Manipulating Dynamic Light-Driven Solid-Liquid Transition and Static Reversible Photochromism via Organic Cocrystal Strategy.

Developing of molecular crystalline materials with light-induced multiple dynamic deformation in space dimension and photochromism on time scales has attracted much attention for its potential applications in actuators, sensoring and information storage. Nevertheless, organic crystals capable of both photoinduced dynamic effects and static color change are rare, particularly for multi-component cocrystals system. In this study, we first report the construction of charge transfer co-crystals allows their light-induced solid-to-liquid transition and photochromic behaviors to be controlled by trans-stilbene (TSB) as an electron donor and 3,4,5,6-Tetrafluorophthalonitrile (TFP) as an electron acceptor.

Protein aggregates and particles in biopharmaceuticals can induce adverse immune responses in patients. Thus, suppression of the formation of protein aggregates and particles is important for the successful development of therapeutic proteins. Mechanical stresses, including agitation, are widely recognized as stress factors that generate protein aggregates and particles.

The oil film formed by the adhesion of crude oil to the resin-asphalt adsorption layer is difficult to peel off due to the strong oil-solid interaction, which severely limits further improvements in oil recovery. Although conventional compound oil displacement systems can effectively reduce oil-water interfacial tension, facilitate oil droplet deformation, and alleviate the Jamin effect, they are insufficient in controlling the wettability of oleophilic rock surfaces. In this paper, sodium nonylphenol polyoxyethylene ether sulfate (NPES) and sodium lauric acid ethanolamine sulfonate (HLDEA) were compounded to construct an efficient oil displacement system that simultaneously achieves wettability control of lipophilic surfaces and ultralow oil-water interfacial tension.

Purifying membrane proteins has been the limiting step for studying their structure and function. The challenges of the process include the low expression levels in heterologous systems and the requirement for their biochemical stabilization in solution. The human voltage-gated proton channel (hH1) is a good example of that: the published protocols to express and purify hH1 produce low protein quantities at high costs, which is an issue for systematically characterizing its structure and function.

White-light generation using small organic molecules has gained significant attention from researchers working on the interface of supramolecular chemistry and organic materials. Self-assembled multi-chromophoric materials utilizing a drug molecule and microenvironment-sensitive intramolecular charge transfer dye as an emitter offer the possibility of tunable emission. In this investigation, we focused on white light generation via the combination of a polarity-sensitive red-emitting styryl chromone (SC) and a blue-emitting anticancer and psychotherapeutic drug Norharmane (NHM) in a self-assembled micellar system.
