This paper presents a hybrid analytical framework for modeling the two-dimensional motion of a rocket with variable mass, incorporating mass loss due to fuel expenditure. While classical approaches like Tsiolkovsky’s rocket equation focus on one-dimensional motion, real-world launch vehicles experience complex 2D trajectories influenced by thrust

The Influence of Infill Density on the Impact Behavior of 3D‐Printed PLA Parts
Macromolecular Symposia, EarlyView.ABSTRACT The study focuses on the experimental determination of the impact behavior of PLA components manufactured through additive manufacturing, where the infill density of each tested specimen is varied. The evaluation of the impact energy absorbed by each configuration provides relevant insights into the influence of internal structure on ...

Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols
Polymer International, EarlyView.We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.

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.

PLANTS, PEOPLE, PLANET, EarlyView.Anthropogenic facilitation of wild plants based on aesthetic preferences for particular traits can change the biogeography and ecology of natural communities. We use a mixed‐methods socioecological approach to characterize the ways in which humans interact with a common, widely distributed plant and a generalist viral symbiont that induces an ...
