Challenges in Elucidating the Free Energy Scheme of the Laccase Catalyzed Reduction of Oxygen
ChemCatChem, Volume 15, Issue 1, January 9, 2023., 2023 Bioinorganic chemistry: High potential variants of the multicopper enzyme laccase have a remarkably low overpotential for the oxygen reduction reaction (ORR). Understanding the precise underlying principles are potentially of great value in light of the energy transition wherein the ORR plays a crucial role.

Methane Cluster Fragmentation by Fast Electron Impact
Atoms, 2023 We investigate the fragmentation of the CH4 cluster by fast electron impact at stagnation pressures from 0.5 bar to 16 bar. By measuring the time of flight spectrum (TOF), two types of ions, including (CH4)n−1CH5+ and (CH4)n−2(C2Hm)+, are observed.

Performance analysis of a rotating detonation combustor based on stagnation pressure measurements [PDF]
Combustion and Flame, 2020 Abstract This study explores the effect of differing inlet and outlet boundary conditions on the operation and performance of a rotating detonation combustor (RDC) over an annulus mass flux range of 50 to 210 kg s − 1 m − 2 and equivalence ratios of 0.7, 1.0, and 1.3.

Cavitation Erosion Resistance of Additively Manufactured Materials
Chemical Engineering &Technology, Volume 46, Issue 1, Page 37-44, January 2023., 2023 Cavitation‐induced wear can be found in many fluid power components. The effects of additively manufactured materials on the resistance to cavitation erosion were investigated, compared to conventional manufacturing. Mass loss and the surface structure were measured as the main indicators of cavitation erosion.

Jets and the shaping of the giant bipolar envelope of the planetary nebula KjPn 8 [PDF]
, 1998 A hydrodynamic model involving cooling gas in the stagnation region of a collimated outflow is proposed for the formation of the giant parsec-scale bipolar envelope that surrounds the planetary nebula KjPn 8. Analytical calculations and numerical simulations are presented to evaluate the model.

Influence of High Pressure Drop Rates on Fatigue Crack Growth
Chemical Engineering &Technology, Volume 46, Issue 1, Page 45-52, January 2023., 2023 Hydraulic components are subjected to varying loads, limiting their lifetime. Accelerating fatigue studies through high‐frequency pulsation would decrease costs and time to market. However, the fluid‐structure interaction causes a time‐dependent fatigue load.

Flow structure beneath periodic waves with constant vorticity under normal electric fields [PDF]
, 2022 Waves with constant vorticity and electrohydrodynamics flows are two topics in fluid dynamics that have attracted much attention from scientists for both the mathematical challenge and their industrial applications. The coupling of electric fields and vorticity is of significant research interest.
