Arianna Huffington; \u27\u27Healing America: Twelve Steps to American Renewal
Arianna Huffington is a prolific author and international media mogul who started the award-winning news platform The Huffington Post.
Born on July 15, 1950, in Athens, Greece, Arianna Huffington went on to study economics at the University of Cambridge, eventually moving to the United States. She was a conservative commentator before switching to liberal politics and started the Web site The Huffington Post in 2005. The site, purchased by AOL in 2011, has gone on to become a popular and powerful online news platform. Huffington is also the author of more than a dozen books on topics ranging from feminism to corporate America to politics. In 2016, Huffington annnounced her departure from The Huffington Post to launch Thrive Global, a start-up company dedicated to health and wellness.
Huffington was initially known for her conservative political views and commentary, and she made regular television appearances to support her standpoints. But she eventually began to embrace more left-leaning platforms, including ecological activism and corporate reform
Building an Infrastructure to Support Researchers - An Interview with Redalyc's Arianna Becerril
Redalyc was one of our earliest supporters in Latin America and they’ve used ORCID to build an infrastructure that supports researchers. Redalyc offers author profile pages and tools for specific editions of scientific journals, in order to support the sustainability of Open Access in the region.

Photo‐Induced Radicals in Carbon Nitride and their Magnetic Signature
As a metal-free semiconductor, carbon nitride is a promising material for sustainable photocatalysis. From the large number of studies, it seems apparent that the photocatalytic activity is related to the number and type of defects present in the structure. Many defects are paramagnetic and photoresponsive and, for this reason, Electron Paramagnetic Resonance (EPR) spectroscopy is a powerful method to derive fundamental information on the structure – local, extended and electronic – of such defects which in turn impact the optical, magnetic and chemical properties of a material. This review aims at critically discussing the interpretation of EPR data of native and photoinduced radical defects in carbon nitride research highlighting strengths and limitations of this spectroscopic techniqu

General report. Governmental policies to fight pandemic : the boundaries of legitimate limitations on fundamental freedoms
This General Report highlights some discernible trends in the legal reaction to public health emergency caused by Covid-19. Emergencies, as the Covid-19 pandemic, put rights and freedoms systems under stress: the core of this Report, therefore, is to analyze – from a comparative perspective – the impact of the anti-pandemic measures on rights and freedoms. After a general introduction about the main features of the 2020-2022 emergency, the analysis is divided into three main parts: first, the Report identifies several trends embraced by different countries as regards the resort to international and supranational derogation clauses as well as to domestic emergency frameworks to tackle the pandemic. Second, the Report analyzes the effect of anti-Covid-19 policies on most affected rights and freedoms (e.g. freedom of movement, freedom of assembly, religious freedom, economic freedoms but also political rights, communication and information rights and the protection of vulnerable groups). In carrying out this analysis, the Report takes into consideration relevant case law, especially be supreme and constitutional courts. Third, the Author highlights some common dynamics in the management of Covid-19 public health crisis (e.g. the marginalization of Parliaments and the outreach of Executives, the impossibility for courts to review emergency measures, the new role of science and technology in decision-making), assessed thanks to the precise analysis of individual national reports. Lastly, the concluding remarks draw some guidelines in order to improve the response to potential forthcoming emergencies
Singlet‐Triplet Energy Inversion in Carbon Nitride Photocatalysts
Time-resolved EPR (TR-EPR) demonstrates the formation of well-defined spin triplet excitons in carbon nitride. This permits to experimentally probe the extent of the triplet wavefunction which delocalizes over several tri-s-triazine units. Analysis of the temperature dependence of the TR-EPR signal reveals the mobility of the triplet excitons. By employing monochromatic light excitation in the range 430-600 nm, the energy of the spin triplet is estimated to be ≈0.2 eV above the conduction band edge, proving that the triplet exciton lies above the corresponding singlet. Comparison between amorphous and graphitic forms establishes the singlet-triplet inversion as a general feature of carbon nitride materials
Morphology and Light‐Dependent Spatial Distribution of Spin Defects in Carbon Nitride
Carbon nitride (CN) is a heterogeneous photocatalyst that combines good structural properties and a broad scope. The photocatalytic efficiency of CN is associated with the presence of defective and radical species. An accurate description of defective states—both at a local and extended level—is key to develop a thorough mechanistic understanding of the photophysics of CN. In turn, this will maximise the generation and usage of photogenerated charge carriers and minimise wasteful charge recombination. Here the influence of morphology and light-excitation on the number and chemical nature of radical defects is assessed. By exploiting the magnetic dipole-dipole coupling, the spatial distribution of native radicals in CN is derived with high precision. From the analysis an average distance in the range 1.99–2.34 nm is determined, which corresponds to pairs of radicals located approximately four tri-s-triazine units apart
