5g), because of the advances in 3D printing technologies, which could, in principle, scale the pore size from the micrometer to the meter scales, and use different constitutive materials, targeting different applications (such as different water purification scenes). Meanwhile, it is even possible...
A tool for fitting and removal of a water meter on a pipeline has a cylindrical grip (1), open to the bottom and which fits onto the meter. The closed top of the tool has a central bore and two offset bores equally spaced on the same diagonal through the central bore. The holes ...
The present invention relates to a freeze-prevention water meter, and more particularly, to a water meter having an air bag capable of absorbing the inflated volume by contraction even if the water inside the water meter freezes in winter.;Freeze protection water meter according to the present ...
membrane surface to get a free-standing EGO paper. For tensile strength measurements, the EGO paper was cut into narrow strips with a dimension of 10 × 2 mm2, and measured with a Hounsfield H5K-S materials tester. The thickness of the strip was measured with a spiral micrometer. ...
Fluorescence was recorded on a FluoroMax-3 fluorimeter (Jobin Yvon-Spex, Edison, NJ) in 1.0-cm rectangular cuvettes with excitation at 330 nm (an excitation slit of 3 nm and an emission slit of 3 nm) in photon counting mode. Epifluorescence microscopy was carried out on an inverted microsc...
Self-assembly can be a powerful, but simple, synthetic method for the fabrication and surface modification of nanometer- to micrometer-sized hollow spheres. Here we report a facile route for preparation of submicrometer ferrite hollow sp... Li, Xin-Hao,Zhang, Dong-Hui,Chen, Jie-Sheng - 《Jo...

UV based devices for household purposes should be located at the water inlet in conjunction with the water meter, or immediately prior to the location of drinking water outlet(s). This can be followed by a cost-effective chlorine injector at the outlet when the household sewage joins the ...
The membrane thickness was measured ex situ with a micrometer gauge (74 µm) and is assumed incompressible. Before cell assembly, the membrane was ion exchanged by immersing it in a 1 M potassium hydroxide solution (made from ACS reagent ≥85% pellets, Sigma-Aldrich and deionized water...
