Published: August 2019

Abstract
Immense progress is required in the field of energy conversion and storage to achieve cost-effective high-performance batteries which could meet future energy demands. It also becomes mandatory to utilize the abundant materials from the earth’s crust, along with safe conversion and storage of electrochemical reactions. In this perspective, aluminium ion batteries (AIBs) could be a viable alternative for the conventional lithium-ion batteries (LIBs). In this mini-review, we focus on the challenges and the latest growth related to the cathode active materials (metal oxides, metal sulfides and other hybrid systems) in AIBs. The development of highly efficient, low cost and safe energy storage systems based on aluminium ion batteries is much explored. Still, commercialization remains a theoretical one, hence this review highlights the significance of the developed materials and their shortcomings that need to be addressed for the commercialization of aluminium ion batteries in the future.

Abstract
The nuclear power station severe accident in Fukushima Daiichi became an important lesson learn to involve the passive cooling system in order to enhance the safety in a nuclear power station when prolonged station blackout occur. A U-shaped heat pipe is proposed as one of alternative passive cooling technology to absorb the decay heat generation in the cooling tank that connected to the reactor cavity cooling system. This research objective is to know the effective thermal conductivity of the U-shaped heat pipe. The effective thermal conductivity is an important factor to know the effect of the U-shaped heat pipe to remove the decay heat generation to the heat sink. An experiment was conducted to know the effective thermal conductivity of U-shaped heat pipe. The air cooling velocities on a bonded-fin heat sink in the condenser section were used as a parameter to obtain the effective thermal conductivity of U-shaped heat pipe. The air cooling velocities were varied at 0.65, 0.74, 1.02, and 1.21 m/s. The experiment results showed that the effective thermal conductivity of 35.37 was obtained at the highest variation of air cooling velocity on a bonded-fin heat sink in the condenser section. The result obtained shows that U-shaped heat pipe as a heat transfer device has thermal conductivity 35.37 times greater than the solid U-shaped Copper with the same geometry and dimension. This investigation results can be used to justify the use of heat pipes as a good passive cooling system in cooling tanks connected to Reaktor Daya Eksperimen reactor cavity cooling system.

Authors: Yayienda N F , Azzumar M , Faisal A 
Published: August 2019

Abstract
Monitoring of the dc resistance value of a multiproduct calibrator had been implemented. This multiproduct calibrator is commonly used as a reference standard to calibrate electrical measurement testers such as insulation tester, earth tester, continuity tester, ground bond resistance tester and many other resistance meters. The monitored value of the multiproduct calibrator can be used to support measurement traceability needs for those electrical measurement testers and meters in a power distribution utility. The monitoring was done by measuring nine data of resistance value within nine respective days to constructa preliminary statistical control limits. The measurement was continued monthly to monitor the dc resistance value that was intended to test the control limits. The monitoring is performed by doing F-test and T-test on the recent measurement data over the all previous measurement data. If a measurement data is found to be outside the control limits, an action should be done to accommodate the information and renew the statistical control limits. The renewal action for the dc resistance value of the observed multiproduct calibrator was performed for several times within a year. It is reported based on the method implementation acquired within a year, that the upper control limit (UCL) and the lower control limit (LCL) for the dc resistance value of 19 kΩ is 18.99964 kΩ and 18.99912 kΩ. Moreover, to verify the performance of the final statistical control limits, the additional measurement is taken and the result lies between the UCL and LCL

Abstract
One of the most important concepts of the internet of things is related to software services, where the system must be able to provide real-time data collected from various environments. So that software services represent a variety of physical and virtual real-world objects that can grow very fast. This condition is related to the ability of self-adaptation software services. However, the existing model of self-adaptation is generally not paying attention to the requirements for service evolution. The objective of this paper is to introduce self-adaptation modeling techniques which consist of, first, domain modeling of the internet of things to represent real-world context; second, developing an inference engine for context inference. As a form of evaluation, this model is applied to the patient monitoring system that will relate to the concept of self-adaptation of various systems, devices, actors, and environment. The case study results show the system’s ability to anticipate changes in context and growth needs.

