Evaluation of Iron‐Phosphate Glass–Ceramic Waste Form for Electrorefiner Salt Waste Simulant Dechlorinated With Phosphoric Acid

International Journal of Ceramic Engineering &Science, Volume 8, Issue 3, May 2026.
This work investigates the formation of high‐alkali‐iron‐phosphate glass–ceramic waste forms made from the dechlorinated product of a phosphoric acid‐based process. The salt simulant is mixed with H3PO4 to form a slurry, heated, and then the dechlorinated product is vitrified with glass formers to obtain the final waste form. ABSTRACT The importance of

Highly active iridium(I) complexes for the selective hydrogenation of carbon-carbon multiple bonds [PDF]

, 2011
New iridium(I) complexes, bearing a bulky NHC/phosphine ligand combination, have been established as extremely efficient hydrogenation catalysts that can be used at low catalyst loadings, and are compatible with functional groups which are often ...

Intercepting 1,2‐Diamantene: A Doubly Bridgehead Anti‐Bredt Alkene

ChemistryEurope, Volume 4, Issue 5, May 2026.
Doubly bridgehead olefin 1,2‐diamantene, which resembles an elusive trans‐cyclohexene moiety was generated from 1,2‐diiododiamantane. The diamantane scaffold thermodynamically and kinetically stabilizes this highly twisted olefin due to efficient hyperconjugation with the C–C bonds of the cage, while dimerization is hampered due to steric crowding ...

Radiation damage in sub‐Ångström resolution macromolecular crystallography: a low‐dose study

Acta Crystallographica Section D, Volume 82, Issue 5, Page 484-491, May 2026.
This first systematic radiation‐damage study at 0.55 Å resolution reveals extensive small conformational changes in response to dose. The findings demonstrate the benefits of using large crystals fully bathed in a large `top‐hat' beam with a uniform fluence profile, together with low‐dose data‐collection protocols, for sub‐Ångström structure ...

The Arsenal of Aromatic Degrading Bacteria: How They Sense, Chase, Adapt and Destroy Environmental Pollutants

Microbial Biotechnology, Volume 19, Issue 5, May 2026.
In the environment, bacteria sense aromatic pollutants, migrate toward them, adapt to toxicity, and deploy specialized uptake and catabolic systems. Genomic plasticity, metabolic versatility and division of labor within populations together aid in the degradation of persistent aromatics, highlights that biodegradation is driven by various eco ...

Transfer Hydrogenation of Organic Azides to Amines by Ammonia Borane Complex Under Mild Conditions Catalyzed by Reusable Au Nanoparticles

European Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
Organic azides are readily reduced to amines under mild conditions by ammonia borane complex, catalyzed by a low loading level of reusable Au nanoparticles supported on TiO2. We present the first protocol for the chemoselective reduction of organic azides to amines by ammonia borane complex. In the presence of a low catalytic amount of Au nanoparticles
