Assessing trace element (dis)equilibrium and the application of single element thermometers in metamorphic rocks

open access: yesLithos, 2018
Empirical and experimental calibration of single element solubility thermometers, such as Zr-in-rutile, Zr-in-titanite, Ti-in-zircon, and Ti-in-quartz, within the past 13 years has greatly expanded our ability to assess the pressure and temperature ...

Deep Seek to the Excited States: A Thermally‐Activated Jahn–Teller Effect Achieves Superior Sensitivity for Thermometry at Cryogenic Temperature

open access: yesAdvanced Optical Materials, EarlyView.
A Sb3+‐activated bismuth‐based halide single crystal shifts the onset temperature by ≈200 K. The confluence of the spin‐orbit interaction and the dynamic Jahn–Teller effect is responsible for maximizing the opposite emission changes at different temperatures. A high relative sensitivity (Sr) value of 18.9 % K−1 is obtained at 77 K.

On–Off Switchable Micromotors for Use in Steerable Microvehicles

open access: yesAdvanced Robotics Research, EarlyView.
Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

Fully Plant‐Based and Optically Transparent Wood Substrates with Improved Thermal Insulating Properties

open access: yesAdvanced Sustainable Systems, EarlyView.
The combination of an eco‐friendly bleaching procedure with the use of a new commercial bio‐based resin used to develop transparent wood (TW) result in a transparency level of 91% at 550 nm, alongside remarkable stability and a ≈50% reduction in thermal conductivity compared to standard glass (≈1 W m·K−1), highlighting its potential as energy‐efficient

Obtaining Orthogonal Thermal Conductivity Components from Anisotropic Thin Films Using the Pseudo Steady‐State 3ω Method

open access: yesAdvanced Theory and Simulations, EarlyView.
Measurement of thin film thermal conductivity is challenging for isotropic materials, but is even more so for films with anisotropic in‐plane properties. This work establishes the pseudo steady‐state 3ω technique as a suitable method to extract orthogonal in‐plane thermal conductivity components from thin films. Abstract Directional characterization of

Analysis of a modern method for calibrating resistance thermometers [PDF]

open access: yesE3S Web of Conferences
Resistance thermometers, as metrological instruments, are based on determining temperature through the physical quantity of resistance. These devices require periodic calibration to consistently ensure accuracy.

Hepatic ENTPD5 Is Critical for Maintaining Metabolic Homeostasis and Promoting Brown Adipose Tissue Thermogenesis

open access: yesAdvanced Science, EarlyView.
ENTPD5‐mediated conversion of extracellular adenosine triphosphate to ADP of hepatocytes is critical for maintaining hepatic glucose/lipid metabolism and promoting brown adipose tissue thermogenesis via the inhibition of adrenomedullin expression and secretion.
