Comparative study of the linear and nonlinear optical properties for different Iraqi heavy and light crude oils

Iraqi Journal of Physics, 2020
Iraqi oil crudes have some of the physical and chemical characteristics that distinguish it from other types of oil crudes in the world. Some of these features such us molecular composition, rheological, viscosity and emulsions are studied carefully by ...

Intensity correlation scan (IC-scan) technique to characterize the optical nonlinearities of scattering media

Scientific Reports, 2023
Light scattering, whether caused by desired or spurious elements, is considered one of the main phenomena that present great challenges for the nonlinear (NL) optical characterization of turbid media.

Third- and fifth-order optical nonlinearities of norbixin

Results in Optics, 2022
In this work, we investigated the nonlinear response of norbixin (C24H28O4) in acetone. The third- and fifth-order optical nonlinearities were measured using the conventional Z-scan technique, with 357 fs laser pulses at 1040 nm and low-repetition rate ...

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

Molecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Large nonlinear absorption in single aggregate of silver nanoparticles observed with z-scan imaging technique

AIP Advances, 2021
Although nonlinear optical spectroscopy of nanostructures, nanomaterials, and nanomedicines has been widely used to observe and study the nature of nonlinear optical (NLO) phenomena, the field has to improve for the single nanostructure system.

EZ-scan: Single beam measurement technique for thin-film nonlinearities

, 1994
The EZ-scan, an improved Z-scan technique, shows a sensitivity for measuring nonlinearly induced wavefront distortion of ≈Λ/104. We show that the nonlinear refraction and nonlinear absorption coeficients can be determined separately by a single EZ-scan ...
