Mechanism of methanol and formaldehyde emissions from methanol-fueled engines
Published 2025-04-01“…The mechanism of methanol and formaldehyde was investigated respectively in a methanol premixed combustion test bench (PCTB) and a 304 stainless-steel flow reactor (SFR). The results of PCTB indicate that methanol cannot escape from the flame surface to form unburned methanol emissions. …”

Fibre-reinforced concrete as an aspect of green construction technology
Published 2024-01-01“…The safety factor against failure of fibre-reinforced beams on the shear strength for mixtures with different amounts of fibres increased approximately two times with the growth of content steel fibre from 0,25 to 1,50 %. Concrete with recycled coarse aggregates and fibre reinforcement shows similar strength and ductility properties as concrete with natural aggregates. …”
