Water delivery

This study aimed to design a nanocarrier system for the efficient delivery of poorly soluble drugs in cancer treatment. Nanogel systems were prepared from copolymers of Heparin and different Pluronics, in which the Hep-Plu conjugates were formed via disulfide bridges of cystamine molecules. The obtained Hep-Plu systems were proved and characterized using specific techniques including H-NMR, zeta potential, DLS and FT-IR.

In this work, collagen extracted from fresh-water fish scales has been used as a matrix in the drug delivery polymeric system. Allopurinol has been applied to reduce the concentration of uric acid in blood and used as a model drug in collagen drug delivery system. The functional groups in collagen/allopurinol biocomposite as well as the morphology of this material were assessed by infrared (IR) spectroscopy and scanning electron microscopy (SEM).

Emulsification method is one of the popular methods for producing materials used in biosensing, bioimaging and others, especially, drug delivery polymer systems in microsize and nanosize. The concrete techniques related to this method are emulsification, self-emulsification, in a combination with solvent evaporation process, homogenization, or ultranosication.

The metal-organic framework MIL-100(Fe) was synthesized by the green process using the ultrasonic method and water. By using this approach, the energy consumption was reduced by 100 times compared to the hydrothermal method. The prepared MIL-100(Fe) was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and BET surface area measurements.

Celecoxib is a poorly water-soluble nonsteroidal anti-inflammatory drug. Here we report four ordered mesoporous silica MCM-41 supports with different particle size, pore volume, and surface properties to investigate their loading capacity with celecoxib and their release abilities. Spherical MCM-41 mesoporous supports less than 50 nm in diameter were prepared and to compare the effect of the template removal process on morphology of samples, acid extraction and calcination methods were used.

Carbon nanotubes have emerged as highly promising theranostic agents due to their unique structural/physical features, high surface area, and high drug-loading capacity. The high cytotoxicity of carbon nanotubes can be eliminated by noncovalent coating using hydrophilic polymers. We investigated the adsorption of long pyrene functionalized polyethylene glycol (PEG) chains, PEG2000 and PEG5000 , on a single-walled carbon nanotube (SWNT) from a crowded solution.

Polyethylene glycol (PEG) is a polymer that is widely used as a carrier for drug delivery systems (DDS). A library of N-PEGylated quinoline derivatives of PEG molecular weight 200 was prepared rapidly after the activation of PEGs using maleic anhydride. Quinoline with a polymer backbone is essential as new material. PEG is a water-soluble nonionic polymer approved by food and drug organizations for medicine applications. Because of its nontoxic grapheme, it is widely utilized in numerous biochemical, cosmetic, pharmaceutical, and industrialized applications.

To improve bioavailability and stability of hydrophobic and hydrophilic compounds, nanoemulsions are good alternatives as delivery systems because of their nontoxic and nonirritant nature. Glutathione (GSH) suffers from low stability in water, where its encapsulation in nanoemulsions is a powerful strategy to its stability in aqueous systems. The aim of this study was to obtain nanoemulsions from the hydrophobic/hydrophilic contents of N. sativa seed oil so as to improve GSH stability along with bioavailability of N. sativa seed oil.

Pumping system powered by kinetic energy of water from nearby nallah can be a cheap, efficient and precise way of delivering water to nearby farm pond/open well. The pumping system is simple to develop, install, operate and very much cater to the need of rural remote area. It may be suitable for un-electrified as well as unreliable electric supply area provided suitable site conditions are available. The major components of spiral tube water wheel pumping system include rim, inlet valve, housing, flexible pipe, bearing, T-joint etc.

This paper presents the experiment results of the cycle work and overall performance of a new design of delivery valve in hydraulic ram. A hydraulic ram comprises of two non-return valves. They are well known as waste and delivery valves. Both mechanism propagate water hammer in cycle work of the hydraulic ram. In early designs, the water flow phenomenon occurring in the hydraulic ram operating process must be fully recognized for further analysis.

The aim of the present study was to develop and evaluate a thermoresponsive depot system comprising of docetaxel-loaded cubosomes. The cubosomes were dispersed within a thermoreversible gelling system for controlled drug delivery. The cubosome dispersion was prepared by dilution method, followed by homogenization using glyceryl monooleate, ethanol and Pluronic® F127 in distilled water. The cubosome dispersion was then incorporated into a gelling system prepared with Pluronic® F127 and Pluronic® F68 in various ratios to formulate a thermoresponsive depot system.
