The microemulgel can be used to achieve a combined effect of microemulsion and gel. It shows the dual control release effect of drugs and increasing stability. It has the primary objective ability to incorporate hydrophobic drugs. Various market products containing foreign agent, for example gel, cream, ointment they have several drawbacks, including poor absorption, poor permeability, allergic reaction, irritation, less spreading stickiness, and stability problem. This evaluation provides a summary of the best properties, excipient, preparation, and evaluation related to microemulgel. A recent study of recent development and future directions for microemulgel-based systems was conducted. The emulgel provides various beneficial aspects of its cosmetic and dermatology activity, thixotropic, greaseless, emollient, easily distributed, readily removable, non-staining and water-soluble, with a long half-life, biocompatible, and transparent and pleasant appearing. Therefore, emulgel is a better semi-solid preparation neither conventional system nowadays. It is utilized to administer of anti-inflammatory, anti-fungal, anti-acne, analgesic, anti-psoriasis drugs. The formulated emulgel is characterized of various parameters such as pH, viscosity, spreadability, etc. its need and merit will advance in the upcoming years.

Eu 3+ doped CaTiO 3 phosphors were prepared by the solid state reaction method at 1000 o C. Red long-afterglow (LAG) originated from the f-f transitions of Eu 3+ in the CaTiO 3 and lasted for several minutes. Defect trap depth values from 0.62 up to 1.21 eV were obtained from thermoluminescence (TL) data. These defects were created due to charge compensation. These traps were responsible for the afterglow emission at room temperature. The decay curves and TL glow curves showed that the density of the traps with suitable depth has been significantly changed with an increase in dopant concentration. The depth and density of the traps can affect the LAG performance. The 2 possible mechanism behind the LAG of Eu 3+ in CaTiO 3 was explained in detail on the basis of the trap distribution.

Convenient and reliable techniques for estimating the soil hydraulic properties are required for prediction of soil water flow. This paper presents the field and laboratory determination of soil moisture characteristics and their variation along the Hindon river in its upstream reach. A total of 38 soil samples were collected from 14 sites in Aurangabad, Kamalpur, Budhakhera, Gagalheri and Dudhil Bukhara comprising around 24 km reach, upstream of Hindon river. Extensive laboratory measurements were made for each soil sample collected. Porosity was obtained for each soil sample. Saturated hydraulic conductivity was measured through ICW Permeameter in the laboratory. Retention curve data was obtained through pressure plate apparatus. Unsaturated hydraulic conductivity function was indirectly derived through van Genuchten retention parameters by non-linear regression analysis.
