An Edge‐on Impact (EOI) technique, developed at the Ernst‐Mach‐Institute (EMI), coupled with a Cranz‐Schardin high‐speed camera, has been successfully utilized to visualize dynamic fracture in many brittle materials. In a typical test, the projectile strikes one edge of a specimen and damage formation and fracture pro…

Chalcogenide based phase change memory (PCM) is a promising type of non-volatile memory that possibly replace the currently wide spread flash memory. Current research on PCMs targets the integration, feasibility, and reliability of such memory technology into the widely used CMOS process technology. Such studies ident…
A composite coating from Amaranthus cruentus flour and stearic acid (10 g stearic acid/100 g flour, 26 g glycerol/100 g flour and stirring speed at 12000 rpm) was applied on fresh strawberries in or- der to verify the effect on its quality. Other treat- ments were effected to comparison: PVC film, bi- layer coating of…
Solubility is a basic phenomenon underlying most industrial processes.The objective of this project is to produce a book that will bring together recent developments in solubility studies that have a bearing on industrial applications, especially the rigorous work that is underpinned by thermodynamic considerations.Th…
Organic semiconductors (polymers and small molecules) are widely used in electronic and optoelectronic technologies. Many devices are based on multilayer structures where interfaces play a central role in device performance and where inorganic semiconductor models are inadequate. Synchrotron radiation techniques such…
Potassium exchange-equilibrium parameters were outcome from quantity-intensity (Q/I) isotherms, i.e. K equilibrium activity ratio ( K O AR ), equilibrium potential buffering capacity for K ( K o PBC ), K labile (KLab), free energy of K replenishment ( K equ G ∆ − ); non-specific (Kx) and specific (∆Kequ) potassium, pr…
Through the use of bulky cyclic terminal groups, anticlinic smectic C phases have been observed in 2-methylbutyl materials based on the MHPOBC motif.
A porous nickel tubular support of diam was successfully created by heat-treating a commercial nickel tube. The resulting tube contained uniform pores, whose diameters ranged from 0.5 to , depending on treatment temperature. The porous metal tube obtained is a promising candidate for support materials for microfuel ce…
In order to study the effect of Cerium on martensitic transformation and microstructure of Ti49.3Ni50.7 alloy, a group of TiNiCe alloys with different content of Ce addition were prepared. The microstructure and the martensitic transformation behavior of TiNiCe ternary alloys were investigated by optical microscopy, s…
In this study, we attempted to deposit low dielectric constant a-SiCO:H as a copper diffusion barrier by the plasma-enhanced chemical vapor deposition method using an organosilicon precursor, bis(trimethylsilylmethane) (BTMSM, C 7 H 20 Si 2 ). The dielectric constant of the a-SiCO:H films increased from 2.54 to 3.25 a…
<b>Objective:</b> To investigate the effects of the methylene chloride:methanol (CH2Cl2:MeOH, 1:1) extract of the dried roots of <i> Mondia whitei</i> Linn and its hexane and methanol fractions on potassium chloride (KCl) and adrenaline (Adr)-induced contractions of rat vas deferens. <b> Materials and Methods:</b> Iso…
The SiO 2 -Fe 2 O 3 (F 3 O 4 ) system has been studied in air, oxygen, and an inert atmosphere. The dissociation temperatures for iron oxides, the onset and full melting temperatures for coexisting phases, and the melt demixing temperatures have been determined as a function of the oxygen partial pressure. A scenario…
We have successfully prepared an unsymmetrical analogue of a Katsuki-type salen ligand having a hydroxyalkyl group at the 6-position of just one of the binaphthyl units in the ligand, and also several Mn(III) complexes; these complexes have been attached to a polymer by an ester link and such polymer catalysts have be…
Ba 2 Zn S 3 : Pr phosphors, emitting white to green light, were synthesized by the double-crucible method. X-ray diffraction results indicate that the raw materials were completely sulfurized at 1000 ° C for 2 h . All samples doped with 0.05 – 10 mol % Pr 3 + had orthorhombic crystal structures. The emission spectra a…
The densification and electrochemical activity for oxygen reduction of the bismuth ruthenate pyrochlores, synthesized by the Pechini method, have been investigated as the interconnect and cathode materials for intermediate temperature solid oxide fuel cells (IT-SOFCs). The substitution of bismuth on the ruthenium site…
The continuous-wave/time-resolved photoluminescence (CWPL/TRPL) and capacitance–voltage (C-V) analysis of multirecipe silicon-ion-implanted are demonstrated to study the lifetime evolution of three radiative defects with luminescent peaks at 415, 455, and , which are identified as the weak oxygen bonding (O–O) defects…
Abstract Numerical simulations and experimental studies of the lasing effect in chiral liquid crystals are presented. It is shown that ring-like light emission, which is often observed experimentally, is a true lasing effect. Lasing condition and different modes in thin liquid crystal layers are discussed.
The photophysical properties of tetrakis(1,1-dimethyl-2-trimethylammonium)ethylphthalocyaninato zinc(II) tetraiodide (I) – a water-soluble cationic phthalocyanine – are presented in the presence of human serum albumin (HSA) and in micelles of sodium dodecylsulfate ( SDS ) and hexadecyltrimethylammonium chloride ( CTAC…
Lipid-packaged, mixed-valence linear platinum complexes are dispersed in chloroform, chlorocyclohexane and in methylcyclohexane. They show indigo-colors, which are identical to solid samples. These lipid-complexes display supramolecular thermochromism, resulting from heat-induced dissociation and recovery of coordinat…
