Vaccine Transport

Stop Vaccines Waste – Take a Look at the Transport Chain!

India's vaccine industry ranks third in terms of volume globally in the world. Yet the question remains of why deaths are being reported even after immunization against a disease. One of the reasons for this is the improper transport of vaccines which cause the vaccine to lose its effectiveness. Use of phase change materials (PCMs) can help reduce vaccine wastage during transportation.

Solar Thermal Power Stations

Solar Thermal Power Stations Are a Prime Application for Canned Motor Pumps

Many industrial processes require heat energy to be moved from one place to another via a heat transfer fluid: typically water and steam at temperatures up to 200 °C, and heat transfer oils for the range 200–450 °C. Pumping fluids reliably at such high temperatures is a challenge that sealless canned motor pumps can meet. The new generation of solar thermal power stations provides a practical example.

The next level: Combined with the new ‘Sabre’-Reaction-Engine, a hybrid air-breathing rocket power plant that combines a turbo-compressor, pre-cooler and a closed cycle rocket engine, the future UAVs could be propelled to previously impossible hypersonic speeds or travel on the edge of space.

Chemputer: Downloading Chemicals

War and Peace: “Chemputer” Produces Tailor-Made Medicine – or Drones

It sounds like a scene from a science fiction movie: A newly developed method produces customized molecules in the reactor according to a building plan – to some extent the 3D printer for chemistry. Although the “Chemputer” was actually supposed to synthesise customized medicine, British defence and aerospace multinational BAE has secured the method. Now drones are expected to be developed in the chemical bath.
