SnO2 is an important functional material having a wide range of applications in gas sensors and optoelectronic devices. There is a great interest for finding new costeffective and straight-forward methods for production of these particles. In this research, hydrogel thermal decomposition method (HTDM) is used for production of high purity SnO2nano-particles. Cost effective reactants and green routs of production are the advantages of polysaccharide based hydrogel as starting material for this method. Visual observations indicated that there is very little tendency for agglomeration in th

For everyday cycling, one needs to carry rainproof clothing just for the case of unexpected downpours. In the present research, we present a concept for a helmet which is automatically rainproof when the rain starts. When the sun comes out, the helmet is breathable again even before it completely dries up. This functionality is provided by active hydrogel meshes. Hydrogel meshes offer great advantages due to their ability to change the aperture size with swelling and deswelling. In our current work, we present the design and modeling steps for hydrogel-layered active meshes which use (i) swell

Polyelectrolyte hydrogels are viscoelastic electroactive polymers which respond to external physical or chemical stimuli by a reversible volume phase transition. Novel fabrication methods allow the creation of hydrogel layer composites in which each layer shows a different sensitivity (e.g. to a different stimulus). This offers new opportunities, for example, in the design of new microsensors, microactuators and microfluidic devices as well as for high-selective membranes and target-specific drug delivery systems. Since only few research groups numerically investigated the transport mechanisms

This unique, but welldocumented, adverse effect is termed medication-related osteonecrosis of the jaws (MRONJ).

Ionic hydrogels belong to the class of polyelectrolyte gels or ionic gels.

In engineering, materials are chosen from databases: Engineers orient on specific parameters such as Young's modulus, yield stress or thermal expansion coefficients for a desired application. For hydrogels, the choice of materials is rather tedious since no generalized material parameters are currently available to quantify the swelling behavior. The normalization of swelling, which we present in the current work, allows an easy comparison of different hydrogel materials. Thus, for a specific application like a sensor or an actuator, an adequate material can be chosen. In the current work, we

Fossil fuels constitute a significant fraction of the world’s energy demand. The burning of fossil fuels emits huge amounts of carbon dioxide into the atmosphere. Therefore, the limited availability of fossil fuel resources and the environmental impact of their use require a change to alternative energy sources or carriers (such as hydrogen) in the foreseeable future. The development of methods to mitigate carbon dioxide emission into the atmosphere is equally important. Hence, extensive research has been carried out on the development of cost-effective technologies for carbon dioxide capture

This theoretical framework is based on the momentum-space Lippmann-Schwinger equation, an integral form of the Schrodinger equation. Although the approach has been highly successful in its application to atomic scattering theory, computing numerical solutions is inherently difficult because the momentum-space LS equation is a singular integral equation.

Streszczenie:

In the present study the interaction of Hydrogen Sulfide with inside and outside single-wall carbon nanotube of (5,0) and (5,5) was investigated. This study was conducted using DFT at B3LYP/6-31G* level of theory. Computational calculations were performed in the gaseous phase in Gaussian 09. The geometry of all molecules under investigation was determined by optimizing all geometrical variables without any symmetry constraints. The harmonic frequencies were computed from analytical derivatives for all species in order to define the minimum-energy structures. The adsorption energies, the t

L'hydrogène produit à partir de sources renouvelables et utilisé dans les piles à combustible pour diverses applications, tant mobiles que stationnaires, constitue un vecteur énergétique très prometteur, dans un contexte de développement durable. Les « feuilles de route » stratégiques, élaborées au niveau européen, national ou régional, consacrées aux potentialités énergétiques de l’hydrogène, ainsi que l’analyse des publications scientifiques ont cependant identifié le manque d'infrastructures, comme l'un des principaux obstacles au développement de l'économie « hydrogène ». Cette étude s’ins

Streszczenie:

Le problème de la métallisation de l'hydrogène, posé il y a près de 80 ans, a été désigné comme la troisième question ouverte en physique du XXIe siècle. En effet, en raison de sa légèreté et de sa réactivité, les informations expérimentales sur l'hydrogène à haute pression sont limitées et extrêmement difficiles à obtenir. Il est donc essentiel de mettre au point des méthodes précises pour guider les expériences. Dans cette thèse, nous nous concentrons sur l'étude de la structure électronique, y compris les phénomènes d'état excité, en utilisant les techniques de Monte Carlo quantique (QMC).
