Cataract surgery with femtosecond lasers

open access: yesSaudi Journal of Ophthalmology, 2011
Cataract surgery with femtosecond lasers is approaching its practical application in ophthalmology. These lasers, working in the near infrared wavelength (1030 nm) can penetrate the transparent and even opaque tissues of the anterior segment of the eye, with limitations related to vessels and mineral opacities.

Dipole‐Manipulated Built‐In Electric Field Enables Ultrafast Charge Separation in Perylene Diimide Polymers for Photoelectrochemical Water Splitting

open access: yesAdvanced Science, EarlyView.
Molecular dipole engineering in dendritic perylene diimide polymers through nitrogen‐rich heterocyclic linkers amplifies the built‐in electric field, enabling sub‐picosecond charge separation and efficient multi‐electron accumulation. This structure–dynamics–performance relationship establishes a versatile design strategy for high‐performance organic ...

Femtosecond-Laser-Produced Underwater “Superpolymphobic” Nanorippled Surfaces: Repelling Liquid Polymers in Water for Applications of Controlling Polymer Shape and Adhesion

open access: yes, 2019
A femtosecond (fs)-laser-processed surface that repels liquid polymer in water is reported in this paper. We define this phenomenon as the “superpolymphobicity”.

Ultrafast Dynamics of Spin Current and Electron Temperature in Spintronic Terahertz Emitters

open access: yesAdvanced Science, EarlyView.
This work quantifies optical‐pump‐induced THz transmission variations to reveal electron and lattice temperature dynamics and presents time‐resolved THz spectral maps for sub‐picosecond analysis. A 63 ± 8 fs time lag between THz emission and laser excitation is identified, serving as an intrinsic parameter limiting the upper frequency of spintronic THz

Rare‐Earth Mediated Engineering in ZnSe@ZnS:Eu3+ to Simultaneously Achieve Structural Modulation and Atomic Eu Doping Sites for X‐Ray Imaging

open access: yesAdvanced Science, EarlyView.
A dual hard‐base anchoring strategy was developed to synthesize ZnSe@ZnS:Eu3+ quantum dots, leveraging fluoride‐oleylamine interactions to create surface atomic Eu doping sites. By precisely tuning temperature, Eu3+ concentration, and fluoride levels, we obtain morphologies ranging from tip growth to coupled flower‐like structures.
