Characterization of Ultrafast Decomposition Dynamics in Nitrate Esters
Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT Ignition of energetic materials initiates chemical reactions on atomic length scales within femtoseconds, making these reactions difficult to investigate experimentally. The technique of femtosecond time‐resolved mass spectrometry (FTRMS) can capture molecular rearrangement and bond‐breaking events in isolated molecules with sub‐50 femtosecond

Electrodynamic actuators for rocket engine valves [PDF]
, 1972 Actuators, employed in acoustic loudspeakers, operate liquid rocket engine valves by replacing light paper cones with flexible metal diaphragms. Comparative analysis indicates better response time than solenoid actuators, and improved service life and ...

steel research international, EarlyView.Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater
Groundwater Monitoring &Remediation, EarlyView.Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.

Viability of an Electrically Driven Pump-Fed Hybrid Rocket for Small Launcher Upper Stages
Aerospace, 2019 An electrically driven pump-fed cycle for a hybrid rocket engine is proposed and compared to a simpler gas-pressurized feed system. A liquid-oxygen/paraffin-based fuel hybrid rocket engine which powers the third stage of a Vega-like launcher is ...

Journal of Management Studies, EarlyView.Abstract This study investigates how small and medium‐sized enterprises (SMEs) respond to deglobalization and economic nationalism, using historical evidence from fascist Italy, a period of autarky and restricted international trade. While prior research has focused primarily on larger firms, especially multinational enterprises (MNEs), the strategic ...
