Temperatur dan gas belerang di aliran air sekitar sumber air panas dan gas belerang kawasan Gedongsongo Kabupaten Semarang, diduga mempengaruhi struktur komunitas diatom epilitik. Proses keluarnya gas belerang adalah melalui celah celah bebatuan sehingga belerang akan menempel pada bebatuan yang merupakan substrat dar…
The idea of generating electricity from ambient heat has significant meanings for both science and engineering. Here, we present an interesting idea of using pencil leads, which are made of graphite and clay, to generate electricity from the thermal motion of ions in aqueous electrolyte solution at room temperature. W…
背景：e-己内酯/D,L-丙交酯共聚物因具有良好的力学性能、降解性能以及生物相容性而受到广泛研究,但对其非等温结晶动力学研究相对较少.目的：了解e-己内酯/D,L-丙交酯共聚物的非等温结晶动力学性能.方法：以实验室自制的e-己内酯：D,L-丙交酯共聚物90：10 为观察对象,采用示差扫描量热仪对其进行非等温测试,观察其结晶行为.结果与结论：随着降温速率R的增加,PCDLA的结晶温度向低温方向移动,且Avrami指数均〉3,以均相成核的三维球晶方式生长;Jeziorny法和莫志深法研究结果基本一致.
In the context of high demand for energy in mobile devices, many studies deal with the lithium-ion cell technology. Because of its larger uptake ability of Li, silicon was suggested for being used (combined with a conductive material) instead of graphite, currently the most frequently used anode material for combining…
A glass ceramic waste form is being developed for treatment of secondary waste streams generated by aqueous reprocessing of commercial used nuclear fuel (Crum et al. 2012b). The waste stream contains a mixture of transition metals, alkali, alkaline earths, and lanthanides, several of which exceed the solubility limits…
According to the Wulff construction the shape of the equilibrium crystal is determined by the surface tension considered as a function of the interface orientation. We present some (conjectured) approximate solutions and some rigorous results concerning this function, in the case of a lattice gas, and apply them to st…
Few-layer graphene sheets were produced from graphite oxide (GO) chemical and thermal reduction. For the chemical reduction of GO as reducing agents were used hydrazine hydrate, hydroxylammonium chloride, sodium borohydride and sodium sulfite. The reduced material was characterized by elemental analysis, thermo-gravim…
Very recently, in the 2011 version of the Wien2K code, the long standing short come of the codes based on Density Functional Theory, namely, its impossibility to account for the experimental band gap value of semiconductors, was overcome. The novelty is the introduction of a new exchange and correlation potential, the…
Protein structures in 3D are large. elegant, complex, and subtle enough that their prediction and understanding still largely eludes us. In contrast, their local building blocks are quite simple: to a good approximation their connectivity is a tree graph of backbone and sidechains, and the atoms are connected with spe…

A multiferroic heterostructure composed of ( Bi 0.875 Nd 0.125) FeO 3 (BNF) are grown on ( Ba 0.65 Sr 0.35) TiO 3(BST) buffered Pt/Ti/SiO2/Si(100) substrate by rf-magnetron sputtering. The heterostructure BNF/BST exhibits a quite low leakage current (3.7 × 10-7 A/cm2 at 300 kV/cm) and dielectric loss (0.0036 at 100 kH…
The activity concentration of 226Ra, 232Th and 40K was determined in solid and liquid samples collected from the TSP Fertilizer Factory, Chittagong, Bangladesh. A total of 18 samples of seven different kinds (including liquid and solid wastes) were collected and analyzed by gamma ray spectrometry technique using a hig…
Ti-based body centered cubic (BCC) solid solutions are promising materials for hydrogen storage. These alloys are usually synthesized by melting processes and have large amounts of vanadium as alloying element to stabilize the BCC phase at room temperature. In this work high energy ball-milling was evaluated as proces…
The production and use of durable materials in construction are considered as one of the most challenging things for the professional engineers. Therefore, this research was conducted to investigate the mechanical properties and the durability by using of different percentages of steel fiber with high-strength flowabl…

Nano partikel magnetit telah disintesis dari pasir besi dengan menggunakan metode kopresitasi pada temperatur ruang dan dipanaskan. Struktur kristal, ukuran partikel dan sifat kemagnetan dikarakterisasi dengan XRD dan VSM. Hasil dari analisis didapatkan magnetit mengalami transisi fasa dan struktur pada temperatur 500…
Designing self-assembling peptides as nanomaterials has been an attractive strategy in recent years, however, these peptides were usually studied in aqueous solutions for their self-assembling behaviors and applications. In this study, we have designed a surfactant-like peptide AGD with a wedge-like shape and studied…
Carbon steel pipelines are used extensively in the oil and gas industry for sub-sea applications. Usually they are cathodically protected and have exterior surface protective coatings. Where these are ineffective or not used, the evolution of weld zone corrosion with time may be of interest. Experience has shown that…
