MnCo2O4/Au was investigated as an electrocatalyst for the oxygen reduction and evolution in alkaline media. Polarization curves showed an unprecedented activity for the oxygen reduction due to a synergistic effect between MnCo2O4 and Au, involving CoII/CoIII-MnIII/MnIV, as revealed by in situ X-ray absorption near edg…
Fibre supercapacitors were designed and manufactured using a dip-coating method. Their electrochemical properties were characterized using a VersaSTAT 3 workstation. Chinese ink with a fine dispersion of carbon and binder was coated as the electrode material. The specific capacitance per unit length of a copper fibre…
This paper analyzes theoretically and numerically the refraction phenomenon of detonation wave at the explosive-metal interface, motivated by the problem that there exist large discrepancies between the experimental results and the classical shock polar theory. After pointing out the major defects of the classical sho…
Recent theories have revealed topological differences between one-dimensional (1D) Heisenberg antiferromagnets (HAFs) with odd and even integer spins (S). With this renewed interest, we have investigated the low-field magnetic susceptibility, specific heat, and high-field magnetization of single-crystal samples of MnC…
With the emergence of smart textiles, the research into textile-based sensors has increased as well. These sensors have the advantage of being flexible, and compatible with clothing thus more unobtrusively integratable and more comfortable to wear. On the other hand, one of the purposes of clothing is to enhance the t…
Wzrost zainteresowania wykorzystaniem roznorodnych nanomaterialow w technologii, przemyśle, medycynie i zyciu codziennym skutkuje zwiekszeniem ich produkcji, a w konsekwencji emisji do środowiska naturalnego. Ze wzgledu na liczne doniesienia o negatywnym wplywie nanocząstek na komorki drobnoustrojow, roślin i zwierząt…
Fe 2 SiO 4 @C nanocomposites are prepared via a solid state reaction by controlling different calcinating temperature (600 C 700 C and 800 C) under the flow of nitrogen gas. XRD analysis indicates that a typical -Fe 2 SiO 4 phase is detected in the Fe 2 SiO 4 @C nonocomposites calcinated at 700 C and 800 C. SEM result…
Starch is one of the most abundant polysaccharides found in nature and is widely utilized in various fields of industry. Due to the complex structure of native starch it is insoluble in most organic solvents and needs modification prior utilization. In this study, ionic liquids (ILs), modern green chemistry alternativ…
The presence of hydrogen in iron alloys leads to an impairment of mechanical properties. This can be related to the production routes and material processing. Microsegregations, grain size and surface finishing play a very important role on the ductility response in hydrogen. Particularly, a more homogeneous distribut…
Nowadays, heavy duty diesel engines are usually equipped with urea selective catalytic reduction (SCR) systems to remove the NOx emissions. To design a high performance urea dosage controller for the SCR systems, a control-oriented SCR model is essential. In the last decade, a few control-oriented SCR models have been…
The aim of this research was to study the effects of the coupling agents, FusabondTM E-528 (polyethylene-grafted maleic anhydride; PE-g-MA, MA) and Amino Silane (Si), on the thermal properties, and mechanical properties of Eucalyptus flour-HDPE composite. Variation of the Eucalyptus flour contents in the HDPE resulted…
Aim: The purpose of this study was to find any difference in general physical fitness between tobacco and nontobacco chewers. Materials and Methods: A total of 50 subjects were participated in this study in which 25 subjects with mean age 20.30 (±2.11) were nontobacco chewers and placed in Group A, whereas, other 25 s…
Недеформированные рудоносные интрузивы Норильского рудного поля (НРП) пересекли смятые в брахисинклинали вулканиты трапповой формации Р2 Т1. Из-за неравномерной нагрузки на кровлю интрузивов большая часть сульфидных расплавов оказалась выжата в головную часть рудоносных интрузивов, причем более легкоплавкие NiFeCu-с…
Ligand-protected gold nanoparticles show interesting and promising properties for various applications such diverse as biomedicine, catalysis, photonics or nanoelectronics. The understanding of the interaction at the interface is essential to optimize and control properties. In order to understand the binding nature o…

Binderless compressed veneer panels from oil palm trunk consisted of 5 layers of oil palm trunk veneers were made with 3 different thickness, 7 mm, 10 mm and 15 mm. The panels were pressed at temperature of 180 °C with pressure 5 MPa at duration time of 20 minutes. The veneers were pressed without using any synthetic…
Has made the manufacture of natural zeolite from the Sarulla, District Pahae, North Tapanuli North Sumatra Province in the form of chunks with the process of grinding to a size 200mesh (74µm).The natural zeolite refining and calcination process is carried out at a temperature of 600°C for 1 hour and without the proces…
Block copolymer-based magnetic nanoassembled structures with acidic cores exhibiting enhanced loading level of superparamagnetic iron oxide nanoparticles, thus having great potential for theranostics based on MRI.
Polyaniline (PANI) nanofibers were prepared in dilute polymerization system in the presence of organic solvents including acetone and ethanol. The as-prepared PANI nanofibers were characterized by field emission scanning electron microscopy, ultraviolet-visible absorption spectroscopy, Fourier transform infrared and R…
