In common perception, carbon dioxide is just a greenhouse gas, one of the major environmental problems of mankind. For Warsaw chemists CO2 became, however, something else: a key element of reactions allowing for creation of nanomaterials with unprecedented properties.
Resistance of tumor cells toward multiple cytostatic drugs is a serious problem in cancer treatment. Researchers have now introduced a new approach to gene therapy that could counter this problem: The gene that codes for resistance is 'silenced' through the use of an ingenious nanocomplex.
In the US, someone suffers a heart attack every 34 seconds -- their heart is starved of oxygen and suffers irreparable damage. Engineering new heart tissue in the laboratory that could eventually be implanted into patients could help, and scientists are reporting a promising approach tested with rat cells. They published their results on growing cardiac muscle using a scaffold containing carbon nanofibers
As part of his PhD, postdoctoral research fellow Dr Daniel Tune has designed a computer modelling system that shows which combination of carbon nanotubes absorb the most sunlight, therefore providing the most energy.
Researchers have discovered a novel solid state reaction which lets kesterite grains grow within a few seconds and at relatively low temperatures. For this reaction they exploit a transition from a metastable wurtzite compound in the form of nanorods to the more stable kesterite compound.
