Study of Hydrophobic Domains in Humic Acids [PDF]

open access: yes, 2008
Fyzikálně-chemická povaha hydrofobních domén huminových kyselin byla studována z několika hledisek. K objasnění významu fluorescenčních spekter byly vzorky podrobeny sekvenční frakcionaci, která pomohla k částečnému objasnění vlivu vodorozpustných složek,

Nuclear magnetic resonance measurements reveal the origin of the Debye process in monohydroxy alcohols

open access: yes, 2010
Monohydroxy alcohols show a structural relaxation and at longer time scales a Debye-type dielectric peak. From spin-lattice relaxation experiments using different nuclear probes an intermediate, slower-than-structural dynamics is identified for n-butanol.

Living Liquid Metal Composites Embedded with Electrogenic Endospores for Next‐Generation Bioelectronics

open access: yesAdvanced Functional Materials, EarlyView.
A new class of living liquid metal composites is introduced, embedding Bacillus subtilis endospores into eutectic gallium–indium (EGaIn). The spores enhance droplet coalescence, strengthen interfacial conductivity, and provide on‐demand electrogenic functionality after germination. The composites exhibit high conductivity, self‐healing, patternability,

One-shot preparation of topologically chimeric nanofibers via a gradient supramolecular copolymerization

open access: yesNature Communications, 2019
Supramolecular polymers can form highly accessible polymeric nanomaterials. Here the authors report the facile preparation of supramolecular copolymers involving segregated secondary structures by cooling non-polar solutions containing two monomers that ...

Bioengineered Textiles and Nonwovens – the convergence of bio-miniaturisation and electroactive conductive polymers for assistive healthcare, portable power and design-led wearable technology [PDF]

open access: yes, 2009
Today, there is an opportunity to bring together creative design activities to exploit the responsive and adaptive ‘smart’ materials that are a result of rapid development in electro, photo active polymers or OFEDs (organic thin film electronic devices),

Polyferrocene‐Based Cubosomes: Conversion to Magnetic Mesoporous Microparticles, Supramolecular Modification, and Oxidation Response

open access: yesAdvanced Functional Materials, EarlyView.
Polyferrocene block copolymers are synthesized and assembled into micron‐sized polymer cubosomes with double diamond lattice and pore diameter of ≈30 nm. The ferrocene functionality is retained within the polymer cubosome wall as demonstrated on supramolecular modification, and oxidative disassembly.

Supramolecular polymers

open access: yesMateriali in tehnologije, 2003
In this work supramolecular polymerization and polymers are reviewed. The concepts behind supramolecular chemistry underlie molecular recognition based on the bonding of complementary functional groups of low molar mass compounds or polymers via noncovalent interactions (Coulombic interactions, hydrogen bonding, and van der Waals interactions).

Bio‐Orthogonally Crosslinked Supramolecular Polymer Bottlebrush Hydrogels for Long‐Term 3D Cell Culture

open access: yesAdvanced Functional Materials, EarlyView.
Fibrous benzenetrispeptide (BTP) hydrogels, fabricated via strain‐promoted azide‐alkyne cycloaddition (SPAAC) crosslinking, form robust, bioinert networks. These hydrogels can support 3D cell culture, where cell viability and colony growth depend on the fiber content.
