Transistor Promises Faster, More Energy-Efficient Operation

A new type of transistor is in the works inside a US campus laboratory. It is resilient and super-fast but, for now, it is still a work in progress.

A new transistor in development inside a Massachusetts laboratory is said to be extremely tough and resilient and offer super-fast switching, while meeting - or even exceeding - industry standards.

Researchers at MIT first announced the transistor's development in 2021 when they published the results of their study which explored the use of an ultra-thin ferroelectric material made from boron nitride. At that time the report was carried in the journal, Science, researchers wrote only of the possibilities.

Now it is a reality. Working inside the laboratory, the scientists created that faster, more energy-efficient transistor and they claim that even after 100 billion switches, there are no signs of degradation. Researchers told Popular Mechanics magazine that, for electronic devices such as computers, this eliminates the need for selective storage on a chip. Scientists also say that boron nitride has another advantage: it remains stable over long periods of time because its polarization can be reversed when there is an electric field.

The next reality - actually manufacturing it - could be a lot tougher. Scientists acknowledged that despite the great gains in this development, they still don't have a way to mass produce it.

Solar Cycle 25 Producing Record High Sunspot Numbers

Solar Cycle 25 Producing Record High Sunspot Numbers

Record High Solar Cycle 25 Solar Maximum Sunspot Numbers Have Improved HF Propagation Since Mid-July and Possibly Bringing Worldwide 6 Meter F2 Propagation This Fall.

According to the NOAA Space Weather Prediction Centre (SWPC), Solar Cycle 25 likely reached its highest sunspot number yet of at least 299 on 8th August 2024.

The World Data Centre - Sunspot Index and Long-Term Solar Observations (SILSO) publishes near-real-time Estimated International Sunspot Number (EISN) reports based on its global network of reporting stations. Daily EISN reports during Solar Cycle 25 were consistently well below 200 until suddenly rising to 218 on 14th July and reaching 289 on July 18th, but then declining to 178 on 22nd July 2024.

New York High School Helps License Amateur Radio Operators

New York High School Helps License Amateur Radio Operators

On 1st August 2024, Steve Goodgame, K5ATA, ARRL Education and Learning Manager, took a train trip to New York City to visit the Staten Island Technical High School. He was there to help administer amateur radio exams to 49 students and all passed their exams. Several upgraded their licenses from General to Extra class and two students went from unlicensed to Extra class in one sitting.

Their teacher, Everton Henriques, KD2ZZT, attended ARRL’s Teachers Institute on Wireless Technology TI - 1 last year and TI - 2 this year. Since then, Everton has helped over 100 kids successfully test for their amateur radio licenses. He has built a program incorporating HF, local repeater use, foxhunting, and space communications and has plans to incorporate mesh networking with his students this coming school year.
