摘要:
Adsorption of molecules onto a thin metallic surface such as of gold, silver or copper is measured by surface plasmon resonance (SPR) using Fourier Transform (FT) spectroscopy. Reflectance spectra from a prism/metallic film sample surface at a fixed angle of incidence is measured with FT spectroscopy. The reflectance spectrum exhibits a pronounced minimum due to the SPR effect, which can be shifted by changing the angle of incidence or metallic film thickness. The position of the reflectance minimum shifts in wavelength with the adsorption of molecules onto the gold surface due to a change in the index of refraction at the interface. The FT-SPR sensor instrument provides wavelength stability and reproducibility of the resonance wavelength to permit detection of small wavelength shifts, and also substantially increases the spectral range over which the SPR measurements can be made. A beam of broadband radiation from a Michelson interferometer is directed through an SPR sample cell and onto a detector where the output signal is processed using standard FT techniques.
摘要:
A panel assembly for a vehicle and a method of supporting the panel assembly is disclosed. The panel assembly includes a first wall and a bracket adjacent to the first wall. The bracket has a first platform facing the first wall. The panel assembly further includes a first support member attached to the first platform and defining an initial state and a final state. The first support member and the first wall define a first gap therebetween when in the initial state. The first support member is expandable to contact the first wall to remove the first gap when in the final state for supporting the first wall to prevent deformation of the first wall.

An improved spa control system is disclosed. The invention describes a spa control system which calculates the time required to heat the water in the spa system to a desired temperature. From that information, the heating rate of the spa system can be determined, and the heating element of the spa system can be activated at the proper time to raise the temperature of the water to a selected temperature by a desired time. The spa system also monitors information which might show errors in the operation of the spa system such as a blockage in the flow of water over the heating element in the spa system.

摘要:
A breathing exercise device is formed of a tubular body with a mouthpiece at its proximal end, a resistor sleeve coaxial with the body tube and having a number of resistance openings which align with a body tube opening, and a selective one way flap valve assembly disposed at the distal end of the body tube. The flap valve assembly can be rotated 180 degrees to change the mode of the breathing exercise device from inhalation to exhalation thereapy, or vice versa.
摘要:
A novel catalyst comprises (i) an organophosphorus-containing compound, (ii) a compound, which is reactable in the Michael reaction, and contains both (a) a double or triple bond and (b) an electron withdrawing group and (iii) an alcohol or a mixture of an alcohol and a solvent. The novel catalyst may be generated from a novel catalyst precursor. The catalyst may be used to transesterify carboxylic or carbonic acid esters, to produce formate esters from alcohols and carbon monoxide and to produce formamides from amines and carbon monoxide.
摘要:
A process for the transesterification of a carboxylic or carbonic acid ester comprises reacting the carboxylic or carbonic acid ester under transesterification conditions with an alcohol in the presence, as catalyst, of either (i) a Group V element-containing Lewis base and an epoxide or (ii) a cyclic amidine.The Lewis base can be an organic compound containing trivalent phosphorus or nitrogen and can be an amine, for example an amidine.The process can be operated in the liquid phase at a temperature of from 15.degree. to 150.degree. C., and the catalyst is employed in solution.Preferred catalysts are those where the cyclic amidine forms part of a fused ring system containing six and five membered rings, six and seven membered rings or two six membered rings.
