Selenium-doped Calcium Carbonate Nanoparticles

Se-doped and lipid-coated calcium carbonate nanoparticles loaded with cisplatin (Pt/[email protected] 3 NPs) were prepared by a reverse microemulsion method. The NPs delivered cisplatin and Se to tumour cells at an optimal synergistic ratio of 1:1 (mol/mol) both in vitro and in an osteosarcoma xenograft model.

Application of Box-Behnken design to prepare gentamicin ...

(4)d Drug Applied Research Center and Faculty of Pharmacy, Tabriz University of Medical Sciences, Tabriz, Iran. The aim of this research was to prepare and optimize calcium carbonate (CaCO3) nanoparticles as carriers for gentamicin sulfate. A chemical precipitation method was used to prepare the gentamicin sulfate-loaded CaCO3 nanoparticles.

Methods: A microemulsion method was employed to generate lipid coated cisplatin/oleanolic acid calcium carbonate nanoparticles (CDDP/OA-LCC NPs), and the loading concentration of CDDP and OA was measured by atomic absorption spectroscopy and HPLC respectively.Transmission electron microscopy (TEM) was used to examine the nanoparticles morphology while its pH dependent release

Calcium Carbonate Nanoparticles; Potential in Bone and ...

Drug loaded calcium carbonate nanoparticles For the preparation of drug loaded calcium carbonate nanoparticles, drug can be wrapped into the nanoparticles in the process of the reaction. For example, Ueno et al prepared the calcium carbonate nanoparticles loaded with betamethasone phosphate

The Use of Calcium Carbonate in Polyolefins Offers ...

[1,2,3 ] One of the key properties of calcium carbonate that offers increased output when added to polyolefins is thermal conductivity. The thermal conductivity of calcium carbonate is 2.7 W/(m *K) as compared to less than 0.5 for neat polyolefin resins. This increased thermal conductivity of calcium carbonate loaded polyolefins

Formulation of a Sustained Release Docetaxel Loaded

Here, we explored the formulation of a calcium carbonate nanoparticle delivery system aimed at enhancing docetaxel (DTX) release in breast cancer. The designed nano- anticancer formulation was characterized thorough X-ray diffraction (XRD), Fourier transformed infrared (FTIR), transmission electron microscopy (TEM) and field emission scanning electron microscopy (FESEM) and Brunauer-Emmett

5 Reasons to Use Calcium Carbonate Filled Polypropylene

10-02-2017  The addition of calcium carbonate to polypropylene sheet has been shown to improve the performance of the plastic across the board. At just an 18% loading, studies performed by Heritage Plastics showed that the calcium carbonate improved several key properties.

Calcium carbonate - Wikipedia

Calcium carbonate is a chemical compound with the formula Ca CO 3.It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of eggshells, snail shells, seashells and pearls.Calcium carbonate is the active ingredient in agricultural lime and is created when ...

106 cockle shell-derived calcium carbonate (aragonite) nanoparticles for curcumin delivery. 107 108 The present study aimed to synthesize and evaluate the in vitro kinetic release mechanisms of 109 Cur-CSCaCO 3 NP. The development of CSCaCO 3 NP as a potential nanocarrier for curcumin delivery 110 was conducted using simple top down method.

Sound Barrier/MLV-FAQs dispels the myths about MLV

It is essentially a viscoelastic material, such as polyvinylchloride (PVC, or vinyl), that is loaded with an inert material, such calcium carbonate or barium sulfate. Viscous materials, such as honey, when subjected to a force, will flow and take on a different shape.

Loading of Porous Functionalized Calcium Carbonate ...

The physical nature of the loaded substances is critical for the deposition within the pores of functionalized calcium carbonate. We conclude, that a combination of mercury intrusion porosimetry and focused ion beam scanning electron microscopy allows for a reliable analysis of sub-micron porous structures of particulate drug carriers.
