Abstract:
Climate change and the depletion of fossil fuels have forced the developed world to look for clean energy alternatives. Solar cooking is developing in Asian and African countries blessed with ample sun, but is still at an early stage. A portable autoclave was developed in India using this technology. The Prince-40 Concentrator provided adequate capacity to autoclave culture media and treat biomedical waste in a small laboratory set-up, and could save electricity worth Rs. 15,000 (188.10 GBP)/year or LPG worth Rs. 37,500 (470.25 GBP)/year. This technology would be of immense use in health centres in rural areas with frequent power cuts or no power supply.

Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
Methods of Sterilization II: Chemical Methods
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
