We present the science and technology roadmap for graphene, related two-dimensional crystals, hybrid systems, targeting an evolution in technology, that might lead to impacts benefits reaching into most areas of society. This was developed within framework European Graphene Flagship outlines main targets research as best understood at start this ambitious project. provide overview key aspects graphene materials (GRMs), ranging from fundamental challenges a variety applications large number...
Abstract Drosophila have been used as model organisms to explore both the biophysical mechanisms of animal magnetoreception and possibility that weak, low-frequency anthropogenic electromagnetic fields may biological consequences. In cases, presumed receptor is cryptochrome, a protein thought be responsible for magnetic compass sensing in migratory birds variety behavioural responses insects. Here, we demonstrate photo-induced electron transfer reactions melanogaster cryptochrome are indeed...
A white light-emitting diode (LED) with emission between 420 and 700 nm a supercontinuum (SC) source 450 2500 have been compared for use in evanescent wave broadband cavity-enhanced absorption spectroscopy (EW-BB-CEAS). The method is calibrated using dye known absorbance. While the LED more economic as an excitation source, SC superior both terms of baseline noise (noise equivalent absorbances lower than 10(-5) to 10(-4) absorbance units (a.u.)) accuracy measurement; these levels are...
Broadband cavity-enhanced absorption spectroscopy has been used to record, in real time, the spectrum of microlitre volume aqueous phase droplets within a microfluidic chip assembly. Using supercontinuum radiation and broadband coated external mirrors, full visible (430 nm < λ 700 nm) each passing droplet is acquired situ at high repetition rates (273 Hz/3.66 ms acquisition time) sensitivity (αmin 10−2 cm−1). The possibilities for further improvements rate using custom designed chips are discussed.
The study of radical pair intermediates in biological systems has been hampered by the low sensitivity optical techniques usually employed to investigate these highly reactive species. Understanding physical principles governing spin-selective and magneto-sensitive yields kinetics their reactions is essential identifying mechanism bird migration, might have significance discussion potential health hazards electromagnetic radiation. Here, we demonstrate powerful capabilities cavity-enhanced...
Broadband cavity-enhanced absorption spectroscopy (BBCEAS) is shown to be a sensitive method for the detection of magnetic field effects (MFEs) in two flavin-based chemical reactions which are simple models cryptochrome magnetoreceptors. The advantages optical cavity-based and (pseudo-white-light) supercontinuum radiation have been combined provide full spectral coverage across whole visible spectrum (425 < λ 700 nm). This region covers absorbance spectra flavin mononucleotide (FMN) adenine...
Abstract Cavity enhanced absorption spectroscopy (CEAS) combined with phase-sensitive detection is employed to study the effects of static magnetic fields on radical recombination reactions. The chemical system comprises photochemically generated thionine semiquinone and a 1,4-diazabicyclo[2.2.2]octane (DABCO) cationic in micellar solution sodium dodecyl sulphate. Data obtained using modulated CEAS technique, describing field effect (MFE) reaction yields, are shown be superior those...
