Nanostructured rigid polyurethane foams with improved specific thermo-mechanical properties using Bacterial Nanocellulose as a Hard Segment [PDF]
arXiv, 2020 Bacterial nanocellulose (BNC) was used to synthesize rigid polyurethane foams (RPUFs) based on its reaction with the isocyanate precursor (ISO route) and also by using the conventional procedure (POL route). The results indicated that at only 0.1 wt. % of BNC, drastic improvements of specific elastic compressive modulus (+244.2 %) and strength (+77.5 %)

Carbamoylating activity associated with the activation of the antitumor agent laromustine inhibits angiogenesis by inducing ASK1-dependent endothelial cell death. [PDF]
PLoS ONE, 2014 The anticancer agent 1,2-bis(methylsulfonyl)-1-(2-chloroethyl)-2-[(methylamino)carbonyl]hydrazine (laromustine), upon decomposition in situ, yields methyl isocyanate and the chloroethylating species 1,2-bis(methylsulfonyl)-1-(2-chloroethyl)hydrazine ...

Advanced Materials Interfaces, EarlyView.A stable bio‐based nanocomposite coating for urinary catheters is developed using a simple, environmentally‐friendly sonochemical process. The coating, integrating antimicrobial, antibiofilm, and antioxidant properties, effectively tackled multiple early‐stage pathogenic factors associated with catheter‐associated urinary tract infections.

Interstellar Detection of Methyl Isocyanate CH$_3$NCO in Sgr B2(N): A Link from Molecular Clouds to Comets [PDF]
, 2015 A new interstellar molecule, CH$_3$NCO (methyl isocyanate), has been detected using the 12 m telescope of the Arizona Radio Observatory (ARO). CH$_3$NCO was identified in spectra covering 48 GHz (68-116 GHz) in the 3 mm segment of a broadband survey of Sgr B2(N).
