Deep Wet and Dry Etching of Pyrex Glass: a Review
This paper is a review of wet and dry etching of one of the most common types of glass: Pyrex. The paper analyzes the methods for increasing the glass etch rate in HF solutions, namely, annealing, concentration, ultrasonic agitation and temperature. The limitations of the wet etching of glass are also presented. Mashing layers commonly used for deep wet etching of glass are analyzed, in terms o...
متن کاملFormation of gallium arsenide nanostructures in Pyrex glass.
In this paper, we report on a simple, low-cost process to grow GaAs nanostructures of a few nm diameter and ∼50 nm height in Pyrex glass wafers. These nanostructures were grown by sequential plasma activation of GaAs and Pyrex glass surfaces using a low-temperature hybrid plasma bonding technology in air. Raman analyses of the activated surfaces show gallium oxide and arsenic oxide, as well as ...
متن کاملA crystal ball made of agents
— This article presents an agent-based solution to model the opinions of an experts group with the aim of predicting possible future scenarios. The need to envision the future is not new; it has existed since the beginning of humankind. What it is new is the applicable technology that is available in a specific period of time. It is not usual to find a critical social system which evolves accor...

Rapid synthesis of nucleotide pyrophosphate linkages in a ball mill.
Using a ball mill, rapid, atom-economic coupling between adenosine-5'-phosphoromorpholidate and phosphorylated ribose derivatives as their sodium or barium salts was achieved. Facile purification by reversed-phase HPLC enabled product isolation within hours.
