Manufacturing Bits: Feb. 8


Metalens for AR/VR The Harvard John A. Paulson School of Engineering and Applied Sciences has developed a new lens technology for use in next-generation virtual and augmented reality systems. Researchers have developed a so-called metalens technology. The two-millimeter achromatic metalens is capable of focusing the RGB (red, green, blue) colors at once without any aberrations. Today, s... » read more

Zeptosecond measurements A group of researchers have set a new world’s record for the shortest timespan measurement. DESY, Fritz-Haber-Institute and Goethe University Frankfurt have measured how long it takes for a photon to cross a hydrogen molecule. The result? About 247 zeptoseconds. A zeptosecond is a trillionth of a billionth of a second (10-21 seconds). This is said to be the sh... » read more

Power/Performance Bits: Oct. 27


Room-temp superconductivity Researchers at the University of Rochester, University of Nevada Las Vegas, and Intel created a material with superconducting properties at room temperature, the first time this has been observed. The researchers combined hydrogen with carbon and sulfur to photochemically synthesize simple organic-derived carbonaceous sulfur hydride in a diamond anvil cell, which... » read more

Power/Performance Bits: Oct. 20


Benchmarking quantum layout synthesis Computer scientists at the University of California Los Angeles found that current compilers for quantum computers are inhibiting optimal performance and argue that better quantum compilation design could help improve computation speeds up to 45 times. The team designed a family of benchmark quantum circuits with known optimal depths or sizes, which cou... » read more

Week in Review: IoT, Security, Autos


Products/Services Arm released a survey of 650 industry representatives about eSIM and iSIM technology. Ninety percent of the respondents were aware of eSIM, while 43% were unaware of iSIM. Vincent Korstanje, vice president and general manager, Emerging Businesses at Arm, cites the leading three obstacles to large commercial deployments: Resistance from traditional stakeholders (69% of respond... » read more

Will In-Memory Processing Work?


The cost associated with moving data in and out of memory is becoming prohibitive, both in terms of performance and power, and it is being made worse by the data locality in algorithms, which limits the effectiveness of cache. The result is the first serious assault on the von Neumann architecture, which for a computer was simple, scalable and modular. It separated the notion of a computatio... » read more

Power/Performance Bits: July 3


2D straintronics Researchers at the University of Rochester and Xi’an Jiaotong University dug into how 2D materials behave when stretched to push the boundaries of what they can do. "We're opening up a new direction of study," says Stephen Wu, assistant professor of electrical and computer engineering and physics at Rochester. "There's a huge number of 2D materials with different properti... » read more

Power/Performance Bits: Sept. 4


Preventing battery fires Researchers from Oak Ridge National Laboratory and the University of Rochester developed a method to prevent lithium-ion batteries from catching on fire when damaged. "In a lithium-ion battery, a thin piece of plastic separates the two electrodes," said Gabriel Veith, a research lead at ORNL. "If the battery is damaged and the plastic layer fails, the electrodes can... » read more

Mobile Machine Learning Hardware At Arm


Machine learning is playing an increasingly significant role in emerging mobile application domains such as AR/VR, ADAS, etc. Accordingly, hardware architects have designed customized hardware for machine learning algorithms, especially neural networks, to improve compute efficiency. However, machine learning is typically just one processing stage in complex end-to-end applications, which invol... » read more

Manufacturing Bits: Jan. 9


Two-photon lithography Lawrence Livermore National Laboratory (LLNL) has extended the capabilities of a high-resolution 3D printing technique called two-photon lithography (TPL). TPL enables the development of 3D-printed objects. LLNL’s technology could enable 3D-printed embedded structures inside the body, such as stents, joint replacements or bone scaffolds. It could also one day be ... » read more
