The Legionella pneumophila chaperonin – an unusual multifunctional protein in unusual locations

open access: yesFrontiers in Cellular and Infection Microbiology, 2011
The L. pneumophila chaperonin, HtpB, was discovered as a highly immunogenic antigen, only a few years after the identification of L. pneumophila as the causative agent of Legionnaires’ disease.

A Structural Integrity Perspective for the Assessment of Ageing in Composite Solid Propellants

open access: yesPropellants, Explosives, Pyrotechnics, Volume 50, Issue 10, Page 152-158, October 2025.
ABSTRACT Composite solid propellants (CSPs) are critical materials in the defence and aerospace industries, known for their complex mechanical behaviour and susceptibility to ageing. This study explores the application of Principal Component Analysis (PCA) to discriminate the ageing degradation of CSPs based on structural integrity parameters.

PERUBAHAN KARAKTERISTIK PEMBENTUKAN POLIURETAN BERBASIS HTPB DAN TDI BERDASARKAN KOMPOSISI REAKSI (CHANGES IN THE FORMATION CHARACTERISTICS OF POLYURETHANE BASED ON HTPB AND TDI REACTION COMPOSITION)

open access: yes, 2016
Polyurethane formation occurs through crosslinking of a reaction between the hydroxyl group (OH) of HTPB and isocyanate (NCO) of TDI. Polymer network formation reaction will be formed from the linear bond and a combination of crosslinking.

Amine‐AlH3 Adducts as Energetic Materials for a New Generation of Solid Fuels

open access: yesChemistry – A European Journal, Volume 31, Issue 40, July 17, 2025.
New amine‐AlH₃ adducts offer a more environmentally friendly, high‐energy alternative to conventional rocket propellants, and exhibit ultra‐fast ignition. They can be synthesized by mechanochemical method under hydrogen pressure starting from aluminum metal directly or by wet chemical processes with AlH3.

IDENTIFICATION OF AMINO ACIDS INVOLVED IN THE MOONLIGHTING FUNCTIONS OF HTPB, THE LEGIONELLA PNEUMOPHILA CHAPERONIN

open access: yes, 2015
Chaperonin 60s (Cpn60s) and their cognate co-chaperonin 10s (Cpn10s) are highly conserved housekeeping proteins that provide favorable conditions for the correct folding of other proteins.
