Target Window Reliability
The target window design implemented and tested in experiments at ANL have performed without failure for the available beam of 6 mm FWHM on a 12 mm diameter target. However, scaling that design to a 25 mm diameter target size for a 12 mm FWHM beam has proven problematic. Combined thermal and mechanical (pressure induc…
Феноменологічне обгрунтування впливу гідратації фосфогіпсової матриці з рідкоземельним наповнювачем на її радіаційно-захисні властивості
The adequacy of the proposed phenomenological model, according to which phosphogypsum matrix hydration leads to the abnormally high in comparison with the classical Bouguer, growth-section of interaction of X-rays of radiation protection (RP) filler in the form of rare earth elements (REE). The dependence of changes i…
Injectable High Viscosity Liquid Carriers for Bone Tissue Engineering
The clinical management of critical sized defects and traumatic bone injuries continues to challenge the orthopaedic field. The gold standard of treatment uses autologous bone grafting to promote repair. While effective in many cases, donor site morbidity is a common complication. The field of bone tissue engineering…
Influence of Boronizing Treatment on Fe–Mn–Al–Si–C Steel
Abstract Austenitic Fe–Mn–Al–Si–C steel provides excellent cold formability and lower density compared to conventional stainless steels. These steels owe their corrosion and oxidation resistance to their aluminum and silicon contents, and the stability of their gamma phase is due to manganese and carbon alloying eleme…
Poröse Silica-basierte anorganisch-organische Netzwerke : Synthese, Charakterisierung und Anwendung neuer funktioneller Materialien
In dieser Dissertation konnte eine zweistufige Funktionalisierung von mesoporösen Silicamaterialien (im Besonderen SBA-15 und benzylverbrückten periodisch mesoporösen Organosilicas) mit einer photoschaltbaren Azobenzoleinheit etabliert werden. Der entscheidende Vorteil dieser zweistufigen Synthese ist die variable und…
Refractory boron compounds for high performance: Theory and experiment
We have shown that novel synthesis methods combined with careful evaluation of DFT phonon calculations provides new insight into boron compounds including a capacity to predict Tc for AlB2-type superconductors.
ANALYSIS OF WELDED POLYPROPYLENE STRUCTURES: COMBINATION OF EXPERIMENTS AND SIMULATIONS
The effect of joining by extrusion welding on the tensional stiffness and strength of a Polypropylene copolymer was analysed. Short-term and creep tests with laboratory specimens were conducted. Welded joint sub-components were simulated with the finite element method and the results were validated by experiments.

STRUCTURAL AND MECHANICAL CHARACTERIZATION OF DEFORMED POLYMER USING CONFOCAL RAMAN MICROSCOPY AND DSC
Polymers have various interesting properties, which depend largely on their inner structure. One way to influence the macroscopic behaviour is the deformation of the polymer chains, which effects the change in microstructure. For analyzing the microstructure of non-deformed and deformed polymer materials, Raman spectr…
Contrôle temporel de la cavitation ultrasonore : application à la thrombolyse ultrasonore extracorporelle
Les ultrasons focalisés permettent d’effectuer des traitements thérapeutiques ciblés dans le corps humain. Dans le domaine des applications cardiovasculaires, ils permettent de détruire des caillots sanguins susceptibles de se former dans le système vasculaire. Dans ce cas, les mécanismes de thrombolyse sont largement…
Flexible power for flexible electronics
Materials Science A challenge for flexible electronics is to couple devices with power sources that are also flexible. Ideally, they could also be processed in a way that is compatible with current microfabrication technologies. Huang et al. deposited a relatively thick layer of TiC on top of an oxide-coated Si film.…
Cover Picture: Cerium‐Complex‐Catalyzed Oxidation of Arylmethanols under Atmospheric Pressure of Dioxygen and Its Mechanism through a Side‐On μ‐Peroxo Dicerium(IV) Complex (Chem. Eur. J. 12/2016)
A cerium complex with a dianionic pentadentate ligand acted as a catalyst for aerobic oxidation of arylmethanols, in which a dinuclear cerium(IV) side-on peroxo complex was the key intermediate. The corresponding trivalent complex was able to activate dioxygen, and the oxidation proceeded catalytically under atmospher…
