Effect of SiO2 Substrates Condition as Aluminum Nitride Growing Media
Today's semiconductor technology continues to develop, both in terms of material discovery, manufacturing technique, as well as implementation reduntdant. One of one use consistent terms semiconductor materials that attracts attention is AIN. Several methods have been conducted to grow AIN, one of them is using the re…
Thermoelectric Generator Powered by Focus Sunlight Reflection
The objective of this research is to convert heat from the sunlight to electricity by using thermoelectric generator (TEG). Electrical power is produced by temperature difference between the hot and cool junctions at the thermoelectric generator. The proposed system consists of magnifying glass and is equipped with th…
Flow Simulation Analisys of Modified Lower Hose Radiator
The cooling system on the engine having a function to prevent excess heat, but also has a negative impact on the ability of the engine to produce fuel power. One way to utilize heat energy of cooling water on internal combustion engine is using a thermoelectric generator (TEG). The TEG is placed between the upper hose…
Design and Geometrical Analysis on Steel Welded Frame of Mini CNC Milling Machine
Centre of vocational development Politeknik Manufaktur Astra has the objective to contribute to vocational high school (SMK) quality improvement. The target is on CNC machining competency. The CNC milling machine was taken as a development project since most of SMK need it but did not have it. As a machine, it should…
Design Modification and Supporting Device Development in Rapid Prototyping Machine
Rapid prototyping machine with FDM (Fused Deposition Modelling) is a machine used to create a prototype by inserting thermoplastic material into the extruder until the phase changes from solid to semisolid and the prototype becomes fully 3D. This research was carried out to replace and to modify damaged support device…
Evaluation of polyoxymethylene dimethyl ether synthesis based on dual fluidized bed steam gasification
Derzeit wird ein Großteil der verwendeten Biotreibstoffe aus Anbauflächen gewonnen, die im Wettbewerb mit der Nahrungsmittelproduktion stehen. Durch die neue europäische erneuerbare Energie Richtlinie soll sich das nun ändern, denn in Zukunft sollen sogenannte fortschrittliche Biotreibstoffe den Hauptbestandteil an re…

ALTERNATE METHOD FOR DETERMINING A TSPI SOLUTION BASED ON TM SIGNAL STRENGTH
The continual advances in military system technologies compel the Test & Evaluation community to constantly mature and adapt test methodologies and instrumentation capabilities. The need for alternate approaches aimed at collecting in-flight missile Time Space Position Information (TSPI) that compliment on-system high…
Extraction and characterization of microfibrillated and nanofibrillated cellulose from office paper waste = Pengekstrakan dan pencirian mikrofibril dan nanofibril selulosa daripada sisa kertas pejabat
The tremendous increase in papermaking and cellulose production, both of which are sourced from wood pulp, has resulted in the severe exploitation of trees, thereby leading to environmental problems, including deforestation. Besides, the reduction of paper usage is not on the horizon. Thus, when it comes to the enviro…
Thermodynamics and phase transitions in model polymer blends and thin films
This study is concerned with the phase behaviour of partially miscible highly interacting poly mer blends and thin films. In this context, ’highly interacting’ refers to a steep slope of ther modynamic interaction with inverse temperature, such that a small temperature variation in duces a substantial change in thermod…
Graphene inspired sensing devices
Graphene’s exciting characteristics such as high mechanical strength, tuneable electrical prop- erties, high thermal conductivity, elasticity, large surface-to-volume ratio, make it unique and attractive for a plethora of applications including gas and liquid sensing. Adsorption, the phys- ical bonding of molecules on…
Análise magnética e mecânica em transformadores sob correntes de energização e energização solidária
O transformador de potencia e um dos equipamentos mais importantes no sistema eletrico de potencia, permitindo a viabilidade da conexao dos centros geradores aos centros consumidores, mesmo estando a longas distâncias. O seu funcionamento de forma confiavel e continuo e de fundamental importância para a manutencao do…
A Future Concept in Material Science
We present a future concept in material science, which we believe will lead to solve many problems researchers have experienced in the past. Our new method is a step forward to conceptualizing key experiments in material science and will provide researchers among the world an important tool towards realizing their goa…
Surface Modification of Chitosan Films/Meshes for Biomaterial Applications
Biyomalzemelerin yüzeylerinin değiştirilmesi, biyolojik ortam ile ilk teması malzeme yüzeyinin yapması nedeniyle büyük ilgi görmektedir. Bu tez, yoğun ve asimetrik kitosan filmlerin kimyasal, yüzey ıslanabilirliği, protein adsorpsiyonu ve biyolojik olarak parçalanabilirlik özellikleri üzerindeki yüzey modifikasyon etk…
Partitioning of Inert Colloids Particles in Phase-Separated Polymer Solutions and their interfacial behaviour on phase boundaries
Phase separation commonly occurs in solutions containing two different incompatible polymers due to insufficient interdroplet repulsion forces and thus their coalescence. Segregative phase separation is the main type in this study, depending on the concentration when there’s no specific interaction between components…
Strength and Fracture Behaviour of Dual Phase Steel Dp450 in Static and Dynamic Conditions
In this work, strength and plastic deformation effect of the dual phase steel are analysed in the static and dynamic conditions. Since the dual phase steel is extensively used in the outer body parts of the automotive vehicles, its dynamic strength and plastic strain energy absorption during the crash are essential. D…
An optimum modern spinning methods achieving physiological comfort in circular weft knitting fabrics.
