Ultraviolet spectroscopy of cool stars
Journal of the Optical Society of America B, 1988 A review is given of some developments in the study of UV emission-line spectra of cool stars, including the Sun, in recent years. Although early work on solar-line identifications depended heavily on compilations of energy levels from laboratory studies [ Natl. Stand. Ref. Data Ser. Natl. Bur. Stand.35 ( 1971);Natl. Bur. Stand. (U.S.) Circ.488 ( 1950,

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions
Advanced Functional Materials, EarlyView.This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Advanced Functional Materials, EarlyView.DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer
Advanced Functional Materials, EarlyView.Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics
Advanced Functional Materials, EarlyView.We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Selective Membrane Transport Systems studied by Solid-State NMR Spectroscopy [PDF]
, 2009 Membranes border cells from their environment. Thus, they belong to the basic prerequisites for life as we know it. Within cells, membranes are used to establish compartments dedicated to specific tasks such as providing local proximity of components ...

Nondestructive varnish identification by ultraviolet fluorescence spectroscopy
, 2007 International audienceThe identification of the chemical nature of varnish is essential for art restorers in order to choose a suitable solvent during its removal. Until today, such identification has been performed using chemical analysis after sampling.
