June 3, 2021 – Penicillin, the microwave oven, Viagra, and chocolate chip cookies were all successful accidental accomplishments. Joining these is one-dimensional (1D) atomic silver wire. Eluding scientists for two decades, this milestone in nanotechnology was achieved by an international team of researchers who were trying to do something else.

 Researchers from Fudan University in Shanghai, Japan’s National Institute for Materials Science, and Queensland University of Technology’s (QUT) Centre for Materials Science were examining the properties of silver by putting silver atoms on the outside of manganese dioxide nanorods that had channels inside them. The scientists conducted the experiment in regular air, rather than inside an inert vacuum, expecting the silver atoms to react with oxygen and form silver oxide.

 Instead, the silver atoms diffused quickly inside the nanorod channels in a self-assembly technique that formed 1D silver rods up to 1 μm in length that was stable outside a vacuum. The team made 200 silver wires as wide as one atom. In an article at ZDnet, QUT professor Dmitri Golberg said that unexpectedly, the silver demonstrated a temperature-controlled insulator-to-metal transition. This means that depending on the temperature, the wire could be used as a switch in thermal electrical devices. If the wires are processed at suitable 3D sizes, which is still a challenging endeavor, they could be connected to nanocircuitry. Ultimately, the atomic wire discovery could contribute to the manufacture of electronic devices on a molecular scale. The study was published in the journal Nature Communications.

6/3/2021: UL has recognized four new Halguard® low-smoke, flame retardant jacketing compounds as “halogen-free”, it was announced today by Teknor Apex Company. The compounds include new-generation EVA-based products with an enhanced balance of properties, and highly flexible TPE-based products that exhibit excellent oil and sunlight resistance.

The assessment of halogen content was conducted in accordance with UL 2885 standard for the presence of fluorine (F), chlorine (Cl), bromine (Br) and iodine (I) at a maximum individual limit of 1,000 ppm. With the four new grades, there are now fifteen Halguard low-smoke, halogen-free flame retardant (LS-HFFR) compounds with UL AATJ2 component recognition as Halogen-free.

The new compounds, all with UL 94 flame ratings of V-0, are of two types:

● EVA-based compounds for control, data, and transit cables. Halguard grades 58240 and 58242 provide high levels of flame retardance, resistance to heat shock and heat deformation, and ease of processing —the latter translating into increased throughput. The compounds enable cables to comply with UL 1685-FT4/IEEE 1202 standards for vertical tray cable and the UL 1666 standard for riser cable. Other applications include fiber optic data cables and cables used in transit infrastructure, as in the case of tunnels.

● Highly flexible, oil- and sunlight-resistant TPE-based compounds. Incorporating elastomers, these two products comply with UL 62 and UL 758 standards for flexible cord and appliance wire, respectively. Halguard E 59001 exhibits 80% and 90% retention of tensile strength and elongation at break, respectively, upon immersion in IRM 902 oil for seven days at 60 °C. Halguard E 59002 retains 90% and 95% of tensile strength and elongation at break upon exposure for 720 hours in a weatherometer.

Typical property data for these compounds appear in the accompanying table.

“The Halguard LS-HFFR product line provides properties to meet a wide range of applications, and the growing list of grades with ‘halogen-free’ assessments by UL further expands options for customers,” said David Braun, wire and cable industry manager for the Vinyl Division of Teknor Apex. “We will continue to develop Halguard compounds which can comply with this UL assessment in order to provide customers with readily available component recognition, which enables them to accelerate speed to market for their products.

Halguard LS-HFFR compounds are available worldwide.

7/7/2021: DtGV, the German Association for Consumer Studies, has named SIKORA as one of the winners of its SME Innovation Award 2021/2022.

A press release said that the award goes to small and medium-sized companies from Germany “that demonstrate particularly high innovation potential in their segment and/or state.” The award was based on the Corporate Patent Classification (CPC) system. The basic parameter patent number was rounded off by the qualitative moment of the citation frequency and condensed into a score value.

SIKORA, a supplier of measuring technology, was scored as being among the top 10% of all examined SMEs in the CPC main class for instruments.” In the parallel federal state ranking, it was listed as one of the top three companies from Bremen. “This award makes us very proud and confirms the corporate course we have been following since the foundation of the company,” said Sikora CEO Dr. Christian Frank. “Thanks to our inventive spirit and innovation potential, we are able to continuously offer our customers future-oriented technology solutions. Thus, we create the basis for highest customer satisfaction and long-term growth.”




June 3, 2021 – South Korea’s Kyungshin Group has officially opened its new production operation that will produce battery components for high-tech electric vehicles, in the Guberash industrial zone of Smederevska Palanka in Serbia.

The website for the Kyungshin Group, which supplies the auto industry, notes that customers include Hyundai and Kia. It also has production facilities in China, India, Honduras and Poland. Among those attending the grand opening ceremony was Serbian President Aleksandar Vucic. Per the Development Agency of Serbia RAS at the company’s website, Kyungshin Cable Europe will supply the European market, and create 700 new jobs by the end of 2022.

Kyungshin Cable Europe is part of the Kyungshin Group, which also has facilities in the U.S., Mexico, China, Poland and South Korea. Founded in 1974, Kyungshin Cable’s core activity has been expanded from automotive and industrial wires and cables to the production of car parts for high- and low-voltage electric vehicles, in accordance with the new trends in the automotive industry.

June 3, 2021 – The next staging of wire Southeast Asia—and its sister show, Tube Southeast Asia—will now be held Feb. 9-11, 2022 at the Bangkok International Trade & Exhibition Centre (BITEC) in Bangkok, Thailand.

A press release from organizers Messe Düsseldorf said that the event, which was to be held Sept. 22-24, is being moved to the new dates to “allow for optimum international participation.” It noted that in the past, over 90% of the exhibitors came from overseas countries such as Austria, France, Germany, Great Britain, India, Japan and Korea. “It is anticipated that by next year with further easing of travel restrictions and ongoing successful vaccine deployments worldwide, there will be a more optimistic environment for companies to do business safely and effectively at these trade fairs.”

The two trade fairs were first held in 1997. At the last staging in 2019, international exhibitors from 29 countries participated at the trade fairs, while 45% of trade visitors came from outside Thailand.
