Polarity‐engineered Sn‐Ti cluster photoresists for sub‐10‐nm high‐resolution lithography

open access: yesSmart Molecules, EarlyView.
Enhancing the polarity of clusters can optimize their patterning performance; inspired by this strategy, we designed polarity‐enhanced Sn‐Ti oxo clusters via ligand engineering. The optimal TS‐3 with exposure‐induced polarity switch achieves 8 nm patterning in lithography and achieves simultaneous improvement in resolution and patterning performance ...

Recent advances in polymeric chemically amplified positive resists: Materials and design strategies

open access: yesSmart Molecules, EarlyView.
This review summarizes recent advances in the molecular design of positive chemically amplified resists, focusing on photoacid generators and polymer architectures. Key strategies for enhancing sensitivity—including self‐amplification effects, copolymerization of sensitive monomers, controlled polymerization, and photosensitized chemically amplified ...

Reactivity of the oxime/oximato group in ruthenium(II) complexes

open access: yes, 2008
Oxime targeted reactions of the complexes trans-[(κ3-dapdOH)Ru(CO)(PPh3)2]PF6 (1) (dapdOH = diacetylpyridinedioxime) and trans-[(κ3-dapmOH)RuCl(PPh3)2]PF6 (2) (dapmOH = diacetylpyridinemonooxime) with SOCl2, NaBH4, or HCHO led into conversion of oxime to

Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

open access: yesThe Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Successful use of insect‐based (Hermetia illucens) diet in dogs with food‐responsive enteropathy

open access: yesJournal of Small Animal Practice, EarlyView.
Objective Diet is an integral component of the management of chronic enteropathy in dogs. The role of insect‐based diets in this disease remains unknown. The objective of this study was to evaluate the impact of an insect‐based (Hermetia illucens) diet in dogs with presumed food‐responsive enteropathy.

Efficacious Oxime for Organophosphorus Poisoning: A Minireview [PDF]

open access: yes, 2011
Oximes are well known as acetylcholinesterase reactivators and are used in organophosphorus poisoning to reactivate inhibited acetylcholinesterase. Therapeutically available oximes, namely, pralidoxime (2-PAM), obidoxime, trimedoxime and Hagedorn oxime ...

Formaldehyde oxime - nitrosomethane tautomerism

open access: yes, 2001
Formaldehyde oxime ⇌ nitrosomethane tautomerism, isomeric nitrone, and their common cations and anions are studied with Gaussian-2 theory using MP2(full)/6-31G* geometries and with density functional theory using B3LYP/6-311+G**.
