Advanced 1.5-μm emitting materials that can be used to fabricate electrically driven light-emitting devices have the potential for developing cost-effective light sources for integrated silicon *** erbium(Er^(3+))in organic materials can give bright 1.5-μm luminescence and provide a route for realizing 1.5-μm organic light emitting diodes(OLEDs).However,the Er3+electroluminescence(EL)intensity needs to be further improved for device ***,an efficient 1.5-μm OLED made from a sensitized organic Er3+co-doped system is realized,where a“traditional”organic phosphorescent molecule with minimal triplet–triplet annihilation is used as a chromophore *** chromophore provides efficient sensitization to a co-doped organic Er^(3+) complex with a perfluorinatedligand *** large volume can protect the Er^(3+) 1.5-μm luminescence from vibrational *** average lifetime of the sensitized Er^(3+) 1.5-μm luminescence reaches ~0.86 ms,with a lifetime component of 2.65 ms,which is by far the longest Er^(3+) lifetime in a hydrogen-abundant organic environment and can even compete with that obtained in the fully fluorinated organic Er^(3+) *** optimal sensitization enhances the Er^(3+) luminescence by a factor of 1600 even with a high concentration of the phosphorescent molecule,and bright 1.5-μm OLEDs are obtained.

Thiel-behnke Corneal Dystrophy in a Young Man in Denmark—A Case Report

引用

Open Journal of Ophthalmology 2024年第3期14卷 208-217页

作者： Sara bøgelund Rasmussen Anders peter Søndergaard Department of Ophthalmology University Hospital of Southern Denmark Vejle Hospital Denmark

background: This case report presents a case of bilateral Thiel-behnke corneal dystrophy in Denmark. Thiel-behnke is an autosomal dominant inherited epithelial-stromal TGFbI dystrophy causing visual impairment. Methods and Results: This case study presents a 24-year-old Lithuanian man, with no previous ocular history, who had experienced slowly progressive visual impairment since his childhood. He was examined at the Department of Ophthalmology at Vejle Hospital and Aarhus University Hospital, where he was diagnosed with bilateral Thiel-behnke corneal dystrophy. Histology confirmed the diagnosis. A lamellar corneal transplantation was performed in the right eye;however, due to epithelial growth under the corneal graft, it was later decided to redo the operation. Following the operations, the patient experienced a visual improvement in best corrected visual acuity (bCVA) from 0.1 (20/25 Snellen equivalent) to 0.3 (20/40 Snellen equivalent) in his right eye. Conclusions: This case of Thiel-behnke corneal dystrophy is to our knowledge the first reported case in Denmark.

Organic dye pollutants present in wastewater pose a significant global challenge. Among pollutants, the synthetic dye Rhodamine b(Rb) stands out due to its non-biodegradable nature and associated neurotoxic, carcinogenic,and respiratory irritant properties. Extensive research has been conducted on the efficacy of adsorption and photodegradation techniques for the removal of Rb from wastewater. While adsorption and advanced oxidation processes(AOPs) have gained considerable attention for their effectiveness in recent years, the underlying behaviors and mechanisms of these technologies remain incompletely understood. Therefore, a comprehensive of recent research progress in this domain is imperative to clarify the basics and present the up-to-date *** review provides an in-depth exploration of the fundamentals, advancements, and future trajectories of Rb wastewater treatment technologies, mainly encompassing adsorption and photodegradation. This work starts with a general introduction of outlining the sources, toxicity, and diverse applicable removal strategies. Subsequently, it thoroughly examines crucial techniques within non-photochemical, photochemical, and adsorption technologies, such as UV light assisted AOP, catalyst assisted AOP, ozonation, Fenton system, electrochemical AOP, and adsorption technology. The primary objective is to furnish a broad overview of these techniques,elucidating their effectiveness, limitations, and applicability. Following this, the review encapsulates state-of-theart computational simulations pertaining to Rb adsorption and interactions with clays and other ***, it delves into column adsorption of Rb dye, and elucidates various influencing factors, including bed height, feed concentration, pollutant(Rb) feeding or flow rate, and column regeneration.

Context-aware reinforcement learning for cooling operation of data centers with an Aquifer Thermal Energy Storage

Energy and AI

Energy and AI 2024年第3期17卷 233-246页

作者： Lukas Leindals peter Grønning Dominik Franjo Dominković Rune Grønborg Junker Department of Applied Mathematics and Computer Science Technical University of DenmarkDenmark

Data centers are often equipped with multiple cooling units. Here, an aquifer thermal energy storage (ATES) system has shown to be efficient. However, the usage of hot and cold-water wells in the ATES must be balanced for legal and environmental reasons. Reinforcement Learning has been proven to be a useful tool for optimizing the cooling operation at data centers. Nonetheless, since cooling demand changes continuously, balancing the ATES usage on a yearly basis imposes an additional challenge in the form of a delayed reward. To overcome this, we formulate a return decomposition, Cool-RUDDER, which relies on simple domain knowledge and needs no training. We trained a proximal policy optimization agent to keep server temperatures steady while minimizing operational costs. Comparing the Cool-RUDDER reward signal to other ATES-associated rewards, all models kept the server temperatures steady at around 30 °C. An optimal ATES balance was defined to be 0% and a yearly imbalance of −4.9% with a confidence interval of [−6.2, −3.8]% was achieved for the Cool 2.0 reward. This outperformed a baseline ATES-associated reward of 0 at −16.3% with a confidence interval of [−17.1, −15.4]% and all other ATES-associated rewards. However, the improved ATES balance comes with a higher energy consumption cost of 12.5% when comparing the relative cost of the Cool 2.0 reward to the zero reward, resulting in a trade-off. Moreover, the method comes with limited requirements and is applicable to any long-term problem satisfying a linear state-transition system.
