In 1957‚ PHB was rediscovered in Britain and USA‚ and was further developed and researched during the 1960s. The mass production of PHB began after the 1990s because of the growing need for a environmentally friendly plastic alternative. Properties of PHB... The biodegradability of PHB gives it extraordinary appeal as a potential replacement for the widely used polymers derived from petrochemicals. These petrochemical products‚ such as polypropylene and polyethylene‚ are often used for packaging

Department of Chemistry [Colligative Properties & Osmotic Pressure] Purpose : The experiment this week had two different purposes. The first is to teach us about freezing points. This lab was designed to show us the freezing point of a pure solvent‚ in comparison to a solvent in a solution with a non-volatile solute. The second goal of the experiment is to teach students about osmosis. In the experiment‚ we got to observe osmosis as well as understand dialysis
