Azobenzene‐Oxindole Photochromic Dyads

Angewandte Chemie, EarlyView.
A novel photochromic azobenzene‐oxindole dyad is reported. The combination of the two switches promotes drastic molecular geometry changes and allows for precise NMR quantification. This enables the study of the photokinetic behavior under different irradiation conditions and the discovery of a unique photokinetic relationship between the two ...

A Quantum algorithm for linear PDEs arising in Finance [PDF]

arXiv, 2019
We propose a hybrid quantum-classical algorithm, originated from quantum chemistry, to price European and Asian options in the Black-Scholes model. Our approach is based on the equivalence between the pricing partial differential equation and the Schrodinger equation in imaginary time.

A Programmable Nanoparticle Conversion Pathway to Monodisperse Polyelemental High Entropy Alloy, Intermetallic, and Multiphase Nanoparticles

Angewandte Chemie, EarlyView.
Polyelemental nanoparticles, composed of four or more elements, encompass high‐entropy alloys, high‐entropy intermetallics, and multiphase structures such as Janus and core‐shell architectures. These nanoparticles were obtained through the thermal transformation of colloidally synthesized core‐shell nanoparticles. Systematic variations in stoichiometry

Synthesis of heat‐integrated thermally coupled nonsharp distillation using self‐adaptive spherical search

AIChE Journal, EarlyView.
Abstract Although thermally coupled distillation (TCD) exhibits strong energy efficiency, the possibility of utility cost savings remains debatable. TCD designs that do not consider vapor transport can underestimate costs, making section rearrangement crucial to find more operable configurations.

Implications of state policy context for the well‐being of immigrant families with young children

American Journal of Community Psychology, EarlyView.
Abstract There is notable variation in state‐level social policy exclusions for immigrant parents and their children. Little research has investigated how these exclusions impair the well‐being of immigrant families. This study examined how state‐level social policy exclusions for immigrants are associated with the well‐being of immigrant parents and ...
