α-Al 2 O 3 :C is a highly sensitive material for thermoluminescence dosimetry (TLD), but exhibits strong light-induced fading. This light sensitivity can be exploited, however, in optically stimulated luminescence dosimetry (OSLD) when the detector is stimulated with light after exposure to radiation and luminescence…
The crystal structure of the lightly doped insulating system ${\mathrm{La}}_{1\ensuremath{-}x}{\mathrm{Sr}}_{x}\mathrm{Mn}{\mathrm{O}}_{3}$ with $x<~0.17$ has been studied in detail using neutron diffraction. It has been established that this system has two orthorhombic phases. One is the ${O}^{\ensuremath{'}}$ pha…
Barium strontium titanate, (Ba x ,Sr 1‐x TiO 3 , thin films of various compositions were prepared by a sol‐gel method. Solutions consisting of acetate powders and titanium IV isopropoxide in a mixture of acetic acid and ethylene glycol were spin‐coated onto silicon and platinum‐coated silicon substrates. Processing pa…
Sugar kinases, stress-70 proteins, and actin belong to a superfamily defined by a fold consisting of two domains with the topology beta beta beta alpha beta alpha beta alpha. These enzymes catalyze ATP phosphoryl transfer or hydrolysis coupled to a large conformational change in which the two domains close around the…
UNLABELLED: The receptor-mediated endocytosis uptake pathway for the vitamin folate was investigated as a target for tumor-selective radiopharmaceutical delivery. The molecular target for this delivery mechanism is a membrane-associated folate binding protein (FBP) that is overexpressed by a variety of malignant cell…
Crystallization processes were studied for germanium–antimony–tellurium (Ge–Sb–Te) ternary amorphous thin film as a single layer or sandwiched between various dielectric films, such as silicon dioxide (SiO2), siricon nitride (Si3N4), tantalum oxide (Ta2O5), zinc sulfide (ZnS), and ZnS–20 mol % SiO2. The processes were…
Carbon is an extraordinary element, considering the diversity of materials it forms. Ranging from sparkling gems to sooty filth, these materials have been studied and used for centuries, and carbon science was long thought to be a mature field. So when a whole new class of carbon materials—the fullerenes, such as C60—…
A model for the design of glass plates to failure is presented, which, based on the theory of plates with gross deformations for the calculation of the stress state as well as on the empirical flaws statistical distribution in the glass surface, applies fracture Mechanics criteria to establish a probabilistic predicti…
The anxiety caused by the fast growing decay of historical stained glass windows as a consequence of increasing environmental pollution, encouraged institutions of several countries to sponsor a series of scientific works aimed both to slow down this fast forwarding deterioration and to develop repair and preservation…
In the thermal exchanges between buildings and environment, glazing is an element of major importance, for it largely influences the so-called Solar Heat Gain and Thermal Losses. These parameters can be modified by applying different type of coatings onto glass surface or by adding colorant compounds during glass melt…
Stained glass windows belong to the most important cultural heritage of Europe. Within the last decades a disastrous deterioration took place. The wonderful stained glass windows and their glass paintings as pieces of art are acutely menaced by environmental corrosive influences. This corrosion process is a very compl…
