Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

Advanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...

NMR studies of solid organometallic polymers [PDF]

, 1992
A series of solid organometallic polymers is known, consisting of octahedrally coordinated M(CN)(_6) [M=Co, Fe, Ru, Os] centres linked by trigonal bipyramidal connecting rods of the form R(_3)X [R=Me, Et, Bu] and derivatives thereof.

Demonstrating Vibrational Current Generation With a Self‐Assembled Bioelectret

Advanced Functional Materials, EarlyView.
Vacuum‐deposited films of the plant‐derived molecule, Baicalein, form a self‐assembled bioelectret exhibiting spontaneous orientation polarization and a giant surface potential. The films induce alternating current during the vibration of a movable electrode without charging treatments. Hydrocarbon protection enhances the air stability of the Baicalein

Solid-state NMR on larger biomolecules [PDF]

, 2011
In the last years, remarkable progress has been made to probe molecular structure of biological systems using Magic Angle Spinning solid-state NMR (ssNMR). Prominent examples relate to research areas that have remained challenging to classical structural

Solid-state NMR on complex biomolecules: Methods and applications [PDF]

, 2018
Solid-state NMR (ssNMR) can provide structural information at the most detailed level and, at the same time, is applicable in highly heterogeneous and complex molecular environments, largely irrespective of solubility or crystallinity.

Structure and ion transport properties of organic ionic compounds revealed by NMR

Magnetic Resonance Letters
Organic ionic plastic crystals (OIPCs) are emerging as an important material family for solid-state electrolytes and many other applications. They have significant advantages over conventional electrolyte materials, such as high ionic conductivity, non ...

Structural characterization of tin in toothpaste by dynamic nuclear polarization enhanced 119Sn solid-state NMR spectroscopy

Nature Communications, 2023
Stannous fluoride (SnF2) is an effective fluoride source and antimicrobial agent that is widely used in commercial toothpaste formulations. The antimicrobial activity of SnF2 is partly attributed to the presence of Sn(II) ions. However, it is challenging

Afterglow Solid-State NMR Spectroscopy [PDF]

, 2017
Biomolecular solid-state NMR experiments have traditionally been collected through detection of 13C or 15N nuclei. Since these nuclei have relatively low sensitivity stemming from their smaller gyromagnetic ratios relative to 1H, the time required to collect multi-dimensional datasets serves as a limitation to resonance assignment and structure ...

Implantable Ionic Memristors Based on Natural Polymer Heterojunctions

Advanced Functional Materials, EarlyView.
We report an implantable natural polymer‐based ionic memristor composed of hyaluronic acid, chitosan, and PDMS. The device achieved 98.94% accuracy in MNIST classification while reducing training time by 36.8% compared with a conventional artificial neural network (ANN).

Kinetic Analysis of Protein Aggregation Monitored by Real-Time 2D Solid-State NMR Spectroscopy [PDF]

, 2011
It is shown that real-time 2D solid-state NMR can be used to obtain kinetic and structural information about the process of protein aggregation. In addition to the incorporation of kinetic information involving intermediate states, this approach can ...
