TL;DR: A library of organic triplet sensitizers based on a single chromophore of boron-dipyrromethene (BODIPY) is proposed, paving the way for the design and applications in photovoltaics and upconversions, etc.
Abstract: Triplet-triplet annihilation (TTA) based upconversions are attractive as a result of their readily tunable excitation/emission wavelength, low excitation power density, and high upconversion quantum yield. For TTA upconversion, triplet sensitizers and acceptors are combined to harvest the irradiation energy and to acquire emission at higher energy through triplet-triplet energy transfer (TTET) and TTA processes. Currently the triplet sensitizers are limited to the phosphorescent transition metal complexes, for which the tuning of UV-vis absorption and T(1) excited state energy level is difficult. Herein for the first time we proposed a library of organic triplet sensitizers based on a single chromophore of boron-dipyrromethene (BODIPY). The organic sensitizers show intense UV-vis absorptions at 510-629 nm (e up to 180,000 M(-1) cm(-1)). Long-lived triplet excited state (τ(T) up to 66.3 μs) is populated upon excitation of the sensitizers, proved by nanosecond time-resolved transient difference absorption spectra and DFT calculations. With perylene or 1-chloro-9,10-bis(phenylethynyl)anthracene (1CBPEA) as the triplet acceptors, significant upconversion (Φ(UC) up to 6.1%) was observed for solution samples and polymer films, and the anti-Stokes shift was up to 0.56 eV. Our results pave the way for the design of organic triplet sensitizers and their applications in photovoltaics and upconversions, etc.

TL;DR: A near-infrared (NIR) light-triggered molecular superoxide radical (O2-•) generator (ENBS-B) is developed to surmount this intractable issue and extend the options of excellent agents for clinical cancer therapy.
Abstract: Hypoxia, a quite universal feature in most solid tumors, has been considered as the “Achilles’ heel” of traditional photodynamic therapy (PDT) and substantially impairs the overall therapeutic efficacy. Herein, we develop a near-infrared (NIR) light-triggered molecular superoxide radical (O2–•) generator (ENBS-B) to surmount this intractable issue, also reveal its detailed O2–• action mechanism underlying the antihypoxia effects, and confirm its application for in vivo targeted hypoxic solid tumor ablation. Photomediated radical generation mechanism study shows that, even under severe hypoxic environment (2% O2), ENBS-B can generate considerable O2–• through type I photoreactions, and partial O2–• is transformed to high toxic OH· through SOD-mediated cascade reactions. These radicals synergistically damage the intracellular lysosomes, which subsequently trigger cancer cell apoptosis, presenting a robust hypoxic PDT potency. In vitro coculture model shows that, benefiting from biotin ligand, ENBS-B achieve...

TL;DR: In this article, a review of spray cooling is presented, focusing on the relatively high-flux, low-temperature mechanisms and predictive tools associated with the single-phase liquid cooling and nucleate boiling regimes, as well as critical heat flux (CHF).

TL;DR: It is argued that six factors, including economics, resource, strategy, risk, management and quality, should be considered for outsourcing decisions, and proposes the use of analytic hierarchy process (AHP) and preference ranking organization method for enrichment evaluations (PROMETHEE) as aids in making IS outsourcing decisions.
