Chinese scientists have achieved low-cost preparation of deuterated acids and bases, which is expected to be applied in luminescent materials such as OLEDs.

Core Tip: According to the Chinese Academy of Sciences, recently, Professor Xu Tongwen, Distinguished Professor Wang Yaoming, and Professor Li Zhenyu's team from the National Key Laboratory of Precision Intelligent Chemistry at the University of Science and Technology of China have made breakthrough progress in the preparation of deuterated chemicals. The team innovatively utilized bipolar membranes to achieve efficient dissociation of heavy water (D2O), revealing for the first time the phenomenon where the migration rate of deuterium ions (D+) surpasses that of hydrogen ions (H+), overturning the traditional understanding that "the dissociation rate of heavy water is slow," and developed a new technology for the low-cost and high-efficiency preparation of deuterated acids and deuterated bases.

Is USB 4 really the latest version of USB?

The newly released USB4 connector specification is mainly used for high-speed data transmission in automated systems. However, USB3.2 products will first appear on the market. The USB3.2 connector will start appearing in various devices in the coming months. The latest USB standard announced at the end of 2017 has not yet made its debut, and suddenly, USB3.2 is no longer the latest USB standard. USB4 has emerged. In March 2019, the USB Implementers Forum announced that the USB4 specification would be released in mid-2019. However, we will need at least another year to see it.

5G networks require higher standards for cables and connectors.

The new generation of optical fiber cables and high-speed connection products is laying a solid foundation for the comprehensive implementation of 5G networks. Suppliers of optical fiber cables, high-speed connectors, and cable management systems are preparing to meet the challenges brought by the full deployment of 5G network infrastructure. The arrival of 5G networks has had a significant impact on these key components, especially the connectors and cables used in wireless and wired infrastructure. Recently, the United States and the United Kingdom announced the acceleration of 5G network development, injecting vitality into the entire network industry. Today, Western economies are trying to compete with the 5G technology launched by China.

The new RoHS directive adds four substances, significantly impacting plastic products.

Phthalates will be restricted in EU countries starting in July. This directive will affect various plastic electronic products such as connectors. The EU's Restriction of Hazardous Substances (RoHS) environmental compliance directive is expanding its scope. In 2019, four new substances were added to the list of prohibited electronic materials in Europe: di(2-ethylhexyl) phthalate (DEHP), butyl benzyl phthalate (BBP), dibutyl phthalate (DBP), and diisobutyl phthalate (DIBP). These phthalates restrict most electrical and electronic equipment (EEE) under RoHS.

HDMI 2.1 will drive the popularity of the fiber optic HDMI market.

Entering 2019, it was found that 4K had already become a common product, followed closely by the beginning of the popularization of 8K and 10K. The bandwidth of HDMI has also progressed from the initial version 1.4's 10.2G to version 2.0's 18G, and now to HDMI version 2.1's 48G. It can be said that it has made rapid progress. Today, let's talk about how HDMI 2.1 will drive the popularization of the fiber HDMI market. The bandwidth of HDMI 2.1 has surged from HDMI 2.0b's 18Gbps to 48Gbps, fully supporting 4K@120Hz and 8K@100/120.

The changes in HDMI 1.0 to HDMI 2.1 specifications you must understand [2018]

The development of a standard from its inception to maturity is far from a one-day effort, especially in the market for consumer products. Therefore, when purchasing products, everyone must carefully check the changes in versions, including televisions, cable TV set-top boxes, streaming media players, and other home theater equipment. We are still in the 4K era, and the minimum interface should be compatible with HDMI 2.0 products; otherwise, you will regret it! The upgrade cycle of consumer products is indeed very fast nowadays! Let's talk about the changes in specifications from HDMI 1.0 to HDMI 2.1. The world's first Blu-
