Enhancing photoluminescence quantum efficiency of metal halide perovskites by examining luminescence-limiting factors

Metal halide perovskites (MHPs) show superior optoelectronic properties, which give them the great potential for use in next generation light-emitting diodes (LEDs). In particular, their narrow emission linewidths can achieve ultrahigh color purity. However, the reported luminescence efficiency (LE) values are not high enough to be commercialized in displays and solid-state lightings. Moreover, the operational stability of LEDs associated with the overshooting of luminance and the high relative standard deviation of reported external quantum efficiencies are still problematic. In this perspective, we review photophysical factors that limit the photoluminescence quantum efficiency of perovskite-based LEDs. These factors are categorized into (i) weak exciton binding, (ii) nonradiative recombinations, (iii) slow cooling of long-lived hot carriers, (iv) deep-level defects, and (v) interband transition rates. We then present various physicochemical methods to effectively overcome these luminescence-limiting factors. We finally suggest some useful research directions to further improve the LE of MHP emitters as core components in displays and solid-state lightings.

Negative pressure wound therapy for soft tissue injuries around the foot and ankle

<p>Abstract</p> <p>Background</p> <p>This study was performed to evaluate the results of negative pressure wound therapy (NPWT) in patients with open wounds in the foot and ankle region.</p> <p>Materials and methods</p> <p>Using a NPWT device, 16 patients were prospectively treated for soft tissue injuries around the foot and ankle. Mean patient age was 32.8 years (range, 3–67 years). All patients had suffered an acute trauma, due to a traffic accident, a fall, or a crush injury, and all had wounds with underlying tendon or bone exposure. Necrotic tissues were debrided before applying NPWT. Dressings were changed every 3 or 4 days and treatment was continued for 18.4 days on average (range, 11–29 days).</p> <p>Results</p> <p>Exposed tendons and bone were successfully covered with healthy granulation tissue in all cases except one. The sizes of soft tissue defects reduced from 56.4 cm²to 42.9 cm²after NPWT (mean decrease of 24%). In 15 of the 16 cases, coverage with granulation tissue was achieved and followed by a skin graft. A free flap was needed to cover exposed bone and tendon in one case. No major complication occurred that was directly attributable to treatment. In terms of minor complications, two patients suffered scar contracture of grafted skin.</p> <p>Conclusion</p> <p>NPWT was found to facilitate the rapid formation of healthy granulation tissue on open wounds in the foot and ankle region, and thus, to shorten healing time and minimize secondary soft tissue defect coverage procedures.</p

Evaluation of the On-Campus Dining Service Using Importance-Performance Analysis

University foodservice is one of the largest sectors of the foodservice industry, and the college-student market is getting larger. Therefore, it is important that university foodservice needs to be monitored periodically and improved comprehensively in order to retain students as satisfied customers for on-campus foodservice. The objectives of the current study were to explore the importance and performance/satisfaction of on-campus dining service consumers, to investigate the importance-performance difference between patron and non-patron customers, and to examine the difference between gender groups. The study compared the respondents’ perceived importance and performance ratings of the dining service quality attributes using IPA. The IPA grid illustrated that food quality and sanitation fell into the Quadrant II (Keep up the Work); price into the Quadrant III (Low Priority); and service and environment into the Quadrant IV (Possible Overkill). However, according to IPA of comparison of patron versus non-patron groups and gender groups, the service attribute was allocated differently
