Biomaterials like calcium phosphates are used as bioactive coatings because they increase the osteointegration of the prosthesis surfaces. Micro-arc oxidation (MAO) generates TiO2 and amorphous and crystalline calcium phosphates coatings.... more
The effect of hot water dips (53 °C, 2–3 min) on chilling injury (CI) and decay of various citrus fruits was compared with the effect of curing (36 °C, 72 h). Experiments were conducted with grapefruit (Citrus paradisi Macf., cv. Marsh),... more
Titanium-zirconium based alloys containing a small amount of niobium were investigated in order to evaluate their possible use as biomedical materials. Zirconium, which belongs to the IVa group, is known to have good corrosion resistance... more
The exoskeleton of the lobster Homarus americanus is a multiphase biological composite material which consists of an organic matrix (crystalline α-chitin fibers and various types of non-crystalline proteins) and minerals (mainly calcite).... more
Titanium dioxide (TiO2) is widely used in optical coating technology because of its stability and high index of refraction. The homogeneity of the chemical composition (stoichiometry) of the optical thin films plays an important role in... more
This paper presents the effect of intercritical heat treatment (IHT) on the mechanical properties of AISI 3115 alloy steel. The steel was intercritically heat-treated at a temperature range of 730-830°C followed by water quenching. The... more
Thin films of CdS, deposited by chemical bath deposition (CBD) onto films of fluorine-doped tin oxide/glass (glass/FTO) substrates were prepared and investigated for photoelectrochemical conversion (PEC) of light into electricity. Knowing... more
The accurate description of the relaxation phenomenon near the glass transition temperature allows a better interpretation of differential scanning calorimetry (DSC) curves, since it can be separated from other thermal effects such as... more
The analysis of the mineralogical composition of most rock wastes shows the presence of a high percentage of minerals with SiO2 and Al2O3, which could be used as raw materials for ceramic products. The main objective of this work is to... more
The prothoracicotropic hormone (PTTH) of Drosophila melanogaster is a modulator of ecdysteroid (molting hormone) synthesis and was isolated and characterized from extracts of whole larvae (approximately 4 x 10(5) larvae). The purification... more

The characteristics of resistive switching of TiN/HfO2/Ti/HfO2/Pt/Ti stacks on SiO2/Si substrates were investigated and compared to TiN/HfO2/Pt/Ti stacks in order to study Ti interlayer effects on resistive switching. The Ti interlayers... more
