Synthetic single-wall carbon nanotubes (SWCNTs) contain various chiralities, which can be sorted by DNA. However, finding DNA sequences for this purpose mainly relies on trial-and-error methods. Predicting the right DNA sequences to sort SWCNTs remains a substantial challenge.

Traditional colitis treatment strategies have issues such as side effects and poor lesion targeting. In this study, a milled black rice particle-stabilized Pickering emulsion (BR-5-DMN) has been developed as a delivery vehicle for 5-demethylnobiletin (5-DMN) to treat colitis. The alleviating effects of three 5-DMN delivery systems: BR-5-DMN, Tween 80 emulsion for upper gastrointestinal delivery, and soybean oil with most 5-DMN entering the colon were compared.

Unveiling the nonlinear interactions between terahertz (THz) electromagnetic waves and free carriers in two-dimensional materials is crucial for the development of high-field and high-frequency electronic devices. Herein, we investigate THz nonlinear transport dynamics in a monolayer graphene/MoS heterostructure using time-resolved THz spectroscopy with intense THz pulses as the probe. Following ultrafast photoexcitation, the interfacial charge transfer establishes a nonequilibrium carrier redistribution, leaving free holes in the graphene and trapping electrons in the MoS.

The embellishing of the macrocycle core with sulfur substituents of varied sterical requirements changes the structural dynamics of chiral, triangular polyimines. Despite their formal high symmetry, these compounds adopt diverse conformations, in which the macrocycle core represents a non-changeable unit. DFT calculations reveal that the mutual arrangement of sulfur-containing substituents is controlled mainly by sterical interactions.

Interaction of a novel dihydroxy dibenzoazacrown (HDTC) with various surfactants of different charges, for example, anionic (sodium dodecylsulfate, SDS), cationic (dodecyl trimethylammonium bromide, DTAB), cationic gemini (butanediyl-1,4-bis(dimethylcetylammonium bromide), 16-4-16), ionic liquid (1-hexadecyl-3-methylimidazolium chloride, CMImCl), and nonionic (polyoxyethylene sorbitan monostearate, Tween-60), has been investigated at a widespread range of surfactant concentrations (including premicellar, micellar, and postmicellar regime) in 15% (v/v) EtOH medium at room temperature. Several experimental techniques, viz., tensiometry, UV-vis spectroscopy, and steady-state fluorimetry, are implemented to explicate these interactions.