Abstract
The aim of this study is to investigate and analyze the NdFeB N52 type magnetic field distribution on a Trapezoidal type coil in an axial type generator. The main problems addressed by this study are how the distribution of magnetic field type NdFeB N52 to the trapezoidal type coil and how the influence of air gap between NdFeB N52 magnets and the coil to the output electric voltage generated from the coil at the speed of rotation. In order to answer the problems, we moved a rectangular type magnet axially towards the trapezoidal type coil with a specified distance, so that we could identify the change of the output voltage. The description of the magnetic field distribution in the stator was simulated by using the Maxwell 3D Design application ran in ANSYS software 16.0. The result of this study shows that the magnet was distributed evenly on the coil. It is also known that based on experiments with 2mm to 6mm of magnet to coils of gaps, the highest output voltage is at 2mm gaps at 750rpm.

Published: August 2019

Abstract
Chitosan:SiO2 nanocomposite (Cs:SiO2 NCs) is synthesized via aerosol processing. Ultrasonic spray drying apparatus was used to produce smaller sized composite particles with spherical morphology. Composite from shrimp shell and water glass (Na2SiO3) as silica precursor were used for the preparation. Cs:SiO2 NCs were characterized by Fourier Transform Infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) to know about the chemical bonding and morphology of the particles, respectively. Based on the FTIR investigation the absorption peak at 1090 cm−1 represents the reaction of silanol groups of silica with carbonyl groups of polymers leading to the formation of Si-O-C bonds. The morphology of Cs:SiO2 NCs was more spherical than chitosan particles with relatively narrow size distribution. The smaller particle size of Cs:SiO2 NCs is potentially applied to engineer the material for drug delivery system.

Abstract
In this paper we synthesized high entropy oxide system (Sc0.2Ce0.2Pr0.2Gd0.2Ho0.2)2O3±δ by precipitation of hydroxides from REE nitrates aqueous solutions and annealing the mixture at 800 °C. It is possible to obtain the various forms of simple and complex composition based on the rare earth oxides, including oxides in the form of nanosized powders. The main idea of obtaining HEOS comes from the field of high-entropy alloys. The interconnection between configurational entropy and mixing enthalpy is a key factor for determining phase transformations. The phase composition, structure, and surface morphology of the obtained powders were investigated by scanning electron microscopy and X-ray phase analysis methods.

Authors: Lytkina D , Gutsalova A , Pozdniakov M , Heinrich L , Kozik V 
Published: August 2019

Abstract
Composites based on a porous hydroxyapatite carcass with a coating of PLGA were obtained. According to the SEM images, it was found that, the composites had a different coating character depending on the porosity of the HA framework. After 1 week, the dissolution rate of composites increases relative to pure PLGA, and the growth is proportional to the increasing of the amount of pore-forming agent in the material by 20-50%. The dissolution rate of HA in the composition of materials also increases since the second week, because the diffusion of the solvent in the HA increases as the result of PLGA hydrolysis.

Abstract
Nowadays air and water pollutions are becoming a serious problem for urban environment. One of the efficient methods of purifying water and air is photocatalysis on TiO2 films. In this work, we obtained composite materials based on TiO2 and modified by Ag and SiO2 on the surface of the fiberglass material (Ag/SiO2/TiO2/FGM) by a sol-gel method. Complex studies were carried out to identify the phase compositions, morphology and textural characteristics of obtained samples by X-ray diffractometey, scanning electron microscopy, micro-X-ray spectral analyses and analysis of N2 adsorption-desorption isoterms. Surface area and average pore size of this sample is 8.2 m2/g and 11.4 nm respectively. Prepared composite Ag(0.5%)/SiO2(3%)/TiO2/FGM material revealed photocatalytic activity in model reaction of methyl orange azo dye photodegradation under UV-irradiation.
