PulseSelect and PFA catheters from other device developers use gold or platinum-iridium electrodes. But Medtronic’s Affera Sphere-9 PFA system uses the entire expanding nitinol structure as a global ...

National Cancer Institute researchers have developed a method called HORNET for characterizing 3D topological structures of large and flexible RNA molecules. Scientists used atomic force ...

The antenna was 3D printed from a nickel-titanium alloy, also known as Nitinol, one of the most popular shape memory alloys. This means that the alloy can recover its original shape after deformation ...

Current atomic interferometers rely on nanomechanical membranes, but increased momentum transfer via crystal gratings could make interferometers even more sensitive. On September 14, 2015 ...

A model showing how metallic bonds are formed - the first diagram shows the outer electrons in their atoms, and the second diagram shows that the electrons have become delocalised ...

One of my least favorite tropes of comic book storytelling is when an issue opens in the middle of an action-packed sequence before flashing back to some time before the proverbial excrement hits ...

Direct visualization of a solid-state transformation between two extra-large pore siliceous zeolites reveals a discrete sequence of bond breakage and formation steps at the atomic scale.

The IAEA is the world's centre for cooperation in the nuclear field. It was set up as the world's "Atoms for Peace" organization in 1957 within the United Nations family. The Agency works with its ...

A new high-tech atomic clock has been developed by scientists at the top-secret Defence Science and Technology Laboratory (Dstl). It is expected to be a leap forward for intelligence, surveillance ...

Covalent bonding close covalent bondA bond between atoms formed when atoms share electrons to achieve a full outer shell of electrons. leads to the formation of substances with different types of ...

The country’s first hydrogen bomb test occurred on December 28, 1966, with an explosive yield of 122 kilotons. Six months later, on June 17, 1967, China tested a full-yield device, producing an ...
