PLANTS, PEOPLE, PLANET, EarlyView.Plant biostimulants are substances that are obtained from a variety of sources and are applied in minute quantities to enhance plant growth and vigor. In this review we detail how the use of plant biostimulants may contribute to efforts to achieving a number of the UN Sustainable Development Goals.

Modal Analysis of Solid Rocket Motor
DEStech Transactions on Materials Science and Engineering, 2017 How to avoid the natural frequency closing to the environment disturbance frequency is a very complicated problem in the solid rocket motor engine .Once the resonance phenomenon happened, Solid rocket motors will be subjected to a larger dynamic stress environment, resulting in engine damage.

Propellants, Explosives, Pyrotechnics, EarlyView.Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...
