Abstract Conventional photopolymerization-based 3D printing still requires developing a concise and cost-effective method to improve the resolution at nanoscale. Here, we propose use of gaming console optical drive pickup unit for photopolymerization. This mass-produced features finely adjustable diode laser, allowing us adjust from tens micrometres down hundreds nanometres without requiring ox...

Due to the high sensitivity, nearly linear response, and easy availability, we will use a 1N4148 diode for the temperature transducer in our measurements. The current conducted through an ideal diode is described by the Shockley ideal diode equation: I D = I S exp q V D n k B T − 1 where q is the electron charge, k B is Boltzmann's constant, T is the temperature of the diode junction, and V D i...

An analysis of tnmel-diode low-level detection is presented for the purpose of explaining some of the unusual detection characteristics that occur under certain hias conditions. For example, in the vicinity of its inflection hias point, a tmmel diode exhibits a discriminator-like rectification behavior with two sensitivity peaks. When biased at one of these peaks, the diode is capable of unusua...

This paper describes three ways to fix antenna problems: (1) diode dropping, (2) jumper insertion, and (3) diode dropping with extension wires. Basic principles of these methods are compared and results are presented. Diode structures, SPIC simulation, and diode slicing are also discussed in this paper.

This paper focuses on single-diode photovoltaic cell models. Comprehensive simulation studies are carried out in order to adequately assess temperature dependence, solar radiation change, diode ideality factor and series resistance influence. A comparison between an ideal model single-diode solar cell and a model of single-diode solar cell with a series resistance is also presented. Finally, co...
