Abstract

An extraordinary mud volcano, commonly referred to as LUSI or Lumpur (mud) Sidoarjo, erupted in May of 2006 in Sidoarjo, East Java. Since then, LUSI has claimed approximately 700 hectares of rice fields, factories, villages and other infrastructures. A bold attempt to reduce the volume of mud by inserting sets of high density chained balls (HDCB) has been tried by a team of scientists and engineers from Bandung Institute of Technology. This effort requires, among others, measurement of LUSI’s physical properties (temperature, density, water content, viscosity, magnetic susceptibility, etc.) as a part of its evaluation and monitoring system. We will describe how this challenging task was performed. The environment in which the samples were obtained is harsh as the in situ temperature of the mud is about 90 degree centigrade, the ground in unstable, and the presence of water vapor with high content of H2S. In general, mud samples were collected on daily basis during the HDCB insertion. The results of these measurements of physical properties are valuable in assessing the effectiveness of the HDCB operation.

Abstract

Study on thorium fuel cycle with free 233U in boiling water reactor (BWR) has been carried out. In this study we have utilized plutonium and minor actinides (MA) as fissile nuclides instead of 233U as one of the main scenario to obtain the 233U free BWR core with thorium. Beside that, the void-fraction of the reactor is modified from 20% up to 70%. The results show that the standard BWR core can maintain its criticality when the loaded fuel is thorium with 11.16% and 1.24 % of plutonium and MA, respectively. The use of 11.16% of Pu and 1.24 % of MA is more than enough to substitute the 1% of 233U to obtain thorium fuel cycle in the standard BWR with free 233U. Moreover, the lesser amount of plutonium and minor actinides in the fuel will results in the great degradation on the safety of reactor

Abstract

Derivation of the transmittance of an electron incident on a heterostructure potential with nanometer-thick trapezoidal barrier grown on anisotropic materials is done by solving the effective-mass equation including off-diagonal effective-mass tensor elements. The analytic expressions are applied to the Si(110)/Si0.5Ge0.5/Si(110) heterostructure. It is assumed that the direction of propagation of the electrons makes an arbitrary angle with respect to the interfaces of the heterostructure and the effective mass of the electron is position dependent. The calculation of transmittances is done for incident energy at z direction below and above the barrier height by varying the applied voltage to the barrier. The maximum transmittance depends on the incident energy and the bias voltage given to the potential barrier. The transmittance value obtained from the Airy function has the same value obtained from the transfer matrix method. It was also found that the transmittance depends on the valley and it is not symmetric with the incident angle.

Abstract

Oscillations in granular gas are observed and experimental results show, that there is a cooperation between dynamics coefficient of restitution and density ratio simultaneously, which decides whether a binary mixture could experience an oscillation or not.

Abstract

We explored the use of Nd1+xBa2-xCu3O7 (x = 0.12) as target material during sputter deposition. Adjustment of the growth parameters such as growth temperature and partial oxygen pressure on the effect of surface roughness, crystallinity, and electrical properties of thin films on SrTiO3 as well as MgO substrates have been studied. The microstructure of Nd1.12Ba1.88Cu3O7-δ thin films was observed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM). In order to reduce precipitation on the films, we use special SrTiO3 substrate treatment or applied a buffer layer on MgO substrates, resulting in smooth Nd1.12Ba1.88Cu3O7-δ thin films. Furthermore, the smoothness of a ramp-edge (created by Ar-ion beam etching) is studied. Structuring of the ramp in tri-layer of Nd1.12Ba1.88Cu3O7-δ/SrTiO3/PrBa2Cu3-xGaxO is performed using a standard photolithography process.
