Effective microchip extraction of deoxyribonucleic acid (DNA) from crude biological matrixes has been demonstrated using silica beads or hybrid phases composed of beads and sol-gel. However, the use of monolithic sol-gels alone for extraction of human genomic DNA has been more difficult to define. Here we describe, for the first time, the successful use of monolithic tetramethyl orthosilicate-b...

in the present study, the interactions of three different lithium species li+, li3+ and ch3li with several different sites of the most stable tautomers of dna nucleo-bases are presented. this investigation is based on the results of thermochemical properties, quantum theory of atoms in molecules (qtaim) and natural bond orbital (nbo) analysis, obtained at b3lyp/6-311++g(d,p) level of theory. th...

These experiments examined the effects of pre-test intra dorsal hippocampus (intra-CA1) administration of GABAA receptor agonist and antagonist, muscimol and bicuculline respectively, on state-dependent learning induced by lithium. Male NMRI mice were trained in a one-trial step-down inhibitory avoidance task, and immediately after training they received IP injections of either saline (10 mL/kg...

The dissolution kinetics of silica-containing minerals in aggregates influences strongly the process ASR concrete. In this paper, effect different ions on rates SiO2 (amorphous and quartz) feldspars at high pH values was studied by following increase silicon concentrations experiments with a novel approach measuring evolution scratches polished surfaces. second method avoided problem precipitat...

Large-scale high-energy batteries with electrode materials made from the Earth-abundant elements are needed to achieve sustainable energy development. On the basis of material abundance, rechargeable sodium batteries with iron- and manganese-based positive electrode materials are the ideal candidates for large-scale batteries. In this review, iron- and manganese-based electrode materials, oxide...

Changes in the amounts of thylakoid galactolipids and proteins were monitored for 96 hours following iron resupply to iron-deficient sugar beet (Beta vulgaris L. cv F58-554H1) plants. During this period of iron nutrition-mediated chloroplast development, the amount of galactolipid per leaf area increased linearly with time. Assuming galactolipids are an index for the amount of thylakoids, then ...

Highly ordered short-channel mesoporous silica SBA-15 with large pores (11.2 nm) was synthesized from tetramethyl orthosilicate, using the block copolymer Pluronic PE-10400 as structure-directing agent, and triisopropylbenzene a swelling agent.
