Developing Novel DNA-Based Mechano-Technologies For Human Health — Dr. Khalid Salaita, Ph.D. — Emory University

Dr. Khalid Salaita, Ph.D. (https://www.salaitalab.com/salaita) is a Professor of Chemistry at Emory University in Atlanta, Georgia (USA), program faculty in the Department of Biomedical Engineering at Georgia Tech and Emory, program member of Cancer Cell Biology at Winship Cancer Institute, and most recently is the recent winner Future Insight Prize given by Merck KGaA, Darmstadt, Germany (https://www.emdgroup.com/en/research/open-innovation/futurei…aming.html) for his cutting edge work in the area of mechanobiology.

Dr. Salaita earned his B.S. in Chemistry, from Old Dominion University, his Ph.D. in Chemistry from Northwestern University, completed a postdoctoral fellowship in the Department of Chemistry at the University of California, Berkeley, and then started his own lab at Emory University, investigating the interface between living systems and engineered nanoscale materials. To achieve this goal, his group has pioneered the development of tools like molecular force sensors, DNA mechano-technology, smart therapeutics, and nanoscale mechanical actuators to help manipulate living cells.

Scientists have created an innovative model membrane electrode with hollow giant carbon nanotubes and a wide range of nanopore dimensions. The invention aids in understanding electrochemical behaviors and could significantly advance our knowledge of porous carbon materials in electrochemical systems.

Researchers at Tohoku University and Tsinghua University have introduced a next-generation model membrane electrode that promises to revolutionize fundamental electrochemical research. This innovative electrode, fabricated through a meticulous process, showcases an ordered array of hollow giant carbon nanotubes (gCNTs) within a nanoporous membrane, unlocking new possibilities for energy storage and electrochemical studies.

The key breakthrough lies in the construction of this novel electrode. The researchers developed a uniform carbon coating technique on anodic aluminum oxide (AAO) formed on an aluminum substrate, with the barrier layer eliminated. The resulting conformally carbon-coated layer exhibits vertically aligned gCNTs with nanopores ranging from 10 to 200 nm in diameter and 2 μm to 90 μm in length, covering small electrolyte molecules to bio-related large matters such as enzymes and exosomes. Unlike traditional composite electrodes, this self-standing model electrode eliminates inter-particle contact, ensuring minimal contact resistance — something essential for interpreting the corresponding electrochemical behaviors.

Immortality has been a dream of human beings since the dawn of time. Mankind´s fascination with cheating death is reflected in scientific records, mythology, and folklore dating back at least to ancient Egypt.

Now, Ray Kurzweil, a former Google engineer, claims that humans will achieve immortality by 2030 – and 86 percent of his 147 predictions have been correct.

Kurzweil spoke with the YouTube channel Adagio, discussing the expansion in genetics, nanotechnology, and robotics, which he believes will lead to age-reversing “nanobots.”

An older research article and I really hope I didn’t already post this, but isn’t this scary? Nevermind AI or nano, but the fact you don’t need that to mess with your mind? Oh and I’ve searched google and there’s nanoparticles in meds, including psych meds. EMF could potentially mess with that or the minerals in your body but I’m not an expert. But we do have iron in our blood. I read that EMF can affect the blood brain barrier as well. I know there’s issues with people saying they’re targeted individuals, but with instructions online on how to make a microwave gun, especially on youtube, and there’s a Wired Magazine article about a court case where a judge ordered a man to stop EMF targeting a former business partner over an argument over a business deal. Yup, the 21st centure is bringing more than guns and knives and fists into the foray.

From our archives. This important article first published by GR in August 2004 brings to the forefront the role of Psychotronic weapons as an instrument of modern warfare.

Using nanostructured glass, scientists from the University of Southampton’s Optoelectronics Research Centre (ORC) have developed the recording and retrieval processes of five dimensional (5D) digital data by femtosecond laser writing.

The storage allows unprecedented properties including 360 TB/disc data capacity, thermal stability up to 1,000°C and virtually unlimited lifetime at room temperature (13.8 billion years at 190°C) opening a new era of eternal data archiving. [source].

Whether it’s baking a cake, constructing a building, or creating a quantum device, the caliber of the finished product is greatly influenced by the components or fundamental materials used. In their pursuit to enhance the performance of superconducting qubits, which form the bedrock of quantum computers, scientists have been probing different foundational materials aiming to extend the coherent lifetimes of these qubits.

Coherence time serves as a metric to determine the duration a qubit can preserve quantum data, making it a key performance indicator. A recent revelation by researchers showed that the use of tantalum in superconducting qubits enhances their functionality. However, the underlying reasons remained unknown – until now.

Scientists from the Center for Functional Nanomaterials (CFN), the National Synchrotron Light Source II (NSLS-II), the Co-design Center for Quantum Advantage (C2QA), and Princeton University investigated the fundamental reasons that these qubits perform better by decoding the chemical profile of tantalum.

A new “atomic memory” device that encodes data atom by atom can store hundreds of times more data than current hard disks can, a new study finds.

“You would need just the area of a postage stamp to write out all books ever written,” said study senior author Sander Otte, a physicist at the Delft University of Technology’s Kavli Institute of Nanoscience in the Netherlands.

Engineers have been trying to devise increasingly efficient and low-cost methods to fabricate electronic components and devices on a large-scale. Recently, some studies explored the possibilities of creating electronics using solution processing techniques, which involve the deposition of materials with electrical properties from a solution onto a surface.

Researchers at Yonsei University and Sungkyunkwan University in South Korea recently fabricated wafer-scale transistor arrays based on the inorganic compound molybdenum-disulfide using a solution processing method. Their paper, published in Nature Electronics, could contribute to enabling the large-scale and low-cost fabrication of next-generation electronics.

“We have been working on solution-processed 2D nanomaterials for scalable electronic applications for years, yet satisfying both electronic performance and scalability based on solution-based approaches has been very challenging until now,” Joonhoon Kang and Jeong Ho Cho, co-authors of the paper, told Tech Xplore.

Large area metalenses are on the horizon.

In this section, we briefly discuss the presented technique of VSB/CP e-beam writing in comparison with two other contemporary high-resolution lithographic patterning approaches: multibeam e-beam lithography, also known as complementary electron beam lithography (CEBL),16 and optical lithography.

Today’s optical lithography tools are basically well able to address the feature-sizes of the elements presented in the previous section. The exposure in those tools is based on a demagnified imaging of a pattern containing photomask. With this parallel approach, optical lithography is always much faster than any direct-write technique. The central question for making a choice between optical lithography or VSB/CP-based e-beam lithography is, therefore, the effort needed to achieve the required optical performance. For the optical lithography, this is related to the quality of the mask. A high-resolution optical pattern may require a very fine approximation of the mask pattern, leading to large writing times in a mask shop and thus to considerable costs. Consequently, the choice between the different techniques must include considerations on the number of elements required and the price for which the final consumer product can be sold. This cannot be generalized.
