Two improved heat conduction models which reflect size and memory effects based on the CV model and the DPL model are proposed to simulate a one-dimensional thermal transport problem in a thin film induced by the ultra-fast laser. The results show that a thermal wave effect is appeared in heat conduction given by the…
Single walled carbon nanotubes (SWCNTs) are carbon based nanostructures with extraordinary electronical and mechanical properties. They are used in a wide range of applications, usually embedded in ...

The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space grou…
The present paper presents electronic structure and optical properties of the Ga x As x clusters for x= 10, 13, 15, 18, 20, 25 and 30 using density functional theory (DFT) method. The Ga-Ga bond length lies in range of 2.50-2.69 A 0 , the As-As bond length lies in range 2.58-2.62 A 0 and Ga-As bonds length is in range…

The ocean naturally contains uranium at a concentration of 3.3ng/g, thus offering thousands of years’ worth of nuclear fuel. Although ample uranium currently exists from terrestrial sources, the ability to recover seawater uranium would provide supply security for nuclear power generation, putting it on equal footing…

Organic nandots exhibit superior brightness and tunable optical properties. This presentation describes the development of small organic nanodots for biological imaging. Stimulated emission depletion (STED) imaging and Superresolution optical flunctuation imaging (SOFI) were demonstrated.

Generation of vacancies on plastic straining is enhanced by the presence of hydrogen. The high densities of vacancies and their clusters cause damage or deterioration of crystallinity preferentially in strain-concentrated areas, leading to the formation and propagation of cracks there. Good correlations have been foun…
La presente investigacion experimental se basa en la caracterizacion del material hibrido de matriz epoxica reforzado con capas de tejido plano estructurado de fibras de abaca y algodon en diferentes orientaciones y con variadas fracciones volumetricas, el fin del estudio es obtener la mejor caracterizacion del materi…
This cumulative thesis reports an experimental investigation of the stability of Fe-carbonates at mantle pressures and temperatures as well as analysis of an inclusion in diamond from the shallow lower mantle. The goal of the work is first to determine the stability regions of iron (or iron-bearing) carbonates inside…
Poly(ethylene glycol) (PEG) is widely used as a biomedical material because it possesses the highest level of biocompatibility among synthetic polymers. However, PEG is water-soluble and non-biodegradable. To provide biodegradable water-insoluble bulk materials possessing the biocompatibility of PEG, water-insoluble p…
An organotetrasulfide consists of a linear chain of four sulfur atoms that could accept up to 6 e− in reduction reactions, thus providing a promising high-capacity electrode material. Herein, we study three bis(aryl) tetrasulfides as cathode materials in lithium batteries. Each tetrasulfide exhibits two major voltage…
Composite nano-structures have many interesting properties and potential applications. For a molecule-nanoparticle (NP) composite array, its properties may strongly depend on the molecules on/between NPs. For instance, the resistance of NP composite film sensitively change with the length of surface molecules,[1,2] an…
I det här arbetet har tätningsmetoder för aluminiumhus undersökts. Arbetet avgränsades mot fordonsindustrin och statiska packningar. Examensarbetet tar upp flänskonstruktionens inver-kan på tätheten och packningen, packningstyper, ytjämnhetens inverkan på packningsmateri-al, porositet, relativ materialkostnad och fäst…
In this paper, we fabricated a TiO2 homogeneous hybrid structure for application in perovskite solar cells (PSCs) under ambient conditions. Under the standard air mass 1.5 global (AM 1.5G) illumination, PSCs based on homogeneous hybrid structure present a maximum power conversion efficiency of 5.39% which is higher th…
Fatigue crack growth rates (FCGR) were measured on a high-strength austenitic stainless steel in moist air (∼40% RH), moist hydrogen (<∼50 vppm water vapor), dry hydrogen and dry helium (both <3 vppm water vapor). FCGR was the same in moist air and moist hydrogen environments at 30 Hz and were higher than those in dry…
The fracture and fragmentation of materials subjected to high strain rate loading is a relevant topic for explosively driven metals, high velocity impacts and other high stress-rate and strain-rate loading events. Metals possess a microstructure whose details create variations in material properties such as strength.…
Residual stresses induced in the component by previous thermal/mechanical processes are compressive or tensile stresses having a zero resultant. In particular, they arise as consequence of thermo-mechanical processes (e.g. ring-rolling process), casting and heat treatments. When machining stressed components, volume r…
