In 1994, a study by Phil Attard, John L. Parker, and Per M. Claesson further theorized about the existence of nano-sized bubbles, proposing that stable nanobubbles can form on the surface of both hydrophilic and hydrophobic surfaces depending on factors such as the level of saturation and surface tension.
For improving its ability mass-transfer efficiency ozone micro/nano-bubble(MNB) is an important technology. For improving, gas-liquid contact and mass-transfer effectiveness air microbubbles were used. While in the case of ozone, MNB improves the properties of ozonation or oxidation. [6] [7]
[2] [3] It again received an award from IDEA in 2012 for developing Pure Rain, a brand for oxygenating watering systems with a nano bubble generator, for Bluemark Industries. In 2019, Nectar became an ISO 13485:2016 certified company. [ 4 ]
A piezoelectric nanogenerator is an energy-harvesting device capable of converting external kinetic energy into electrical energy via action by a nano-structured piezoelectric material. It is generally used to indicate kinetic energy harvesting devices utilizing nano-scaled piezoelectric material, like in thin-film bulk acoustic resonators. [20 ...
The California Department of Forestry and Fire Protection (CAL FIRE) [2] [3] is the fire department of the California Natural Resources Agency in the U.S. state of California.It is responsible for fire protection in various areas under state responsibility totaling 31 million acres, as well as the administration of the state's private and public forests.

A top Costco executive sounded the alarm on the potential consequences of President-elect Donald Trump’s proposed tariffs — warning that it will raise prices of goods across the board. “When ...
Hypoxic air technology for fire prevention, also known as oxygen reduction system (ORS), is an active fire protection technique based on a permanent reduction of the oxygen concentration in the protected rooms. Unlike traditional fire suppression systems that usually extinguish fire after it is detected, hypoxic air is able to prevent fire.
