Dihydroxyterephthalate-A Trojan Horse PET Counit for Facile Chemical Recycling.

Here, low-energy poly(ethylene terephthalate) (PET) chemical recycling in water: PET copolymers with diethyl 2,5-dihydroxyterephthalate (DHTE) undergo selective hydrolysis at DHTE sites, autocatalyzed by neighboring group participation, is demonstrated. Liberated oligomeric subchains further hydrolyze until only small molecules remain. Poly(ethylene terephthalate-stat-2,5-dihydroxyterephthalate) copolymers were synthesized via melt polycondensation and then hydrolyzed in 150-200 °C water with 0-1 wt% ZnCl , or alternatively in simulated sea water.

Adaptive body image can be contagious: An examination of college women facing situational body image threats.

The present research examined whether and which adaptive body image displays in peers can promote more adaptive body image in self. In two studies, female-identified undergraduates recalled a personally distressing body image event. In Study 1, participants (N = 158) then heard an alleged female-identified peer responding to her own distressing body image event with either self-compassion, self-esteem enhancement, or distraction.

AIRR Community Guide to Planning and Performing AIRR-Seq Experiments.

The development of high-throughput sequencing of adaptive immune receptor repertoires (AIRR-seq of IG and TR rearrangements) has provided a new frontier for in-depth analysis of the immune system. The last decade has witnessed an explosion in protocols, experimental methodologies, and computational tools. In this chapter, we discuss the major considerations in planning a successful AIRR-seq experiment together with basic strategies for controlling and evaluating the outcome of the experiment.
