Size of coronal structures in active stellar coronae from the detection of X-ray resonant scattering [PDF]
, 2005 We have analyzed high-resolution X-ray spectra of a large sample of active stars observed with the High Energy Transmission Grating Spectrometer on Chandra in order to investigate the properties of optical thickness of the coronal plasma. The analysis of

HOT GASEOUS CORONAE AROUND SPIRAL GALAXIES: PROBING THE ILLUSTRIS SIMULATION [PDF]
, 2014 The presence of hot gaseous coronae around present-day massive spiral galaxies is a fundamental prediction of galaxy formation models. However, our observational knowledge remains scarce, since to date only four gaseous coronae have been detected around ...

High‐Efficiency Quantum Defect Generation in Carbon Nanotubes via Oxygen‐Free Photochemistry
Advanced Functional Materials, EarlyView.We show that oxygen plays an important role in quantum defect formation in carbon nanotubes and identify reaction conditions to create a range of different quantum defects for photonics and biosensing. ABSTRACT Single‐walled carbon nanotubes (SWCNTs) offer potential for a wide range of applications from optoelectronic devices to biomedical diagnostics.

Endosomal Escape of siRNA Polyplexes: A Molecular Dynamics Perspective on Underlying Mechanisms
Advanced Functional Materials, EarlyView.Molecular dynamics simulations reveal distinct endosomal escape mechanisms of siRNA nanoparticles, ranging from electrostatic membrane attachment to hydrophobic membrane fusion. Hydrophobic residues and anionic endosomal lipids emerge as key determinants of membrane disruption, linking molecular interactions to experimental delivery performance and ...

Prospects for ALMA Studies of the Solar-Stellar Connecon
, 2016 ALMA provides a splendid opportunity to observe a wide range of star types at millimeter wavelengths to investigate the solar-stellar connection. I will compare the sensitivities and wavelength coverages of ALMA and the JVLA to highlight the discovery ...

X-ray coronae and stellar magnetospheres
, 2010 Chandra's spectroscopic resolving power allows us to measure velocity shifts down to similar to 30 km/s in line profiles. Observations covering > 2 P(rot) are needed to disentangle flaring and quiescent corona! emission. The rotational modulation in X-
