Orbital stability in a classical pilot-wave system by Liu, Nicholas Z.

“…In the limit of vanishing particle inertia, infinite path memory and a linear spring force, we demonstrate the intriguing possibility of infinitely many sharply quantised orbital states, where the allowed orbital radii exist in vanishingly thin intervals, and are stabilised by the combined influence of the time-averaged wave field and spring force. …”

Fast pyrolysis of cellulose, hemicellulose, and lignin : effect of operating temperature on bio-oil yield and composition and insights into the intrinsic pyrolysis chemistry by Ansari, Khursheed Badruddin, Arora, Jyotsna Sudhir, Chew, Jia Wei, Dauenhauer, Paul J., Mushrif, Samir H.

“…However, the yield and composition of bio-oil are governed by numerous pyrolysis reactions which are difficult to understand because of the multiphase decomposition phenomena with convoluted chemistry and transport effects at millisecond time scales. In this work, thin-film pyrolysis experiments of biopolymers present in the biomass (i.e., cellulose (â¼50 μm), hemicellulose (using xylan as a model biopolymer, â¼12 μm), and lignin (â¼10 μm)) were performed over 200-550 °C, to investigate underlying thermal decomposition reactions, based on the product distribution obtained under reaction-controlled operating conditions. …”
