All that could change, says PhD student Jean-Pierre Amorij of the University of Groningen. In his thesis he describes a way of storing flu vaccine in powder form. It can then be stored for at least a year – more than enough time to build up national stocks.
Amorij will be awarded his PhD on 4 January 2008. During the past four years he has examined all kinds of methods for long-term storage of the flu vaccine. The answer lay in what is known as freeze drying – a protein molecule, such as a vaccine, is extremely quickly frozen between millions of sugar molecules. These molecules bunch together like miniscule balls around the vaccine, so that it can be stored stably in a dried form.Sugars

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...
Augsburg chemists present a new technology for compressing, storing and transporting highly volatile gases in porous frameworks/New prospects for gas-powered vehicles
Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
