BI-GELS: A NOVEL MATERIAL FOR TRANSDERMAL DRUG DELIVERY

Bi-gels semi solid formulation is combination of organogel and hydrogel with better application property such as pharmaceutical and cosmetics. The main objective of this review is specially focuses on application of bi-gels as drug delivery vehicles by transdermal route. It contains two different phases which are polar and nonpolar due to which, it possess some significant features such as ability to deliver the hydrophilic and hydrophobic drugs which also have improved permeability of drugs, better spreading ability, and water wash ability. Hence, bigels have both organogels and hydrogels they can enhanced hydration of stratum corneum and also had an ability to manipulate the drug release rate from the dosage from.

Rheological properties of oil–water Pickering emulsion stabilized by Fe3O4 solid nanoparticles

Pickering emulsions have attracted extensive attention due to their good properties including easy to manufacture, high stability, and superparamagnetic response. To improve the emulsifying transportation of crude oil, a Pickering emulsion of crude oil and water stabilized by Fe3O4 nanoparticles was prepared and its rheological properties were tested in this research. It was found that the particle size of dispersion droplet polymerization group in stable crude oil Pickering emulsion is negatively correlated with solid content and water content, and the equilibrium apparent viscosity {\mu }_{\text{ap}} of emulsion follows the power law fluid equation. Besides, this kind of Pickering emulsion has higher elasticity of interface membrane, which means by adding functional particles, it obtains good dynamic stability, and thus, has a great application property in crude oil industry.

THE IMPROVEMENT OF BITUMEN APPLICATION PROPERTY BY INTRODUCING MODIFYING ADDITIVES OF NATURAL ORIGIN

The possibility of the introduction of the flask in asphalt concrete as a mineral supplement. The results of studies of the flask’s effect on the bitumen adhesion to the mineral material in the asphalt mixture. The results allow to receive the asphalt mix with a higher index of bitumen adhesion to the mineral material. Shows the production of asphalt concrete technology with the introduction of the flask as a mineral supplement.

Sensor Node Identifier Resolution of IP-Based and Non-IP-Based WSN

Traditional wireless sensor network(WSN) technology has localization limitations due to the data-centric characteristic.Therefore, it’s very important to introduce identifier resolution technology and the kernel of using identifier resolution technology is to trace sensor node and get the application information and real time data in WSN.This paper designed a sensor node identifier resolution method of IP-based and non-IP-based WSN,and it gets the sensor node production property information through Internet-based sensor node identifier resolution,while the real-time data and application property of sensor node in practical environment are obtained by WSN-internal sensor node identifier resolution.The process of sensor node identifier resolution is validated to be effective with being applied in the smart home system.

Properties of Epoxy Modified Mortar Used in Caulking

By this method of adding fly ash of equal amount in the mortar, making analysis including the decreasing water change、7d and 28d compressive strength as well as flexural strength. Results show that exists the optimum proportion of fly ash cement mortar, that is C：F：S：W=220：55：1410：275.On the basis of mixing only 20% fly ash and epoxy resin-polymer, doing analysis about the decreasing water change、7d compressive strength and flexural strength、application property. At the same time, this paper fits the regression equation which using the 7d compressive strength and flexural strength、decreasing water rate as the dependent variables, polymer cement ratio as the independent variable. More important is that the credibility of regression equation is much high.

Application Property and Structural Characteristics of Bark Lignosulfonate Superplasticiser

The application property and structural characteristics of bark lignosulfonate (LS) was studied. Results showed that bark LS had perfect application property in concrete. The fluidity of cement paste was 214mm, which was 87.0% of commercial superplasticiser of naphthalene sulfonate; the loss on fluidity of cement paste of bark LS was very small, which was much better than that of naphthalene sulfonate. The loss on fluidity of cement paste of bark LS after 60 min was only 5.6%, but that of naphthalene sulfonate was 30.6%. Bark LS had low foaming capacity and high foam stability. Surface tension of 1% bark LS solution was 48.1 mN/m. Structural characteristics of bark LS was also studied. It showed that the reason that bark LS had good application property was that it had high content of hydrophilic sulfonic group, carboxyl group and phenolic hydroxyl group, and uniform molecular weight distribution.
