The Politicization of European Union Trade Policy: Radical-Left Euroskeptic Opposition to the Transatlantic Trade and Investment Partnership

2021

This study aims to analyze the correlation between radical-left Euroskeptic (RLE) activity and European Union (EU) trade policy by focusing on the Transatlantic Trade and Investment Partnership (TTIP). At the beginning of TTIP negotiations, the agreement was not high on political agendas and was not a major concern within European society. Thus, its salience was low. This initial lack of interest stemmed from the fact that the TTIP, as an economic and technical issue, did not draw public attention. This study shows that RLEs profoundly affected public opinion on the TTIP by increasing its salience during the European parliamentary elections in 2014 in France and Germany. Second, RLEs involv…

Recent Advances in Photocatalytic Functionalization of Quinoxalin‐2‐ones

2020

Quinoxalin‐2(1H)‐one is an important class of nitrogen heterocycle in medicinal and pharmaceutical industry, which became a synthetic target in organic chemistry in recent years. This review covers the recent advances in the functionalization of this particular nitrogen heterocycle through photocatalysis.

Liquid Crystalline Orientation of Semiconducting Nanorods in a Semiconducting Matrix

2008

This paper describes the synthesis of narrowly distributed block copolymers consisting of a hole conducting triarylamine block and an anchor block via RAFT polymerization. The anchor block is thereby introduced via a reactive ester approach. Block copolymers with dopamine anchor groups bind to oxidic semiconductors like TiO 2 , SnO 2 , and ZnO. Thus, it becomes possible to cover inorganic electron conducting (acceptor) nanomaterials with a corona of an organic hole conducting (donor) polymer like poly(triphenylamine), giving new hybrid materials. The poly(triphenylamine) grafted to inorganic nanorods allows the preparation of stable nanorod dispersions in appropriate solvents. At higher con…

Conducting Polymer with Orthogonal Catechol and Disulfide Anchor Groups for the Assembly of Inorganic Nanostructures

2017

To combine several inorganic components with organic material in a controlled special and permanent manner still remains a difficult issue. Two specifically functionalized block copolymers were synthesized separately and combined in a second step. A heterofunctional poly(ethylene glycol) (PEG) block copolymer bearing a single amino unit, a short PEG spacer, and multiple catechol functionalities was obtained via anionic ring-opening polymerization (AROP). Using the reversible addition–fragmentation chain transfer (RAFT) radical polymerization technique, a semiconducting block copolymer with carbazole side groups was obtained. The second polyacrylate block contained reactive ester groups and …

Synthesis and characterization of novel organic–inorganic hybrid block copolymers

2004

Novel organic–inorganic hybrid block copolymers based on poly(methylsilsesquioxanes) (PMSSQs) have been synthesized. Two routes to functionalized PMSSQs are presented and from both atom transfer radical polymerization of methylmethacrylate could be performed. Copolymers with different block ratios have been polymerized and were characterized. In particular, thermal properties were investigated by TGA and the promising thermal decomposition behaviour makes the copolymers potential candidates as pore generators in future nanoporous materials. Additionally, these copolymers were analysed as surface coatings of regular PMMA. Contact angle measurements proved the dramatic effect on the surface p…

Conceptual Confusion is Not Always a Bad Thing – The Curious Case of European Radical Right Studies

2018

Over the course of many years, as a teacher, scholar, and friend, Ruth Zimmerling has impressed on me the importance of precisely defining one’s concepts. After all, if there is no agreement on the intension and extension of a concept, it is impossible “to assess the truth or falsity or, more generally, the correctness or incorrectness, of propositions, hypotheses or theories” (Zimmerling 2005: 15). The statement is almost self-evident: Without precisely defined concepts, the whole endeavour of science becomes pointless, and scholarly discourses are bound to turn into dialogues of the deaf.

Quantum chemical calculations of formyl radicals

1975

The ground state (2 A′) of the fluoroformyl radical, FCO, has been investigated by the unrestricted Hartree-Fock method. Pulay's force method for open-shell systems has been applied to calculate the complete quadratic force field and the diagonal cubic force constants. The force relaxation method has been used to determine the equilibrium geometry of FCO: . Adjusting the diagonal force constants to the observed vibrational frequencies of 19F12C16O and taking the values for the off-diagonal force constants from the UHF calculations, the force field of FCO is found to be: . This force field is compared with experiment and with the force fields of HCO, H2CO, and F2CO. The ground state of the F…
