An international research team has developed a new technology for the manufacture of high quality transistors from 2D materials, which significantly reduces the cost of their production..
Scientists have demonstrated that lithography using a probe heated above 100 °C, has surpassed standard methods for making metal electrodes on 2D semiconductors. These transition materials could potentially replace silicon in the atomic chips of the future. The proposed method, called thermal scanning probe lithography (t-SPL), has several advantages over modern alternatives..
First of all, the new technology significantly improves the quality of 2D transistors by removing the Schottky barrier, which prevents the flow of electrons at the interface between the metal and the 2D substrate. In addition, unlike electron beam lithography, t-SPL allows chip designers to easily apply electrode patterns.
The new method helps to significantly reduce production costs because it does not require special environmental conditions and does not consume as much energy as electron beam lithography. Therefore, it can be used much easier on an industrial scale..

Scientists hope the technology will be integrated into 3D printers equipped with nanoscale tools in the future. In fact, such plans could very well be realized as 3D printing technologies are now rapidly improving. Recently, a team of engineers introduced a method for 3D printing intelligent piezoelectric materials.
Boston Dynamics has developed a humanoid robot Atlas, which deftly overcomes obstacle courses, demonstrating elements of parkour.
The tech company has posted a short video in which the new bipedal robot demonstrates prowess as it climbs to the top of the towering boxes. For several years, engineers from Massachusetts have been creating automated mechanisms with unique capabilities, but now they are close to developing not a simple assistant, but a potential combat system..
Previous creations of Boston Dynamics are capable of doing back flips, opening and holding doors, washing dishes, overcoming obstacles, and now parkour elements have been added to this list. In the process of movement, to mobilize energy, Atlas uses its torso and limbs for jumps of 40 cm, and is oriented using computer vision, which makes it possible to identify surrounding objects.
Such decisions can generate interest from military technology agencies, law enforcement agencies and the entertainment industry. With partial revision, it will be able to solve various tactical tasks.
Ford is developing an equally unique vehicle control system. According to the patent, the company plans to create a mobile application with which the driver can control the unmanned vehicle, like in a video game..

How to Secure the IoT with Blockchain @ [IoT World 2020]
Gemalto, one of the world's largest digital security companies, found that blockchain use cases for securing IoT devices increased from 9% to 19% over the past 12 months..
IN document it is said that implementation is growing even though there is no regulation in this area. Gemalto surveyed 950 IT professionals and managers around the world. 23% of respondents named blockchain as an ideal solution for protecting IoT, and 91% of companies that do not yet use technology in their activities are inclined to do this in the future.
According to researchers, 52% of enterprises are unable to determine if the security of the Internet of Things (IoT) is compromised, even as costs and focus on protecting digital devices rise. Gemalto predicts that the IoT network will exceed 20 billion nodes by 2023, therefore recommends companies not tighten with improving their threat detection systems.
Analysts also note that despite the growth in blockchain adoption, adoption rates are low as businesses continue to rely on other ways to protect. In 71% of cases, this is data encryption, 66% use passwords for this, 38% implement two-factor identification systems.
Jason Hart, CTO of Gemalto's data protection, says businesses clearly feel the need to protect the growing amount of information they accumulate. However, despite investments in technologies security, such as blockchain, they need additional guarantees from regulators. Therefore, business must put pressure on the government, because in the end it is he who will suffer the most from hacks..
