Research ArticleOpen accessIn the keywordsNanoscale Pitch Standards Sample Fabricated using Laser-Focused Atomic DepositionYan Ma, Tongbao Li, Yajun Zhao et al.Problem statement: Nanotechnology is already a large sector of industry and science research and it is expected to continue to grow at very fast rate. The determination of absolute measurements of length at the nanometer scale and below is very difficult and expensive. So the nanoscale metrology standard is needed. Approach: The laser-focused atomic deposition is a new way to … …Current Research in Nanotechnology, Vol. 2, Issue 2 · 3 Sep 2012 · 7,249 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessment of Heavy Metals Migration in the Water - Soil - Fodder - Milk Food Chain in the Almaty RegionNurzhan Sarsembayeva, Tolkyn Abdigaliyeva, Zura Utepova et al.This study presents the results of monitoring heavy metals (Cd, Pb, As and Hg) in the water - soil - fodder - milk food chain. The research aimed to study the effect of lead, cadmium, mercury and arsenic in soil, water and components of the diet of cattle on their bioaccumulation in livestock products (milk) in basic farms of the … …OnLine Journal of Biological Sciences, Vol. 21, Issue 2 · 22 Jun 2021 · 6,411 accessesView PDF Cite

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 · 8,193 accessesView PDF Cite

Review ArticleOpen accessIn the abstractBuses Running on GasRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.Today, the transport problem is not only very diverse and complex but also highly disputed in terms of the optimal way of achieving modern and ecological transports. The energy and social crisis that occurred in the 1970s and 1980s, which then haunted the planet repeatedly, becoming a major crisis, could be successfully avoided by postponing and reprogramming until mankind managed … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 6 Feb 2018 · 7,537 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIdentification of Pharmacological Targets Combining Docking and Molecular Dynamics SimulationsIlizaliturri-Flores Ian, Rosas-Trigueros Jorge Luis, Carrillo-Vazquez Jonathan Pablo et al.Studies that include both experimental data and computational simulations (in silico) have increased in number because the techniques are complementary. In silico methodologies are currently an essential component of drug design; moreover, identification and optimization of the best ligand based on the structures of biomolecules are common scientific challenges. Geometric structural properties of biomolecules explain their behavior and interactions and … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 1 · 21 Mar 2013 · 8,130 accessesView PDF Cite

Research ArticleOpen accessIn the abstractQuantum Mechanical Calculation of the Optical Absorption of Silver and Gold Nanoparticles by Density Functional TheoryElham Gharibshahi, Elias SaionProblem statement: Metal nanoparticles confine the motion of conduction electrons and exhibit a strong optical absorption of electromagnetic radiation in the UV-vis-NIR region. The absorption is classically derived from the collective oscillations of free electrons in a metallic nanostructure as a consequence of incident electromagnetic radiation polarizing the particle optically embedded in a dielectric matrix. These oscillations, known as the … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 16,193 accessesView PDF Cite
