(Elsevier, 2017-01)The use of titanium aluminides as high temperature materials in the aerospace and automobile industries is becoming a reality since their early research and development in 1955. Their mechanical properties at elevated ...
-
(IWBLCM, 2015-06)The biorefinery concept prescribes that the biomass should be utilized in its entirety to produce high value chemicals and materials, as well as energy. Lignin is the second most abundant biopolymer and a by-product of ...
-
(2010-01)The authors examine the question of stability of breakwater structures using the simulation software PhysX. This “physics engine” can be used to construct various packings of breakwater elements, each of which can be used ...
-
(2010-11)In the use of unsaturated zone methods to estimate recharge, the basic assumption is made that recharge occurs by means of diffusive processes (i.e. piston flow occurs). In fractured environments the reliability of recharge ...
-
(Elsevier, 2010-06)Ammonium quaternized polymers such as poly (arylene ether sulfones) are being developed and studied as candidates of ionomeric materials for application in alkaline fuel cells, due to their low cost and promising electrochemical ...
-
(2009-06)Recently, alkaline direct alcohol fuel cells have received increased attention for the following reasons: anion charge carrier (OH) movement from cathode to anode, opposite to the movement of protons in proton exchange ...
-
(American Physical Society, 2013-04)Mutually unbiased bases (MUBs) play a key role in many protocols in quantum science, such as quantum key distribution. However, defining MUBs for arbitrary high-dimensional systems is theoretically difficult, and measurements ...
-
(Old City Publishing, 2014)This paper reports the material characterization of Ti6Al4V/TiC composite produced by laser metal deposition. The Ti6Al4V/TiC composites were deposited with a composition ratio of 50 wt.% Ti64l4V and 50 wt.% TiC. The ...
-
(2016-06)Laser metal deposition (LMD) is an innovative manufacturing technique that uses laser to melt powders to fabricate fully dense components layer by layer. It is capable of processing different metallic powders and can also ...
-
(Electrochemical Society Inc, 1993-12)LT-LiC0.9Ni0.1O2 prepared at 400 degrees C with a structure that is intermediate between an ideal lithiated spinel and a layered structure has been investigated as an electrode in rechargeable Lithium cells; it delivers a ...
-
(Springer verlag, 1999-11)Sub microscopic opaque particles from highly shocked granite-gneisses close to the core of the Vredefort impact structure have been investigated by means of micro-analytical techniques with high spatial resolution such as ...
-
(Elsevier, 2010-05)Face centred cubic Ti – 10 and 20 Mg and Ti-6Al-4Mg (wt. %) alloy powders have been produced by high energy ball milling, under argon, of elemental powder mixtures containing a process control agent (PCA). Milling leads ...
-
(RAPDASA 2009, 2009-11)This paper is based on tests performed on die component specimens grown on an EOS RP technology platform, as well as manufactured specimens machined out of preferred standard hot work steel DIN 1.2344. These specimens ...
-
(2013-10)This paper presents the characterization of microfluidic components for the realization of low-cost point-of-care diagnostic devices, with focus on full blood count applications. Increasing emphasis is being placed on ...
-
(2009-08)The characteristics of the roadbed material are critical to the overall performance of the pavement. The paper presents examples with discussion of the form of distress experienced within the pavement layers, based on ...
-
(2015-11)This paper presents the preliminary outcomes to develop and optimize methods to characterize DPM and respirable dust samples for the following: Crystalline compounds Common mineral analyses Particle size distribution ...
-
(Editorial office of Transactions of Nonferrous Metals Society of China, 2010-09)Semi-solid metal (SSM) processing is a unique manufacturing method to produce near-net shape products for various industrial applications. The nature of the SSM slurry (with solid spherical grains suspended in a liquid), ...
-
(2013-09)Tensile properties and hardness of the as received and heat treated samples were evaluated. Optical and scanning electron microscopy were used to investigate the microstructure of the as received and heat treated Ti6Al4V ...
-
(Elsevier, 2015-03)Titanium-manganese oxide composites as suitable material for electrode in electrochemical capacitors application was synthesized using spark plasma sintering technique. The feedstock powders were blended at varied compositions ...
-
(Springer Verlag, 1993-01)A Bacillus brevis gene coding for an endo-(1, 3-1, 4)-beta-glucanase was cloned in Escherichia coli and sequenced. The open reading frame contains a sequence of 759 nucleotides encoding a polypeptide of 252 amino acid ...
