    • A method of forming an array of electrically addressable cells, comprising the steps of: a forming a set of parallel conductor strips 4, extending in a first direction, on an insulating substrate 2 b forming an insulating layer superimposed on the first series of parallel strips c forming a second set of parallel conductor strips 6, extending in a direction at right angles to the first direction, superimposed on the insulating layer so as to form crossover regions between the strips, and d forming wells in the structure which extend through the conductor strips, so that the wells at the crossover regions can be addressed electronically in the conductor strips. The addressable array of cells can then be used for selectively reacting a substance with a series of different reagents by a method which involves addressing selected groups of cells with electrical signals using the matrix of conductor strips, and applying an electrolyte to the array in such a way that the selected cells can either be shuttered by gas bubbles formed by the electrolyte, to protect them from reaction, or can be subjected to a local change in pH which promotes a reaction. In this way a matrix of chemicals can be synthesised so that the composition and spatial position is known for each component of the matrix.
    • 一种形成电可寻址单元阵列的方法,包括以下步骤:在绝缘基板2B上形成一组平行的导体条4,该平行导体条4在第一方向上延伸,形成叠置在第一系列平行条上的绝缘层 c形成第二组平行导体条6,其沿与第一方向成直角的方向延伸,叠加在绝缘层上,以在条之间形成交叉区域,并且d形成在结构中延伸穿过导体的孔 使得可以在导体条中以电子方式对交叉区域处的孔进行寻址。 然后可寻址的单元阵列可以用于通过一种方法选择性地使物质与一系列不同的试剂反应,该方法涉及使用导体条的矩阵来利用电信号寻址选定的电池组,以及将电解质施加到阵列中 所选择的电池可以被电解质形成的气泡所切断,以保护它们免受反应,或者可能会导致pH的局部变化,从而促进反应。 以这种方式,可以合成化学品矩阵,使得组合物和空间位置对于矩阵的每个组分是已知的。

    • The present invention provides a process for etching silicon to form pillars, which may be used as an anode material in a Li-ion battery; the process involves depositing silver onto silicon as part of the etching procedure. An etched silicon particle is shown in Figure 1. The silver present after the silicon has been etched can be removed by treatment with nitric acid. This removed silver can be recycled, thereby reducing the costs of the overall process. In one embodiment, the process comprises: - treating silicon, e.g. granules or bulk material, with an etching solution comprising HF, Ag+ ions and nitrate ions, thereby etching the silicon to form silicon having etched pillars on its surface; the silicon includes a surface deposit of silver, - separating the etched silicon from the spent etching solution, - dissolving the silver from the etched silicon using nitric acid to form a solution containing Ag+ ions and nitrate ions, - mixing the solution containing Ag+ ions and nitrate ions with further HF to form a further etching solution, and - using the further etching solution to treat further silicon.
