Ultra-hard material to rival diamond discovered      (via sciencedaily.com)     Original source 

Scientists have solved a decades-long puzzle and unveiled a near unbreakable substance that could rival diamond, as the hardest material on earth, a study says. Researchers found that when carbon and nitrogen precursors were subjected to extreme heat and pressure, the resulting materials -- known as carbon nitrides -- were tougher than cubic boron nitride, the second hardest material after diamond.

Veins of bacteria could form a self-healing system for concrete infrastructure      (via sciencedaily.com)     Original source 

In hopes of producing concrete structures that can repair their cracks, researchers are putting a new twist on an old trick for improving the durability of concrete. Fiber reinforcement has been around since the first masons were mixing horsehair into their mud. But this research team is taking this method to the next level by turning reinforcing fibers into a living tissue system that rushes concrete-healing bacteria to the site of cracks to repair the damage.

Ancient stars made extraordinarily heavy elements      (via sciencedaily.com)     Original source 

How heavy can an element be? An international team of researchers has found that ancient stars were capable of producing elements with atomic masses greater than 260, heavier than any element on the periodic table found naturally on Earth. The finding deepens our understanding of element formation in stars.

Catalyst for electronically controlled C--H functionalization      (via sciencedaily.com)     Original source 

Scientists chipping away at one of the great challenges of metal-catalyzed C--H functionalization with a new method that uses a cobalt catalyst to differentiate between bonds in fluoroarenes, functionalizing them based on their intrinsic electronic properties. And their method is fast -- comparable in speed to those that rely on iridium.

Chemists create organic molecules in a rainbow of colors      (via sciencedaily.com)     Original source 

Chemists have now come up with a way to make molecules known as acenes more stable, allowing them to synthesize acenes of varying lengths. Using their new approach, they were able to build molecules that emit red, orange, yellow, green, or blue light, which could make acenes easier to deploy in a variety of applications.

Recycling concrete using carbon can reduce emissions and waste      (via sciencedaily.com)     Original source 

Amid the rubble of large-sale earthquake, war or other disaster -- and as ageing buildings and infrastructure are replaced -- mountains of concrete are often taken to landfill or pounded into rubble for roads. For a more sustainable approach, experts are developing a 'value add' for old broken concrete to 'upcycling' coarse aggregate to produce a strong, durable and workable concrete using a small amount of a secret ingredient -- graphene.

Control over friction, from small to large scales      (via sciencedaily.com)     Original source 

Friction is hard to predict and control, especially since surfaces that come in contact are rarely perfectly flat. New experiments demonstrate that the amount of friction between two silicon surfaces, even at large scales, is determined by the forming and rupturing of microscopic chemical bonds between them. This makes it possible to control the amount of friction using surface chemistry techniques.

Unsafe lead levels in school drinking water: new study IDs building risk factors      (via sciencedaily.com)     Original source 

Civil and environmental engineers have determined the factors that may help identify the schools and daycare centers at greatest risk for elevated levels of lead in drinking water. The most telling characteristic for schools in Massachusetts is building age, with facilities built in the 1960s and 1970s -- nearly a third of the facilities tested -- at the greatest risk for having dangerously high water lead levels.
