Hydrogel based controlled release formulations: Designing considerations‚ characterization techniques and applications. Abstract Hydrogels have evolved over the last decade as materials of choice in varied biomedical applications. This is associated with the inherent biocompatible nature of the hydrogels. The modulation of the properties of the hydrogels is easily possible due to the availability of polymers of varied chemistry and physical properties. This review discusses the pharmaceutical

Natural dyes are dyes or colorants derived from plants‚ invertebrates‚a or minerals. The majority of natural dyes are vegetable dyes from plant sources – roots‚ berries‚ bark‚ leaves‚ and wood — and other organic sources such as fungi and lichens. Archaeologists have found evidence of textile dyeing dating back to the Neolithic period. In China‚ dyeing with plants‚ barks and insects has been traced back more than 5‚000 years.[1] The essential process of dyeing changed little over time. Typically

CHAPTER I INTRODUCTION Background of the Study The term “air pollution” is used to describe substance that are artificially introduced into the air. Air pollutions stems from gases and airborne particles which‚ in excess‚ are harmful to human health‚ buildings and ecosystems. This pollution also affects the environment. Like there are many causes for this pollution‚ there are various side effects of the same on the environment and living beings in it. Some of the biggest effects on the environment
