The thermal conductivity of Ge₂Sb₂Te? (GST) film and the thermal boundary resistance (TBR) between the film and the electrode strongly influence the performance of phase change memory. Especially, as the size of the device shrinks to nanoscale, the thermal conductivity of GST film becomes a function of the film thickn…
The present paper discusses the study of effect of corrosion protection on steel structure, effect of PH medium on steel structure and effect of deformation on corrosion rate in order to find the best solution for the corrosion problem. The objective of this is to experiment and analyze the corrosion behaviour of stee…
The magnetic properties of as-grown single-crystal SrMn3O6−δ nanoribbons synthesized by a simple molten-salt method can be significantly improved by a heat-treatment procedure, which enhances the ferromagnetism and spin-glass behavior. These enhanced properties might originate from a spin structure modulated by the th…
Abstract Na6[Ti5O12(OH)2] is the first structurally characterized sodium oxohydroxotitanate. The compound can be prepared via hydrothermal treatment of TiO2 (Anatas) in NaOH (10n) for 96 h at 250° in an autoclave. The crystal structure of Na6[Ti5O12(OH)2] consists of infinite ribbons $\rm{{_{\infty }^{1}}}$ [Ti5O12(OH…
The advancement of space exploration using nuclear science and technology has been a goal sought by many individuals over the years. The quest to enable space nuclear applications has experienced many challenges such as funding restrictions; lack of political, corporate, or public support; and limitations in education…

ABSTRAK Dewasa ini, pengelolaan pengetahuan nuklir di Badan Tenaga Nuklir Nasional (BATAN) telah menjadi kebutuhan yang mendesak. Kebutuhan pelestarian dan pewarisan pengetahuan nuklir tersebut dipicu oleh beberapa peristiwa yang terjadi akhir-akhir ini, seperti fenomena penuaan (ageing) pegawai BATAN, berkurangnya ma…
Abstract : The goal of this project was to increase rubber to metal adhesion in Army materials using the concept of functionally graded interfaces as observed in squid beaks. Through application of adhesive as a graded interface with layers of varying rigidity, exceptional adhesion can be accomplished. 3M Scotch-Weld…
One of the challenges that today's new workforce of nuclear criticality safety engineers face is the opportunity to provide assessment of nuclear systems and establish safety guidelines without having received significant experience or hands-on training prior to graduation. Participation in the International Criticali…
In this paper the physical properties of two types of Co-doped ZnO nanostructures: tetrapods and nanofibers grown by a rapid thermal evaporation process and prepared by the electrospinning technique, respectively, were investigated and analyzed. Surface morphology of the samples was examined using scanning electron mi…
Significance and UseCreep-fatigue testing is typically performed at elevated temperatures and involves the sequential or simultaneous application of the loading conditions necessary to generate cyclic deformation/damage enhanced by creep deformation/damag
Plastics Engineering is the official publication of the Society of Plastics Engineers (SPE). We provide plastics professionals with a wealth of information about machinery, technological advances, materials innovations, sustainability, and more.
The performance of laser ablation generated debris control by means of open immersion techniques have been shown to be limited by flow surface ripple effects on the beam and the action of ablation plume pressure loss by splashing of the immersion fluid. To eradicate these issues a closed technique has been developed w…
The thermal decomposition of ZnAl-hydrotalcite-like compounds (ZnAl-HTLcs) was studied using the TG-DTG method. It was shown there was a single mass loss stage of the thermolysis. The kinetics parameters of thermolysis were calculated by the Freeman – Carroll method, and the mechanism function was studied by the Šativ…
Micro structuring of sapphire and fused silica [1] is an important market e.g. the production of microfluidic devices and sensors that combine optical and microfluidic functions [2] as well as freeform microlense systems. New techniques which enable the processing of sapphire and fused silica are requested. The In-vol…
Surface treatment by means of fibre laser radiation using various processing gas compositions was conducted on cold isostatic pressed (CIP) Si3N4 and ZrO2 engineering ceramics to observe changes in their surface integrity, chemical composition and distribution of the heat affected zone (HAZ). The as received and fibre…
Laser Assisted Machining (LAM) of ceramics is an important area of manufacturing to improve the material removal rate and provide more geometric features that can be economically added to fully dense blanks over conventional course, intermediate, and fine diamond grinding. The challenges associated with the machinabil…
In this paper, two Adaline-based schemes for identifying the harmonic currents generated by nonlinear loads in power distribution systems are presented. Each neural method is based on formalized expressions of the active and reactive instantaneous powers. In both methods, the expressions of the instantaneous powers ar…
A homogeneity range of the PrFe11 − x Ga x C y phase was determined. As the gallium content increases, the lattice parameters were shown to increase, whereas the Curie temperature decreases; the type of magnetic anisotropy at room temperature is unchanged. In the alloys with x > 3, the transformation of the tetragonal…
In order to control the ion density and energy distribution in the vicinity of plasma sheath independently, the inductively coupled plasma and its glow discharge mechanism in the vicinity of plasma sheath were studied by means of optical emission spectroscopy (OES) under different RF power, different discharge and dif…
