摘要： The present technology provides liquid quality assessment systems and methods for their preparation and use. The systems can include a light source configured to illuminate a liquid sample, a reflecting surface configured to reflect light scattered by the liquid sample, and a detector configured to detect light intensity, wherein the light source illuminates the liquid sample with a first incident light when the reflecting surface is absent; the detector detects a first light scattered by the liquid sample in response to the first incident light; the light source illuminates the liquid sample with a second incident light when the reflecting surface is present; and the detector detects a second light which is a combination of light scattered by the liquid sample in response to the second incident light and light reflected by the reflecting surface of light scattered by the liquid sample in response to the second incident light.

摘要： Technologies are generally described herein generally relate to tunnel field-effect transistor (TFETs) structures with a gate-on-germanium source (GoGeS) on bulk silicon substrate for sub 0.5V (VDD) operations. In some examples, the GoGeS structure may include an increase in tunneling area and, thereby, a corresponding increases in the ON-state current ION. In order to achieve supersteep sub-threshold swing, both the lateral tunneling due to gate electric-field and the non-uniform tunneling at the gate-edge due to field-induced barrier lowering (FIBL) may be suppressed through selection of component dimension in the device structure. Example devices may be fabricated using CMOS fabrication technologies with the addition of selective etching in the process flow.
摘要翻译：本文通常描述的技术通常涉及在体积硅衬底上具有用于次级0.5V（VDD）操作的栅极锗源（GoGeS）的隧道场效应晶体管（TFET）结构。在一些示例中，GoGeS结构可以包括隧道面积的增加，从而导致ON状态电流ION的相应增加。为了实现超级子阈值摆幅，可以通过选择栅极电场的横向隧穿和由场诱发的屏障降低（FIBL）在栅极边缘处的非均匀隧道效应来抑制设备结构。可以使用CMOS制造技术制造示例器件，并在工艺流程中添加选择性蚀刻。

摘要： Technologies are generally described for systems and methods for detecting chiral properties of materials and separating materials based on their chiral properties. A chiral vector is constructed from anisotropy properties of a polarization-dependent output signal from a sample. Different types of molecules from the sample can be differentiated based on a magnitude of the chiral vector. Chiral properties of the sample can be detected based on an angle of the chiral vector. The output signal can be a fluorescent emission from the sample and can be used to detect chiral properties of a substantially opaque sample.
