Glue

Perhaps you've had one or more of the following experiences when trying to stick items together using super glue: the glue sets before the objects can be properly aligned, it won't set fast enough, or it hardens inside the bottle once it's been opened. Well, Bondic is claimed to have none of those problems. It's described as a "liquid plastic welder" that sets within four seconds, but only once it's been exposed to an included UV light. Read More
Clingy barnacles might be something of a nuisance for seafarers, but these stubborn shellfish and their relatives could hold the key to a new breed of sticky materials. Engineers from MIT have created waterproof adhesives based on the proteins that give these creatures such qualities, a development that could one day be used in ship repairs or medical applications.

If you place pretty much any type of solid material in the ocean, barnacles will firmly attach themselves to it. If you were to try applying a glue to any of those materials while they were underwater, however, it likely wouldn't stick. So, what do barnacles know that we don't? Scientists have recently discovered the answer, and it could lead to advances in human technologies. Read More
In recent years we've seen a number of attempts at artificially replicating the strong-yet-light characteristics of spider silk. It turns out that the silk itself isn't the only thing that's inspiring scientists, however. Researchers from the University of Akron have recently created their own version of the "attachment discs" that spiders use to secure their silk fibers to surfaces, when building webs. These man-made discs could conceivably prove superior to conventional glues as a form of adhesive. Read More
When soldiers or other people sustain eye injuries, retinal detachment and vision loss can result if the eye's vitreous gel isn't kept from leaking out. Given that Band-Aids can't be placed directly on the eyeball, however, a team of scientists from the University of Southern California has created an alternative – reversible eye glue. Read More
It has been estimated that up to 85 percent of all wood materials (such as particleboard or plywood) contain adhesives that in turn contain formaldehyde, and the World Health Organization has classified formaldehyde as a carcinogen. Unfortunately, it’s not enough to simply avoid eating those wood products – even the fumes given off by formaldehyde have been shown to pose a health hazard. Many people turn to keeping spider plants in their homes or offices, as they help neutralize airborne toxins, but now help could be coming from another source. German researchers have discovered that by adding special minerals to wood adhesives, those adhesives themselves can help clean the air. Read More
Stories about Kryptonite are sure to pique interest, and this one has both a "super" and a scientific angle. Canadian researchers are using a super glue called Kryptonite to create a stronger closure of the breastbone for heart patients after open chest surgery. This means faster recovery time, fewer complications and less post-operative pain. Read More
Two thousand years ago Jesus may have walked on water, but soon we may be walking on food. In a bid to become more environmentally sustainable, scientists have unveiled a new "green" alternative to commonly used petroleum-based wood adhesives. Representatives from the U.S. Department of Agriculture (USDA) Forest Products Laboratory in Wisconsin, speaking at this week's 240th National Meeting of the American Chemical Society, talked about the development of a soy-based glue. The substance is derived from food products such as soy milk and tofu, and could mean a new generation of eco-friendly flooring, furniture, cabinets and other wood products. Read More
It happens often in research. While looking for one thing, scientists stumble across another. In this case, researchers at Oregon State University's College of Forestry were looking for an elusive wood-based adhesive that would be solid at room temperature but melt when the heat was turned up. What they stumbled upon was an easily produced, environmentally benign, pressure sensitive adhesive which holds the potential to be cheaply produced from a wide range of vegetable oils. Read More
Could you confidently gallivant under huge mushroom-like structures knowing that they had been glued – not bolted – together? The architects and engineers of the “Parasols” in Seville, Spain, certainly hope so because the design features components that are stuck to each other in such a way. Understandably, they say the biggest problem was finding a glue that could withstand 60°C (140°F) and therefore wouldn’t melt in Seville’s summer heat. This is a fairly important criterion for the free-standing parasols that cover an area of 150m x 70m - one of the largest architectural timber structures ever built. Researchers from the Fraunhofer Institute for Wood Research WKI in Germany have adhered to the challenge and stuck with a formula they believe will do the job. Read More
