Researchers have developed a highly effective dual-layer coating that provides 99.6% protection against iron corrosion. The breakthrough combines a thin molecular primer with a durable polymer layer, creating a strong, long-lasting barrier against rust. This innovation could significantly reduce maintenance costs and extend the lifespan of iron-based materials used in construction, transportation, and manufacturing.

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.
