Novel lipid nanoparticulates (NCs) were developed by a combined approach of precipitation and complexation with an aim to improve the solubility, stability and targeting efficiency of glimepiride (GLP). GLP NCs were prepared by precipitation process using PEG 20000 and further complexed with phospholipon90G (P90G). The NCs were evaluated for physicochemical characterization, such as drug lo...

Efavirenz belongs to Class II under BCS and exhibit low and variable bioavailability due to its poor aqueous solubility. As such it needs enhancement in the dissolution rate and bioavailability to derive its maximum therapeutic efficacy. The objective of the present investigation is to study the complexation of efavirenz with two cyclodextrins, βcyclodextrin (βCD) and hydroxypropyl β-cyclodextr...

      Calcium acetate is used as an oral phosphate binder to control hyperphosphatemia in patients with chronic renal failure. Compared to calcium carbonate, control of hyperphosphatemia can be achieved at lower calcium administration with calcium acetate which likely reduces the risk of hypercalcemia. In this study, various formulations of calcium acetate tablets were prepared and their disint...

The solubility of pristine fullerenes can be enhanced by mixing C60 and C70 due to the associated increase in configurational entropy. This "entropic dissolution" allows the preparation of field-effect transistors with an electron mobility of 1 cm(2) V(-1) s(-1) and polymer solar cells with a highly reproducible power-conversion efficiency of 6%, as well as a thermally stable active layer.

A membrane-less organic-inorganic flow battery based on zinc and quinone species is proposed. By virtue of the slow dissolution rate of the deposited anode (<11.5 mg h-1 cm-2), the battery has a cell voltage of ca. 1.52 V with an average energy efficiency of ca. 73% at 30 mA cm-2 over 12 cycles.

BACKGROUND Advances in techniques have left very few indications for open surgical extraction of urinary stones currently. These advances notwithstanding, the search continues for medical approaches to urinary stone management. In this study, we perform an in vitro study analyzing the efficiency and prospect of two new complex solutions in urological calcium phosphate calculi dissolution. MET...

Carbon dioxide (CO2) dissolution is the secondary trapping mechanism enhancing long-term security of CO2 in confined geological formations. injected into a randomly multilayered formation will preferentially migrate along high permeability layers, increasing efficiency. In this study, sequential Gaussian simulation adopted to construct stratified saline formations, and two-phase flow based on M...
