17+ min ago (228+ words) Scientists have created a new, scalable material, gallium sulfide grown by atomic layer deposition, that rivals the optical performance of pristine crystals and promises to improve the efficiency of integrated photonic circuits and augmented reality displays. https://quantumzeitgeist.com/wp-content/uploads/Image_fx-19-15.jpg Large-Area GaS Films Grown by Atomic Layer Deposition Scientists have developed a robust method for fabricating large-scale, high-quality gallium sulfide (GaS) films using atomic layer deposition, overcoming limitations in traditional van der Waals material implementation. The team grew thick GaS films on large-area substrates, achieving thicknesses of approximately 20 micrometers while maintaining exceptional structural and optical properties. Energy-dispersive X-ray spectroscopy confirmed near-ideal stoichiometry with a Ga:S atomic ratio of 49. 5:50. 5, and scanning electron microscopy revealed a continuous, macroscopic foil-like film capable of withstanding substrate release without fracturing. Optical profilometry measurements confirmed the substantial thickness and uniformity of the deposited layers. Raman spectroscopy, employing both…...

5+ hour, 11+ min ago (760+ words) [Could life on Earth have begun in surface-bound gels that predated the first cells? Credit: ChemSystemChem/Khanum, et al. (2025)]Surface-bound gels may have provided the structure and chemistry necessary for life to take root on Earth. These findings could also have implications in the search for life beyond Earth. The most widely held theory, known as abiogenesis, holds that life arose naturally from non-living matter, but questions remain about the evolutionary pathways involved. In a recent paper, an international team of researchers from Japan, Malaysia, the UK, and Germany suggests that the answer may involve surface-bound prebiotic gels that existed long before the first cellular organisms emerged. Their research provides new insights into the origins of life on Earth and how scientists could search for it elsewhere in the Universe. The team's "prebiotic gel-first" theory posits that surface gels with…...

5+ hour, 25+ min ago (226+ words) Scientists have developed a new laser-based technique to transform ultraviolet-absorbing crystals into efficient visible-light photocatalysts, achieving rapid degradation of pollutants through the creation of a unique hybrid material with enhanced charge separation. https://quantumzeitgeist.com/wp-content/uploads/Capture-534.jpg Wide-bandgap van der Waals crystals currently limit efficiency in solar energy conversion due to their limited absorption of visible light. This research presents a new strategy for creating cadmium phosphorus trisulfide (CdPS3) with tailored properties using femtosecond pulsed laser ablation in liquid, a technique that precisely controls material creation. By carefully controlling the laser process, scientists engineered the phase and optoelectronic properties of CdPS3, addressing a key challenge in developing more efficient solar energy materials. CdPS3 Nanoparticles Synthesized by Laser Ablation As a quantum scientist exploring the frontiers of physics and technology. My work focuses on uncovering how quantum mechanics, computing, and emerging technologies are transforming our understanding of reality....

8+ hour, 9+ min ago (1712+ words) The Asgard archaea bear traits that hint at how eukaryotes first emerged Microbes first found around hydrothermal vents offer clues to how all complex life may have emerged on Earth " and maybe beyond. In many submerged regions, murky mud shelters strange life-forms that seem to be the key to one of the biggest mysteries of life on Earth. In 2015, game-changing research made the case that these odd microbes can explain the origin of eukaryotes, the domain of life that includes organisms made of cells containing a membrane-bound nucleus. Since then, an explosion of studies has added to evidence that the Asgard archaea are the key to the birth of all known complex life. The rise of the eukaryotes was one of the most important events in Earth's history. If it had not occurred, there would be no great white sharks,…...
