DGIST Professor Yoonkyu Lee’s research team used intense light on the surface of a copper wire to synthesize graphene, thereby increasing the production rate and lowering the production cost of the high-quality transparent-flexible electrode materials and consequently enabling its mass production. The results were published in the February 23 issue of Nano Energy.

This technology is applicable to various 2D materials, and its applicability can be extended to the synthesis of various metal-2D material nanowires.

The research team used copper-graphene nanowires to implement high-performance transparent-flexible electronic devices such as transparent-flexible electrodes, transparent supercapacitors and transparent heaters and to thereby demonstrate the commercial viability of this material.

Silver, gold and copper nanowires are leading contenders for next-generation nanoscale devices, however greater understanding of how they work and improved production methods are needed before they can be widely used, explains a recent review in the journal Science and Technology of Advanced Materials.

“Metal nanowires are used for numerous applications, but our understanding of their mechanical properties remains elusive,” says Nurul Akmal Che Lah, engineer at Universiti Malaysia Pahang.

Lah and colleague Sonia Trigueros at the University of Oxford reviewed methods for synthesising and analysing silver, gold and copper nanowires for molecular-based electronics.

Small interfering RNAs (siRNAs) are novel therapeutics that can be used to treat a wide range of diseases. This has led to a growing demand for selective, efficient, and safe ways of delivering siRNA in cells. Now, in a cooperation between the Universities of Amsterdam and Leiden, researchers have developed dedicated molecular nanocages for siRNA delivery. In a paper just out in the journal Chem they present nanocages that are easy to prepare and display tunable siRNA delivery characteristics.

The nanocages were developed in the research group for Homogeneous, Supramolecular and Bio-inspired catalysis of Prof. Joost Reek and Bas de Bruin at the University of Amsterdam’s Van ‘t Hoff Institute for Molecular Sciences, and further studies in the group Prof. Alexander Kros at the Leiden Institute of Chemistry.

The researchers were motivated by the potential of siRNA in gene therapy, which requires the need for effective delivery systems. They set out to develop nanocages with functional groups at the outside, making the cages capable of binding siRNA strands. As the binding is based on reversible bonds, the siRNA can in principle be released in a cellular environment. To explore the delivery characteristics of their nanocages, the researchers performed a laboratory study using various human cancer cells.

Wearable devices like Spiderman’s suit that are thin and soft, yet also feature electrical and optical functionalities? The answer lies in producing novel materials that go far beyond the performance of existing materials and developing technology that enables the precise control of the physical properties of such materials.

Separating transition metal dichalcogenide (TMD) into a single layer just like graphene makes it transform into a thin, two-dimensional (2D) film material that exhibits the characteristics of highly performing semiconductors. By stacking two disparate TMD layers, different combinations of TMD types and stacking methods can produce unique properties.

For this reason, 2D semiconductors based on heterostructures are attracting attention as an important next-generation material for the electronics industry throughout academia and industries around the world. However, it is still quite challenging to commercialize them due to the difficulty of controlling with precision the physical properties of their quasiparticles.

After a few weeks of hard work and dedication, Cyberlife is now completely available to the public. This new webzine will be primarily focused on showcasing the culture of transhumanism, a philosophical and scientific movement that has been gaining momentum over the past few years. Here, you can turn your brain off for an hour at a time to read about the newest trends, listen to music, and admire the artistic talent of our staff members. We are still looking for more people to contribute, so here is a short list of what we are looking for:

Literature: Cyberlife does support the literary arts and this is how we do it. If you have some random short stories lying around that you have never published, submit them to us. We would love to read some short fiction that relates to transhumanism in some way. We do ask that you limit the piece to 10 pages so it doesn’t break the site. We will accept works that are explicit, but keep the eroticism to a minimum. Once again, make it tasteful.

Articles: We are still looking for authors that focus on articles and op-ed pieces. We are looking for people that have knowledge on these subjects:

In 2017, the European Southern Observatory (ESO) obtained the first ever real photo of a black hole. Six years later, artificial intelligence was able to improve the image.

Here’s What We Know

American scientists have decided to improve the photo of a black hole. The original image shows something resembling a “fuzzy donut”. Experts have applied the PRIMO algorithm, based on machine learning, to improve the image.

“Every day, Apple is innovating to make technology that enriches people’s lives, while protecting the planet we all share.”

In another major move to become greener, Apple announced plans to incorporate more recycled materials into its products, targeting 2025 to attain 100 percent recycled cobalt in all Apple-designed batteries in a press release.

Further plans involving a shift to magnets made of recycled rare earth elements and printed circuit boards using 100 percent recycled tin soldering and gold plating were disclosed, giving all Earth lovers a reason to cheer.

The brain’s processing of reading is fascinating.

Reading is a fascinating process that engages many regions of our brain. We all know it’s an essential skill, but did you know that reading is like weightlifting for our minds? The more we read, the stronger our neural connections become, and the better we get at it. But what happens in our brains when we read? Scientists have been trying to answer this question for years, and a new study has finally shed some light on the matter.

A groundbreaking study led by neuroscientist Oscar Woolnough from the University of Texas Health Science Center at Houston shed new light on how our brains process language. According to the research, two distinct brain networks get activated while reading.
