This chip has speed that defies the light speed barrier while maintaining cool temperatures using a special metamaterial that allows the light particles to go infinitely fast.
Most metamaterial experiments occur in bulk transmission geometries. Here researchers demonstrate integrated in-plane zero-index metamaterials.
A new computer simulation of how our brains develop and grow neurons has been built by scientists from the University of Surrey. Along with improving our understanding of how the brain works, researchers hope that the models will contribute to neurodegenerative disease research and, someday, stem cell research that helps regenerate brain tissue.
After thousands of years as a highly valuable commodity, silk continues to surprise. Now it may help usher in a whole new direction for microelectronics and computing.
While silk protein has been deployed in designer electronics, its use is currently limited in part because silk fibers are a messy tangle of spaghetti-like strands.
The edible transistor is based on an existing transistor architecture, utilizing CuPc as the active material. The key component, the electrolyte-gated OFET (EGOFET), operates at low voltages (1 V) and can function stably for more than a year. The transistor showed good reproducibility, with performance characteristics that pave the way for integrating these devices into more complex edible circuits.
The circuits are constructed on a derivative of cellulose with electrical contacts being printed using inkjet technology and a solution of gold particles (which are also commonly used in the food industry for decoration). The transistor “gate” is also food-grade. This component controls the flow of electrical current between the source and drain terminals, effectively acting as a switch or amplifier. This gate is made from a gel based on chitosan another food-grade ingredient used as a gelling agent.
The research team also explored the optical and morphological properties of CuPc thin films. They found that the thickness of the CuPc layer played a crucial role in the transistor’s performance. Thinner films displayed better charge transport properties, which are essential for creating high-performing, low-voltage devices. This detailed understanding of the material’s properties allowed the team to optimize the transistor’s design for use in real-world applications.
According to a recent article published on the Vietnam Government News website, on September 21, Prime Minister Pham Minh signed Decision No. 1018/QD-TTg, issuing Vietnam’s strategy and vision for the development of the semiconductor industry, with short-term goals until 2030 and long-term projections until 2050.
In this strategic plan, Vietnam outlined five specific tasks and measures, including: Developing specialized chips; Promoting the development of the electronics industry; Developing human resources and attracting talent in the semiconductor field; Attracting investment in the semiconductor sector; and Other relevant tasks and measures.
Goals for 2050: 3 Manufacturing Plants, 20 Packaging and Testing Facilities Overall, this strategy aims to develop Vietnam’s semiconductor industry through a three-phase roadmap.
The monolithic 3D integration of 2D molybdenum disulfide memtransistors and graphene chemitransistors can be used to create near-sensor computing chips with high interconnect density and a vertical separation between tiers of less than 50 nm.
Quantum computers and quantum communication are groundbreaking technologies that enable faster and more secure data processing and transmission compared to traditional computers. In quantum computers, qubits serve as the fundamental units of information, functioning as the quantum mechanical equivalent of bits in classical computing.
Where, for example, laser pulses in a glass fiber transport information from A to B in classical digital communication, quantum mechanics uses individual photons. In principle, this makes it impossible to intercept the transmitted data. Qubits that are optically addressable (can be controlled or read out with light) are suitable for storing the photons’ information and processing it in quantum computers. The qubits can store and process quantum states, and absorb and emit them in the form of photons.
Helene shut down the Spruce Pine mines that produce ultra-pure quartz, and some fear that could cause shortages and higher prices on things we buy.
So, how likely is that to happen?
The good news is Sibelco, Spruce Pine’s largest quartz mine, says its employees and contractors are all safe and accounted for.
