The study of purely organic room-temperature phosphorescence (RTP) has drawn increasing attention because of its considerable theoretical research and practical application value. Currently, organic RTP materials with both high efficiency (Φ > 20%) and a long lifetime (τ > 10 s) in air are still scarce due to the lack of related design guidance. Here, a new strategy to increase the phosphorescence performance of organic materials by integrating the RTP host and RTP guest in one doping system to form a triplet exciplex, is reported. With these materials, the high-contrast labeling of tumors in living mice and encrypted patterns in thermal printing are both successfully realized by taking advantage of both the long afterglow time (up to 25 min in aqueous media) and high phosphorescence efficiency (43%).

Herein, 1,3,5-benzenetricarboxylate (BTC) intercalation and oxygen vacancy engineering are proposed to enhance the electrochemical performance of layered double hydroxide (LDH) nanosheets. The optimized LDH exhibits a remarkable capacity of 426 mAh g at 3 A g and 70% capacity retention after 15 000 cycles, attributed to improved ion transport, abundant active sites, and structural stability.

High-performance, low-cost electrocatalysts are essential for freshwater-independent seawater electrolysis. We design a SWCNT-supported (FeCoNiMnCr)O high-entropy spinel oxide by a hydrothermal method and air-firing, where the conductive network enhances charge transfer and active site exposure. The catalyst achieves 282 mV@10 mA cm with 100 h stability in alkaline seawater.

Symphonia globulifera (Clusiaceae) has emerged as a model organism in tropical forest ecology and evolution due to its significant ecological role and complex biogeographical history. Originating from Africa, this species has independently colonized Caribbean, Central and South America three times, becoming a key component of tropical ecosystems across these regions. Despite the ecological importance of S.

Objectives: The risk of major venous thromboembolism (VTE) among patients with COVID-19 is high but varies with disease severity. Estimate the incidence of lower extremity deep venous thrombosis (DVT) in critically ill hospitalized patients with COVID-19, validate the Wells score for DVT diagnosis, and determine patients' prognosis.
Methods: This was an observational follow-up study in the context of the diagnosis and prognosis of DVT.

Background: Perforation of artery causing bleeding is a rare but serious complication of percutaneous coronary intervention (PCI), with potentially life-threatening consequences. Prompt recognition and management are crucial, particularly in high-risk patients or complex procedures. Coils are essential tools for sealing perforated or ruptured vessels, preventing further haemorrhage and stabilising the patient.
