Objective Hedyotis corymbosa (Shui Xian Cao, 水线草, HC) is the main antitumor medicine in China and other southeast Asian countries. A comprehensive quality control system of HC was established in this study, as the current system was ineffective. Methods Microscopy was used to observe the characteristics of the powder…
Transformer is an important component in power system. Lightning impulse will cause an overvoltage that will damage the transformer. Hence, transformer need an insulation that can protect it and withstand lightning impulse. Mineral oil (MO) was the most commonly used oil as liquid insulation. Although MO provide an ex…
Las perovskitas hibridas han tenido un impacto positivo en el campo de la energia renovable, ya que son consideradas como un material prometedor en celdas solares debido a su bajo costo y alta eficiencia. En este caso las celdas solares de pelicula delgada permiten alcanzar eficiencias significativas (21%) en relacion…
Selulit adalah suatu kelainan kulit kompleks yang terlokalisir akibat adanya herniasi lemak subkutan ke lapisan dermis yang mengakibatkan kerusakan jaringan ikat di bawah kulit sehingga tampak sepeti kulit jeruk (orange peel). Selulit dijumpai sekitar 80-90% pada wanita paska pubertas. Hal ini terkait peranan hormon e…
Automobile body always bumps, resulting in a large number of pit package damage to happen, which caused adverse impacts on production. The sheet metal repairing technology were used in automobile maintenance. The theoretical basis, common methods and tools for repairing were described at first. Then procedures and sta…
Hypothesis: Nowadays, the use of scaffolds in tissue engineering to repair and regenerate human lesions, including nervous injuries has been widely considered. Also, nanofibrous scaffolds due to their structural similarity with the extracellular matrix (ECM) in the body are found to be suitable substrates for cell gro…
Polymer nanocomposites has a huge potential to serve as dielectric materials. These materials were found to have a great capability in withstanding high voltage levels. In nanocomposites development, the breakdown strength of the materials was often reported to be higher, lower or similar, in comparison with the unfil…

In this dissertation, density functional theory calculations are performed to calculate the thermodynamic and electrochemical properties of metal coordinated frameworks for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Gibb's free energy, overpotential, charge transfer and ligands effect are eva…
Photons absorption into nanoparticles dimensions leads to a large increase in its electromagnetic intensity and the nanoparticle's radiated properties. The strongly absorbed light by the nanoparticles is followed by converted efficiently into thermal energy to kill harmed cells without affecting the surrounding health…
Zinc metalloproteins are heavily involved in a wide variety of human diseases,¹ such as rheumatoid arthritis, periodontitis, and cancer. Matrix metalloproteinase (MMP) and carbonic anhydrase (CA) are two zinc containing enzymes that are seen as attractive biomarkers for a multitude of pathological conditions, due to t…
This paper presents a detailed review on the shaped charge technology. The concept of shaped charge is explained by elaborating the Munroe effect and liner collapse phenomena. The military as well as civil applications of this technique is highlighted. The development of shaped charge technology is reviewed from histo…
This paper introduces a design of compact size perforated reflectarray/transmitarray based on the substrate integrated waveguide technology (SIW) for 5G communications at 28 GHz. The proposed SIW reflectarray antenna has advantages in compact size, easy fabrication and high gain and reduces the size of the antenna. Th…
The occurrence, special aspects of structural determination, biological activities, and potential taxonomic application of eremophilane-type glycosides, a rare group of metabolites from higher plants, are reviewed. This mini review covers the literature published for period 2006 to 2018.
The results of research on the aging of glass-filled polycaproamide materials are reviewed. The data on the influence of the type and concentration of glass fillers, stabilizers, and modifiers of different chemical structures, used in the manufacture of glass-filled polyamides, on the formation of the supramolecular s…
Research on the implementation of inductive proximity sensors in active magnetic bearings is performed in this paper. LDC1000 digital sensors manufactured by Texas Instruments are used since they claim to provide precision measured in microns and simple acquisition of the output data. The Sensor chip is connected with…
Abstract This publication presented the main issues related to fatigue of polymer composite materials. It was featured a fatigue stress test based on composite sample, made of carbon fiber-reinforced polymer, using the four-point bending method. The test was carried out with the initial load and using positive load cy…
In this study, the thermal stress of a 3-D planar solid oxide fuel cell, simulated within COMSOL Multiphysics, is investigated when the inlet boundary conditions of velocity and temperature for the fuel and oxidant are varied. Prior to the 3-D simulation, a 2-D flow study was conducted to investigate the effect the pe…
Tiny nanostructured high-energy power sources based on the direct conversion of nuclear energy to electricity are developed for power supply of microelectronic and micromechanical devices, as well as remote objects. The role of energy converters in such power sources is played by metal–insulator–metal (MIM) structures…
The Phase Change Material (PCM) is explored as potential passive thermal solution in package thermal design due to the burst power requirements in the mobile applications.
