Intel Building New Fabs to Try to Regain Relevance But TSMC Surges Ahead

Intel is trying to get back to being relevant in the Semiconductor game. Intel announced a $20 billion (USD) investment in two new manufacturing facilities (fabs) in Arizona. They will start production in 2024. CEO Pat Gelsinger said the 7nm manufacturing node from Intel is now running on schedule. The first product enabled with 7nm …

Unipolar Carbon Nanotube Muscles: Ten to Thirty Times Human Muscle and Two to Six times Diesel V8

Researchers describe creating powerful, unipolar electrochemical yarn muscles that contract more when driven faster, thereby solving important problems that have limited the applications for these muscles. This polymer coating converts the normal bipolar actuation of carbon nanotube yarns to unipolar actuation, where the muscle actuates in one direction over the entire stability range of the …

Finally, Commercialization of Wafers of Carbon Nanotube Transistor Chips

Carbon nanotube field-effect transistors or CNFETs can now be made 1100 times faster so significant commercialization will finally happen. CNFETs are more energy-efficient than silicon field-effect transistors and could be used to build new types of three-dimensional microprocessors. They found that dry cycling, a method of intermittently drying out the submerged wafer, could dramatically reduce …

29% More Energy Efficient Refrigeration With Multi-Walled Carbon Nanotubes

Power consumption of a home refrigerator can be cut by 29% while improving cooling capacity. Researchers replaced widely-used, but environmentally unfriendly, R134a refrigerant with the more energy-efficient R600a. They dosed R600a with multi-walled carbon nanotube (MWCNT) nanoparticles. A more energy-efficient refrigerant can result in much lower electricity bills. For vulnerable households, energy security can be …

Carbonics 100 GHz Wafer Scale Nanotube Technology Shows Nanotubes Can Finally Compete With Silicon

Carbonics has demonstrated a wafer-scalable approach for producing an array of aligned carbon nanotube (CNT) FETs with performance exceeding 100 GHz and linearity of 10dB. This indicates we could finally be close to a tipping point where nanotubes become a serious competitor to silicon in almost all areas of microelectronics. Wireless device technology operating in …

Fabrication of Ultrastrong 700 Gigapascal Fused Double-walled Carbon Nanotubes

The Clean Energy Research Foundation has discovered a method of manufacturing the worlds strongest and toughest materials. Fused double-walled carbon nanotube (DWNT) fibers were made with a strength of a 700 GPa Young’s modulus. This strength was seen in prior experiments, in 2010 and 2011, where electron beams welded DWNTs in microscopic bundles together and …

China 80 Gigapascal Carbon Nanotube Bundles Were Part of a Prediction from 2006

In 2006, I made about 156 predictions. One of the predictions was that carbon nanotube fiber would be inexpensive and with over 50GPa tensile strength around 2014-2018. Relative to 2006, there is inexpensive carbon nanotubes. Macroscopic carbon nanotube bundles were created in 2018 at Tsinghua university in China and they have 80 Gigapascals of tensile …

Self-Assembled Carbon Nanotube Antennas for Solar Power Revolution

NovaSolix’s carbon nanotube (CNT) antennas are small enough to match the nano-scale wavelengths of sunlight. Antennas can convert electromagnetic spectrum much more efficiently than photovoltaic (PV) cells. When perfected, NovaSolix antennas will capture over four times the energy of current solar panels. They will reach nearly 90% efficiency versus ~20% for todays solar panels. NovaSolix …

Nanotube film enabling ten times higher energy lithium metal batteries

Thin nanotube films effectively stop dendrites that grow naturally from unprotected lithium metal anodes in batteries. Over time, these tentacle-like dendrites can pierce the battery’s electrolyte core and reach the cathode, causing the battery to fail. That problem has mostly stopped the use of lithium metal in commercial applications. Lithium metal charges much faster and …

Superstrong materials for electric spaceplanes instead of space elevators

China has carbon nanotube bundles in the lab that are 20 times stronger than kevlar. They are trying to scale them up for mass production. If they succeed in mass producing tons of this material then what has been impossible become possible engineering. Superstrong materials were the key part of molecular nanotechnology speculation. Carbon nanotube …
