the ability of uropathogenic e. coli (upec) to cause symptomatic uti is associated with the expression of a variety of virulence factors. biofilm formation enables upec to resist the flow of urine and increases its tolerance to antimicrobials and the host immune response. the measurement of biofilm formation in vitro is affected by the type of culture medium used. the aim of this study was to e...

A novel mixed-ligand copper(II) complex with N-(p-methoxybenzyl)-iminodiacetato(2)) ligand (MOBIDA) and adenine (AdeH) of formula 1⁄2CuðMOBIDAÞðAdeHÞðH2OÞ H2O has been obtained. Its crystal structure reveals the selective formation of a rare Cu– N3(AdeH) bond, closely related to those reported by first time for compounds of general formula 1⁄2CuðBÞðAdeHÞðH2OÞ H2O, with B1⁄4N-benzylor N-(p-methy...

The structure and morphology of mixed thin films of picene (C22H14, PIC) and perfluoropentacene (C22F14, PFP) as well as mixed thin films of PIC and pentacene (C22H14, PEN) grown by simultaneous coevaporation is investigated using X-ray diffraction, atomic force microscopy, and near-edge X-ray absorption spectroscopy. For both systems we find mixing on the molecular level and the formation of m...

Single crystals consisting various surface morphologies and epitaxial structures were applied to investigate the effect of other phase regions in the vicinity of a given tethered chains-covered area having a certain molecular weight of amorphous brushes. The designed experiments demonstrated that regardless of the type of surface morphology (patterned and especial mixed-brushes, homo and co...

The reaction of single-component molecular crystal nanorods with a second species to form cocrystal nanorods is described. Single-component crystalline nanorods, composed of 9-methylanthracene (9-MA), are grown in a porous anodic aluminum oxide template. These templated rods are then exposed to a suspension of 1,2,4,5-tetracyanobenzene (TCNB) in water, which slowly diffuses into the 9-MA rods o...

Mixed films of perfluorinated pentacene and diindenoperylene are studied for their structural and optical properties on SiO2 and glass substrates. Grazing incidence Xray diffraction shows that the compounds mix on the molecular level. Two structures are identified. Their out-ofplane lattice spacing is determined by X-ray reflectivity, and their growth morphology is characterized using atomic fo...

Particle collisions are a common occurrence in the atmosphere, but no empirical observations exist to fully predict the potential effects of these collisions on air quality and climate projections. The current consensus of heterogeneous crystal nucleation pathways relevant to the atmosphere dictates that collisions with amorphous particles have no effect on the crystallization relative humidity...

This review examines how the concepts and ideas of crystallization can be extended further and applied to the field of mesoscopic soft materials. It concerns the structural characteristics vs. the macroscopic performance, and the formation mechanism of crystal networks. Although this subject can be discussed in a broad sense across the area of mesoscopic soft materials, our main focus is on sup...
