Spin State‐Driven Modulation of Catalytic Activity of an Iron Spin‐Crossover Complex: Toward Switchable Catalysis

ChemCatChem, EarlyView.
The spin‐crossover (SCO) complex [Fe(NH2trz)3](NO3)2 catalyzes the acetalization reaction, with the high‐spin (HS) state producing up to 26% more acetal than the low‐spin (LS2) state. Acting as a Lewis acid, the SCO complex shows superior catalytic activity in the HS state due to better access to active sites rather than electronic effects under ...

Dynamic Covalent Polymer Networks of Silicone Elastomers via Organoborane Lewis‐Pairs

Chemistry – A European Journal, EarlyView.
DCPNs with reversible Lewis pair bonds are reported. Nitrogen‐borane adducts impart dynamic mechanical properties, such as self‐healing and recyclability, to polydimethylsiloxane elastomers. Abstract Dynamic covalent polymer networks (DCPNs) have been developed in recent years to offer distinctive mechanical properties and shape responsiveness in ...

A Case Study on Combining ASR and Visual Features for Generating Instructional Video Captions [PDF]

Published in The SIGNLL Conference on Computational Natural Language Learning (CoNLL) 2019, 2019
Instructional videos get high-traffic on video sharing platforms, and prior work suggests that providing time-stamped, subtask annotations (e.g., "heat the oil in the pan") improves user experiences. However, current automatic annotation methods based on visual features alone perform only slightly better than constant prediction. Taking cues from prior

Corn cob pyrolysis: A systematic literature review of methods and applications

The Canadian Journal of Chemical Engineering, EarlyView.
Mapping the research landscape of corn cob pyrolysis. Abstractas The agricultural sector is experiencing a surge in waste generation due to population growth, creating an urgent need to convert byproducts into value‐added products. Maize (Zea mays L.), a leading global crop, produces significant byproducts, such as corn cob, which are often undervalued.

Vibrational Infrared Lifetime of the Anesthetic nitrous oxide gas in solution [PDF]

Biophysical Review Letters, 1:309-316 (2006), 2007
The lifetime of the asymmetric fundamental stretching 2218 cm$^{-1}$ vibration of the anesthetic gas nitrous oxide (N$_2$O) dissolved in octanol and olive oil is reported. These solvents are model systems commonly used to assess anesthetic potency. Picosecond time-scale molecular dynamics simulations have suggested that protein dynamics or membrane ...
