Calcium carbonate nano-particles were synthesized by a reverse micro-emulsion method at room temperature with Tween® 80 and Span® 80 as co-surfactants. The nano-particles synthesized were surface modified by stearic acid. An important operating variable in the Span 80-Tween 80/toluene/water reverse micro-emulsion system, the ω-value (water/surfactant molar ratio) was i...

A breakthrough has been discovered in pathology chemistry related to increasing molecular structure that can interfere with oxygen diffusion through cell membranes. Free radicals can crosslink unsaturated low-viscosity fatty acid oils by chain-growth polymerization into more viscous liquids and even solids. Free radicals are released by mitochondria in response to intermittent hypoxia that can ...

objective(s): so far, extensive research has been conducted on the preparation and characterization of nano ceramics based on ca-si by sol- gel method and bioactivity was evaluated, but, a few researches have paid attention to the preparation of materials by mechanical activation (ma). the aim of this study was the preparation of akermanite nano powder by mechanical activation method and bioact...

In our work, the influence of coordination environment Ca atom states in biomimetic mineralizing composite dental materials integrated with tissue was investigated. Biomimetic composites as well natural samples were investigated using synchrotron X-ray absorption near edge structure (XANES) spectroscopy. Energy studies revealed a number important features related to different type calcium envir...

Since the use of systemic antibiotics for preventing acute biomaterial-associated infections (BAIs) may build up bacterial resistance and result in huge medical costs and unpredictable mortality, new precaution strategies are required. Here, it demonstrated that titanium armed with a nano-thick calcium oxide layer was effective on averting methicillin-resistant Staphylococcus aureus (MRSA) infe...

Cement is one of the most produced materials in world. A major player greenhouse gas emissions, it main binding agent concrete, to which provides a cohesive strength that rapidly increases during setting. Understanding how such cohesion emerges has been obstacle advances cement science and technology. Here, we combine computational statistical mechanics theory demonstrate results from organizat...

Body organs are very crucial when it comes to homeostatically maintaining them. If any changes occur in their function, may lead the development of diseases body. The kidney is one functionalised that connected with ureter and urinary bladder, which basically lower part priorly controls volume various body fluids, fluid osmolality, acid-base balance, electrolyte concentrations, removal toxins. ...

nowadays, the use of innovative nano-technology in the food industry quality control has significantly increased and it is widely employed in numerous fields such as diagnosis of microbial toxin of foods using nano-biosensors, increasing food shelf-life with the help of nano-clay and nano-silver packaging, as well as changing some of the unpleasant organoleptic properties such as taste, color, ...

The use of synthetic hydroxyapatite as bone substitute calls for the knowledge of the influence on adjacent cells. The aim of this study was to investigate the proteins with differential protein expression levels in the proteome of human osteoblast cell line incubated separately with various nano sized hydroxyapatite powders with different shapes and chemical compositions using iTRAQ-coupled 2D...
