Rice research could make weird AI images a thing of the past

Rice University researchers developed ElasticDiffusion, a method that separates local and global signals to create non-square aspect ratio images without visual imperfections. The new approach can improve consistency and realism in AI-generated images, but still requires significant computational power.

New method in the fight against forever chemicals

Researchers at ETH Zurich have developed a new method to degrade perfluorooctane sulfonates (PFOS), a subgroup of forever chemicals. Using piezocatalysis, the team was able to break down 90.5% of PFOS molecules in water samples, offering a potential solution to environmental pollution.

Charging ahead towards future low-cost polymer zinc-ion batteries

Researchers have developed a lab-made pouch battery using scaled-up polymer at an approximate cost of $20 / kg, achieving a capacity of nearly 70 mAh g’  and a middle discharge voltage of 1.4 V. This breakthrough paves the way for producing low-cost alternatives to lithium-ion batteries.
