Construction of a Liquid-State NMR DNP Shuttle Spectrometer: First Experimental Results and Evaluation of Optimal Performance Characteristics

open access: yes, 2008
.First results from a liquid-state shuttle dynamic nuclear polarization (DNP) spectrometer are presented. The device polarizes a water sample at 9.7 GHz and 0.34 T in a commercial Bruker electron paramagnetic resonance (EPR) spectrometer and then ...

Ionic‐Electronic Hydrogel‐Liquid Metal Composite Bilayer with Tissue‐Adaptive and Adhesive Properties for Closed‐Loop Neuroprosthetic System

open access: yesAdvanced Functional Materials, EarlyView.
A hydrogel–liquid metal composite peripheral nerve interface (HLB‐PNI) combines electrically durable electrodes and tissue‐adhesive hydrogel for tissue‐adaptive implantation. In nerve‐injured rats, it enables the diagnosis of sensory‐motor connectivity via stimulation and neural signal recording.

Intrabandgap States Engineering in Functionalized Nanodiamond to Generate Solvated Electrons for Photocatalysis Under Solar Illumination

open access: yesAdvanced Functional Materials, EarlyView.
The negative electron affinity of diamond allows to emit highly reductive electrons. By introducing intra‐bandgap states and an optimized electron transfer mechanism by surface functionalization with Ru(bpy)3, the formation of solvated electrons is achieved upon solar irradiation.

Switchable Supramolecular Adhesive by Tuning Interfacial Bonding and Modulus

open access: yesAdvanced Functional Materials, EarlyView.
The supramolecular adhesive (HyDiP) shows reversible adhesion and recyclability. In the dehydrated state, it is dense, stiff (E ≈445 MPa), transparent, and provides strong bonding with adhesion strengths up to 4.65 MPa. In the hydrated state, it becomes porous, soft (E ≈0.11 MPa), and detaches easily, enabling sustainable high‐strength applications ...

Bounds on the entanglability of thermal states in liquid-state nuclear magnetic resonance

open access: yes, 2004
The role of mixed state entanglement in liquid-state nuclear magnetic resonance (NMR) quantum computation is not yet well-understood. In particular, despite the success of quantum information processing with NMR, recent work has shown that quantum states

Controlling 3D Contractility via Engineered Fibrous Hydrogel Composites

open access: yesAdvanced Functional Materials, EarlyView.
A tunable composite contractile assembly (CCA) is developed that can permit or resist contraction without changing cell‐adhesion and density, unlike collagen whose inherent coupling of these ECM cues limits its use as a platform in contractility studies.

A Programmable Semiconductor Containing Active Molecular Photoswitches Located in the Crystal's Volume Phase

open access: yesAdvanced Functional Materials, EarlyView.
A novel approach for the design of functional semiconductors is presented, which utilizes the excellent optoelectronic properties of layered hybrid perovskites and the possibility to introduce a molecular photoswitch as the organic spacer. This concept is successfully demonstrated on a coumarin‐based system with the possibility to change the bandgap ...
