BACKGROUND Researchers are looking for biomimetic mineralization of ena/mel to manage dental erosion. This study evaluated biomimetic mineralization of demineralized enamel induced by a synthetic and self-assembled oligopeptide amphiphile (OPA). RESULTS The results showed that the OPA self-assembled into nano-fibres in the presence of calcium ions and in neutral acidity. The OPA was alternate...

The present in vitro study created nanometer crystalline hydroxyapatite (HA) and amorphous calcium phosphate for novel orthopedic applications. Specifically, nano-crystalline HA and amorphous calcium phosphate nanoparticles were synthesized by a wet chemical process followed by hydrothermal treatment for 2 hours at 200 degrees C and 70 degrees C, respectively. Resulting particles were then pres...

Duck eggshells are one of bio-wastes from poultry industry and household that have been disposed. contain high calcium which can be applied as an alternative source daily for the body. Nanostructured duck eggshell used a food additive in beef sausage processing. This study was conducted to determine chemical quality fortified by nano-calcium. The materials include beef, soy protein isolate, pal...

Introduction: Development of new pulp capping agents has paved the way towards the preservation of pulp vitality, which is an important goal in restorative dentistry. This study sought to assess the calcium ion release, pH and setting of mineral trioxide aggregate (MTA) Angelus, an experimental formulation of nano-hybrid MTA containing nano-SiO2, nano-Al2O3 and nano-TiO2 and MTA Angelus plus na...

In order to investigate the effect of humic acid (HA) and nano-calcium chelate on the cut flowers of gerbera cv. Dune, an experiment was performed as a completely randomized design with two factors and three replications in hydroponic conditions. The first factor included humic acid at 4 concentrations of 0 (control), 500, 1000, and 2000 mg L-1 as drench and the second factor was ass...

PURPOSE This research aims to study the influences of heparin (HP) on the aggregation of nano calcium oxalate monohydrate (COM) and nano calcium oxalate dihydrate (COD) with mean diameter of about 50 nm. METHOD The influences of different concentrations of HP on the mean diameter and Zeta potential of nano COM and nano COD were investigated using a nanoparticle size Zeta potential analyzer. ...

The calcium ferrite nano-particles (CaFe2O4 NPs) were synthesized using a sol-gel method for targeted drug delivery application. The proposed nano-particles were initially prepared by mixing calcium and iron nitrates that were added with citric acid in order to prevent agglomeration and subsequently calcined at a temperature of 550°C to obtain small particle size. The prepared nanoparticles wer...

Polypropylene is extensively used for varied applications due to its low cost, low density, high thermal stability and resistance to corrosion. Enhanced mechanical properties of Polypropylene can be achieved by mixing it with clays to form nanocomposites which increases its utility. Polypropylene Nano composites are formed by mixing polypropylene with calcium carbonate nano particles. This resu...

This study aimed to investigate the effect of nano-Ca fertilizer on nitrogen uptake, use efficiency and determine best calcium form dose for mango. A pot experiment was conducted using two year old mango seedlings (cv. Zebda). The pots were filled with sandy soil (8 kg per pot) one seedling transplanted into each pot. Four treatments including nano-Ca, convention Ca, application foliar have bee...
