How preprocessing methods affect the conversion efficiency of biomass energy production

A new study published in Bioresource Technology Reports examines the impact of biomass preprocessing on conversion efficiency. Researchers found that comminution and particle size play a significant role in determining energy expenditure, with miscanthus showing improved efficiency under certain conditions.

Quantum vacuum: Less than zero energy

A research team investigated the possibility of negative energy in quantum physics, finding that while energy can be less than zero under certain conditions, it must be paid back. The study placed tight bounds on negative energy and connected it to quintessential properties of quantum mechanics.
