塑料也能存储信息吗?(科技大观)

得克萨斯大学研究团队此次在一种塑料分子的低聚物中使用的编码方式,也借鉴了DNA存储的思路。 团队使用4种不同的单体(对应于DNA中的A、T、G、C四种核苷酸),按照一定顺序进行编码,构建 起链状聚合物,随后基于这些分子的电化学性质,对其进行读取解码。具体来说,通过这4种单体的不 同组合构建一个"字符字母表",总共能表示256个不同的字符。为了验证该方法的有效性,研究人员用 这个"字符字母表"合成拥有11个字符密码的链状聚合物,并依据电化学谱学分析对其进行成功解码。由 于每个单体都有独特的电化学信号,因此在逐步降解过程中产生的电信号可以用来解读单体的顺序。 近年来,随着通信技术快速发展,人类社会产生的信息量爆炸式增长,对数据存储的需求与日俱增。除 了光盘、硬盘等传统存储设备外,新型存储介质和存储方式也不断涌现。 前不久,美国得克萨斯大学奥斯汀分校研究团队在国际期刊《化学》上发表研究成果,他们开发了一种 新的信息编码和解码方法,通过合成聚合物分子实现数据存储。这是科学界首次尝试将信息写入塑料, 并使用电信号读取这些信息,这使得在塑料聚合物材料中存储信息成为可能。 我们知道,在分子生物学领域,大分子脱氧核糖核酸(D ...

Core Viewpoint - The article emphasizes the importance of transforming technological innovations into practical productivity through effective financial support and collaboration within the industry, particularly focusing on the Wuhan East Lake High-tech Zone, known as China's "Optics Valley" [1][3]. Group 1: Technological Innovation and Financial Support - The East Lake High-tech Zone is a hub for technological innovation, attracting significant attention from research teams and investors [1][3]. - Zhang Jingyu's research team at Huazhong University of Science and Technology has developed a groundbreaking technology for "massive information low-cost ultra-long-life glass multi-dimensional storage," which has garnered recognition and financial support [5][7]. - The "transfer of shares" mechanism is an innovative investment model that converts initial research funding into equity for future market financing, successfully aiding multiple tech teams in their transition from research to commercialization [7]. Group 2: Entrepreneurial Environment and Growth - Despite not having absolute advantages in industrial support, the East Lake High-tech Zone continues to attract numerous entrepreneurs due to its conducive environment for innovation [8][12]. - The area has nurtured a total of 158,000 innovative enterprises, including 5,821 high-tech companies and 549 gazelle enterprises, showcasing its robust entrepreneurial ecosystem [12]. Group 3: Financial Initiatives and Solutions - In June, the East Lake High-tech Zone launched a "partner program" for tech finance, selecting 400 startup tech companies to form a "seed enterprise database," ensuring 100% credit application response from financial institutions [14]. - The program aims to provide no less than 600 million yuan in annual credit financing, supported by a 30 million yuan risk compensation fund to alleviate banks' lending concerns [14].
