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…

The energy and geometric characteristics of graphene, when it interacts with the atoms of transition, noble and elementary metals, were calculated by the Van-der-Waals DF method. Study on the reaction of graphene sheet on contact with various molecular structures was also performed.
Decorative concrete floor coatings Prescott. Epoxy and Polyaspartic coatings for garage floors and concrete commercial properties.
The problem of the reliability and safe fatigue life of a lateral frame of a freight car is analyzed at the stage of formation of a multi-cycle fatigue crack in stress concentration zones, taking into account the stochastic nature of loading, the fatigue strength of the material and the stress concentration coefficien…
Outotec is a global leader in minerals and metals processing technology, and has over the years developed several groundbreaking technologies for this. Besides technologies in mineral and metal processes, Outotec are also developing innovative solutions for industrial water treatment, use of alternative energy sources…
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…

Die ursächliche Behandlung genetischer Erkrankungen, viraler Infektionen und Tumorleiden gelingt durch den effizienten Gentransfer bei minimaler Toxizität. Die effizienten viralen Genfähren sind jedoch stark immunogen, verfügen nur über eine geringe DNA-Beladungskapazität und die Herstellung ist kompliziert. Nicht-vir…
To achieve better biocompatibility with living tissues metal implants made of Ti-6Al-4V are often coated by calcium hydroxyapatite. Deposition techniques of calcium hydroxyapatite coatings using dipping method on metal implants almost not used. This paper presents new dipping-solution compounds used for deposition of…
Cellulose is a renewable carbon resource as well as an alternative material to replace petroleum- based plastics. Cellulose acetate butyrate (CAB), one of cellulose esters, is resistant to ultraviolet rays, has a lower moisture absorption than cellulose acetate and has an extremely high impact strength. However, it is…
The full potentialLinearized augmented planewave (FLAPW)method is employed to study the ground state and crystal properties of In2MgTiO6. The electronic-energy band structure, site and angular- momentum decomposed density of states and charge-density contours of double perovskite In2MgTiO6 are calculated by the FLAPWm…
Copper plating was performed on nickel substrate by means of the potentiostatic electrodeposition method from a sulphate electrolyte solution. The copper coatings morphology was studied by means of the optical and electronic scanning microscopy techniques. The uniform electrodeposited films have a thickness of about 1…
This paper presents three types of radial forging machines to produce the axle type pieces. The new types of radial forging machines are presented cinematically. The movement of the deformation tools at these types of machines is compared with the motion at the existing machines.

Land management agencies face uncertain tradeoffs regarding investments in preparedness and fuels management versus future suppression costs and impacts to valued resources and assets. Prospective evaluation of fuel treatments allows for comparison of alternative treatment strategies in terms of socioeconomic and ecol…
An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space grou…
A methodology of numerically analyzing the effect of the reinforcement pattern on the nature of dynamic behavior and strength of layered fiberglass cylindrical shells loaded by a single internal pressure pulse is considered. Keywords: composite materials, shells, reinforcement pattern, pulsed loading, numerical method…
