In-situ polymerized Pebax®/polydopamine blend membranes with high CO2/N2 selectivity [PDF]

open access: yesPolímeros
The objective of this work was to produce Pebax®/polydopamine (PDA) blends and apply these blends to produce membranes for gas separation. Flat sheet membranes were tested for gas permeation, differential scanning calorimetry (DSC), thermal gravimetric ...

Synthesis of Aminoglycoside-2′-O-Methyl Oligoribonucleotide Fusions

open access: yesMolecules, 2017
Phosphoramidite building blocks of ribostamycin (3 and 4), that may be incorporated at any position of the oligonucleotide sequence, were synthesized. The building blocks, together with a previously described neomycin-modified solid support, were applied

Melting behavior of polymorphic MDI/BD-block TPU investigated by using in-situ SAXS/WAXS and FTIR techniques. Hydrogen bonding formation causing the inhomogeneous melt

open access: yesPolymer Testing, 2021
MDI/BD hard segment based TPUs exhibit two distinct polymorphs, form I and form II, when it is solution-cast at 60 and 145 °C. Form I shows paracrystalline features, whereas form II typically shows semi-crystalline spherulitic structures with ...

On the Multiscale Oceanic Heat Transports Toward the Bases of the Antarctic Ice Shelves

open access: yesOcean-Land-Atmosphere Research, 2023
The mass balance of the Antarctic Ice Sheet (AIS) is important to global sea-level change. The AIS loses mass mainly through basal melting and subsequent calving of the Antarctic ice shelves.

Synthesis and Excellent Duplex Stability of Oligonucleotides Containing 2′-Amino-LNA Functionalized with Galactose Units

open access: yesMolecules, 2017
A convenient method for the preparation of oligonucleotides containing internally-attached galactose and triantennary galactose units has been developed based on click chemistry between 2′-N-alkyne 2′-amino-LNA nucleosides and azido-functionalized ...

Binary hard sphere mixtures in block copolymer melts [PDF]

open access: yesPhysical Review E, 2002
We perform a self-consistent-field/density-functional-theory hybrid analysis for a system of diblock copolymers mixed with polydisperse, hard, spherical particles of various chemical species. We apply this theory to study the equilibrium morphologies of two different binary sphere/diblock melts.
