Abstract Despite multiple research approaches to prevent bacterial colonization on surfaces, device‐associated infections are currently responsible for about 50% of nosocomial in Europe and significantly increase health care costs, which demands development advanced antibacterial surface coatings. Here, novel antimicrobial composite materials incorporating zinc oxide nanoparticles (ZnO NP) into biocompatible poly( N ‐isopropylacrylamide) (PNIPAAm) hydrogel layers prepared by mixing the...
As a growing public health concern, the worldwide spread of antimicrobial resistance urges development new therapies. Antibacterial photodynamic therapy (a-PDT) may be an alternative to conventional antibiotic therapy. Herein we report synthesis and characterization seven original reactive oxygen species (ROS)-producing ruthenium(II) polypyridyl complexes. These are part collection 17 derivatives varying in terms nature substituent(s), molecular symmetry, electrical charge, counterions. They...
We report a triazole-based trinuclear Fe<sup>II</sup> complex as the first example that displays sharp and complete spin transition. The strong ferro-elastic coupling between three metal centers was identified source of concerted

New Fe(II) coordination polymeric neutral chains of formula [Fe(aqin)2(μ2-M(CN)4)] (M = Ni(II) (1) and Pt(II) (2)) (aqin Quinolin-8-amine) have been synthesized characterized by infrared spectroscopy, X-ray diffraction, magnetic measurements. The crystal structure determinations 1-2 reveal in both cases a one-dimensional which the planar [M(CN)4](2-) anion acts as μ2-bridging ligand, two aqin molecules chelating coligands. Examination intermolecular contacts compounds reveals that main are...
Antimicrobial photodynamic therapy (aPDT) depends on a variety of parameters notably related to the photosensitizers used, pathogens target and environment operate. In previous study using series Ruthenium(II) polypyridyl ([Ru(II)]) complexes, we reported importance chemical structure both their photo-physical/physico-chemical properties efficacy for aPDT. By employing standard in vitro conditions, effective [Ru(II)]-mediated aPDT was demonstrated against planktonic cultures Pseudomonas...
Reactions between CuCl2 and K2tcpd (tcpd2- = [C10N6]2- (C[C(CN)2]3)2-) in the presence of neutral co-ligands (bpym 2,2'-bipyrimidine, tn 1,3-diaminopropane) aqueous solution yield new compounds [Cu2(bpym)(tcpd)2(H2O)4] x 2H2O (1), [Cu(tn)(tcpd)] (2), [Cu(tn)2(tcpd)] H2O (3), which are characterized by X-ray crystallography magnetic measurements. Compound 1 displays a one-dimensional structure bpym ligand, acting with bis-chelating coordination mode, leads to [Cu2(bpym)]4+ dinuclear units...
The introduction of interdisciplinarity and industry-academia collaborations (IAC) into higher education institutions (HEIs) curricula as tools for promoting sustainable development has been debated both in academic non-academic contexts. While overall rising trends the acceptance IAC exist, research stressed difficulty implementation practices. We conducted eight focus groups at six European Universities (members SEA-EU alliance) analysed transcripts using Braun Clarke’s reflexive thematic...
Abstract One‐pot reactions in aqueous solutions of the polynitrile anion dcne − {2,2‐dicyano‐1‐ethoxyethenolate = [(CN) 2 CC(O)OEt)] ] with M II ions (M Mn, Fe, Co, Cu) presence bpym (2,2′‐bipyrimidine) afford first mixed dcne/bpym compounds [M (bpym)(dcne) 4 (H O) ( 1 : Mn; Co) and ]·2H O 3 Fe; Cu). The new have been characterized by IR spectroscopy X‐ray crystallography. Compounds are isostructural, each metal ion being located an MN 5 pseudo‐octahedral environment three N atoms coming...
An emerging trend toward development of metal-organic frameworks (MOF) consists in using preformed complexes as building blocks able to assemble via coordination chemistry and/or charge-assisted H-bonding. Within this framework and depending only on the experimental conditions, reactions [Zr(C 2O 4) 4] 4− anion with [DabcoH 2] 2+ dication (Dabco = 1,4-diazabicyclo[2. 2. 2]octane) selectively afford compounds {K 2(DabcoH 2)[Zr(C 4]}·6.5H ( 1), {(DabcoH 2) 2[Zr(C 4]}·3H 2), 4]}·5.5H 3), or...
Hybrid nanocrystals (HNCs), based on ZnO nanorods (NRs) decorated with magnetic Fe-based domains, were synthesized via a colloidal seeded-growth method. The approach involved heterogeneous nucleation of Fe size-tailored nanorod seeds in noncoordinating solvent, followed by partial surface oxidation the former to corresponding Fe@FexOy core@shell domains. HNCs variable population and size nanodomains could be depending reactivity seeds. structure-property relationships these carefully...
Reaction of the two-coordinate 'assembling complex-ligand' [Cu(tn)]2+ with building block [Cr(CN)6]3- leads to a unique two-dimensional Cu-Cr cyano-bridged ferromagnet unusual mu 3- and 4-bridging units.
A new polynuclear copper(II) complex [Cu7(OH)6Cl2(pn)6(H2O)2](C(CN)3)4Cl2 with hydroxo-bridging ligands has been prepared; the centrosymmetric cluster cation can be described as two Cu4O3Cl distorted cubane units sharing one copper cation.
The new two-dimensional coordination compound {[CuII(tn)]2[FeII(CN)6]}·KCl·5H2O (1) (tn = 1,3-diaminopropane), generated by six –Fe–CN–Cu– bridges, shows weak ferromagnetic interactions between the nearest Cu(II) ions through diamagnetic [Fe(CN)6]4− anion.
