Fractional calculus and continuous-time finance II: the waiting-time distribution

open access: yes, 2000
We complement the theory of tick-by-tick dynamics of financial markets based on a Continuous-Time Random Walk (CTRW) model recently proposed by Scalas et al., and we point out its consistency with the behaviour observed in the waiting-time distribution ...

Toward Personalized Stationary Chromatography Phases: Equipping Commercial Silica Phases with Selected Peptide‐Based Binding Domains to Tailor Affinity

open access: yesAdvanced Materials Interfaces, EarlyView.
The 7‐mer peptide motifs QFFLFFQ, QFFEFFQ, and QFQQSFF, known as good, medium, and poor binders for the photosensitizers m‐THPC and Chlorin E6 are covalently immobilized on commercial amino‐functionalized silica particles by inverse electron‐demand Diels‐Alder ligation.

Aqueous Synthesis of Poly(ethylene glycol)‐Amide‐Norbornene‐Carboxylate for Modular Hydrogel Crosslinking

open access: yesAdvanced Materials Interfaces, EarlyView.
An all aqueous synthesis of poly(ethylene glycol)‐amide‐norbornene‐carboxylate (PEGaNBCA) is developed via reacting carbic anhydride with amino‐terminated PEG. PEGaNBCA is readily crosslinked into hydrogels by click chemistries. PEGaNBCA crosslinked thiol‐norbornene hydrogels are hydrolytically stable but can be rendered hydrolytically labile through ...

Spatially Controlled 3‐D Multiplexed Aptamer Patterning in Hydrogels

open access: yesAdvanced Materials Interfaces, EarlyView.
A hydrogel platform based on norbornene‐functionalized polyvinyl alcohol enables high‐resolution, 3‐D multiplexed patterning of DNA aptamers via two‐photon polymerization. Two distinct aptamers are covalently immobilized with single micron‐scale precision across the x, y, and z dimensions.

Antifouling PEG Coatings by Thiol‐Acrylate Conjugate Addition Reactions for Generation of Protein Patterns via Photobleaching‐Induced Protein Binding (PiPB) BioBitmaps Using Maskless Projection Lithography

open access: yesAdvanced Materials Interfaces, EarlyView.
Homo‐bifunctional PEG, acrylate‐PEG‐acrylate (PEGDA), coatings are prepared on glass and glass‐type surfaces using solvent‐free thiol‐acrylate conjugate addition reactions at room temperature. The prepared PEGDA coatings are stable, antifouling, and provide feature terminal acrylates that can act as free radical acceptors for photobleaching‐induced ...

Surface Coordination and Polymerization of Allyl Mercaptan Passivates the Oxidation of Copper

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates that allyl mercaptan self‐assembles on the surface of copper via coordination and polymerization, forming an ultrathin polymeric passivation layer (8.06 ± 0.50 nm). The modified copper foil achieves a two‐order‐of‐magnitude anti‐corrosion performance enhancement across multi‐service environments. Abstract The oxidation of copper
