Effect of temperature variation to product distribution, rate and deactivation of catalyst of tetrahydrifuran hydrodeoxygenation have been conducted using Pt/gAl2O3 with aluminum enrichmen. Reaction was conducted by flow system. Product of reaction were analyzed as propane (C3) and buthene derivate (C4). At 350ºC, rea…
The research on the effect of chloro acetic concentration and temperature reaction of carboxymethyl chitosan formation on cation exchange capacity and thermal stability of polymer have been done. Carboxymethyl chitosan was synthesized by reaction of chitosan and chloro acetic acid with NaOH as catalyst. Polymer was ch…
This document proposes a nomenclature for aluminium silicon oxide nitrides [In ceramic literature these compounds are generally called oxynitrides. According to IUPAC rules (cf. G. J. Leigh, ed. Nomenclature of Inorganic Chemistry. Blackwell Scientific Publishers, Oxford, UK (1990)) this is not allowed; the systematic…
Gelatin has been successfully extracted from chicken clawsby acid hydrolysis method through four major stages of degreasing, demineralization, extraction and drying. The yield of extracted gelatin obtained from wet chicken claws was about 6.21 % (w/w). The effectiveness of gelatin as preservative applied in beef and f…
The purpose of the research is to find out the synthesis, formula and characteristic of complex of Nickel(II) with hydantoin (hyd). Complex of nickel(II) with hydantoin have been synthesized in 1 : 1 mole ratio of metal to ligan in methanol.The formula of complex which are predicted from analysis of % Ni in complex by…
A Research on CdS synthesis in reverse microemulsion of Igepal CO-720 system has been conducted at various weight ratio of water to surfactant. Igepal CO-720 naturally forms oil in water (o/w) emulsion type due to its high HLB (Hydrophilic -Lipophilic Balance) value. Therefore, in this research the Igepal CO-720 syste…

In thin shell structures, like pressure vessels, high pressure ducts and aircraft fuselages, openings are invariably necessary. Circular openings in structural members are generally preferred in practice due to its simple geometry; but, from a purely structural point of view, there are other configurations which offer…
Utilization of iron ore-carbon composite enables to play a significant role in reducing CO2 emission from the ironmaking process. However, its efficiency seems to be limited under the condition of the blast furnace. In this study, the effect of pressure from 0.1 to 8.0 MPa on the gasification and reduction of the comp…
Flexible electronic devices require the integration of multiple crucial components on soft substrates to achieve their functions. In particular, memory devices are the fundamental component for data storage and processing in flexible electronics. Here, we present flexible MgO barrier magnetic tunnel junction (MTJ) dev…

Baja karbon rendah SPCC-SD dengan standar JIS G3141 merupakan jenis baja yang digunakan untuk pembuatan struktur baja, pipa, otomotif dan fabrikasi lainnya. Baja karbon rendah ini memiliki sifat mekanik yang baik. Akan tetapi baja ini dapat mengalami korosi yang tidak dapat dicegah. Salah satu cara memproteksi baja da…
The Rolling mill roll deformation is a serious problem and directly impact on production capacity, Mill Environment, Quality and highly impacting financial viability of the production companies. In this research paper the data taken from three companies, Supreme Rolls and Shears Pvt Ltd Indore, Dee Tee Industries Indo…
Let $μ_2(G)$ be the second smallest Laplacian eigenvalue of a graph $G$. The vertex connectivity of $G$, written $κ(G)$, is the minimum size of a vertex set $S$ such that $G-S$ is disconnected. Fiedler proved that $μ_2(G) \le κ(G)$ for a non-complete simple graph $G$; for this reason $μ_2(G)$ is called the "algebraic…
The concept of tall structures is not new to the world, yet the trend of high-rise construction started in the nineteenth century. High-rise or multi-storey buildings are being constructed either to cater for a growing population or as a landmark to boost a country’s name and get recognition. Any structure, to be reli…

We report the successful formation of bulk insulating ternary topological insulators candidate Bi2Se2Te (BST) by pulsed laser deposition technique. The films were deposited with sequential ablation of separate Bi2Se3 (BS) and Bi2Te3 (BT) targets. From the X-ray diffraction analysis and temperature dependent resistivit…
Let $A$ and $B$ be arbitrary $C^*$-algebras, we prove that the existence of a\nHilbert $A$-$B$-bimodule of finite index ensures that the WEP, QWEP, and LLP\nalong with other finite-dimensional approximation properties such as CBAP and\n(S)OAP are shared by $A$ and $B$. For this, we first study the stability of the\nWE…
Recent measurements of spin Hall effect (SHE) in chemically treated graphene, reporting unexpectedly large charge-to-spin conversion efficiency, have raised a fierce controversy. Here, using efficient implementations of numerically exact Kubo and Landauer-Buttiker formulas, we analyze the SH conductivity, the nonloca…
Resumo A exposição de filmes adesivos de resina epoxídica à temperatura ambiente propicia condições que afetam diretamente suas propriedades físicas. Para o adesivo estrutural AF191, de aplicação no setor aeronáutico, isto pode ser confirmado pela súbita perda de pegajosidade (“tack”). Sendo assim, o comportamento do…
