Abstract:
A porous metal-oxide composite particle suitable for use as a oxygen reduction reaction or oxygen evolution reaction catalyst and sacrificial support based methods for making the same.
Abstract:
A heterogeneous scintillator material is provided comprising core/shell nanoparticles having a highly hygroscopic or deliquescent halide-based core activated with trivalent Ln3+ or divalent Ln2+ lanthanide ions (Ln=La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) and a stable non-hygroscopic shell thereon. The heterogeneous nanoparticles can comprise highly hygroscopic lanthanide halide (LaBr3, LuI3) cores protected with stable non-hygroscopic LaF3 shells. The heterogeneous nanoparticles can comprise deliquescent alkaline earth halide (SrI2, BaI2) cores protected with stable non-hygroscopic (SrF2, BaF2) shells.
Abstract:
In one embodiment, the invention provides a new design of nanocarrier compositions that release their therapeutic load specifically at intraperitoneal cancers' site. These nanocarriers are administered intraperitoneally and comprise a plurality of porous nanoparticulates that (a) are loaded with one or more pharmaceutically-active agents alone or in combination with imaging agents thus providing a theranostic value and (b) that are encapsulated by and that support a lipid bilayer which is disrupted upon contact with a reactive oxygen species generated within the environment of the cancer. In other embodiments, the invention provides methods of treatment and pharmaceutical compositions comprising nanocarriers as described herein.
Abstract:
A method of preparing M-N—C catalysts utilizing a sacrificial support approach and inexpensive and readily available polymer precursors as the source of nitrogen and carbon is disclosed. Exemplary polymer precursors include those that do not form complexes with iron, but which do complex with silica, for example, polyetheleneimine (PEI), Poly(2-ethyl-2-oxazoline), Poly(acrylamide-co-diallyldimethylammonium chloride), Poly(melamine-co-formaldehyde), Poly[[6-[(1,1,3,3-tetramethylbutyl)amino]-s-triazine-2,4-diyl]-[(2,2,6,6-tetramethyl-4-piperidyl)imino]-hexamethylene-[(2,2,6,6-tetramethyl-4-piperidyl)imino] and the like.
Abstract:
This disclosure describes a structured polynucleotide, devices that include the structured polynucleotide, and methods involving the structured polynucleotide and/or devices. Generally, the structured polynucleotide includes five domains. A first domain acts as a toehold for an input DNA logic gate to initiate binding to an SCS biomolecule. A second domain acts as a substrate recognition sequence for an upstream DNA logic gate. A third domain acts as a toehold for a output DNA logic gate to initiate binding of the SCS biomolecule to the gate. A fourth domain acts as an effector sequence to alter the state of the output logic gate. A fifth domain acts as a cage sequence to lock the effector sequence in an inactive state until an input gate binds to the structured polynucleotide.
Abstract:
Apparatus and methods comprise examination of a subject using images of the subject. The images can provide a non-invasive analysis technique and can include a plurality of images of a portion of the subject at different times a temperature stimulus applied to the subject. An image of the portion of the subject can be aligned such that each pixel of the image corresponds to the same point on the subject over a sequence of images of the portion. The sequence of images can be processed after aligning the images such that data is extracted from the images. The extracted data can be used to make decisions regarding the health status of the subject. Additional apparatus, systems, and methods are disclosed.
Abstract:
The invention is a multi-purpose system and methods that focuses on the prevention of congestive heart failure (CHF) exacerbations by identifying the population at risk, examining their use of medications that optimize ventricular function, tracking weight changes through different phases of illness, and retrieving vital sign and laboratory data needed for treatment intensification.
Abstract:
A variety of polymers and copolymers suitable for use as biologically compatible constructs and, as a non-limiting specific example, in the formation of degradable tissue scaffolds as well methods for synthesizing these polymers and copolymers are described. The polymers and copolymers have degradation rates that are substantially faster than those of previously described polymers suitable for the same uses. Copolymers having a synthesis route which enables one to fine tune the degradation rate by selecting the specific stoichiometry of the monomers in the resulting copolymer are also described. The disclosure also provides a novel synthesis route for maleoyl chloride which yields monomers suitable for use in the copolymer synthesis methods described herein.
Abstract:
Scalable, hierarchically structure biopolymer carbon architectures that are suitable for use as bioelectrodes and biologically friendly methods for making the same.
