What are the chances that a particle collider's strangelets will destroy the Earth?
Oldest bit of crust firms up idea of a cool early Earth
With the help of a tiny fragment of zircon extracted from a remote rock outcrop in Australia, the picture of how our planet became habitable to life about 4.4 billion years ago is coming into sharper focus.
New 'pomegranate-inspired' design solves problems for lithium-ion batteries
with silicon nanoparticles clustered like seeds in a tough carbon rind – overcomes several remaining obstacles to using silicon for a new generation of lithium-ion batteries, say its inventors at Stanford ...
Team builds nonflammable lithium ion battery
In studying a material that prevents marine life from sticking to the bottom of ships, researchers led by chemist Joseph DeSimone at the University of North Carolina at Chapel Hill have identified a surprising replacement ...
Too many electrons at the lithiation front in silicon are a problem
(Phys.org) —Ubiquitous but frustrating, lithium-ion batteries fade because the materials lose their structure in response to charging and discharging. This structural change is closely related to the formation ...
Pumping iron: A hydrogel actuator with mussel tone
(Phys.org) —Protein from a small, tasty mollusk inspired Michigan Technological University's Bruce P. Lee to invent a new type of hydrogel actuator.
New catalyst could lead to cleaner energy
MIT chemists have devised a way to trap carbon dioxide and transform it into useful organic compounds, using a simple metal complex.
Exchange of bismuth atoms for chloride ions with retention of structure
Modern technology makes extensive use of ion exchangers. For example, they are commonly used to decalcify water by binding calcium ions and releasing sodium ions in return. Good exchangers tend ...
Tesla unveils 'Gigafactory' to ramp up mass-market car
Tesla Motors unveiled plans Wednesday for a so-called "Gigafactory" for advanced electric car batteries as part of a plan to move from niche manufacturer to mass market carmaker.
New technique produces highly selective filter materials
Researchers have devised a way of making tiny holes of controllable size in sheets of graphene, a development that could lead to ultrathin filters for improved desalination or water purification.
Novel technique for electrical activation of implanted material without co-implantation
Researchers at the Naval Research Laboratory in Washington, USA, have implanted Mg in GaN and employed a novel high-temperature annealing technique that has realised electrical activation of implanted material ...
ORNL microscopy system delivers real-time view of battery electrochemistry
Using a new microscopy method, researchers at the Department of Energy's Oak Ridge National Laboratory can image and measure electrochemical processes in batteries in real time and at nanoscale resolution.
Scientists recreating early universe quark-gluon plasma in giant particle accelerators
(Phys.org) —In the first few microseconds after the big bang, the universe was a superhot, superdense primordial soup of "quarks" and "gluons," particles of matter and carriers of force respectively. This ...
The core of corrosion
(Phys.org) —Anyone who has ever owned a car in a snowy town – or a boat in a salty sea – can tell you just how expensive corrosion can be.
