NCA's Staff is Critical to its Success


Aylesbury, Buckinghamshire, UK — Nordson DAGE, a division of Nord- son Corporation, recently launched a compact, fast and light X-ray inspec- tion system — Explorer™ one. This inspection system includes a propri- etary, pioneering, lead-free shielding technology called EnviroShield™. Lead is a versatile material which is still used for a wide range of


applications, including radiation


shielding in X-ray inspection equip- ment. However, lead is also a partic- ularly toxic material and there are now many initiatives in place to min- imize its use and reduce the likeli- hood of it entering the environment where it can contaminate the food chain.


Nordson DAGE is committed to


protecting the environment. During development of the new Explorer one X-ray inspection tool, the company saw an opportunity to make a funda- mental change for the better and de- veloped EnviroShield. EnviroShield is a new, propri-


etary (patent pending), lead-free X- ray shielding technology, which the company uses instead of lead during the manufacturing of Explorer one. The company’s goal is to divert hun- dreds of tons of lead from being used in the future. Designed specifically for the


electronics industry, using Nordson DAGE’s unique integrated technolo- gy, the machine has proven to be an exciting new product since its launch in May 2019. Market-leading image

Graphite May Be the Key to Longer Battery Life


Kazan, Russia — The beginning of this project dates back to 2012 and 2013, when Aryat Dimiev was work- ing at Rice University in Houston, Texas, with professor James Tour. They discovered a phenomenon that could be observed by optical micro- scopes, during the stage transitions of graphite intercalation compounds. It took Dimiev six years to fully com- prehend the driving forces behind the observed phenomena. An impor- tant breakthrough came from the use of new and unique equipment, manufactured by SOL instruments, which allowed ultra-fast Raman


mapping of the graphite surface dur- ing the stage transitions. Graphite intercalation com-


pounds (GICs) are formed by inser- tion of certain atomic and molecular species between the graphene layers of graphite. The resulting com- pounds possess a range of unique properties, which are not specific to the parent materials. Among the most intriguing


properties of GIC is its superconduc- tivity, a discovery that triggered much interest. Depending on the electrochemi-


cal potential of the intercalant, and the respective charge on the graph - ene layers, graphite forms structures where one, two or more graphene layers are sandwiched between the two layers of intercalant. The result- ing compounds are referred to as stage-1, stage-2, and stage-3 GICs, respectively. Despite intensive and long-lasting research into GICs, the mechanism of the stage transitions remains obscure.

Coherent Signals in Silicon Chips May Lead to


Quantum Tsukuba, Japan — From home PCs to business servers, computers are a central part of our everyday life, and their power continues to grow at an astounding rate. However, there are two big problems looking on the hori- zon for classical computers. The first is a fundamental limit


on how many transistors we can pack into a single processor. Eventually a totally new approach will be needed if we are to continue to increase their processing capacity. The second is that even the most powerful comput- ers struggle with certain important problems, such as the cryptographic algorithms that keep our credit card numbers safe on the internet, or the optimization of routes for delivering packages. A team at the University of


Tsukuba studied a novel process for creating coherent lattice waves in- side silicon crystals using ultra-short laser pulses. Using theoretical calcu- lations, combined with experimental results that were obtained at the University of Pittsburgh, they were able to show that coherent vibra- tional signals could be maintained
