ABSTRACT TiN films deposited by physical vapor deposition (PVD) are widely used as protective films due to their high hardness and wear resistance. However, their application under high‐load conditions is limited by poor load‐bearing capacity and susceptibility to spalling on soft substrates.

Cryo‐EM structures of multiple‐peptide resistance factor (MprF) from Pseudomonas aeruginosa
Multiple peptide resistance factor (MprF) is a bacterial enzyme that carries out the aminoacylation of lipid head groups. CryoEM analysis of MprF from Pseudomonas aeruginosa reveals a dimeric enzyme, distinct from its homologues in Rhizobium. The soluble GNAT domain contains a dynamic amphipathic helix (TTH) that adopts different positions in detergent

Direct Ink Writing of Geopolymer Composites Reinforced With Polypropylene Fibers
ABSTRACT Polypropylene fiber (PPf) reinforced geopolymer inks were systematically optimized for extrusion‐based additive manufacturing through regulation of ink composition, rheological parameters, nozzle size, and fiber content. The effects of polyethylene glycol (PEG) content and H2O to K2O ratio on printability were investigated.
