Scaling behavior of InAlN/GaN HEMTs on silicon for RF applications

Due to the low cost and the scaling capability of Si substrate, InAlN/GaN high-electron-mobility transistors (HEMTs) on silicon substrate have attracted more and more attentions. In this paper, a high-performance 50-nm-gate-length InAlN/GaN HEMT on Si with a high on/off current (Ion/Ioff) ratio of 7.28"‰Ã—"‰106, an average subthreshold swing (SS) of 72 mV/dec, a low drain-induced barrier lowing (DIBL) of 88 mV, an off-state three-terminal breakdown voltage (BVds) of 36 V, a current/power gain cutoff frequency (fT/fmax) of 140/215 GHz, and a Johnson's figure-of-merit (JFOM) of 5.04 THz V is simultaneously demonstrated. The device extrinsic and intrinsic parameters are extracted using equivalent circuit model, which is verified by the good agreement between simulated and measured S-parameter values. Then the scaling behavior of InAlN/GaN HEMTs on Si is predicted using the extracted extrinsic and intrinsic parameters of devices with different gate lengths (Lg). It presents that a fT/fmax of 230/327 GHz can be achieved when Lg scales down to 20 nm with the technology developed in the study, and an improved fT/fmax of 320/535 GHz can be achieved on a 20-nm-gate-length InAlN/GaN HEMT with regrown ohmic contact technology and 30% decreased parasitic capacitance. This study confirms the feasibility of further improvement of InAlN/GaN HEMTs on Si for RF applications.

The True Value of Human-Centered Research Within Medical Technology

With recent statistics suggesting that 70% of all projects fail, it’s vital that we do all we can to set ourselves up for success when we set out on a new design or development of a product. Every day, we are surrounded by products and services that don’t work as we expect them to. Whether it is a hard-to-follow set of instructions for a new medical device or a convoluted setup process, people are constantly forced to develop workarounds to compensate for poor design.

Periodical propagation of torsion in polymer gels

Gel actuators have potential in soft robotics. Although gel actuators can realize various motions like contraction, expansion, and bending, most require external inputs such as batteries and circuits. Herein we propose a periodical torsional motion hydrogel driven by chemical energy from the Belousov-Zhabotinsky (BZ) reaction. Our BZ gel system exhibits autonomous motion without a battery. The elastic moduli of the redox states of the BZ gel are investigated using stress"“strain analysis. An experimental system, which integrates the BZ gel and two PDMS (dimethylpolysiloxane) rotators, is designed to evaluate torsion angles. The experimental pre-twist angle dependence of the rotary motion is compared with a theoretical rotation model. The results agree qualitatively. This study should contribute to the development of soft actuators without external components.

An autonomous portable platform for universal chemical synthesis

Robotic systems for synthetic chemistry are becoming more common, but they are expensive, fixed to a narrow set of reactions, and must be used within a complex laboratory environment. A portable system that could synthesize known molecules anywhere, on demand, and in a fully automated way, could revolutionize access to important molecules. Here we present a portable suitcase-sized chemical synthesis platform containing all the modules required for synthesis and purification. The system uses a chemical programming language coupled to a digital reactor generator to produce reactors and executable protocols based on text-based literature syntheses. Simultaneously, the platform generates a reaction pressure fingerprint, used to monitor processes within the reactors and remotely perform a protocol quality control. We demonstrate the system by synthesizing five small organic molecules, four oligopeptides and four oligonucleotides, in good yields and purities, with a total of 24,936 base steps executed over 329"‰h of platform runtime.

Gather AI Raises $10M Series A to Deliver Real-Time Inventory Visibility to the Supply Chain

Industry-First Real-Time Inventory Visibility Platform Using Autonomous Commercial Drones, Maximizing Efficiency and Revenue while Driving Down Costs and Frustration. Gather AI, a supply chain robotics company, announced a $10 million Series A financing round led by Tribeca Venture Partners, with participation from existing investors Xplorer Capital, Dundee Venture Capital, Expa, Bling Capital, XRC Labs and 99 tartans. This latest funding accelerates Gather AI’s go-to-market strategy and continued development of their leading real-time inventory visibility platform. The platform uses off-the-shelf autonomous drones, paired with sophisticated AI-driven software, to solve the problem of misplaced inventory in warehouses – a problem that is the source of an estimated $150B annual loss that heavily impacts manufacturers, warehouse operators, and consumers.

The Importance of Preventative Maintenance for Lab Equipment

Originally Posted On: The Importance of Preventative Maintenance for Lab Equipment. In 2012, billions of dollars and over a decade of ground-breaking Autism research was lost when a freezer malfunctioned at a Harvard-affiliated research center. The freezer held 150 brains, one third of which made up the world’s largest collection of Autism brain samples. As brain samples are extremely difficult and expensive to acquire and maintain, Autism researchers are still making up for the lost samples a decade later. The root of the malfunction was clear- the freezer had not been regularly serviced for preventative maintenance. Unfortunately, when preventative maintenance measures are not routinely performed on lab equipment, these catastrophic losses are not uncommon. Luckily, MarathonLS can support your lab’s preventative maintenance needs.

AI Ethics And AI Law Are Moving Toward Standards That Explicitly Identify And Manage AI Biases

It is not a game that you would normally willingly undertake. Here’s why. Someone offers to you that it is an allegedly fun sport and if you take the sweet bait they then toss an entire deck of playing cards into the air and summarily onto the floor. The person then gives you a cheeky smile and tells you to go ahead and pick up the cards. That’s the entire game.
