Thermomechanical investigation on the effect of nitroguanidine on the thermal expansion coefficient and glass transition temperature of double-base gun propellant

open access: yesJournal of Materials Research and Technology, 2019
Thermal expansion coefficient (CTE) is a critical parameter of gun propellant because of its major role in fabrication, storage and combustion performance of the propellant.

Reversible Phase Transitions of Anionic and Cationic Surfactant Mixtures Drive Shape Morphing Droplets

open access: yesAdvanced Materials, EarlyView.
A light‐controlled, reversible phase transition of ionic surfactant assemblies, coupled with dynamic partitioning between bulk phases and interfaces, induces rapid, and order‐of‐magnitude changes in oil–water interfacial tension. Surpassing the capabilities of conventional stimuli‐responsive surfactants, this transient, collaborative mechanism enables ...

Study on the analysis method on ballistic performance of deterred propellant with large web size in large caliber artillery

open access: yesDefence Technology, 2018
As for the characteristics of combustibility of deterrent propellant with large web size which is used in large-caliber gun and interior ballistic performance, the combustion characteristics of deterrent propellant are obtained by using closed-bomb ...

Anchoring Unimolecular Metal Chloride as a Sterically Active Site for Conformal Zinc Electrodeposition

open access: yesAdvanced Materials, EarlyView.
An octahedrally coordinated MnCl2N4 structure anchored on hard carbon tailors the electronic environment of single atoms to lower zinc nucleation barriers. Chloride‐assisted Zn adsorption with Jahn‐Teller distortion and residual Zn enables reduced overpotential.

Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

open access: yesAdvanced Materials, EarlyView.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic
