  • The chemical sensor plays an essential role in the fields of environmental conservation and monitoring, disaster and disease prevention, and industrial analysis. A typical chemical sensor is a device that transforms chemical information in a selective and reversible way, ranging from the concentration of a specific sample component to total composition analysis, into an analytically useful signal.

  • The hole closing reported in this letter is certainly not caused by deposition of carbon-rich material by the electron beam, a common phenomenon in electron microscopy. The observation that large pores expand is in direct contradiction with potential contamination growth. Secondly, electron-energy-loss spectra (EELS) locally obtained on the material that filled a nanopore clearly show the presence of silicon and oxygen,but the absence of any carbon (detection limit was less than 2%).

  • Although there is a variety of commercially available solid-state sensors, a little-known option is using a common silicon diode like the Fairchild Semiconductor 1N914. They are small and quite rugged as sensors go. And, since they cost only pennies apiece, they are definitely the cheapest option. We’re all aware that a common silicon diode has about a 0.5-V junction potential at room temperature.

  • "Trái tim" của tất cả các máy ảnh kĩ thuật số là một chip silicon nhạy cảm với ánh sáng được gọi là bộ cảm biến (sensor). Cảm biến là nơi có chức năng ghi lại hình ảnh đối tượng muốn chụp. Kích cỡ của những chip này có hình chữ nhật, thay đổi tùy thuộc loại máy ảnh. Trong máy ảnh compact, cảm biến này tương đối nhỏ, đôi khi không lớn hơn so với kích thước của móng tay út.
