno aktualna, s tem pa tudi tema sanacije energetsko potratnih stavb v Sloveniji. Doslej je bilo najvec raziskav izvedenih na podrocju financnih…
Presently, ZnO nanostructures have found an intensive interest due to its wide applications in solar cells, UV lasers, nanogenerators, light emitting diodes, piezoelectronics, gas sensors and field emission devices. In this work, ZnO nanostructure is grown and characterized by field emission scanning electron microsco…
We review the small-angle neutron scattering (SANS) instruments, prepared at JRR-3, Tokai, Japan. Conventional pin-hole type SANS instruments (SANS-J-II and SANS-U) were recently reinforced by using focusing lens in order to detect ultra-small-angle neutron scattering (USANS) appearing at q=10-4Å-1, where q is a magni…
The structure of cured phenolic resins prepared by compression molding of a deuterated phenolic resin oligomer and nondeuterated hexamethylenetetramine as a curing agent was investigated using complementary small-angle neutron and X-ray scattering techniques. The results indicate that (i) cross-links are randomly dist…
Groundwater is one of the world’s most important and fragile sources of drinking water. Groundwater is opposite to surface water well protected from contaminants and external influences. A bigger challenge is how to remove a contaminant, if it spreads to the groundwater aquifer. Contaminated groundwater is a worldwide…
