A research team at the Korea Institute of Science and Technology (KIST) has developed a thermally refractory material that maintains its optical properties even at temperatures of 1,000 degrees Celsius and in strong ultraviolet illumination. The material can be used in various applications ranging from space and aerospace to thermal photovoltaic (TPV) systems.

Thermal radiation is the term used to define the electromagnetic radiation emitted from all matter whose temperature is above absolute zero. The radiation results from the heat generated when charges in the material move and are released in the form of electromagnetic radiation.

Scientists have been working on tapping this radiation as a form of energy source. The heat from facilities such as thermal power generation plants and industrial sites can be repurposed for heating, cooling, and even energy production when suitable thermal refractory materials are available.

With the support of electrical transport and magnetic measurement systems of Steady High Magnetic Field Facility (SHMFF), a research team from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), discovered a new superconducting material called (InSe2)xNbSe2, which possesses a unique lattice structure. The superconducting transition temperature of this material reaches 11.6 K, making it the transition metal sulfide superconductor with the highest transition temperature under ambient pressure.

The results were published in Journal of the American Chemical Society.

TMD materials have received lots of attention due to their numerous applications in the fields of catalysis, energy storage, and integrated circuits. However, the relatively low superconducting transition temperatures of TMD superconductors have limited their potential use.

Large energetic laser facilities provide an amazing tool for bringing matter into high energy density states but achieving a good energy conversion requires to optically smooth the high-power laser beams. Optical smoothing reduces the laser spatial and temporal coherences, allowing to mitigate the development of unwanted laser–plasma instabilities (LPI). Two schemes have been mainly developed: polarization smoothing and smoothing by spectral dispersion. Here, we focus on the latter. Smoothing by spectral dispersion consists in broadening the spectrum usually through a sinusoidal phase modulation and dispersing it with an optical grating. It is usually considered that the modulation frequency should be equal to the inverse of the time delay of the grating, because it maximizes the number of uncorrelated speckles patterns at a given bandwidth. However, current optical smoothing designs are still not sufficient for mitigating LPI. Because the optical smoothing system possesses degrees of freedom, we propose to improve the optical smoothing efficiency by a better tuning of those parameters. Considering the Laser Mégajoule optical system framework, we show that an increase in the modulation frequency allows a better efficiency of the smoothing while keeping the same bandwidth. We assess the efficiency by looking at a better mitigation of the stimulated Brillouin scattering that, due to its dangerousness in hohlraums developed for inertial confinement fusion applications in the indirect drive scheme, serves as a witness instability.

Energy utility Origin Energy says it will spend $400 million on a new big 650 MWh big battery to be built at the site of its main gas generator in Victoria.

The board approval for the Mortlake Power Station battery, to be sized at 300 MW and 650 MWh, follows approval for the first stage of the Eraring big battery in NSW – at the site of its soon-tobe-shuttered coal fired power station – and a growing list of other battery projects.

Origin has chosen US-based energy storage systems supplier Fluence to build the project. Site preparation is expected to begin in a couple of months and the battery will be operating in late 2026.

Engineers and material scientists have been trying to develop increasingly advanced devices, to meet the growing needs of the electronics industry. These devices include electrostatic capacitors, devices that can store electrical energy in a dielectric between a pair of electrodes through the accumulation of electric charge on the dielectric surfaces.

These capacitors are crucial components of various technologies, including electric vehicles and photovoltaics (PVs). They are often fabricated using polymers as dielectric materials, synthetic substances made up of large organic molecules with good intrinsic flexibility and insulating properties.

Researchers at Tsinghua University and other institutes in China recently introduced a new strategy to fabricate polymer composites filled with subnanosheets exhibiting highly advantageous properties. Their proposed method, outlined in a Nature Energy paper, allowed them to fabricate a 100-meter-long roll of a polymer-based subnanocomposite film.

High-power, high-energy ultrafast fiber lasers are indispensable tools in various fields, from basic and applied science research to industrial processing. However, due to thermal effects, nonlinear effects, there is always a limit to the power/energy expansion of a single fiber laser amplifier.

Coherent beam combination (CBC) technology is an effective strategy to break through the limits of a single fiber laser amplifier and further achieve power/energy scaling.

Under the conditions of mutual coherence and stable phase relationship, multiple laser beams can be superimposed and mutually interfere with each other. This approach allows for an improvement in average power and pulse energy by a factor almost equal to the total number of combined channels. However, with the increase of beam combining channels, the complexity of CBC systems also increases, bringing negative impacts such as decreased beam combining efficiency, degraded beam quality, and increased operational difficulty to the system.

The IVO quantum inertia drive is in orbit now and will be turned on within one to ten weeks and then operated for many weeks or months.

The IVO quantum inertia drive is very controversial because it would go against many theories in physics.
