Biochar physicochemical properties: pyrolysis temperature and feedstock kind effects
Reviews in Environmental Science and Bio\/technology, 2020 Biochar is a pyrogenous, organic material synthesized through pyrolysis of different biomass (plant or animal waste). The potential biochar applications include: (1) pollution remediation due to high CEC and specific surface area; (2) soil fertility ...

Temperature Independent Renormalization of Finite Temperature Field Theory [PDF]
, 2000 We analyse 4-dimensional massive $\vp^4$ theory at finite temperature T in the imaginary-time formalism. We present a rigorous proof that this quantum field theory is renormalizable, to all orders of the loop expansion. Our main point is to show that the
