Silicon Labs (also known as "core technology", NASDAQ: SLAB) has announced the cooperation with Samsung Electronics, for the Internet of Things (IoT) for the edge node battery-powered devices wireless module. The new SAMSUNG ARTIK® 0 module family is based on Silicon Labs' low-power, multi-protocol wireless Gecko System-on-Chip (SoC) with ARM® Cortex ™ -M4 processor. The SAMSUNG ARTIK® 020 module includes the Bluetooth® Low Energy software stack from Silicon Labs and the SAMSUNG ARTIK® 030 module uses Silicon Labs' ZigBee® and Thread ™ mesh networking stacks. These small form-factor modules (13 mm x 15 mm) are ideal for space-constrained applications, incorporating all the necessary components, including the antenna, to simplify the RF design process. The SAMSUNG ARTIK platform is a fully integrated silicon-to-cloud solution that helps IoT developers accelerate their product development, reduce time-to-market, and lower the total cost of ownership of their IoT products. In addition, the SAMSUNG ARTIK platform provides world-class security from device-to-center to cloud and data management. Curtis Sasaki, vice president of ecosystems at Samsung Strategy and Innovation Center, said: "As a leader in IoT connectivity technology, Silicon Labs is an important partner for our new SAMSUNG ARTIK 0 series of modules, and Silicon Labs' advanced wireless SoC technology supports Bluetooth, ZigBee Connecting to Thread provides the ideal solution for the IoT peripheral node market and connects with other Samsung optimized modules for data concentration and Samsung ARTIK Cloud. " The SAMSUNG ARTIK platform provides the necessary hardware, software, tools and building blocks for SAMSUNG ARTIK Cloud for the development of new enterprise, industrial and consumer applications. Developers can focus on designing new applications and services instead of building an entire system from scratch, speeding time to market. Dennis Natale, vice president of business development for Silicon Labs's IoT, said: "Silicon Labs is pleased to work with Samsung to develop the latest and highest quality wireless modules that enable developers to accelerate the delivery of secure, interoperable and intelligent IoT products and services We were impressed with the rapid growth of the Samsung ARTIK platform ecosystem as the first certified partner of the Samsung ARTIK module and we are excited about the future opportunities and we look forward to assisting Samsung in its vision of providing A powerful horizontal IoT platform that includes all the hardware, software, security and cloud-based technologies needed to meet a diverse customer base.

Duplex Stainless Steel Overview
Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.
Today, modern duplex stainless steels can be divided into three groups:
Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
