Abstract: A light emitting diode (LED), and a method for producing the same. The LED includes a substrate that may be made of silicon, a first conductive layer on one side, and a porous insulating layer on the opposite side. The insulating layer defines microcavities therein, the microcavities having sharp tips on their inner surfaces. The microcavities have gas inside. A second conductive layer is disposed over the insulating layer. When an electrical potential is applied between the conductive layers, the gas-filled microcavities act as plasma discharge lamps, emitting light. The light may be in the ultraviolet portion of the spectrum. The method includes etching a substrate to produce a porous insulating layer on one side, depositing a first conductive layer on the opposite side, and depositing a second conductive layer over the insulating layer. The microcavities in the insulating layer are then filled with gas.

Abstract: A serial battery charger including a number of serially connected battery charging sections in which the battery charging section is characterized by a first and second parallelly connected branches. The first branch includes terminals for connecting to the battery to be charged and a current blocking device and the second branch includes a by-passing switch which shunts across the terminals of the first branch when activated. The blocking device in the first branch prevents adverse reverse current flow from the battery to the charger when there is no power supply and also functions as a current block to prevent adverse flow of current from the battery into the shunting by-passing switch when the power supply to the charging section is in operation. This invention provides a simple solution to fulfil the conflicting requirements of an intelligent serial battery charger.

Abstract: The present invention discloses the doping of rare earth elements into porous silicon, resulting in enhancement of luminescence. The doping is an electro-chemical process using constant voltage bias across the two electrodes in which the anode is porous silicon and the cathode is platinum. The doping process involves a well-defined solution of electrolytes that controls the conductivity of the solution, and set values of constant voltages that selectively allow the desired rare earth elements being doped into porous silicon.

Abstract: The present invention is an improved method of making a partially modified PCR product from a DNA fragment with a polymerase chain reaction (PCR). In a standard PCR process, the DNA fragment is combined with starting deoxynucleoside triphosphates, a primer, a buffer and a DNA polymerase in a PCR mixture. The PCR mixture is then reacted in the PCR producing copies of the DNA fragment. The improvement of the present invention is adding an amount of a modifier at any step prior to completion of the PCR process thereby randomly and partially modifying the copies of the DNA fragment as a partially modified PCR product. The partially modified PCR product may then be digested with an enzyme that cuts the partially modified PCR product at unmodified sites thereby producing an array of DNA restriction fragments.
