Published: September 2018

Thermal energy storage and release in aliphatic phase-change materials are actively controlled by adding azobenzene-based photo-switches. UV activation of the additives induces supercooling of the composites, allowing for longer thermal storage at lower temperatures. The mechanism of this process is studied by comparing phase change behavior across diverse materials.

Radiofrequency ablation (RFA) is an interventional procedure that has been used to treat chronic back pain for over 50 years; this unique case report demonstrates the effectiveness of pulsed radiofrequency ablation (PRFA) on the dorsal root ganglion (DRG) in the treatment of chronic radicular pain (Russo et al., 2021, J Pain Res, 14, 3897). The RFA provides pain relief by using thermal energy to disrupt peripheral nerves carrying nociceptive signals back to the central nervous system (Abd-Elsayed et al.

Background: The spatial resolution of new, photon counting detector (PCD) CT scanners is limited by the size of the focal spot. Smaller, brighter focal spots would melt the tungsten focal track of a conventional X-ray source.

Purpose: To propose focal spot multiplexing (FSM), an architecture to improve the power of small focal spots and thereby enable higher resolution clinical PCD CT.

Crucial role of subsurface ocean variability in tropical cyclone genesis.

Nat Commun

Department of Atmospheric and Oceanic Science, University of Maryland, College Park, MD, USA.

The upper ocean provides thermal energy to tropical cyclones. However, the impacts of the subsurface ocean on tropical cyclogenesis have been largely overlooked. Here, we show that the subsurface variabilities associated with the variation in the 26 °C isothermal depth have pronounced impacts on tropical cyclogenesis over global oceans.

Gold-Cerium bimetallic Star-Shaped nanoplatform for synergistic tumor therapy with nanozyme Catalytic/Photothermal/Chemotherapy.

J Colloid Interface Sci

The Education Ministry Key Lab of Resource Chemistry, Joint International Research Laboratory of Resource Chemistry, Ministry of Education, Shanghai Frontiers Science Center of Biomimetic Catalysis, and Shanghai Key Laboratory of Rare Earth Functional Materials, College of Chemistry and Materials Science, Shanghai Normal University, Shanghai 200234 China. Electronic address:

A gold-cerium bimetallic asteroid nanoplatform (CeO@GNSs/Myr-HA) was obtained by electrostatically adsorbing ultra-small cerium dioxide (CeO) onto gold nanostars (GNSs) and further loading myricetin (Myr) and hyaluronic acid (HA). This nanoplatform exhibited three types of enzymatic properties-that is, GOD (glucose-oxidase), POD (peroxidase) and GSH-Ox (glutathione oxidase) mimicking catalytic activities. These enzymatic properties work together to effectively induce apoptosis in tumor cells.
