Quantum mechanics gives us power, but no answers

Posted by in categories: energy, quantum physics

The quest to understand quantum mechanics has led to remarkable technological advancements, granting us power and control over the natural world. However, despite these successes, the paradoxes and mysteries surrounding the theory continue to challenge our understanding of reality. This raises the question of whether science, particularly quantum mechanics, provides us with true comprehension of the world or merely equips us with power without deeper understanding, writes John Horgan.

Researchers demonstrate a low-power “wake-up” receiver one-tenth the size of other devices.

MIT

MIT is an acronym for the Massachusetts Institute of Technology. It is a prestigious private research university in Cambridge, Massachusetts that was founded in 1861. It is organized into five Schools: architecture and planning; engineering; humanities, arts, and social sciences; management; and science. MIT’s impact includes many scientific breakthroughs and technological advances. Their stated goal is to make a better world through education, research, and innovation.

Vast Potential — Researchers Create a New Type of Laser

Posted by in categories: energy, materials

Researchers from EPFL and IBM have created a novel laser that could revolutionize optical ranging technology. This laser is constructed from lithium niobate, a material frequently utilized in optical modulators to regulate the frequency or intensity of light transmitted through a device.

Lithium niobate is highly valued for its ability to manage large amounts of optical power and its high “Pockels coefficient.” This allows the material to alter its optical properties when an electric field is applied to it.

The researchers achieved their breakthrough by combining lithium niobate with silicon nitride, which allowed them to produce a new type of hybrid integrated tunable laser. To do this, the team manufactured integrated circuits for light (“photonic integrated circuits”) based on silicon nitride at EPFL, and then bonded them with lithium niobate wafers at IBM.

Two massive gravity batteries are nearing completion in the US and China

Posted by in categories: energy, sustainability

The system helps to plug the gap when it comes to renewable energy sources.

As a solution to the unpredictable nature of renewable energy sources like solar and wind power, gravity batteries are being pitched as an ideal remedy. To further this cause, Swiss startup Energy Vault is now completing two such units, which are situated near Shanghai in China and Texas in the United States.

The basic idea behind a gravity battery system is to lift a heavy object, such as a large mass of concrete or a weight, on a pulley, using energy from a power source. When energy is needed, the thing can fall, and the potential energy is converted back into electricity.

The Kardashev Scale

Posted by in categories: energy, physics, space

The kardeshev scale of possible future technological advance.


In 1964, Russian astrophysicist Nikolai Kardashev figured that civilizations can be categorized by the total amount of energy available to them. He called it the Kardashev Scale. He initially came up with 3 civilization types; type 1, type 2, and type 3. However, other astronomers have recently extended the scale from type 0 all the way to type 7 as new theories in modern physics have emerged. Check out the complete playlist as we unveil each level of the Kardashev Scale! Enjoy the videos, and do let us know your thoughts in the comments!

Researchers fabricate mechanical metamaterials with ultra-high energy absorption capacity

Posted by in categories: energy, physics

Chinese researchers have successfully fabricated mechanical metamaterials with ultra-high energy absorption capacity using ion track technology. The results were published in Nature Communications as an Editor’s Highlight.

The study was conducted by the researchers from the Materials Research Center of the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) and their collaborators from Chongqing University.

Mechanical metamaterials refer to a class of composite materials with artificially designed structures, which exhibit extraordinary mechanical properties that traditional materials do not have. Among them, energy absorption can absorb more efficiently, which requires the material itself to equip both and high strain capacity, which, however, hardly co-exist in general.

Researchers in Japan develop a new ultra-high-density sulfonic acid polymer electrolyte membrane for fuel cells

Posted by in categories: energy, transportation

In a project commissioned by the New Energy and Industrial Technology Development Organization (NEDO), researchers at Nagoya University in Japan have developed poly(styrenesulfonic acid)-based PEMs with a high density of sulfonic acid groups.

One of the key components of environmentally friendly polymer electrolyte fuel cells is a (PEM). It generates through a reaction between hydrogen and oxygen gases. Examples of practical fuel cells include fuel cell vehicles (FCVs) and combined heat and power (CHP) systems.

The best-known PEM is a membrane based on a perfluorosulfonic acid polymer, such as Nafion, which was developed by DuPont in the 1960s. It has a good proton conductivity of 0.1 S/cm at 70–90 °C under humidified conditions. Under these conditions, protons can be released from sulfonic acid groups.
