Widely tunable and monochromatic terahertz (THz) difference frequency generation with organic crystal DSTMS was investigated experimentally. A double-pass KTiOPO4 optical parametric oscillator, pumped by a frequency-doubled Nd:YAG laser, employed as the source of dual wavelength. The THz tuning spectrum covered range 0.88−19.27 THz. dependence output on thickness pump wavelength studied. results were well explained based theoretical calculations. With energy 2.47 mJ, reached 85.3 nJ/pulse at...
We report an experimental study on widely tunable terahertz (THz) wave difference frequency generation (DFG) with hydrogen-bonded crystals 2-(3-(4-hydroxystyryl)-5,5-dime-thylcyclohex-2-enylidene) malononitrile (OH1). The organic were pumped by a ∼1.3 μm double-pass KTiOPO4 optical parametric oscillator. A tuning range of 0.02–20 THz was achieved. OH1 offer long effective interaction length (also high output) for the below 3 THz, owing to low absorption and favorable phase-matching. highest...
Abstract “Molecular science” has long been regarded as the golden rule to guide design of organic materials’ performances in past many years, but some interesting phenomena conventional aggregation‐caused fluorescence quenching and new aggregation‐induced emission reflect that properties would be changed from “molecule” “aggregate”. Therefore, “molecular theory faces certain limitations regulating performance materials at aggregation. In this work, it is discovered photosensitizer's contain...
Terahertz spectroscopic characterization and DFT calculations of vanillin cocrystals with nicotinamide isonicotinamide.
Photoactivated adenylate cyclases (PACs) are light activated enzymes that combine blue sensing capacity with the ability to convert ATP cAMP and pyrophosphate (PPi) in a light-dependent manner. In most of known PACs regulation is provided by domain using flavin which undergoes structural reorganization after blue-light absorption. This minor change then translated toward C-terminal protein, inducing larger conformational results conversion cAMP. As key second messenger numerous signal...
Anharmonicity of molecular vibrational motions is closely associated with the thermal property crystals. However, origin anharmonicity still not fully understood. Low-frequency vibrations, which are usually defined in terahertz (THz) range, show excellent sensitivity to anharmonicity. In this work, isonicotinamide form I was investigated by using temperature-dependent time-domain spectroscopy and quasi-harmonic approximation (QHA) approach at PBE-D3 PBE-MBD levels. Both DFT calculations...
Lung cancer is a leading fatal malignancy in humans. p53 mutants exhibit not only loss of tumor suppressor capability but also oncogenic gain-of-function, contributing to lung initiation, progression and therapeutic resistance. Research shows that V157F R158L occur with high frequency squamous cell carcinomas. Revealing their conformational dynamics critical for developing novel therapies. Here, we used all-atom molecular (MD) simulations investigate the effect substitutions on structural...
Polymorphism commonly exists in organic molecular crystals. The fingerprint features low-frequency vibrational range are important information reflecting different intermolecular interactions of polymorphs. Interpreting these is very helpful to understand property polymorphs and reveal the thermodynamic stability. In this work, vibrations form I II vanillin investigated using terahertz time-domain spectroscopy. Static DFT calculation ab initio dynamics (AIMD) employed interpret their both...
High-valent iron–oxo species ( FeⅤ=O) generated through peroxide activation by Fe-based catalysts can realize the selective and efficient degradation of organic pollutants in water treatment. However, effective generation FeⅤ=O is challenging, its oxidation mechanism unclear. Herein, a N, P, S co-doped Fe-single atom (SA) catalyst (FeSA-NPS@C) with FeN4 active center was synthesized as highly for peroxymonosulfate (PMS) FeⅤN4=O being dominant reactive species. For ofloxacin (OFX), rate...
