New 3D printing process paints graphene aerogel in far finer detail
Graphene is famous as a two-dimensional material, but to really make the most of the stuff we need to coax it back into 3D forms. Now researchers from Virginia Tech have developed a new way to 3D print graphene aerogels with a far higher resolution than previously possible.
Researchers are developing fast-charging solid-state batteries
Solid-state batteries contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling, and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Juelich scientists have now introduced a new concept that allows currents up to 10 times greater during charging and discharging than previously described in the literature.
Low current is considered one of the biggest hurdles in the development of solid-state batteries because the batteries take a relatively long time to charge, usually about 10 to 12 hours in the case of a fully discharged battery. The new cell type that Jülich scientists have designed, however, takes less than an hour to recharge.
“With the concepts described to date, only very small charge and discharge currents were possible due to problems at the internal solid-state interfaces. This is where our concept based on a favourable combination of materials comes into play, and we have already patented it,” explains Dr. Hermann Tempel, group leader at the Juelich Institute for Energy and Climate Research (IEK-9).
Stacking concrete blocks is a surprisingly efficient way to store energy
To deal with variable solar and wind power, the startup Energy Vault is coming out of stealth mode to offer alternatives to lithium-ion batteries.
Institute for Advanced Studies At Austin
The ADAM Research Project, an acronym for Acquisition & Data Analysis of Materials, will focus on the collection and scientific evaluation of material samples obtained through reliable reports of advanced aerospace vehicles of unknown origin.
As a first step, TTS Academy has established a contract with EarthTech International, Inc., (www.earthtech.org) a well-respected research think tank in Austin, Texas, to evaluate the properties of the available materials. Under the leadership of Dr. Harold E. Puthoff, a former Senior Advisor and Subcontractor to the Pentagonfs AATIP program (Advanced Aerospace Threat Identification Program) and current VP of Technology for TTS Academy, EarthTech is well-positioned to head up this materials research plan.
Intel 9th Gen Core CPU and Z390 Platform Launches on 1st October
Intel is prepping their latest mainstream processor lineup for release soon. As part of the 9th Gen family, the new processors will come with more cores and faster clocks, all thanks to improvements in the 14nm process node. Now, we have details on when the new processors will launch and be available in retail channels.
Intel To Launch 9th Generation Unlocked Processors Including Flagship Core i9-9900K 8 Core, 16 Thread Chip on 1st October
We have known that the 9th Generation Core desktop processors are arriving on the mainstream platform soon but we haven’t had a concrete launch date, till now. Our sources report that Intel is planning to launch their unlocked SKU family along with the Z390 series on 1st October which does confirm previous rumors. As expected, the launch will include all three unlocked SKUs which are mentioned below along with their specifications:

Physicists find surprising distortions in high-temperature superconductors
There’s a literal disturbance in the force that alters what physicists have long thought of as a characteristic of superconductivity, according to Rice University scientists.
Rice physicists Pengcheng Dai and Andriy Nevidomskyy and their colleagues used simulations and neutron scattering experiments that show the atomic structure of materials to reveal tiny distortions of the crystal lattice in a so-called iron pnictide compound of sodium, iron, nickel and arsenic.
These local distortions were observed among the otherwise symmetrical atomic order in the material at ultracold temperatures near the point of optimal superconductivity. They indicate researchers may have some wiggle room as they work to increase the temperature at which iron pnictides become superconductors.
Here’s how many times you actually need to reuse your shopping bags
The plastic bag ban by the major supermarkets (and Coles’ pivot away from its ban after backlash, then pivot back to the ban after a backlash to the backlash) has left plenty of people scratching their heads.
What are the best replacements for single-use plastic bags? Given that reusable bags are much sturdier, how many times must we use them to compensate for their larger environmental impact?
The simple answer is that there is no simple answer. However, a kind of research called “life cycle assessment” can help us work out the impact of common types of reusable bags.
