Abstract:

In Western literary tradition, alienation is a common theme. This theme has been identified since the Shakespearean era. Yet, in Indonesian literary tradition alienation is a novelty. This paper aims at analyzing the emergence as well as the significance of this theme in the Indonesian context. In Western context, alienation occurs within the absence of God or within the materialistic society while in Indonesian context, in this case in Perempuan Berkalung Sorban, it occurs in a strong religious atmosphere. The main character, Anisa experiences alienation caused by the interpretation of religi

Abstract:

Cross-linked metal-imprinted Carboxymethyl Chitosan-Pectin (CMC-Pec) were prepared from CMC and pectin, using Pb (II) ion as a template and Bisphenol A diglycidil ether (BADGE) as the cross-linking agent. The film was prepared in order to obtain a selective adsorbent for Pb (II) ion. The film was characterized using infrared (IR) spectroscopy. The result showed that the active group of the Pb (II)-imprinted CMC-Pec-BADGE film was hydroxyl group (-OH) and carboxylic (-COOH) as indicated by IR peaks at the wave number 3300-3600 cm-1and 1600-1800 cm-1, respectively.

Abstract:

An overview is given of the development of sorbent materials for hydrogen storage. Understanding the surface properties of the adsorbed film is crucial to optimize hydrogen storage capacities. In this work, the lattice gas model (Ono-Kondo) is used to determine the properties of the adsorbed hydrogen film from a single supercritical hydrogen isotherm at 77 K. In addition, this method does not require a conversion between gravimetric excess adsorption and absolute adsorption. The overall average binding energy of hydrogen is 4.4 kJ/mol and the binding energy at low coverage is 9.2 kJ/mol. The h

Abstract:

AbstractExpanded vermiculite with excellent thermal and chemical stability was investigated as a reliable sorbent for hazardous liquid spillages, including those leading to fire and explosion risks. Many expanded samples were prepared by rapid heating using both different temperatures and dissimilar vermiculite dimensions. Their capabilities for hazard clean-up were correlated with the structural characteristics of expanded vermiculite with slit-shaped porosity. When using optimized vermiculite, the moderate sorption capacities of 1.5–3.0 g g−1 were obtained for various hazardous chemicals, in

The dissolution of paper white mud(PWM) has been studied by pH-stat method in various parameters such as the pH values(4.3, 5.4, 6.0, 7.5), sorbent particle sizes (0-0.097mm, 0.097-0.105mm, 0.105-0.3mm), and the reaction temperature (30°C, 40°C, 50°C) in order to investigate the feasibility of using PWM as wet flue gas desulphurization sorbent. The results show that: the lower the pH value is, the higher the dissolution rate; particle size is the direct function of dissolution rate, the smaller the size is, the higher the dissolution rate, the optimal particle size in this work is 0-0.097mm; a

The interaction of different amino acids and vacuum evaporated tetraphenyl porphyrin films was investigated by using kinetic isotherms, UV-vis spectroscopy, quartz crystal microbalance and density functional theory techniques. The adsorption process was analyzed by using pseudo-first-order and pseudo-second-order models. From these results, the adsorption order changed depending on the chemical characteristics of the porphyrin film, although most of the interactions were classified as pseudo-second-order at the films interface. From absorbance measurements, red shifts on the Soret peak positio

Temporal and spatio-temporal instabilities of binary liquid films flowing down an inclined uniformly heated plate with Soret effect are investigated by using the Chebyshev collocation method to solve the full system of linear stability equations. Seven dimensionless parameters, i.e. the Kapitza, Galileo, Prandtl, Lewis, Soret, Marangoni, and Biot numbers (Ka,G,Pr,L, χ,M,B), as well as the inclination angle (β) are used to control the flow system. In the case of pure spanwise perturbations, thermocapillary S- and P-modes are obtained. It is found that the most dangerous modes are stationary for

Novel procedure of electrochemical chelation of polyimide films was developed. The kinetics of silver cation sorptions into the films during the chelation was found out. The effect of modification treatment of film surfaces on kinetics of electrochemical process was studied. The stabilization of ion-sorbed layer of films occurs in water-isopropanol solvents. Sorption of silver during electrochemical deposition is 0.75-1.5 mg per 100 μm of polyimide depending on modification solution. Thus, the most appropriate morphological modification with about 1.5 mg/100 μm take places in heterocyclic solv

Reversible preconcentration of all NMs was carried out using micro-column packed new PVBC-VP sorbent and elution with a mixture of thiourea, potassium thiocyanate, and HCl, which recovers Pd, Ir, Pt, and Au by 95% and Ru, and Rh by 90%. The proposed procedure was approved using certified reference materials.
