Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Comminution of energetic materials in viscous binder components with high solid loadings

, 2018
S.120.1-120.10Wet comminution enables the production of very fine energetic particles direct in binder components. Besides the processing of energetic materials, the general high viscosities of binder materials are challenging.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Preparation of ammonium nitrate-based solid composite propellants supplemented with polyurethane/nitrocellulose blends binder and their thermal decomposition behavior

Defence Technology, 2022
To improve the performance of solid composite propellants (SCPs) supplemented with ammonium nitrate (AN) as an oxidizer, the incorporation of energetic ingredients such as explosives, energetic binders or catalysts is a common effective approach.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Advancing nitrocellulose thermal stability through the incorporation of ion-exchanged ZSM-5 zeolite for enhanced performance

FirePhysChem
In this study, cellulose nitrate (NC), a highly energetic polymer, was supplemented with two distinct classes of stabilizing agents: the usual diphenylamine (DPA) and zeolite molecular sieves (ZSM-5) that were ion-exchanged with transition metal ions ...

A promising high-energy-density material

Nature Communications, 2017
High energy density materials are of interest, but density is the limiting factor for many organic compounds. Here the authors show the formation of a high density energetic compound from a two-step reaction between commercially available compounds that ...

Effect of micro- and nano-CuO on the thermal decomposition kinetics of high-performance aluminized composite solid propellants containing complex metal hydrides

FirePhysChem, 2022
In the present work, an attempt has been made to unveil the effect of micro- and nano-particles of copper oxide (µCuO and nCuO) on the thermal decomposition of composite solid propellants (CSPs) based on ammonium perchlorate, hydroxyl terminated ...
