摘要:
A process for making an first material/second material nanocomposite is disclosed. The process can include providing a precursor that contains an electrochemically active and an electrochemically inactive material. Thereafter, the precursor can be suspended in an aerosol gas to produce an aerosol and a plasma having a high field zone can be provided. The aerosol can be passed through the high field zone of the plasma and result in the vaporization of at least part of the precursor in the aerosol. The precursor that has been vaporized in the high field zone is subsequently removed therefrom and allowed to condense into an first material/second material nanocomposite with at least one electrochemically active material.

Disclosed is a process for making a composite material that contains structured particles. The process includes providing a first precursor in the form of a dry precursor powder, a precursor liquid, a precursor vapor of a liquid and/or a precursor gas. The process also includes providing a plasma that has a high field zone and passing the first precursor through the high field zone of the plasma. As the first precursor passes through the high field zone of the plasma, at least part of the first precursor is decomposed. An aerosol having a second precursor is provided downstream of the high field zone of the plasma and the decomposed first material is allowed to condense onto the second precursor to from structured particles.
摘要:
A system and method for dynamic modification and generation of data. One embodiment includes an annotation server that is connected to a user and a content provider. The annotation server is configured to modify a copy of an enterprise's stored Web content without necessarily modifying the actual stored Web content. The annotation server then provides the modified content to the user for viewing or other use.

The present invention provides methods for modulating cellulose, hemicellulose and lignin composition and deposition in secondary cell wall layers of plants to improve plant traits that are commercially desirable (e.g., enhanced digestibility of forage crops by animals, increased post-harvest processing of wood and crops for energy production and pulping, increase mechanical strength of plants, and others). The invention also provides methods for identifying genes encoding transcription factors that regulate the formation of secondary cell walls, polynucleotide sequences that encode key components of secondary cell walls, and transgenic plants comprising these sequences.

An intramedullary nail (20) and related method for fixing a fracture in a long bone. The nail (20) comprises an elongate member (22) having a longitudinal axis (54), a proximal end section (32), a distal end section (34) and a solid central section (24) extending between the proximal and distal end sections (32, 34). The proximal and distal end sections (32, 34) respectively include proximal and distal fastener receiving areas (28, 30) of greater cross sectional dimensions than the central section (24). Each fastener receiving area (28, 30) includes at least one hole (50, 52) extending transverse to the longitudinal axis for receiving a cross fastener (110) adapted to secure to the bone on opposite sides of the elongate member (22). The proximal and distal end sections (32, 34) thereby provide rigid anchoring locations relative to the central section (24) and the central section provides flexibility to promote healing of the fracture.

Liquid crystal compounds have been synthesized of general formula (I) and may be mixed with other liquid crystal compounds to give useful liquid crystal mixtures which may then be used in liquid crystal devices. Such devices include linear and non-linear electrical, optical and electro-optical devices, magneto-optical devices and devices providing responses to stimuli such as temperature changes and total or partial pressure changes. Formula (I) where each Z.sub.1-6 is given by formula (II), where Y for each of Z.sub.1-6 is independently COO, OCO, CH.sub.2 O and OCH.sub.2, m defines the number of substituents on each of Z.sub.1-6 and is independently 0-5,and X is independently for each substituent on each of Z.sub.1-6 alkyl (straight chain, branched and chiral), alkoxy (straight chain, branched or chiral), alkanoyl (straight chain, branched or chiral), alkenyl (straight chain, branched or chiral), halogen, halogenoalkyl (straight chain, branched or chiral) and CN, provided that at least one of Z.sub.-6 1 has at least one substituent X, and excluding where m is 1 for each of Z.sub.1-6, Y is COO for each of Z.sub.1-6 and X is n-alkyl or n-alkoxy positioned para to Y for each of Z.sub.1-6 and also where M is 5 for each of Z.sub.1-6, Y is COO for each of Z.sub.1-6 and for each Z.sub.1-6 X is selected as n-alkoxy positioned para to Y and fluoride for all other substituents.
