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]
More than 350,000 people in California live in towns sited completely within zones deemed to be at very high risk of fire. In total, more than 2.7 million people live in "very high fire hazard severity zones", which also include areas at lesser risk. [9] Climate change in California has lengthened the fire season and made it more extreme. [10] [11]
Wastewater plants are failing to remove a group of potentially toxic chemicals before pumping treated water into rivers and lakes — and climate change may be making the situation even worse, a ...
San Francisco’s Department of Emergency Management issued a statement about the tornado warning, noting that residents were "understandably anxious” to receive an alert so uncommon for the region.
It is a highly effective fire suppression method for class A, B, C, E and F (as is the case for most fire-extinguishing agents, it is not applicable to metal fires – class D). [1] Some aerosol-generating compounds (e.g., potassium nitrate -based) produce a corrosive by-product that may damage electronic equipment, although later generations ...
California has approximately 1,100 dairies, mostly concentrated in the state's fertile Central Valley, that produce approximately 41 billion gallons of milk annually for an economic value of ...
Dulse is one of many edible algae. Algaculture may become an important part of a healthy and sustainable food system [11]. Several species of algae are raised for food. While algae have qualities of a sustainable food source, "producing highly digestible proteins, lipids, and carbohydrates, and are rich in essential fatty acids, vitamins, and minerals" and e.g. having a high protein ...
