Researchers have made significant strides in developing photodetectors made with tungsten disulfide (WS2) on paper substrates for disposable electronics. This research, which addresses the growing issue of electronic waste, has yielded promising results with WS2 photodetectors on paper substrates reaching photo responses comparable to commercially available silicon photodetectors. The findings have significant implications for ubiquitous electronics and low-performance sensing applications.

Neuromorphic engineering is focused on developing computer hardware and software systems that mimic the structure, function, and behavior of the human brain. The goal of neuromorphic engineering is to create computing systems that are much more energy-efficient, scalable, and adaptive than conventional computer systems, and that can solve complex problems in a manner that is similar to how the brain solves problems. Neuromorphic computing is a specific application of neuromorphic engineering. It involves the use of hardware and software systems that are designed to process information in a manner that is similar to how the human brain processes information.

Spintronics is a technology that utilizes the spin of electrons - in addition to their charge - in order to store and process information. Unlike traditional electronics, which rely on the movement of electrons to perform their functions, spintronics uses the intrinsic angular momentum of electrons to achieve the same results. Spintronics offers the potential to address some limitations of traditional, charge-based computing and it has the potential for developing new types of devices such as spin-based transistors and logic gates.

The extensive use of polymer-made, disposable and non-biodegradable COVID-19 pandemic health protectives like surgical face masks, hand gloves and PPE kits, combined with a lack of proper waste recycling systems, considerably increased plastic pollution around the world. Researchers are harnessing a new way to turn these COVID-19 pandemic wastes towards sensor design by fabricating a mask-glove-based contact-separation triboelectric nanogenerator (MG-CS TENG).

Nanotechnology has the ability to completely transform the health care sector, particularly in developing countries like South Africa, where access to effective healthcare is still a challenge for millions of people living in poverty-stricken environments. Many African countries, despite having policies and strategies in place, struggle to allocate sufficient resources for research in nanomedicine. Most of the research conducted on the subject in Africa is focused on academic interests, rather than practical applications.

Blockchain technology can be used in various ways to improve the transparency, integrity, and security of data in scientific research. For example, it can be used to create a tamper-evident record of research data, facilitate collaborations between researchers, protect intellectual property, fund scientific projects, and track the movement of materials throughout the supply chain. By using blockchain, researchers can ensure that their work is properly credited and cited, and that the data they collect is accurately recorded and preserved for future use.

A new motorized three-point-bending apparatus has been developed that is capable of automating strain engineering experiments on two-dimensional (2D) materials. The setup can be used to apply precise, uniform strain to 2D materials such as MoS2, allowing researchers to study the effects of strain on the electrical and optical properties of these materials. The system can also be used to study straintronic devices, devices whose output characteristics can be adjusted by means of applied strain.
