In this research we intended to obtain and characteriz composite layers by using epoxy resin (disperse phase) electrodeposited with zinc (metal matrix). The epoxy resin/Zn layers were electrodeposited at two values of current densities: 3 A/dm2 and 5 A/dm2 from a suspension of epoxy resin particles with two mean diame…

Cellulose nanofibres are found in all plants and have the potential to provide a sustainable biobased material source. These nanofibres can be used for reinforcing polymers and thus as structural m ...
Preparation and characterisation of nanoparticle-doped commingled composites for improved fire performance
KTI11 alias DPH3, kodiert für ein kleines, hoch konserviertes Zink-Finger Protein der Zn-ribbon Klasse. Kti11 interagiert mit mindestens drei verschiedenen Proteinen oder Proteinkomplexen: dem Dph-Komplex, der für die Diphthamid Biosynthese am eukaryotischen Translationsfaktor 2 (eEF2) notwendig ist, dem Elongator-Kom…
Background. \nPeriodontal disease happens approximately at 10% of adult populations, characterized by loss of attachment beetwen tooth and bone, resulting in bone resorbtion and eventually bone loss. In the wound healing process to repair bone tissue, macrophage have an important role. To facilitate \nthe healing proc…
采用浮区法生长了质量较好的Si:beta-Ga_2O_3单晶,直径约为8 mm,长度约为2 cm。进行了X射线粉末衍射和X射线荧光分析,结果表明所得Si:beta-Ga_2O_3单晶属于单斜晶系,而且Si确实进入了beta-Ga_2O_3格位中;在室温下测试了Si:beta-Ga_2O_3吸收光谱,吸收截止边约为255 nm,并分析了退火对吸收截止边的影响;测试了荧光发射谱,研究了不同激发波长对其紫外及紫色波段发光的影响。

Mesoporous VOx@carbon composites were synthesized via ultrasound-assistant impregnation method with mesoporous carbon C-FDU15 as the host. The composites with 32.26 wt% V2O5 loading yield the best capacitance (128 F/g) in 1 mol/L KNO3 electrolyte.
The paper deals with numerically investigating the processes of elasto-viscoplastic deformation of cap-shaped specimens loaded in tension in the strain-rate range of 102 s-1 to evaluate strain rates and values implemented in the experiments on dynamic failure of structural materials on a vertical gas-gun stand. Keywor…
Se desarrollo una matriz semirrigida biodegradable a partir de harina nativa de yuca MBRA383 pregelatinizada y fibra de fique por la tecnica de moldeo por compresion. En donde se propuso realizar mejoras dentro del proceso de obtencion del empaque biodegradable, principalmente enfocadas a encontrar las variables optim…
This review focuses on: (a) describing the physicoelectrochemical transport phenomena in alkaline Anion Exchange Membrane Fuel Cells (AEMFCs) and acidic Proton Exchange Membrane Fuel Cells (PEMFCs) fed with hydrogen or hydrogen-rich alcohols, such as e.g. ethanol, methanol, and (b) reporting alkaline AEMFC vs. acidic…
The present work presents a report on an experimental investigation on commercial pellet stoves aimed to fully understand which parameters influence CO and NO emissions (NO2 is present in negligible quantities): tests are performed on different type of pellet stoves varying nominal power, combustion chamber size and c…
Al-Si based alloys are of great importance to the automotive, aerospace and engineering industries. Owning to the high fluidity imparted by the presence of relat-ively large volumes of the Al-Si eutetic, it is possible to cast complex shapes with high dimensional precision. The eutectic composed of Al cells in which S…

Although it is well known to employ compatibilizer to assist clay dispersion in thermoplastic/clay systems, the properties of compatibilizers have often been neglected. Metallocene polyethylene (mPE)/clay nanocomposites were prepared via a melt-blending approach to further investigate this compatibilization effect. Ma…
