Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

Low‐Temperature Reverse Water–Gas Shift Enabled by Magnetically Induced Catalysis

open access: yesAngewandte Chemie, EarlyView.
Magnetically induced catalysis using standard Cu–Al spinel‐derived catalyst functionalized with carbon‐coated iron nanoparticles enables high CO yield (up to 62%) at mild catalyst and reactor temperatures (estimated at 300°C and determined as 25–123°C, respectively).

Optimizing the process of supercritical extraction of lemon balm (Melissa Officinalis L.) [PDF]

open access: yes, 2010
This work investigates the process of extraction of lemon balm (Melissa officinalis L.) by treatment with carbon dioxide at supercritical conditions. The process kinetics is studied at different operational conditions, and the influence of some important

Fluorescent Polymeric Nanofibers as Ratiometric Multiplexed Skin Sensors of pH and Oxygen

open access: yesAdvanced Healthcare Materials, EarlyView.
Fluorescent polymeric nanofibers and nanorods are produced as ratiometric sensors of two important physiological parameters: pH and oxygen. They operate by dual Forster resonance energy transfer from large number of energy donor dyes to limited number of two distinct energy acceptors, enabling simultaneous sensing of pH and oxygen.

Coupling between membrane tilt-difference and dilation: a new ``ripple'' instability and multiple crystalline inclusions phases [PDF]

open access: yes, 1998
A continuum Landau theory for the micro-elasticity of membranes is discussed, which incorporates a coupling between the bilayer thickness variation and the difference in the two monolayers' tilts. This coupling stabilizes a new phase with a rippled micro-

Increased Anti‐Psoriatic Effect of Anti‐Inflammatory Dendrimers Using Fluid Catanionic Vesicle‐Based Topical Formulations

open access: yesAdvanced Healthcare Materials, EarlyView.
Next‐Generation Psoriasis Therapy – With advanced dendrimer‐based formulations, this study paves the way for highly effective, skin‐permeable treatments. Encapsulated in fluid catanionic vesicles, IMD‐006 and its analogues show promising anti‐psoriatic effects offering a targeted, non‐invasive approach to managing chronic skin inflammation.

Nitroxide‐Mediated Photo‐Polymerization: A Swiss Army Knife for Microfluidic Design

open access: yesAdvanced Materials Technologies, EarlyView.
This article illustrates the application of NMP2 to the rapid (less than 1 h) photostructuring and sealing of model structures intended for microfluidic applications. Remarkably, the careful design of resin composition allows completing these steps by simply spreading bare monomer (i.e., no added photoinitiator) on top of the bottom layer embedding ...

Pulling and Stretching a Molecular Wire to Tune its Conductance

open access: yes, 2015
A scanning tunnelling microscope is used to pull a polythiophene wire from a Au(111) surface while measuring the current traversing the junction. Abrupt current increases measured during the lifting procedure are associated to the detachment of molecular
