Fish, seaweed inspire slippery surfaces for ships
Fish and seaweed secrete a layer of mucus to create a slippery surface, reducing their friction as they travel through water. A potential way to mimic this is by creating lubricant-infused surfaces covered with cavities. As the cavities are continuously filled with the lubricant, a layer is formed over the surface. In the journal Physics of Fluids, researchers in South Korea conducted simulations of this process to help explain the effects. (2020-09-15)

Almost frictionless
Lubricants in bearings and gear units ensure that not too much energy is lost through friction. Yet it still takes a certain percentage of the energy to compensate for friction losses. Lubricants made of liquid crystals could reduce friction to almost zero. (2008-11-10)

Study examines effect of water-based and silicon-based lubricant
A new study by sexual health researchers at Indiana University found that women who used lubricant during sex reported significantly higher levels of satisfaction and pleasure. The study, involving 2,453 women, is the largest systematic study of this kind, despite the widespread commercial availability of lubricant and the gaps in knowledge concerning its role in alleviating pain or contributing to other health issues. The study is published in the Journal of Sexual Medicine. (2010-12-09)

Indiana U. at APHA: Studies about why men and women use lubricants during sex
Personal lubricants have long been recommended to women to improve the comfort of intercourse and to reduce the risk of vaginal tearing, which can increase risks for STIs and HIV. Public health professionals also recommend the addition of lubricant to condoms during sexual activity. Despite this routine advice, strikingly little is known about situations in which lubricants are used or whether there are any associated vaginal symptoms. These studies provide insight into lubricant use. (2009-11-09)

Additives may save energy for cooling big buildings
A National Institute of Standards and Technology (NIST) researcher has come up with a method designed to improve the energy efficiency of water chillers that cool the nation's large commercial buildings. The NIST method, if confirmed through experiments with full-scale chiller systems, could save as much as 1 percent of the 320 billion kWh of electricity used annually by chillers or an equivalent 920,000 barrels of oil a day, according to Mark Kedzierski, the NIST mechanical engineer who developed the technique. (2005-11-17)

Robot control system for grasping and releasing objects under both dry and wet conditions
A control system for deformable robot-fingertips was developed for grasping and releasing objects. Previously developed robot fingertips with high friction texture can stably grasp a paper box, a soft object under both dry and wet conditions. By injecting a lubricant (absolute ethanol) the grasped object slipped downwards without changing the position of the robot fingertips. The current controlling system using lubricant could be applied to robot tasks in a narrow space. (2019-07-16)

(1998-05-25)

Computer simulation discloses new effect of cavitation
Researchers have discovered a so far unknown formation mechanism of cavitation bubbles by means of a model calculation. In the Science Advances journal, they describe how oil-repellent and oil-attracting surfaces influence a passing oil flow. Depending on the viscosity of the oil, a steam bubble forms in the transition area. This so-called cavitation may damage material of e.g. ship propellers or pumps. However, it may also have a positive effect. (2016-03-26)

Help from the stomach for dry eyes
After a long day of working at the computer, scratchy contact lenses are not only painful, over longer periods of time they can also damage ocular tissue. Relief may be in sight from a natural mucus component referred to as a mucin.
