Noble-metal nanoparticles (NMNPs), with their outstanding properties, have been arousing the interest of scientists for centuries. Although our knowledge them is much more significant today, and we can obtain NMNPs in various sizes, shapes, compositions, has not waned. When talking about noble metals, gold, silver, platinum come to mind first. Still, cannot forget elements belonging so-called group, such as ruthenium, rhodium, palladium, osmium, iridium, whose physical chemical properties...
The article is about a novel material for application in optoelectronic devices: mesoporous silica the form of thin films with vertically aligned channels containing anchored propyl-copper-phosphonate functional groups.
A preliminary study of 2-amino-4-aryl-3,5-dicarbonitrile-6-thiopyridines as new potential antimicrobial drugs was performed. Special emphasis placed on the selection structure target pyridine derivatives with highest biological activity against different types Gram-stained bacteria by lipopolysaccharide (LPS). Herein, Escherichia coli model strains K12 (without LPS in its structure) and R2–R4 (with lengths were used. Studied compounds provided yields ranging from 53% to 91% lipase-catalyzed...
This study aims to thoroughly understand the local structure of copper phosphonate groups covalently attached via propyl arms pores interior SBA-15 mesoporous silica. The studied sample contains 20% propyl-POO2Cu silica matrix as host material. X-ray absorption near-edge spectroscopy (XANES) and extended fine (EXAFS) at K-edge were utilized discern valence state geometric arrangement sites within pores. Various machine learning techniques, including principal component analysis, K-means...
The paper is about a new class of antimicrobial functional nanomaterials. Proposed compounds are based on SBA-15 porous silica matrices and contain anchored copper ions. Thanks to the immobilization groups safer for environment than commonly used disinfectant agents. We prepared examined materials containing two concentrations copper-containing groups: 10 5%. For reference we samples free-standing CuO molecules in structure checked their properties. Antibacterial effect considered SBA-15-Cu...
Successful incorporation of the Mn<sub>12</sub> molecules into silica channels has been attested with AC susceptometry and magnetocaloric effect measurements.
The Mn12 single-molecule magnets (SMMs) could be attached to the surface of spherical silica for first time with a high probability. This allowed separation individual molecular and direct microscopic observation SMMs. We described in detail how fabricate such composite material. synthesis procedure proposed here is simple efficient. confirmed efficiency method by transmission electron microscopy (TEM): were visible at substrate. Based on TEM observation, we molecules anchor (the geometry...
Controlling the distribution of Mn12–stearate, single-molecule magnets (SMMs) anchored on a select surface is expected to be new method for tuning its interactions, and an investigation magnetic properties separated molecules also lacking. The anchoring SMMs at with assumed statistic distance between each other not easy task; nevertheless, in this work, we show synthesis which allows detail. immobilization Mn12–stearate was demonstrated use FTO glasses spherical silica as substrates. Based...
The magnetic behaviour of Mn 12 -stearate single-molecule magnets (SMMs) ([ O ( CH 3 2 ) 16 CO ] · COOH 4 H on the surface 300 nm spherical silica nanoparticles were investigated. SMMs bonded at with assumed number anchoring points, which influenced their degree freedom and distribution. In order to check properties molecules separated surface, interactions, samples containing four different concentration spacers per single unit variously particles prepared. materials have been examined...
