The objective of the present study is to assess the influence of temperature variation on phase composition of Ca-Mg-Al hydrotalcite. The temperature variation (50-90 °C) used to Ca-Mg-Al hydrotalcite synthesis from brine water and AICl3.9H20 by a coprecipitation method. The products were characterized by X-ray diffra…
Copper phthalocyanine junctions, fabricated by magnetron sputtering and evaporating methods, show multi-polar(unipolar and bipolar) resistance switching and the memory effect. The multi-polar resistance switching has not been observed simultaneously in one organic material before. With both electrodes being cobalt, th…
Miniaturization of microarrays is one of the key challenges in the development of advanced biosensing devices. Downscaled biosensors require smaller amounts of expensive biological receptor material, such as antibodies, enzymes and cells. This lowers their costs tremendously and makes them superior to existing devices…
Under the influence of an electric field, ionic electro-active polymers generally bend or deswell, depending on the shape of the polymer matrices and its position relative to the electrodes. In this study, we investigate the bending behaviour of regenerated cellulose-based ionic electro-active composites for the fabri…
A long-term monitoring of soil physiochemical properties, plant and animal communities of the restored SENT landfill sites was conducted between 2003 and 2012. Permanent plots were monitored at (1) east boundary (DQ), (2) eastern part (EQ) and (3) south boundary (FQ); compared with a site inside SENT landfill which wa…
La mina La Isla se localiza a 2,5 Km al sur de la localidad de José de la Quintana, en el departamento Santa María de la provincia de Córdoba (Argentina). Sus coordenadas son 31º49’30.6”S y 64º24’53”O (Figura 1a). \nLa región presenta afloramientos del Complejo Metamórfico La Falda, compuesto por gneises biotíticosmus…
After more than 100 years of research, the nature of glasses (and disordered condensed matter, in general) and glass transition-related phenomena is still an open issue in condensed-matter physics [1] and the chemicophysical sciences [2]. Thin films of cry vacuum condensates of ethanol formed by condensation of the ga…
Els carburs de metalls de transició (TMC) exhibeixen propietats químiques i catalítiques similars a les dels costosos metalls nobles. La conversió d'alcohol, hidrogenació d'olefines i altres reaccions importants han demostrat l'aplicabilitat d'aquests compostos en processos industrials. També se sap que nanopartícules…
The increasing use of polymeric biomaterials in the health industries has created many new methods for the processing of polymers into lifesaving products; however, many processes often include the use of toxic organic solvents throughout the manufacturing and fabrication process. The micro-/nano-fibrillar composite (…

采用动态硫化法制备了乙烯-乙酸乙烯酯共聚物/充油丁苯橡胶热塑性硫化胶（EVA/SBRTPV）,在此基础上以聚烯烃弹性体（POE）替代部分EVA制备出低硬度TPV,并对其力学性能、Mullins效应和微现形貌进行了研究.结果表明,当EVA/SBR（质量比）为30/70时,TPV的综合性能良好;当EVA/POE/SBR（质量比）为25/5/70～20/10/70时,TPV的扯断伸长率超过1 000％,邵尔A硬度在50左右.EVA/POE/SBR TPV存在明显的Mullins效应,拉伸比一定时,最大应力和内耗随循环拉伸次数的增加而下降,瞬时残留变形则逐渐增大;拉伸比增大时,最大应力、瞬时残留变形和内耗均增加.基体中POE的存在赋予TP…

Le interazioni carboidrati–lectine giocano un ruolo fondamentale in diversi processi biologici come ad esempio nelle infiammazioni, embriogenesi, sviluppo cellulare, etc..1 Sebbene l’interazione tra lectine e carboidrati sia un’interazione debole, la possibilità di instaurare contemporaneamente interazioni multiple t…
The thermochemical behavior of two groups of ionic liquids (ILs), 1-ethyl-3-methylimidazolium [EtMeIm] and 1-butyl-3-methylimidazolium [BuMeIm] halides (Cl, Br and I) was investigated for their crystalline and liquid states in the temperature range from −100 °C to 600 °C using DSC and thermogravimetric analysis (TGA).…

There have been investigated the conductivity of a-C:H and a-C:H films, obtained by ion-plasma magnetron sputtering with different substrate temperatures. It is found that the conductivity of a-C:H films substantially dependent on deposition temperature and by changing it from 50 to 200°C conductivity reduced from abo…
This thesis covers reduction-annealing synthesis of nanostructured SiC-TiCN and SiC-TiC particulate composite powders. These were characterized by X-ray diffraction and electron microscopy. In the SiC-TiC powder it was found that TiC could be added in certain amounts by reducing controlled amounts of titanium chloride…

Many reasons make magnesium and its alloys the best potential materials for biodegradable implants: (i) magnesium is an essential element to humans and beneficial for bone strength ; (ii) magnesium degrades in physiological solutions ; and (iii) the mechanical properties of magnesium are similar to those of natural bon…
