The chlorophyll content in water bodies is one of the most important indicator parameters in water quality assessment, red tide warning, carbon cycling, and ecosystem research. Laser-induced fluorescence spectroscopy (LIFS) offers considerable potential fo ...

The significant computational expenses associated with simulating the Laser Powder Bed Fusion (LPBF) process often restrict the insights gained from modeling endeavors to specific combinations of process parameters, hindering broader conclusions. In this s ...

Spin waves (SWs) are collective excitations of spins in magnetically ordered materials. The quantized form of a SW is known as a magnon. SWs excited in ferrimagnetic insulators such as yttrium iron garnet (YIG) can transmit angular momentum over distances ...

Tunable electro-optic metasurfaces have proven to be excellent platforms when it comes to compact and fast modulation of free space light [1] which makes them relevant for applications like coherent laser ranging[2] and fast spatial light modulators. In th ...

This study points out the importance of the templating effect in hybrid organic-inorganic perovskite semiconductors grown on graphene. By combining two achiral materials, we report the formation of a chiral composite heterostructure with electronic band sp ...

Reflectivity modulation is a critical feature for applicationsin telecommunications, 3D imaging and printing, advanced laser machining,or portable displays. Tunable metasurfaces have recently emerged asa promising implementation for miniaturized and high-p ...

The Overhauser Dynamic Nuclear Polarization (O-DNP) of H-1 nuclei usually involves a dipolar coupling with the polarizing agent, whereas scalar coupling via hyperfine interactions are more common with C-13 nuclei. Here, we show a scalar-coupling dominated ...

Raman scattering-based biomedical detection has usually been proposed with near-infrared laser sources. However, a low-cost CMOS imager's quantum efficiency is optimum around green wavelength, and their sensitivity substantially decreases in near-infrared ...

We propose a system of coupled microring resonators for the generation frequency combs and dissipative Kerr solitons in silicon at telecommunication frequencies. By taking advantage of structural slow-light, the effective non-linearity of the material is e ...

Time-resolved Raman spectroscopy techniques offer various ways to study the dynamics of molecular vibrations in liquids or gases and optical phonons in crystals. While these techniques give access to the coherence time of the vibrational modes, they are no ...

Nickel iron oxyhydroxide is the benchmark catalyst for the oxygen evolution reaction (OER) in alkaline medium. Whereas the presence of Fe ions is essential to the high activity, the functions of Fe are currently under debate. Using oxygen isotope labeling ...

We demonstrate, to the best of our knowledge, the first spatiotemporally mode-locked dispersion-managed fiber laser. The fiber oscillator, which includes a 250 modes multimode fiber section, generates 20 nJ pulses centered at 1034 nm with 730 mW average po ...

Optical-pump terahertz-prohe (OPTP) spectroscopy is a powerful, non-contact tool for extracting the electrical conductivity within a material. In this work, we show how OPTP spectroscopy can he used to extract the temperature-dependent electron mobility an ...
