In this project, I’ll show you how to turn plain toffee and mint tins into beautiful boxes suitable for display. This project is about more than just decorating the surface—I’ll show you how to etch into thei
Salt Water Metal Etching I am a sword and knife enthusiast who always found the little etching on the side of my weapons super cool. I searched the web for several ways to make my own etchings on my weapons. To my dismay, there were few methods that did not contain harsh, dangerous ch...
This one is a straight salt water etch with a bit of black paint to bring up the details and a finish lacquer coat. This is a salt etch with a layer of copper applied using the cotton swab method and blue vitriol solution. It was then polished with a buffing wheel and a bit of rou...
of water with the 1/2 t. salt in a jar and stir. Add a bunch of Q-tips to the jar. Hook one wire from the positive terminal of the battery to the metal of the water bottle. Hook the other wire from the negative terminal of the battery to the wet end of one of the Q-tips....
Very recently, Z nCl2 Lewis acidic salt was employed to etch Ti3AlC2 MAX, which was based on the replacement reac- tion between Z n2+ cations and zero-valence Al of T i3AlC2 MAX, finally leading to Zn metal-decorated multi-layered Ti3C2Cl2 MXene ...
FIELD: electricity.;SUBSTANCE: in etching method of silicon substrate with formation of silicon columns the substrate is kept in water solution of hydrofluoric acid or its salt, at concentration of 1.5 to 10 M, metal salt at content of 5 to 100 mM, which is capable of chemical deposition ...
leading to Zn metal-decorated multi-layered Ti3C2Cl2MXene [66]. This strategy was further developed into a general route by using various Lewis acidic molten salts etchants to synthesize MXenes [67]. Compared with HF or LiF/HCl etching, Lewis acidic molten salts etching strategy demonstrates a...
An oil-in-water emulsion will conduct electricity with relatively low resistance since water forms its external or continuous phase, whereas a water-in-oil emulsion will not conduct, or very poorly conduct, electricity.As used herein, “oil phase” in a water-in-oil emulsion refers to all ...
For instance, a conventional A2/O process consumes about 32,500 kW h of electricity to treat 100,000 tons of domestic wastewater (Yu et al., 2010). On the other hand, biological remediation systems are encouraged because they are minimally invasive, sustainable, cost-effective, and can be ...
a step of removing metal ions among the waste fluid by diffusion dialysis and ion exchange; a step of removing excessive water generated in recycling the waste fluid by performing distillation with a distiller; and a step of controlling a composition ratio by adding lost components after recycling...
