Heterogeneous Exhumation Mechanisms in Neoproterozoic Collisional Metamorphism: P–T Constraints From Pelotas and Punta del Este Terranes, Southern Brazil and Uruguay

open access: yesGeological Journal, EarlyView.
Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...

Microwave Imaging with Open-Ended Coaxial Probes

open access: yes
This work proposes an innovative approach to microwave imaging by combining robotics with open-endedcoaxial probes. Traditionally, open-ended coaxial probes have been employed for precise dielectric measurements. However,their integration with robotics introduces a novel dimension,enabling dynamic movement and positioning during processes. This synergy

Minimally Invasive Sampling for Molecular Profiling of Lymph Nodes Using a Modified Acupuncture Needle

open access: yesiMetaMed, EarlyView.
Schematic illustration of the preparation of His@PDA@Needle, a modified acupuncture needle designed for minimally invasive sampling of lymph node‐derived DNA for molecular profiling. ABSTRACT Current clinical liquid biopsy approaches predominantly rely on blood‐derived biomarkers, which are often limited in sensitivity.

Architecting nano‐Al/HMX/CuO energetic micro‐units unlocks superior interface and highly efficient combustion

open access: yesInfoMat, EarlyView.
Improving the dispersion of nano‐aluminum is of great importance in explosives and propellants. The spherical Al/HMX/CuO energetic micro‐units were prepared using microchannel technology, which significantly improved the uniformity and dispersion of nano‐Al. It also enhanced the mass and heat transfer efficiency between the fuel and oxidizer components,

Nuclear‐Spin Hyperpolarization of Biomolecules by Optically Enhanced NMR at Ultra‐High Field

open access: yesJournal of the Chinese Chemical Society, EarlyView.
This study shows that the sensitivity of liquid‐state NMR spectroscopy can be dramatically increased, with enhancement factors up to 160‐fold on a 1.1 GHz ultra‐high‐field NMR spectrometer. This advance exploits low‐concentration photochemically induced dynamic nuclear polarization (LC‐photo‐CIDNP) and it enables facile atomic‐resolution detection of ...
