The direct oxidative coupling of phenylazoles with internal alkynes proceeds efficiently in the presence of a rhodium catalyst and a copper oxidant accompanied by double or quadruple C−H bond ...

In this video I show how to make a landmine with a remote charge for use in airsoft or paintball. Baking soda is used in the charge because it is cheap, non toxic, and not flammable. If you like this ...

The final, formatted version of the article will be published soon. This manuscript introduces an innovative and environmentally benign magnetic nanocatalyst (NiFe2O4@MCM-41@IL/Pt(II)) designed to ...

PVC fittings. Cut 1-in. PVC pipe into 3-in ... PVC pipe is labeled by inside diameter; here's an index for the outside diameter of useful pipe sizes. 1/2-in. i.d. = 7/8-in. o.d. 3/4-in. i.d. = 1-in. o ...

The increasingly widespread application of superconducting nanowire single-photon detectors (SNSPDs) in space quantum communication, satellite laser ranging, and optical quantum computing has also ...

A new, systematic way of coupling low-frequency finite-element (FE) models with circuit systems is proposed using a modified nodal analysis framework. Solid and filamentary conductors can be equally ...
