Operando X-ray spectroscopy is a powerful tool for probing electrocatalyst dynamics—but intense X-ray exposure can distort structural insights. A recent article reveals flux- and dose-dependent ...

AFM-IR technology provides critical data on polymer compositions and properties, supporting the development of advanced ...

Scientists at the National University of Singapore (NUS) have demonstrated a perovskite–organic tandem solar cell with a ...

Researchers at the Solar Energy Research Institute of Singapore (SERIS) have claimed a record 26.4% conversion efficiency in ...

Energy-tunable XPS reveals accurate surface chemistry of Ti3C2Tx MXenes, correcting for adsorbates and improving ...

A powerful pulsed laser beam was directed at one side of the head, with a detector placed on the other side. Only a few ...

Quantum dots are microscopic semiconductor crystals developed in the lab that share many properties with atoms, including the ability to absorb or emit light, a technology that Los Alamos researchers ...

An element can absorb photons of many different energies due to multiple possible transitions between different energy levels. In atomic spectra, absorption and emission lines are very sharp because ...

They found that photon trapping led to a remarkable increase in the absorption efficiency over a wide band in the NIR spectrum, staying above 68 percent and peaking at 86 percent. Notably, the ...

A new non-generated two photon absorption (TPA) spectrum measurement was demonstrated. A white light super continuum beam (WLSC) with spectrum range from 500 nm to 720 nm was used for the measurement.

From the perspective of theory, an important aspect for ETPA is determining what factors in the molecular electronic structure make the ETPA action spectrum different from that for TPA. One issue in ...
