Battery Breakthrough Could Allow Electric Cars To Go 1,000 km on Single Charge

Posted by in categories: nanotechnology, particle physics, robotics/AI, sustainability, transportation

Futuristic advancements in AI and healthcare stole the limelight at the tech extravaganza Consumer Electronics Show (CES) 2024. However, battery technology is the game-changer at the heart of these innovations, enabling greater power efficiency. Importantly, electric vehicles are where this technology is being applied most intensely. Today’s EVs can travel around 700km on a single charge, while researchers are aiming for a 1,000km battery range. Researchers are fervently exploring the use of silicon, known for its high storage capacity, as the anode material in lithium-ion batteries for EVs. However, despite its potential, bringing silicon into practical use remains a puzzle that researchers are still working hard to piece together.

Enter Professor Soojin Park, PhD candidate Minjun Je, and Dr. Hye Bin Son from the Department of Chemistry at Pohang University of Science and Technology (POSTECH). They have cracked the code, developing a pocket-friendly and rock-solid next-generation high-energy-density Li-ion battery system using micro silicon particles and gel polymer electrolytes. This work was published on the online pages of Advanced Science on the 17th of January.

Employing silicon as a battery material presents challenges: It expands by more than three times during charging and then contracts back to its original size while discharging, significantly impacting battery efficiency. Utilizing nano-sized silicon (10-9m) partially addresses the issue, but the sophisticated production process is complex and astronomically expensive, making it a challenging budget proposition. By contrast, micro-sized silicon (10-6m) is superbly practical in terms of cost and energy density. Yet, the expansion issue of the larger silicon particles becomes more pronounced during battery operation, posing limitations for its use as an anode material.

Valentine’s Day 2024: Scientists create gel to mend broken hearts — How does it work?

Posted by in categories: biotech/medical, chemistry, engineering, nanotechnology

Scientists have created a wood pulp hydrogel to strengthen anti-cancer medications and restore damaged cardiac tissue.

Now that they have created a novel hydrogel that can be utilised to repair damaged heart tissue and enhance cancer therapies, you can cure a broken heart on Valentine’s Day, according to SciTech Daily.

Dr Elisabeth Prince, a researcher in chemical engineering at the University of Waterloo, collaborated with scientists from Duke University and the University of Toronto to design a synthetic material that is made of wood pulp-derived cellulose nanocrystals. The material’s unique biomechanical qualities are recreated by engineering it to mimic the fibrous nanostructures and characteristics of human tissues.

Researchers solve a foundational problem in transmitting quantum information

Posted by in categories: computing, nanotechnology, quantum physics

Future quantum electronics will differ substantially from conventional electronics. Whereas memory in the latter is stored as binary digits, the former is stored as qubits, which can take many forms, such as entrapped electrons in nanostructures known as quantum dots. However, challenges in transmitting this information to anything further than the adjacent quantum dot have limited qubit design.

Now, in a study recently published in Physical Review Letters, researchers from the Institute of Industrial Science at the University of Tokyo are solving this problem, They developed a new technology for transmitting quantum information over perhaps tens to a hundred micrometers. This advance could improve the functionality of upcoming .

How can researchers transmit quantum information, from one quantum dot to another, on the same quantum computer chip? One way might be to convert electron (matter) information into light (electromagnetic wave) information—by generating light–matter hybrid states.

Gold nanoparticles found to reverse brain deficits in multiple sclerosis and Parkinson’s

Posted by in categories: biotech/medical, nanotechnology, neuroscience

Results from phase two clinical trials at UT Southwestern Medical Center showed that a suspension of gold nanocrystals taken daily by patients with multiple sclerosis (MS) and Parkinson’s disease (PD) significantly reversed deficits of metabolites linked to energy activity in the brain and resulted in functional improvements.

The findings, published in the Journal of Nanobiotechnology (“Evidence of brain target engagement in Parkinson’s disease and multiple sclerosis by the investigational nanomedicine, CNM-Au8, in the REPAIR phase 2 clinical trials”), could eventually help bring this treatment to patients with these and other neurodegenerative diseases, according to the authors.

Gold nanocrystals suspended in a water buffer represent a novel therapeutic agent developed by Clene Nanomedicine for neurodegenerative conditions. This nanomedicine, called CNM-Au8, is being investigated to treat patients with multiple sclerosis and Parkinson’s disease in clinical trials at UT Southwestern.

The Next Wave of Nanomaterials: Precision-Engineered Nanoscrolls

Posted by in categories: nanotechnology, particle physics

Janus nanosheets bring unprecedented control to preparation of nanoscrolls.

Researchers from Tokyo Metropolitan University have come up with a new way of rolling atomically thin sheets of atoms into “nanoscrolls.” Their unique approach uses transition metal dichalcogenide sheets with a different composition on either side, realizing a tight roll that gives scrolls down to five nanometers in diameter at the center and micrometers in length. Control over the nanostructure in these scrolls promises new developments in catalysis and photovoltaic devices.

Advancements in Nanotechnology.

Beyond cells: Unveiling the potential of genetic circuits on single DNA molecules

Posted by in categories: bioengineering, biotech/medical, genetics, nanotechnology

In a new Nature Communications study, researchers have explored the construction of genetic circuits on single DNA molecules, demonstrating localized protein synthesis as a guiding principle for dissipative nanodevices, offering insights into artificial cell design and nanobiotechnology applications.

The term “genetic circuit” is a metaphorical description of the complex network of genetic elements (such as genes, promoters, and ) within a cell that interact to control and cellular functions.

In the realm of artificial cell design, scientists aim to replicate and engineer these genetic circuits to create functional, self-contained units. These circuits act as the molecular machinery responsible for orchestrating cellular processes by precisely regulating the production of proteins and other molecules.
