A Fundamental Investigation on the High Intensity Combustion : 1st Report, On the Local Combustion Efficiency in an Upright Combustion Chamber

open access: yesTransactions of the Japan Society of Mechanical Engineers, 1967
The local combustion efficiency and the local heat release rate in an upright cylindrical combustion chamber having a diameter of 100 mm and a length of about 1000 mm, were experimentally determined from the contents of combustion products. The burnt gases sampled from ten positions in the combustion chamber were analyzed with gaschromatograph.

High‐Power Rapid Laser‐Induced Synthesis of Multi‐functional Cobalt Metal‐Organic Framework With an Unprecedented Synthesis Efficiency

open access: yesAdvanced Materials Technologies, EarlyView.
Laser‐assisted synthesis enables rapid (within 1 h) and high‐yield (≥90%) production of Co‐MOFs with mesoporous structures, tunable magnetic and optical properties, and efficient adsorption of N2, CH4, and CO2 for low‐energy gas separation. DFT calculations elucidate the electronic structure and adsorption behavior.
