Quaternary cocrystals: combinatorial synthetic strategies based on long-range synthon Aufbau modules (LSAM)

IUCrJ, 2016
A synthetic strategy is outlined whereby a binary cocrystal may be developed in turn into a ternary and finally into a quaternary cocrystal. The strategy hinges on the concept of the long-range synthon Aufbau module (LSAM) which is a large supramolecular

Nature and origin of unusual properties in chemically exfoliated 2D MoS2

APL Materials, 2020
MoS2 in its two-dimensional (2D) form is known to exhibit many fundamentally interesting and technologically important properties. One of the most popular routes to form an extensive amount of such 2D samples is the chemical exfoliation route.

Tunable topology and berry curvature dipole in transition metal dichalcogenide Janus monolayers

Materials Research Express, 2021
Janus transition metal dichalcogenides, with intrinsic mirror asymmetry, exhibit a wide array of interesting properties. In this work, we study Janus monolayers derived from WTe _2 using first-principles and tight-binding calculations.

Disordered light-harvesting aggregates can host functional vibronic couplings at room temperature

Nature Communications
Photosynthesis relies on a network of chlorophyll-like molecules which together lead to efficient long-range energy transfer. Evidence at cryogenic temperatures suggests that mechanistic details of energy/charge transfer must invoke coupled vibrational ...
