Handles (linkers) with an aldehyde functionality that permits the anchoring of substrates by reductive amination have, since their first report in the mid-1990s, become widely-used tools in solid-phase synthesis. In the synthesis of peptides, they allow anchoring of the growing peptide chain through a backbone amide, thus giving easy access to C-terminal modified or cyclic peptides. Recently, w...

This study presents the year-round variability of water-soluble fraction trace elements (wsTE) and rare earth (wsREE) among size segregated airborne particulate matter samples collected at Ny-Ålesund in Svalbard Archipelago from 26 February 2018 to 2019. Six different aerosol dimensional fractions were using a multi-stage Andersen impactor better understand local global circulation with aim dis...

Gold nanoparticles (Au NPs) were almost chosen as the first option for biological and biosensor applications due to their enhancement outstanding properties. The combining of optical fiber with localized surface plasmon resonance (LSPR) forming a is widely used in diagnosis. In this work, we report based on LSPR Au NPs detection bovine serum albumin (BSA) protein. BSA was functionalized immobil...

Definition The concept of a metropolitan areas is that of a core area containing a large population nucleus, together with adjacent communities having a high degree of economic and social integration with that core. They include metropolitan statistical areas (MSA’s), consolidated metropolitan statistical areas (CMSA’s), and primary metropolitan statistical areas (PMSA’s). An area that qualifie...
