Dec 28, 2023 · Children aged three to eight should have a lot of fun with this slightly messy project that should only take less than 30 minutes. To make the Cardboard Tube Kazoo, you’ll need wax paper, toilet paper tubes, rubber bands, a pen, markers, crayons, and stickers. This is a fun DIY homemade instrument to experiment with.
Aug 1, 2022 · Herein, we summarized novel nanomaterial-based sensors for heavy metal ions analysis, based on the ICP-MS, colorimetric, electrochemistry, SERS, and fluorescence technologies. This review keeps an eye on the fabrication, analytical performances, applications, and potential perspectives of these attractive metal-ion sensors ( Fig. 1 B).
Oct 28, 2022 · This is formed into sheets of paper using a very basic frame made of two parts: a metal mesh called a mold that sits inside a wooden frame known as a deckle (a bit like a picture frame). The mold and deckle are dipped into the half stuff and gently agitated so an even coating forms on top, with most of the water (and some of the pulp) draining ...
