Measurements of Radical Reactivity with an Imine, (CF₃)₂CNH: Rate Constants for Chlorine Atoms and Hydroxyl Radicals and the Global Warming Potential [PDF]

Molecules
The rate constant kOH for the reaction of 1,1,1,3,3,3-hexafluoroprop-2-imine with OH radicals was measured relative to two reference compounds, CH3F and CH3CHF2, to be kOH = (4.2 ± 1.1) × 10−14 cm3 molecule−1 s−1 at 295 K.

Assessing the Accessibility of Cycling Infrastructure for Wheelchair Users: Insights from an On-Road Experiment and Online Questionnaire Study

Vehicles, 2023
In this paper, we pay significant attention to the most vulnerable road users (i.e., people with disabilities) when interacting with cyclists. The special needs of these groups are studied by distributing an online questionnaire about their perception ...

On Coordinating Collaborative Objects [PDF]

Electronic Proceedings in Theoretical Computer Science, 2010
A collaborative object represents a data type (such as a text document) designed to be shared by a group of dispersed users. The Operational Transformation (OT) is a coordination approach used for supporting optimistic replication for these objects.

An Overview: Using Different Approaches to Synthesis New Schiff Bases Materials [PDF]

مجلة جامعة الانبار للعلوم الصرفة, 2021
Schiff base compounds are called relative to the scientist who first prepared them (Hugo Schiff). They are synthesized by the condensation reaction of the carbonyl group –C=O– of the aldehyde or ketone compound with a primary amine.

Dynamic Hydrogels Based on Double Imine Connections and Application for Delivery of Fluorouracil

Frontiers in Chemistry, 2020
Dynamic hydrogels have been prepared by cross-linking of O-carboxymethyl chitosan (O-CMCS) with reversibly connected imino-PEGylated dynamers. The double imine chitosan/dynamer and dynamer bonds and were used to provide tighter structures and adaptive ...
