Spatial Manipulation of a Supercontinuum Beam for the Study of Vortex Interference Effects

open access: yesApplied Sciences, 2020
In this work, we generate optical vortices from the supercontinuum output of an ultrafast laser interacting with a micro-structured fiber. Using a segmented spatial light modulator, multiple vortices are designed and dynamically generated and shifted in ...

Adaptive Flattop Beam Shaping With a Spatial Light Modulator Controlled by the Holographic Tandem Method

open access: yesIEEE Photonics Journal, 2016
This paper reports the realization of a closed-loop feedback system, which consists of a spatial light modulator controlled by the holographic tandem method, for adaptive far-field flattop beam shaping.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

3D fluorescence emission difference microscopy based on spatial light modulator [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2016
We report three-dimensional fluorescence emission difference (3D-FED) microscopy using a spatial light modulator (SLM). Zero phase, 0–2π vortex phase and binary 0-pi phase are loaded on the SLM to generate the corresponding solid, doughnut and z-axis ...

Speckle-free laser marking of metals using liquid-crystal-based spatial light modulator [PDF]

open access: yes, 2013
A liquid-crystal-based spatial light modulator (LC-SLM) is used for laser beam patterning and manipulation in order to produce very small, speckle-free 2D marks on metal surfaces.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Correction of Distorted Wavefront Using Dual Liquid Crystal Spatial Light Modulators

open access: yesPhotonics, 2022
In space optical communication, owing to the influence of atmospheric turbulence, optical beams lose focus and become phase-distorted, which reduces the communication quality.

Optimal liquid crystal modulation controlled by surface alignment and anchoring strength

open access: yes, 2012
Spatial modulation of liquid crystals can be controlled and adjusted by light polarization, the degree of pretilt on the substrates, anchoring strength, and the experimental geometry.

Tuning the FBG period with a spatial light modulator

open access: yes, 2022
Paper BM2D.4We present uniform and chirped fiber Bragg gratings inscribed using femtosecond pulses with a deformed wavefront generated by a spatial light modulator.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
