Tesla Energy posts record 9.4 GWh of battery storage deployed in Q2 2024

Tesla Energy is no longer a sleeping giant. During the second quarter of 2024, Tesla Energy was able to deploy 9.4 GWh of energy storage products. This represents the highest quarter deployment of energy storage products in Tesla’s history to date.

Tesla Energy was already a standout in the company’s Q1 2024 Update Letter. In the document, Tesla highlighted that Q1’s energy deployments were a new record at 4.1 GWh. As could be seen in Tesla’s Q2 2024 production and delivery report, Q1’s already impressive 4.1 GWh of energy storage deployments grew an astounding 132% quarter-over-quarter and 157% year-over-year.

$TSLA BREAKING: Tesla distributed 9.4 GWh of energy storage in the second quarter of 2024.

Researchers discover photo-induced charge-transfer complex between amine and imide

A research team led by Prof. Zhang Guoqing from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has discovered a highly reactive photo-induced charge-transfer complex (PCTC) between amine and imide. Their findings are published in the journal Chem.

Charge transfer between molecules, a critical process in both natural and synthetic systems, plays a fundamental role in photosynthesis, respiration, and various organic synthesis and energy conversion applications.

Despite extensive research, creating stable, light-responsive charge-transfer complexes in artificial systems remains challenging. The discovery of PCTCs addresses this challenge, offering new insights into complex photochemical processes.

Dual-laser approach could lower cost of high-resolution 3D printing

Researchers have developed a new two-photon polymerization technique that uses two lasers to 3D print complex high-resolution structures. The advance could make this 3D printing process less expensive, helping it find wider use in a variety of applications.

Two-photon polymerization is an advanced additive manufacturing technique that traditionally uses femtosecond lasers to polymerize materials in a precise, 3D manner. Although this process works well for making high-resolution microstructures, it isn’t widely used in manufacturing because femtosecond lasers are expensive and increase the cost of printing parts.

“We combined a relatively low-cost laser emitting with a emitting infrared pulses to reduce the power requirement of the femtosecond laser,” said research team leader Xianfan Xu from Purdue University. “In this way, with a given femtosecond laser power, the printing throughput can be increased, leading to a lower cost for printing individual parts.”

Compactification, Vacuum Energy and Quintessence

We study the possibility that the vacuum energydensity of scalar and internal-space gauge fieldsarising from the process of dimensional reduction ofhigher dimensional gravity theories plays the role of quintessence. We show that, for themultidimensional Einstein-Yang-Mills system compactifiedon a R × S3 × Sdtopology, there are classically stable solutions suchthat the observed accelerated expansion of the Universe atpresent can be accounted for without upsetting structureformation scenarios or violating observational bounds onthe vacuum energy density.

New ink-based method offers best recipe yet for thermoelectric devices

Power plants, factories, car engines—everything that consumes energy produces heat, much of which is wasted. Thermoelectric devices could capture this wasted heat and convert it into electricity, but their production has been prohibitively costly and complex.

Yanliang Zhang, the Advanced Materials and Manufacturing Collegiate Professor of Aerospace and Mechanical Engineering at the University of Notre Dame, and colleagues from a multi-institutional team have devised an ink-based manufacturing method making feasible the large-scale and cost-effective manufacturing of highly efficient thermoelectric devices.

Their finding were recently published in Energy & Environmental Science.

CERN’s ATLAS experiment releases 65 TB of open data for research

The ATLAS Experiment at CERN has made two years’ worth of scientific data available to the public for research purposes. The data include recordings of proton–proton collisions from the Large Hadron Collider (LHC) at a collision energy of 13 TeV.

This is the first time that ATLAS has released data on this scale, and it marks a in terms of public access and utilization of LHC data.

“Open access is a core value of CERN and the ATLAS Collaboration,” says Andreas Hoecker, ATLAS Spokesperson. “Since its beginning, ATLAS has strived to make its results fully accessible and reusable through archives such as arXiv and HepData. ATLAS has routinely released open data for educational purposes. Now, we’re taking it one step further—inviting everyone to explore the data that led to our discoveries.”

MIT Physicists Forge a Five-Lane Quantum Superhighway for Electrons

MIT physicists have developed a new form of graphene, creating a five-lane electron superhighway that allows for ultra-efficient electron movement without energy loss.

This breakthrough in rhombohedral pentalayer graphene could transform low-power electronic devices and operates via the quantum anomalous Hall effect at zero magnetic field.

MIT physicists and their collaborators have created a five-lane superhighway for electrons that could allow ultra-efficient electronics and more.
