Scientists Made a New Metal, and it Makes Nuclear Reactors Even Stronger

Posted by in categories: materials, nuclear energy

An international team of researchers has developed a new type of metal alloy that could make nuclear reactors safer and more stable in the long term. The new material is stronger and lasts longer than steel.

Scientists have developed a new kind of high quality metal alloy that is suitable to use in building nuclear reactors. While it might not be a metal that has been invented entirely from scratch, it’s only recently that we have been able to produce this kind (this quality) of metal. And it could mean great things for nuclear technologies.

Modified NWChem Code Utilizes Supercomputer Parallelization

Posted by in categories: chemistry, climatology, evolution, materials, quantum physics, supercomputing

Quicker time to discovery. That’s what scientists focused on quantum chemistry are looking for. According to Bert de Jong, Computational Chemistry, Materials and Climate Group Lead, Computational Research Division, Lawrence Berkeley National Lab (LBNL), “I’m a computational chemist working extensively with experimentalists doing interdisciplinary research. To shorten time to scientific discovery, I need to be able to run simulations at near-real-time, or at least overnight, to drive or guide the next experiments.” Changes must be made in the HPC software used in quantum chemistry research to take advantage of advanced HPC systems to meet the research needs of scientists both today and in the future.

NWChem is a widely used open source software computational chemistry package that includes both quantum chemical and molecular dynamics functionality. The NWChem project started around the mid-1990s, and the code was designed from the beginning to take advantage of parallel computer systems. NWChem is actively developed by a consortium of developers and maintained by the Environmental Molecular Sciences Laboratory (EMSL) located at the Pacific Northwest National Laboratory (PNNL) in Washington State. NWChem aims to provide its users with computational chemistry tools that are scalable both in their ability to treat large scientific computational chemistry problems efficiently, and in their use of available parallel computing resources from high-performance parallel supercomputers to conventional workstation clusters.

“Rapid evolution of the computational hardware also requires significant effort geared toward the modernization of the code to meet current research needs,” states Karol Kowalski, Capability Lead for NWChem Development at PNNL.

Robot-Built Landing Pad Could Pave the Way for Construction on Mars

Posted by in categories: materials, robotics/AI, space

A robot has built a prototype launch-and-landing pad in Hawaii, potentially helping pave the way for automated construction projects on the moon and Mars.

The robotic rover, named Helelani, assembled the pad on Hawaii’s Big Island late last year, putting together 100 pavers made of locally available material in an effort to prove out technology that could do similar work in space.

“The construction project is really unique. Instead of concrete for the landing pad, we’re using lunar and Mars material, which is exactly like the material we have here on the Big Island — basalt,” Rob Kelso, executive director of the Pacific International Space Center for Exploration (PISCES) in Hawaii, told Hawaiian news outlet Big Island Now. PISCES partnered with NASA on the project, which is part of a larger program called Additive Construction with Mobile Emplacement, or ACME for short. [The Boldest Mars Missions in History].

NASA is in the process of getting another peer reviewed EMDrive paper published

Posted by in categories: materials, space travel

Paul March also endorsed the technical information and insights of forum member Rodal on the topic of EMdrive. Rodal indicates the differences in dielectric materials and other nuances of interpreting the known results.

A radio frequency (RF) resonant cavity thruster is a proposed new type of electromagnetic thruster. Unlike conventional electromagnetic thrusters, a resonant cavity thruster would use no reaction mass, and emit no directional radiation.

A few variations on such thrusters have been proposed. Aerospace engineer Roger Shawyer designed the EmDrive in 2001, and has persistently promoted the idea since then through his company, Satellite Propulsion Research.

You can now 3D print the world’s lightest material – graphene aerogel

Posted by in categories: 3D printing, materials

YES PLEASE.

It’s 7.5 times lighter than air, and a cubic metre of the stuff weighs just 160 grams. It’s 12 percent lighter than the second lightest material in the world – aerographite – and you can balance a few cubic centimetres of the stuff on a dandelion head. Water is about 1,000 times as dense.

Remarkable nanowires could let computers of the future grow their own chips

Posted by in categories: computing, engineering, materials, mobile phones, nanotechnology, particle physics, robotics/AI

Now, we’re hitting Terminator mode with this.


If you’re worried that artificial intelligence will take over the world now that computers are powerful enough to outsmart humans at incredibly complex games, then you’re not going to like the idea that someday computers will be able to simply build their own chips without any help from humans. That’s not the case just yet, but researchers did come up with a way to grow metal wires at a molecular level.

At the same time, this is a remarkable innovation that paves the way for a future where computers are able to create high-end chip solutions just as a plant would grow leaves, rather than having humans develop computer chips using complicated nanoengineering techniques.

Rapid Superconducting Memory Cell Control System Developed

Posted by in categories: computing, information science, materials, quantum physics

“With the operational function that we have proposed in these memory cells, there will be no need for time-consuming magnetization and demagnetization processes. This means that read and write operations will take only a few hundred picoseconds, depending on the materials and the geometry of the particular system, while conventional methods take hundreds or thousands of times longer than this,” said the study author Alexander Golubov, the head of Moscow Institute of Physics and Technology (MIPT)’s Laboratory of Quantum Topological Phenomena in Superconducting Systems.

Golubov and colleagues at Moscow State University have proposed creating basic memory cells based on quantum effects in superconductor “sandwiches.” Superconductors were predicted in the 1960s by the British physicist Brian Josephson. The electrons in these “sandwiches,” called “Josephson junctions,” are able to tunnel from one layer of a superconductor to another, passing through the dielectric like balls passing through a perforated wall.

Today, Josephson junctions are used both in quantum devices and conventional devices. For example, superconducting qubits are used to build the D-wave quantum system, which is capable of finding the minima of complex functions using the quantum annealing algorithm. There are also ultra-fast analogue-to-digital converters, devices to detect consecutive events, and other systems that do not require fast access to large amounts of memory. There have also been attempts to use the Josephson Effect to create ordinary processors. An experimental processor of this type was created in Japan in the late 1980s. In 2014, the research agency IAPRA resumed its attempts to create a prototype of a superconducting computer.
