Research ArticleOpen accessIn the abstractCold Crystallization Behavior of a Zr44-Ti11-Cu10-Ni10-Be25 Metal Glassy AlloyRaffaella Aversa, Daniela Parcesepe, Francesco Tamburrino et al.Liquid crystals, a substance that flows like a liquid but has some degree of ordering in the arrangement of its molecules. "Depending on temperature or the presence of an electric potential difference, molecules in a liquid crystal can either be randomly, partially or completely aligned."Isothermal cycles of the metalized metallic alloy Zr44-Ti11-Cu10-Ni10-Be25 (cold crystallization obtained by heating the glassy glass … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 19 Jun 2018 · 8,184 accessesView PDFCite
Review ArticleOpen accessIn the abstractBiomechanically Inspired Machines, Driven by Muscle Like Acting NiTi AlloysAntonio Apicella, Raffaella Aversa, Florian Ion Tiberiu PetrescuThe Shape of the Memory Alloy (SMA) is a very promising class of metallic materials with interesting non-linear properties such as Pseudo-Elasticity (PE), memory (MEM) and damping capacity due to high mechanical hysteresis and internal friction. Research shows a bioinventory approach to Shape Memory Alloy (SMA) design, a class of intelligent materials capable of reacting to a pulse (thermal for … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 23 May 2018 · 8,279 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction and Evaluation of Hydroxyapatite (HAp) Properties of Broiler’s Composite Bone (BCB) Waste at Different Sintering TemperaturesMuhammad Irfan Said, Effendi Abustam, Asdar Gani et al.Bone is one of the perishable livestock wastes, so serious attention is needed. The wastes are produced by Poultry Slaughterhouse (PSh) primarily in the process of separating meat from bone to produce boneless products. The main constituent of bone is the crystals Ca and P, which are the major elements of Hydroxyapatite (HAp). The purpose of this study was to … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 8 May 2018 · 7,711 accessesView PDFCite
Research NotesOpen accessIn the abstractA Study on Fabrication and Structural Characterization of PbS Thin FilmsMustika Wati, Kamsul AbrahaPbS thin films are fabricated from 99.9% PbS powder on glass substrates using the vacuum evaporation method. Some of the samples are then treated in an advanced process called annealing. Samples are annealed in temperatures of 80, 100, 120 and 150°C for two h. Characterization using an X-Ray Diffractometer (XRD) resulted in values of lattice constant of the films ranging … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 20 Nov 2017 · 7,847 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimple Fabrication and Characterization of Piezoelectric Nanogenerators from Cobalt-Doped Zinc Oxide NanofibersSuyitno, Syamsul Hadi, Mohd Zainizan Sahdan et al.The ferromagnetic cobalt doped into Zinc Oxide (ZnO) crystals is a promising method for enhancing the performance of Piezoelectric-Based Nano Generators (PENGs). The study reports the characterization and testing PENGs which simply fabricated from cobalt-doped ZnO nanofibers (NFs) synthesized by electro spinning machine. The electro spinning processes were conducted at a flow rate of 4 μL/min and at various cobalt … …American Journal of Applied Sciences, Vol. 14, Issue 7 · 29 Jul 2017 · 8,173 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreventive Effect of Marsileacrenata Leaves and Stalks Juices Against Urolithiasis Showed by Improving of Kidney FunctionSri MurwaniNowadays urolithiasisis still as a major problem in pet animals, particularly for dogs and cats. Urolithiasisis caused by formation of crystals in the urinary tract that inhibit the process of urination. It is frequently as an impact of dry food given regularly, keeping animals in a place so that the movement of the animal becomes restricted, lack of water intake, … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 1 · 10 Feb 2016 · 9,305 accessesView PDFCite
Research ArticleOpen accessIn the abstractRaman Spectroscopy of Protein Crystal Nucleation and GrowthPechkova Eugenia, Maksimov, Georgy et al.Using Raman spectroscopy and the lysozyme as model system, we investigate the differences in protein conformation before and after Langmuir-Blodgett nanotemplate-induced crystal nucleation and growth. It was found, that the main difference in lysozyme conformation is associated to the higher amount of S-S bonds in lysozyme of LB crystals, probably in C-end of protein, resulting in the higher stiffness of … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 3 · 8 Dec 2014 · 8,275 accessesView PDFCite
Research ArticleOpen accessIn the abstractDIFFERENT APPROACHES TO CRYSTALLIZATION OF MEMBRANE PROTEINSPrakash G. Doiphode, Vivek Pratap SinghCrystallography is more like an art than science. Crystallizing membrane proteins are a big challenge; membrane proteins are present in the cell membrane and serve as cell support. The most important feature of membrane protein is that it contains both hydrophobic and hydrophilic regions on its surface. They are generally much more difficult to study than soluble proteins. The problem … …OnLine Journal of Biological Sciences, Vol. 12, Issue 3 · 18 Dec 2012 · 7,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultilevel Evaluation of Coulomb Lattice Sums of Charge SystemsV. Ilyin, A. Brandt, I. SuwanProblem statement: Due to the long range nature of interactions of the N-body systems, direct computation of the Coulomb potential energy involves O(N2) operations. To decrease such complexity, a simple Multilevel Summation method has been developed. Approach: In the frame of the Multilevel Summation method, the two-body interaction is decomposed into two parts: a local part and a smooth part. … …Journal of Mathematics and Statistics, Vol. 8, Issue 3 · 11 Sep 2012 · 7,377 accessesView PDFCite
