摘要:
Systems and methods for enhancing spectral domain optical coherence tomography (OCT] are provided. In particular, a system and method for calibration of spectral interference signals using an acquired calibration signal are provided. The calibration signal may be logarithmically amplified to further improve the accuracy of the calibration. From the calibration signal, a series of more accurate calibration data are calculated. An acquired spectral interference signal is calibrated using these calibration data. Moreover, systems that include logarithmic amplification of the spectral interference signal and variable band-pass filtering of the spectral interference signal are provided. Such systems increase the dynamic range and visualization capabilities relative to conventional spectral domain OCT systems.

This disclosure provides systems, methods, and apparatus related to solar water splitting. In one aspect, a structure includes a plurality of first nanowires, the plurality of first nanowires comprising an n-type semiconductor or a p-type semiconductor. The structure further includes a second nanowire, the second nanowire comprising the n-type semiconductor or the p-type semiconductor, the second nanowire being a different composition than the plurality of first nanowires. The second nanowire includes a first region and a second region, with the first region having a conductive layer disposed thereon, and each of the plurality of first nanowires being disposed on the conductive layer.
摘要:
Flavonoid compounds that are selective for a protein, a portion or a living cell, or a portion of an organism may be used as biological imaging agents. The flavonoid compounds are useful for methods of imaging organisms such as zebrafish embryos and zebra fish. Flavonoid compounds may also be used to detect protein. Advantageously, flavonoids that selectively bind protein, a portion of a living cell, or a portion of an organism may exhibit a florescence “turn-on” mechanism, where the flavonoids that are selectively bound exhibit a florescence response when excited.

A mercury-free lead-free button battery includes a negative cap, a cathode material, a gasket ring, a positive can, an anode material, and a diaphragm. The positive can and the negative cap are combined. The gasket ring is clamped between the positive can and the negative cap for separating the positive can from the negative cap. The cathode material is arranged on the bottom of the positive can. The diaphragm is arranged on the cathode material. The anode material is arranged between the negative cap and the diaphragm. A partition unit is arranged between the negative cap and the anode material for separating the anode material from the negative cap and conductively connecting the anode material and the negative cap. The partition unit ensures disconnection between the anode material and the negative cap and therefore safety of the battery by preventing expansion, weeping and even that would otherwise happen.
