Metal nanoparticles are now being exploited extensively in materials science, optics, chemistry, biology, and medicine because they interact strongly with visible and infrared light. ey have proven to be excellent optical nanoantennas, acting as robust radiation receivers, localizers, and emitters that can connect lig…
Films comprising metallic grains embedded in insulating matrices represent an important class of electronic materials. Conventional granular lms prepared by thermal evaporation, sputtering, chemical vapor deposition, electroless deposition, etc. have been extensively studied (Abeles et al. 1975). ey are typically diso…
As a sagging economy cruelled their electoral chances, right-wing parliamentarians and power-brokers in the South Australian Labor Party decided in late 2014 that it was time to ditch a once fiercely-defended point of policy. The party's remaining opposition to the nuclear fuel cycle would have to go.
Nanoparticles can be made from many di erent kinds of materials, including metals and semiconductors, with diameters ranging from as small as about 1 nm in diameter up to micrometers (Kwon and Hyeon 2008). When nanoparticles are smaller than 10 nm or so, they exhibit physical properties that di er from the bulk materi…

For the study and prediction of insulation properties of wood polymer-sand composite (WPSC) developed a mathematical model. It is established that the thermal diffusivity of the wood with a protective resin-sand coating, were comparable to the diffusivity of pure wood (ef-fective diffusivity 15-25 % higher). If the fi…
The present report documents ballistic impact tests on silicate ceramic layers with metal layers. The two layers of ceramic matrix composite (CMC) material specimens and Nickel-based steel alloy were positioned back-to-back. The CMC specimens were circular plates made of Keraman. The metal plates were of Inconel 718 (…
Structural properties of core-shell ferrite nanoparticles MFe2O4 (M = Mn and Co) and Mn-Zn ferrite nanoparticles are here investigated. The nanoparticles are synthesized by hydrothermal co-precipitation and are dispersed in acid medium thanks to an empirical surface treatment by ferric nitrate, which prevents the chem…

Gold nanoparticles (Au NPs) are being research extensively for various biomedical applications; their applicability arises from a unique set of optical and physical properties brought on by their nanoscale dimensions.1 Furthermore, facile and scalable synthetic and surface functionalization strategies for Au NPs make…
AbstractObjectivePolymer based materials used in the manufacture of extracorporeal circulation (ECC) circuit that is the main part of the heart lung machine used in cardiac surgery, poses the unavoidable inflammatory and coagulation reactions because of the contact with the tissue and biological fluids particularly th…
Telah dilakukan preparasi film elektrolit gel polimer kitosan-KI/I2 dengan metode solvent casting.Pada tahap awal, dilakukan kajian waktu pembentukan gel dan pengaruh jumlah KI terhadap sifat redoks dan konduktivitas ionik elektrolit gel kitosan.Elektrolit gel kitosan selanjutnya dibuat film disertai penambahan EG dan…
Partially implicit (or partially explicit) schemes, such as the convex splitting schemes (CSS in short), are among the most popular numerical schemes used in phase-field modeling. Using both theoretical analysis and numerical experiments, we demonstrate in this paper that all existing partially implicit schemes for ph…
This thesis introduces the high frequency, high pole count (HFHP) design for improving specific power density of electric machines for weight and/or volume sensitive applications. Although electric machine designs have reached a limit in terms of efficiency, reliability, and cost, newer applications such as in aviatio…
Ionization radiation is everywhere: cosmic rays, nuclear energy, medicine and etc. One of the main tasks during work with the ionization radiation – human safety. There are a lot of radiation protected clothes. To define their protective characteristics two way are possible: experimental and simulation. The numerical…
The investigation focused toward microstructure and electrochemical changes caused by proton on a passive film formed on the surface of stainless steel-304 in lower concentrated sulfuric acid solutions (exclusively 0.5, 1.0, 2.0, and 5.0 N concentrations). Dissociation rate of the proton in the acid was reduced due to…
Nous explorons les proprietes structurales de nanoparticules cœur-coquille, avec un cœur de ferrite MFe2O4 (M = Mn et Co) ou de ferrite mixte Mn-Zn. Ces nanoparticules sont obtenues par co-precipitation hydrothermique et sont dispersees en milieu acide par un traitement de surface empirique au nitrate ferrique, proteg…
Proper selection of high-performance materials is crucial in engineering. From the beginning of industrialization and with the advancement of technology, scientists have made enormous efforts for the development of materials which will satisfy specic technical requirements.
