Hollow nanosized needles, or nanostraws, are a promising tool for opening up tiny, temporary holes in cell membranes to deliver molecules or sample a cell’s contents. Nanostraws could also deliver ...

Scientists have combined 3-D-printing with electroplating to easily produce high-quality metal electrodes that can be used as a molecular beam-splitter. Many measurement techniques, such as ...

The process that makes gold-plated jewelry or chrome car accents is now making powerful lithium-ion batteries. Researchers at the University of Illinois, Xerion Advanced Battery Corporation and ...

AT a meeting of the Royal Society of Arts on February 2, a paper by Mr. A. Rosenberg was read upon an improved method of electroplating. Mr. Rosenberg dispenses altogether with the plating bath and ...

Many measurement techniques, such as spectroscopy, benefit from the ability to split a single beam of light into two in order to measure changes in one of them. The crucial device that separates the ...
