RIO DE JANEIRO, BRAZIL - Brazilian ethanol produced from sugarcane is even more sustainable than previously thought, according to a study coordinated by the National Center for Energy and Materials Research.
CNPEM researchers, in collaboration with the Agronomy Institute of Campinas (IAC), have developed a new model for calculating the so-called carbon equivalent that considers the specific characteristics of the soil of sugarcane plantations in the country.
Today, the standard proposed by the Intergovernmental Panel on Climate Change (IPCC) is used to calculate carbon equivalent emissions. This model is based on data collected in temperate climate soils, says CNPEM researcher . . .

A collaborative group from Tohoku University and Johns Hopkins University have provided valuable insights into the glass transition.
When a liquid is cooled rapidly, it gains viscosity and eventually becomes a rigid solid glass. The point at which it does so is known as the glass transition.
But the exact physics behind the glass transition, and the nature of glass in general, still pose many questions for scientists.
Metallic Glasses (MGs) are highly sought after since they combine the flexibility of plastic with the strength of steel. They are amorphous materials with a disordered atomic structure and exhibit unique and divergent thermodynamic and dynamic characteristics, especially when approaching the glass-transition temperature.
