Prominences: The Key to Understanding Solar Activity
, 2011 Prominences are spectacular manifestations of both quiescent and eruptive solar activity. The largest examples can be seen with the naked eye during eclipses, making prominences among the first solar features to be described and catalogued.

Prominences and magnetic activity on young single and binary stars
, 2008 In this thesis I study the magnetic activity of young stars via observations of stellar prominences on single stars and by applying the Zeeman Doppler imaging (ZDI) technique to map the magnetic fields and measure differential rotation of a young binary ...

Hydrophobicity Modulated Interfacial Water Distribution for Enhanced Kinetics of HER
Advanced Science, EarlyView.In electrocatalysis, hydrophilic structures improve interfacial water management by forming a continuous, compact water film that facilitates proton/hydrogen transport, thereby lowering the effective adsorption free energy of H*. By contrast, hydrophobic structures enable rapid gas transport and promote the capture and local enrichment of gaseous ...

Spectropolarimetry of solar prominences
, 2009 A large set of high precision full-Stokes spectropolarimetric observations of prominences in He-D3, Halpha and Hbeta lines has been recorded with the ZIMPOL polarimeter at the Gregory-Coude Telescope in Locarno. The observational technique allows us to obtain measurements free from seeing induced spurious effects.

Advanced Science, EarlyView.A piezocatalytic strategy enables simultaneous wastewater purification and hydrogen generation by harnessing mechanical energy. Complementary piezo‐induced charges are selectively directed toward oxidation and reduction pathways, achieving efficient pollutant degradation and continuous H2 evolution.

Magnetohydrodynamic Instabilities in Solar Prominences [PDF]
This work aims to understand of the nature of the magnetic environment which guides the evolution of solar prominences on both large and small scales, of which little is known.

Non-thermal line-broadening in solar prominences
, 2015 Aims. We show that the line broadening in quiescent solar prominences is mainly due to non-thermal velocities. Methods. We have simultaneously observed a wide range of optically thin lines in quiescent prominences, selected for bright and narrow ...

Advanced Science, EarlyView.This work constructed a tandem W−N−C center to simultaneously achieve the regulation of reaction pathways and optimization of charge separation efficiency. The Lewis‐acidic W6+ sites activated O2 to generate O2−$O_2^ - $, with enhanced charge separation via electronic modulation, steering U(VI) reduction down an efficient radical pathway.
