摘要:
Disclosed are apparatus and methods for depositing solvent-free molecules on surfaces of samples, with particular application to imaging mass spectrometry. A vacuum chamber is configured to have controllable matrix translation apparatus for controlling the position of one or more solvent-free matrices within the chamber. Sublimation apparatus is used to sublimate molecules from the solid phase matrices. One or more samples are placed separately from the solvent-free matrices within the chamber. Condensation apparatus individually cools the samples to deposit sublimated molecules on the samples. Controllable sample translation apparatus is used to control the position of the samples within the chamber. Rotatable sample holding apparatus may be used to hold and move the samples to allow deposition of molecules on multiple samples at substantially the same time. Rotatable matrix holding apparatus may also be used to hold and move a plurality of matrices to create a homogenous mixture of molecules that are deposited onto one or more samples. As surface characterization system may be used to monitor deposition of the molecules to determine their thickness and roughness. A computer may be configured to control the matrix translation apparatus, the sublimation apparatus, the condensation apparatus, and the sample translation apparatus to provide for automated deposition of solvent-free molecules on the samples.

摘要:
A bulk container is formed from a blank of corrugated sheet material having wall fold lines demarcating end wall panels and side wall panels, and flap fold lines demarcating top and bottom closure flaps. A T-shaped slot in the blank separates adjacent closure flaps from one another. A first portion of each slot extends inwardly from the free outer edges of the closure flaps and terminates at a second portion which extends substantially perpendicular to the first portion. The first portion of each slot is substantially aligned with a corresponding wall fold line. The second portion of each slot extends substantially colinearly with a flap fold line. The slots reduce binding and bunching of the thick multilayer reinforced walls found in conventional bulk container constructions, and at the same time avoid formation of through-holes at the corners of the container.
摘要:
A method and apparatus for measuring characteristics of a piece of material, typically semiconductor materials including photovoltaic devices. The characteristics may include dislocation defect density, grain boundaries, reflectance, external LBIC, internal LBIC, and minority carrier diffusion length. The apparatus includes a light source, an integrating sphere, and a detector communicating with a computer. The measurement or calculation of the characteristics is calibrated to provide accurate, absolute values. The calibration is performed by substituting a standard sample for the piece of material, the sample having a known quantity of one or more of the relevant characteristics. The quantity measured by the system of the relevant characteristic is compared to the known quantity and a calibration constant is created thereby.
摘要:
The present invention provides methods of attenuating or preventing brain injury mediated damage in the central nervous system by attenuating or preventing leukotriene-mediated events following a brain injury or long-term neuroinflammation after brain injury, in Alzheimer's disease, multiple sclerosis, stroke, and post-traumatic stress disorder. The methods comprise administering at least one 5-lipoxygenase activating protein (FLAP) inhibitor either before or after the brain injury. The method finds use in the treatment of traumatic brain injury (TBI), stroke, multiple sclerosis, Alzheimer's disease, post-traumatic stress disorder and other brain injuries associated with production of leukotrienes in the central nervous system. Preferably the FLAP inhibitor is administered intranasally and preferably for certain high risk individuals prophylactically prior to any potential brain injury event.
