Why Food Sticks to Nonstick Frying Pans

Foods will sometimes get stuck to a heated surface, even if oil or a nonstick frying pan is used. Scientists have investigated the fluid properties of oil on a flat surface and their work, reported in Physics of Fluids, shows convection may be to blame. When the pan is heated from below, a temperature gradient is established in the oil film, as well as a surface tension gradient. This gradient sets up a type of convection known as thermocapillary convection.

Geoengineering is Just a Partial Solution to Fight Climate Change

Could we create massive sulfuric acid clouds that limit global warming and help meet the 2015 Paris international climate goals, while reducing unintended impacts? Yes, in theory, according to a Rutgers co-authored study in the journal Earth System Dynamics. Spraying sulfur dioxide into the upper atmosphere at different locations, to form sulfuric acid clouds that block some solar radiation, could be adjusted every year to keep global warming at levels set in the Paris goals. Such technology is known as geoengineering or climate intervention.

Simulating Borehole Ballooning Helps Ensure Safe Drilling of Deep-Water Oil, Gas

A device which simulates borehole ballooning, a detrimental side effect of deep-water drilling operations, is expected to ensure safe and efficient operations. If not prevented, borehole ballooning can lead to irreversible damage and serious drilling accidents, which can result in reservoir pollution and huge economic loss. In Review of Scientific Instruments, researchers present a device that can simulate this dangerous phenomenon in the hopes of preventing it.

Oils added to vaping products cause damage to lungs, expert says

In response to a new study which found that lung damage from vaping resembles chemical burns, Geraldine R. Britton, director of the Binghamton University Interdisciplinary Tobacco Use Research Program, offers the following. “Many have believed that the underlying problem with vaping…
