Regular BiBr5 chains of trans-connected octahedra are stabilized by methyviologen cations. The Bi3+ electron lone pair is sterochemically activated below −30 °C, leading to an acentric polar phase, and this is correlated with an increase of the band gap, and with the transfer from a para- to a ferroelectric phase.

Using a slow liquid–gas diffusion method, the mixed-valence viologen salt (MV)2(BF4)3 (1) and the radical cation salt (MV)(BF4) (2) are crystallized. Both structures contain regular stacks of MV˙+ radical cations (2) or alternating MV˙+ and MV2+ entities (1). A short intrastack intermolecular separation (3.23 Å) unprecedently reveals strong interactions between MV2+ and MV˙+ in 1.

The search for hybrid organic-inorganic materials remains a great challenge in the field of ferroelectrics. Following the discovery of the room temperature ferroelectric material (MV)[BiI3Cl2] (MV2+: methylviologen) exhibiting the highest polarization value in the field of hybrid ferroelectrics, we report here nine new hybrids with the general formulation (MV)[M(III)X5−xX′x] (M=Bi, Sb; X, X′=Cl, Br, I): (MV)[BiCl3.3Br1.7] (1), (MV)[BiCl1.3Br3.7] (2), (MV)[BiBr3.2I1.8] (3), (MV)[SbCl5] (4), (MV)[SbBr5] (5), (MV)[ ...

The search for hybrid organic-inorganic materials, which have the great advantage that they can be synthesized at moderate temperature (T < 200 °C), remains a great challenge in the field of ferroelectrics. Here, a room-temperature ferroelectric material with interesting characteristics, (MV)[BiI(3)Cl(2)] (MV(2+) = methylviologen), is reported. Its structure is based on polar inorganic chains resulting from a remarkable Cl/I segregation induced by methylviologen entities, which coincide with the fourfold ...

We leveraged the largely untapped resource of electronic health record data to address critical clinical and epidemiological questions about Coronavirus Disease 2019 (COVID-19). To do this, we formed an international consortium (4CE) of 96 hospitals across five countries (www.covidclinical.net). Contributors utilized the Informatics for Integrating Biology and the Bedside (i2b2) or Observational Medical Outcomes Partnership (OMOP) platforms to map to a common data model. The group focused on temporal ...

We report room-temperature synthesis of lead- and iodide-deficient α-[HC(NH2)2]PbI3 perovskites (abbreviated d-α-FAPI, FA+ = formamidinium), with the general formula (A',FA)1+ x[Pb1- xI3- x] (with A' = hydroxyethylammonium (HEA+) or thioethylammonium (TEA+) cations, 0.04 ≤ x ≤ 0.15). These materials retain a 3D character of their perovskite network despite incorporation of large HEA+ or TEA+ cations, demonstrating that the Goldschmidt tolerance factor can be bypassed. We found that thin films of (TEA,FA)1+ x[ ...

Human Serum Albumin is the most abundant protein of the plasma and displays a wide range of non-oncotic properties such as antioxidant activity, distribution in tissues and organs of binding molecules and clearance of toxic compounds. Albumin is susceptible to numerous post-translational modifications and particularly related to its free thiol group at Cys34 which is the main circulating scavenger of reactive oxygen species. The characterization of these modifications is of high interest for the ...

In breast cancer, Pax-5 promotes pro-epithelial features and suppresses malignant cancer processes. However, the molecular mechanism of this antitumor activity remains largely unknown. This study aimed to identify the cellular roles of Pax-5-regulated miRNAs in breast cancer progression.After transient transfection of Pax-5 in MDA-MB-231 breast cancer cells, Pax-5-regulated miRNA expression was examined by next-generation sequencing. The identified Pax-5-regulated miRNAs were then validated by qRT- ...

3D and 2D hybrid perovskites, which have been known for more than 20 years, have emerged recently as promising materials for optoelectronic applications, particularly the 3D compound (CH3 NH3 )PbI3 (MAPI). The discovery of a new family of hybrid perovskites called d-MAPI is reported: the association of PbI2 with both methyl ammonium (MA+ ) and hydroxyethyl ammonium (HEA+ ) cations leads to a series of five compounds with general formulation (MA)1-2.48x (HEA)3.48x [Pb1-x I3-x ]. These materials, which are lead- ...

Biodegradable wastes produced seasonally need an upstream storage, because of the requirement for a constant feeding of anaerobic digesters. In the present article, the potential of co-ensiling biodegradable agro-industrial waste (sugar beet leaves) and lignocellulosic agricultural residue (wheat straw) to obtain a mixture with low soluble sugar content was evaluated for long-term storage prior to anaerobic digestion. The aim is to store agro-industrial waste while pretreating lignocellulosic biomass. ...

Venomous animals have developed a huge arsenal of reticulated peptides for defense and predation. Based on various scaffolds, they represent a colossal pharmacological diversity, making them top candidates for the development of innovative drugs. Instead of relying on the classical, low-throughput bioassay-guided approach to identify innovative bioactive peptides, this work exploits a recent paradigm to access to venom diversity. This strategy bypasses the classical approach by combining high-throughput ...

Despite significant analytical improvements during this last decade, characterizing the whole integrity of monoclonal antibodies during their bioproduction remains a challenge. In this study, we report a new analytical approach to evaluate the overall heterogeneity/integrity of mAbs by LC-MS after combined proteolysis at their lower- and upper-hinge sites using the immunoglobulin-degrading enzymes IdeS and IgdE respectively. The whole sample preparation did not use any harsh conditions such as low ...

A slow liquid–gas diffusion method in strong acid conditions has allowed stabilizing for the first time in the solid state the diprotonated form of the 4,4′-bipyridine-N,N′-dioxide (bp4do), H2bp4do2+ as two polymophs of the chloride salt (H2bp4do)Cl2, while in the presence of a metallic salt M(III)Br3 (M = Bi, Sb), the monoprotonated form Hbp4do+ is mainly stabilized as (Hbp4do)2[Sb2Br8] and (H2bp4do)(Hbp4do)4[Bi4Br18]·2H2O. The dehydration of this last phase leads to (H2bp4do)(Hbp4do)4[Bi4Br18]. In the ...

Modifications made in our laboratory to the standard purification protocol (J. E. Folk and S. I.

A novel porous coordination polymer [Mn(pc3)(H2O)2]·xH2O (3 < x < 4) is synthesized in water at pH = 7 using the anionic viologen-carboxylate ligand 4,4'-bipyridinium,1,1'-bis-(2,4-dicarboxyphenyl) (pc32-). Dehydration of the material results in the formation of open pores containing two types of accessible Lewis acid sites: exposed Mn2+ cations and N+ atoms of viologen units.
