However' selecting an appropriate Poincaré plane is a crucial part of extracting best Poincaré samples. There is no unique way to choose a Poincaré plane' because it is highly ...

Label-free NMR-based dissociation kinetics determination.

Understanding the dissociation of molecules is the basis to modulate interactions of biomedical interest. Optimizing drugs for dissociation rates is found to be important for their efficacy, selectivity, and safety. Here, we show an application of the high-power relaxation dispersion (RD) method to the determination of the dissociation rates of weak binding ligands from receptors. The experiment probes proton RD on the ligand and, therefore, avoids the need for any isotopic labeling. The large ligand excess...

Emergence of Veterinary Parasitology in the United States: Maurice C. Hall and the Bureau of Animal Industry.

By 1883 a Veterinary Division had been established within the United States Department of Agriculture, itself established in 1862. Federal concern about animal health in the U.S.A. emerged as early as 1865 when Congress adopted regulations aimed at controlling importation of livestock. It was not until 1884 that the Bureau of Animal Industry (BAI) was formally created by Act of Congress, and shortly after that the Zoological Laboratory was established and assigned responsibility for study of parasites and t...

Area-controllable Stamping of Semicrystalline Copolymer Ionogels for Solid-state Electrolyte-gated Transistors and Light-emitting Devices.

Two types of thin-film electrochemical devices (electrolyte-gated transistors and electrochemical light-emitting cells) are demonstrated by using area-controllable ionogel patches generated by transfer stamping. For the successful transfer of ionogel patches on various target substrates thermoreversible gelation by phase-separated polymer crystals within the ionogel is essential because it allows the gel to form a conformal contact with the acceptor substrate, and thereby lowering the overall Gibbs energy o...

Structural emergence in particle dispersions.

Particle dispersions, such as pigment-based inks, comprise weakly bound, milled nanoparticles. The properties of these pigments depend on both their chemical composition, as well as a rather complex structural hierarchy, which emerges from these dispersions. The emergence of structure under semi-dilute conditions is related to the structure of the dilute particles, the particle spacing (mesh size), processing history, and the interaction potential. Kinetic simulations could predict such emergence using thes...
