Taking climate change seriously: An analysis of op-ed articles in Spanish press

2016

In this article, we study the evolution of opinion genres regarding climate change in three Spanish newspapers ( El País, El Mundo, and ABC). Analyzing the op-ed articles in these newspapers, we observe a significant change in the evolution of opinion. While denialism was very present in conservative press in 2007, 7 years later it is almost absent from El Mundo, and its presence in ABC is much lower and inactive: this shows that scientific consensus has prevailed over time and Spanish denialism has weakened, exclusively supported by political arguments by the most conservative parties.

Region Community in Communication Theory

2014

The aim of the report is to determine how local and regional newspapers represent local communities and how their communicative integration has been promoted. Mass media, establishing community cognition about its existence, involvement into the community, identification and belonging to the community, represent a perfect model of interaction between community and communication. During the content analysis of the press publications of local newspapers of Latgale region the typological characteristics and classification are emphasized, the role of the press in the development of the region inhabitants is defined, the direction and structure of the editorial board activities, newspapers’ cont…

Structure‐Activity Relationships of Benzamides and Isoindolines Designed as SARS‐CoV Protease Inhibitors Effective against SARS‐CoV‐2

2020

Abstract Inhibition of coronavirus (CoV)‐encoded papain‐like cysteine proteases (PLpro) represents an attractive strategy to treat infections by these important human pathogens. Herein we report on structure‐activity relationships (SAR) of the noncovalent active‐site directed inhibitor (R)‐5‐amino‐2‐methyl‐N‐(1‐(naphthalen‐1‐yl)ethyl) benzamide (2 b), which is known to bind into the S3 and S4 pockets of the SARS‐CoV PLpro. Moreover, we report the discovery of isoindolines as a new class of potent PLpro inhibitors. The studies also provide a deeper understanding of the binding modes of this inhibitor class. Importantly, the inhibitors were also confirmed to inhibit SARS‐CoV‐2 replication in …

Reactivity of Nickel(II) Porphyrins in oCVD Processes—Polymerisation, Intramolecular Cyclisation and Chlorination

2019

Abstract Oxidative chemical vapour deposition of (5,15‐diphenylporphyrinato)nickel(II) (NiDPP) with iron(III) chloride as oxidant yielded a conjugated poly(metalloporphyrin) as a highly coloured thin film, which is potentially useful for optoelectronic applications. This study clarified the reactive sites of the porphyrin monomer NiDPP by HRMS, UV/Vis/NIR spectroscopy, cyclic voltammetry and EPR spectroscopy in combination with quantum chemical calculations. Unsubstituted meso positions are essential for successful polymerisation, as demonstrated by varying the porphyrin meso substituent pattern from di‐ to tri‐ and tetraphenyl substitution. DFT calculations support the proposed radical oxi…

C−C Cross-Couplings from a Cyclometalated Au(III) C∧ N Complex: Mechanistic Insights and Synthetic Developments

2021

Abstract In recent years, the reactivity of gold complexes was shown to extend well beyond π‐activation and to hold promises to achieve selective cross‐couplings in several C−C and C−E (E=heteroatom) bond forming reactions. Here, with the aim of exploiting new organometallic species for cross‐coupling reactions, we report on the Au(III)‐mediated C(sp2)−C(sp) occurring upon reaction of the cyclometalated complex [Au(CCH2N)Cl2] (1, CCH2N=2‐benzylpyridine) with AgPhCC. The reaction progress has been monitored by NMR spectroscopy, demonstrating the involvement of a number of key intermediates, whose structures have been unambiguously ascertained through 1D and 2D NMR analyses (1H, 13C, 1H‐1H CO…

«Lex Google»: Copyright Law and Internet Providers, Future Enemies or Allies?

2013

The German Federal Parliament is discussing the approval of the so-called “Lex Google” which will amend the German Copyright Act and provide for a number of improvements to the management of copyrighted content by Internet Service Providers. This paper focuses on the advantages and disadvantages linked to the diffusion of copyrighted content over the Internet and suggests that the Lex Google would benefit from taking better into account E-Commerce rules and ECJ case-law on Internet Service Providers.

Dimethyl 4,4'-(diazenedi-yl)dibenzoate at 100 K.

2013

In the asymmetric part of the unit cell of the title compound, C16H14N2O4, there are two chemically equivalent but crystallographic independent half molecules. The geometric centre of each complete molecule lies on a crystallographic inversion centre. Both molecules are almost planar [mean deviations of atoms in the two molecules are 0.032 (2) and 0.044 (2) Å] and their geometries are similar. In the crystal, molecules are arranged in columns along theaaxis. There are no intermolecular donor–acceptor distances shorter than 3.4 Å.

1,1′-[2,3,5,6-Tetramethyl-p-phenylenebis(methyleneoxy)]di-1H-benzotriazole

2009

The complete molecule of the title compound, C(24)H(24)N(6)O(2), is generated by a crystallographic inversion centre. The benzotriazole rings form dihedral angles of 2.10 (7)° with the central aromatic ring. The crystal packing is consolidated by π-π inter-actions, with centroid-centroid distances of 3.6234 (10) Å, together with weak C-H⋯π inter-actions.
