1.8g of SiC requires about 177 kW / h of energy. Researchers have proposed a new way of turning plants into a valuable industrial material called silicon carbide (SiC). In a new study, scientists at the Salk Institute (USA) have converted tobacco and corn husks into SiC. These findings are critical to help researchers evaluate and quantify carbon uptake strategies. “The study gives a very careful calculation of how this valuable substance is made and how many carbon atoms are removed from the atmosphere,” said study co-author Professor Joseph Noel of the Salk Institute. SiC is also known as carborundum. This is a super hard material used in ceramics, sandpaper, semiconductors, and LEDs. Salk’s team used a previously reported method to convert plant materials into SiC in three stages. First, the researchers planted tobacco plants from seeds, which were selected for the short growing season. They then pulverized the harvested plants and treated it with a number of chemicals, including silicon-containing compounds. In the final stage, the starch plants are turned into rocks to give SiC. This process involves heating the material to 1,600 degrees Celsius. “We have demonstrated that carbon can be isolated from agricultural residues such as corn husks,” said study author Suzanne Thomas. Thereby, a green material is created ”. Through elemental analysis of plant meal, the authors measured a 50,000-fold increase in carbon sequestration from seed to laboratory plants. This is a demonstration of the effectiveness of plants in reducing atmospheric carbon. When heated to high temperatures to freeze, the plant material loses some of its carbon as a variety of decomposition products. The researchers calculated that the generation of 1.8 g of SiC requires about 177 kW / h of energy. Most of the energy (70%) is used at the freezing step. The current SiC manufacturing process has comparable energy costs, the authors note. Therefore, the team thinks that new technologies produced by renewable energy companies could reduce energy costs. In the future, the team expressed hope to explore this process in a variety of plants, especially species such as horsetail or bamboo. These are species that contain large amounts of natural silicon.

Ms. Do Thu Trang, Marketing Manager of Newway Company, said that this is the 8th time that Newway has participated in the exhibition. Here, Newway introduces new products, specializing in inkjet printing, which are manual printers with high technical requirements. Modern packaging printing technology of SIC Printing Import-Export Joint Stock Company at VPSE 2021 “We participate in exhibitions every year because we see the positive effects it brings. After each exhibition, the number of our partners and customers from all regions increases. This is a fairly effective investment attraction. I hope businesses in the field of printing and advertising will have many opportunities to cooperate at home and abroad, attracting investment in Hanoi in this field ”, emphasized Ms. Thu Trang. In the framework of the International Exhibition of Machinery and Equipment for the printing, packaging and printing industry of Vietnam labels (VPSE 2021), SIC Printing Import and Export Joint Stock Company also exhibited a huge booth including products and modern printer line. Mr. Nguyen Duc Dung, Sales Manager of SIC said that the company has participated in the 3rd VPSE 2021 exhibition. Through the exhibition, SIC has attracted many interested customers and partners. According to Mr. Dung, the trend of using paper packaging has been very developed in recent years, so this is an opportunity for companies to find a satisfied partner. Since participating in the exhibition, the company has developed many new customers, usually after each exhibition there will be at least 30 customers / partners from all over the provinces, creating many opportunities for business cooperation. and attract customers to the Hanoi packaging advertising industry. Ms. Do Thu Trang, Marketing Manager of Newway Company: “This is a fairly effective investment attraction” Present at a large showroom with the most modern 2-sided printer technology today, Mr. Tran Long, Deputy Technical Department, sales specialist of 3-domain printing advertising and commercial limited liability company said, This is the third time the company has participated in the International Exhibition of Advertising Equipment and Technology in Hanoi. After each participation, the number of customers and partners increased by 30%, the brand also “exploded” more, especially in the field of providing advertising materials. “The exhibition has opened up opportunities for Hanoi businesses to a business exchange environment, attracting investment from provinces. In addition, many advertising companies in the provinces and cities, although not participating in the exhibition, but through the spread of the media, they realize that this is a prestigious playground so they come to trade. I hope more and more domestic and foreign partners visiting this exhibition will cooperate with Hanoi enterprises ”, Mr. Tran Long shared. Mr. Tran Long: “I hope more and more domestic and foreign partners visiting this exhibition will cooperate with Hanoi enterprises” According to Mr. Nguyen Thanh Dao, General Director of Southeast Trade Promotion and Advertising Joint Stock Company, after 8 years of establishment, development and 3 years of affirming its role in the North, VietAd Exhibition has become important events not to be missed by the advertising industry business community. This is a place to trade, meet, exchange experiences as well as open up new cooperation opportunities for businesses in the advertising industry. Starting in 2017, VietAd Exhibition was organized at the same time the International Exhibition of Machinery and Equipment for printing packaging industry, printing Vietnamese labels, VPSE. With the support and sponsorship of the Ministry of Culture, Sports and Tourism, the Ministry of Industry and Trade, the Ministry of Information and Communications; was chaired by the Vietnam Advertising Association and Hanoi Advertising Association with more than 1,000 booths of more than 250 participating enterprises. Two-sided printers operating at the show This year VietAd Hanoi focuses on introducing many advanced machines, equipment and technologies of the advertising industry, including many areas such as the display of advertising machinery: Digital inkjet printers, UV printers, printers Heat transfer, heat press, CNC engraving machine, laser cutter, fiber cutter, multifunctional color photocopy machine, Led technology, equipment, advertising materials: ink, decal, mica, hiflex, glue, PP , standee, advertising screen … VietAd Hanoi Exhibition has become an important event that cannot be ignored of the Vietnamese advertising business community. This is a place to trade, meet, exchange experiences as well as open up new cooperation opportunities for businesses in the advertising industry.
