Abstract: A method of estimating a radiation dose deposited on a radiochromic film based on absorption measurements at least at two wavelengths as well as devices implementing the estimation method. The method includes the following steps: (a) measuring absorption values at a first wavelength and a second wavelength; (b) converting the absorption values at the two wavelengths to dose values at the corresponding wavelengths by using a calibration procedure; (c) obtaining a weighting factor curve (weighting factor vs. dose) at each wavelengths; and (d) obtaining an estimate of irradiation dose at the location on the radiochromic film by minimizing the objective function which takes the weighting factors and the dose values at both wavelengths as input.

Abstract: A method for fabricating scanning probe microscopy (SPM) probes is disclosed. The probes are fabricated by forming a structural layer on a substrate, wherein the substrate forms a cavity. A sacrificial layer is located between the substrate and the structural layer. Upon forming the structural layer, the sacrificial layer is selectively removed, and the probe is then released from the substrate. The substrate may then later be reused to form additional probes. Additionally, a contact printing method using a scanning probe microscopy probe is also disclosed.

Abstract: A method of forming a phosphosilicate glass, includes flowing a pre-deposition gas comprising an inert gas into a deposition chamber containing a substrate, where the temperature of the substrate is at a pre-deposition temperature of at least 400° C; continuously increasing the temperature of gas in the chamber to a deposition temperature and simultaneously continuously increasing a flow rate of phosphine and silane until a phosphine:silane deposition ratio is achieved; and depositing the phosphosilicate glass on the substrate at the deposition temperature and at the phosphine:silane deposition ratio.
Abstract: A composition comprises a protein, a polyol, and a metal. The protein is stabilized by the polyol and the metal, and is protected from denaturing when in contact with an organic solvent. The polyol may be a hydrocarbon containing two or more hydroxyl groups (—OH) bonded to carbon. The metal may be divalent.

Abstract: A transmissible spongiform encephalopathy (TSE) agent is inactivated by exposing the TSE agent to a thermostable proteolytic enzyme at elevated temperature and at acid or alkaline pH. Following this step, or separately, presence of TSE infectivity is detected by detection of dimers of prion protein.

Abstract: A probe array for includes a handle, a first probe and a second probe. The first probe has a first shank, connected to the handle, and a first tip; and the second probe has a second shank, connected to the handle, and second tip. The first tip contains a different material from the second tip. The probe array may be used to write on a surface by contacting the first tip with a surface, where a first ink is on the first tip. This writing method may further include lifting the first tip from the surface and contacting the second tip with the surface.

Abstract: The activity of multiple proteins in a single living cell, portion of a cell or in a group of cells is simultaneously measured by introducing reporter molecules into the cell(s) or a portion thereof, chemically modifying the reporter(s) by the enzyme of interest, terminating the modification reactions, removing the reporter(s) and modified reporter(s), and determining the amount of enzyme activity present by measuring or comparing the amount of reporter(s) and modified reporter(s) present. By performing a series of experiments at different time points, conditions, and varieties of cell types, a database is developed for molecular cellular mechanisms in health and disease states. By exposing cells to a variety of compounds data for drug development and screening is provided.
