The valorization of industrial lignin essentially requires fractionation resulting in lower structural heterogeneity and polydispersity. So far, extensive approaches based on extraction with solvents, gradient acid precipitation, membrane-based filtration have been developed to reduce the polydispersity technical lignins. However, most reports tend overlook fraction that bonded carbohydrates or...
The clinical use of high intensity focused ultrasound (HIFU) therapy for noninvasive tissue ablation has been recently gaining momentum. In HIFU, ultrasound energy from an extracorporeal source is focused within the body to ablate tissue at the focus while leaving the surrounding organs and tissues unaffected. Most HIFU therapies are designed to use heating effects resulting from the absorption...
Thermal water from the hot springs around Bugok, South Korea, has highest discharge temperature (78 °C), and source of that heat is primary interest. The key 3He/4He ratio runs along a single air-mixing line between mantle crust, with latter accounting for 97.0–97.3%. This suggests thermal radioactive decay in granodiorite, rock intruded beneath Cetaceous era sedimentary rock. containing Na–HCO...
ThFFF with multiple detection enables monitoring the transformation of block copolymers into single chain nanoparticles stabilized by a shell (SCNP-shell). The SCNP-shell are in dynamic equilibrium nanoparticles.
