This review systematically examines how self-assembled molecules enhance the performance and stability of perovskite optoelectronic devices, focusing on their properties, mechanisms, and rational design strategies.

 

Sensors are used everywhere—from smartphones and wearable devices to industrial systems and logistics. But traditional sensors often rely on rigid components and batteries, limiting their applications in soft systems. To address this, researchers from Shibaura Institute of Technology, Japan, have come up with a smarter alternative. Using the paper-folding technique in combination with a triboelectric nanogenerator, they developed a novel energy-harvesting sensor with promising potential for next-generation soft devices.

Until now, it seemed to be an immutable law that a clock twice as accurate requires at least twice as much energy. But now a team of researchers from TU Wien, Chalmers University of Technology, Sweden, and University of Malta have demonstrated that special tricks can be used to increase accuracy exponentially.

In this paper, Al, Al-Mg, Al-Si core-shell coated samples and physical mixture samples with PVDF were prepared using two different methods. The prepared samples and combustion products were characterized in terms of morphology through SEM-FIB and XRD techniques. Additionally, the combustion and energy release characteristics of the samples were evaluated through combustion performance tests, closed-volume pressure tests, and thermal analysis experiments.

This research offers valuable insights into optimizing the structure of platinum-based catalysts to enhance their catalytic activity and stability. The ultra-low platinum loading ORR electrocatalyst developed in this study has the potential to significantly reduce the cost of fuel cells and zinc-air batteries, making them more viable for commercial applications. The findings pave the way for the development of more efficient and cost-effective energy conversion devices.

Using the Summing Nal Detector (SuN), a team of experimental and theoretical scientists took another step in understanding how an atomic nucleus can have two different shapes corresponding to only slightly different energy levels.

New research published by Michigan State University astrophysicists could help scientists answer a century-old question: where did galactic cosmic rays come from?
