On the Mechanism of Soft Self‐assembly from Melt: The ubiquitous Heat Capacity Hump and Spontaneous Melt Chirality

open access: yesAngewandte Chemie International Edition, Accepted Article.
We investigate two unusual phenomena in self‐assembly of anisotropic molecules from isotropic (Iso) melt: a heat‐capacity (Cp) maximum, and spontaneous formation of the recently discovered chiral liquid (Iso*). Based on experiments on new non‐chiral monomers, dimers and polymers, we construct a statistical theory that shows why many complex ...

Reactivity of Pnictaalumenes towards 1,3‐Dipole Molecules

open access: yesAngewandte Chemie International Edition, Accepted Article.
Alkynes undergo 1,3‐dipolar cyclisation reactions with organic azides giving 1,2,3‐triazoles. Pnictaalumenes RPn=AlRˈ are the isoelectronic congeners of alkynes, hence a similar reactivity towards 1,3‐dipole molecules is expected. Herein, we report the reactions of DippTerPn=AlCp* (DippTer = 2,6‑(2,6‐iPr2C6H3)‐C6H3, Cp* = [Me5C5]−, Pn = P, As) towards ...

A Review on Factors Affecting Large Truck–Involved Crashes

open access: yesIranian Journal of Health, Safety and Environment
Crashes involving large trucks have a significant association with increasing fatalities or serious injuries. Identifying the factors affecting large trucks crashes can be helpful in reducing the number of crashes and corresponded consequences.

A Generative Deep Learning Approach for Crash Severity Modeling with Imbalanced Data [PDF]

open access: yesarXiv
Crash data is often greatly imbalanced, with the majority of crashes being non-fatal crashes, and only a small number being fatal crashes due to their rarity. Such data imbalance issue poses a challenge for crash severity modeling since it struggles to fit and interpret fatal crash outcomes with very limited samples. Usually, such data imbalance issues
