Multiwavelength Brillouin-Thulium Fiber Laser
IEEE Photonics Journal, 2014 We demonstrate the first multiwavelength Brillouin-thulium fiber laser (BTFL) with wavelengths near 1.97 μm. The multiwavelength fiber laser was realized based on stimulated Brillouin scattering and nonlinear polarization rotation effects.

Light bullet generation via stimulated Brillouin scattering
APL PhotonicsWe propose an all-optical approach to generating space–time wave packets in a multimode slab waveguide via the multilevel interband stimulated Brillouin scattering process. Two pump sources and a single-mode signal are fed into the waveguide.

Flattening Energy Puddles for Enhanced Charge Transport in Wrinkled WSe2
Small, EarlyView.Strain‐inducing wrinkles in 1L‐WSe2 create carrier‐trapping energy puddles. Trioctylphosphine selenide (TOPSe) selectively passivates Se vacancies at these wrinkle sites, while steric hindrance suppresses basal‐plane reaction. Comprehensive suite of space‐resolved spectroscopic techniques reveals reduced nonradiative recombination, longer exciton ...

High-Efficiency Optical Parametric Oscillator Based on Stimulated Brillouin Scattering Pulse Shaping
IEEE Photonics Journal, 2019 We present an optical parametric oscillator (OPO) that uses a pump pulse shape tailored by stimulated Brillouin scattering. The theoretical analysis is carried out for comparison between Gaussian pump and the step function pulse pump.

AGP and EXO‐LIKE genes promote brassinosteroid‐dependent anisotropic growth
New Phytologist, EarlyView.Summary The brassinosteroid pathway promotes anisotropic cell expansion; however, the effectors in this process remain unclear. Candidates include ARABINOGALACTAN PROTEIN (AGP) genes, which are prominent brassinosteroid‐responsive transcriptional targets, and EXORDIUM (EXO)‐LIKE (EXL) genes.

Aggregation of Modified Glucuronoxylan in Water and DMSO
Biopolymers, Volume 117, Issue 3, May 2026.Neutron scattering study of dispersibility of glucuronoxylan and modified glucuronoxylan, in water and dimethyl sulfoxide (DMSO). ABSTRACT Glucuronoxylans are known to be only partly soluble in aqueous media. Chemical modification often aims to improve solubility, yet observations of aggregation even of the modified xylans are not uncommon.
