Multi‐Dielectric Metasurfaces for Ultrabright, Tunable Structural Color and Reconfigurable Optical Filtering with Extraordinarily Large Color Span

open access: yesAdvanced Optical Materials, EarlyView.
Structural color generation is an emerging field for digital display and printing applications. This report presents a novel truncated‐cone design and the first use of GaP sandwiched between two layers of TiO2, demonstrating ultra‐bright, tunable colors with a record color gamut.

Naphthyridine‐Based Donor–Acceptor Boron Difluoride Complexes Targeting Red Emission in Organic Light‐Emitting Diodes

open access: yesAdvanced Optical Materials, EarlyView.
Four donor–acceptor boron difluoride complexes based on triphenylamine donor and a naphthyridine acceptor units were synthesized, studied, and applied as OLED emitters. They exhibit pronounced intramolecular charge transfer character, balanced charge transport properties, and tunable emission. Near‐unity PLQYs are achieved for selected compounds, while

Solution Properties and Chain Dimensions of Poly(n-alkyl methacrylates)

open access: yes, 1984
The influence of n-alkyl side-chain length on the unperturbed chain dimensions of poly(n-alkyl methacrylates) has been examined. For the cases where the side-chain groups were decyl (C10), tridecyl (C13), stearyl (C18), and docosyl (C22), the unperturbed

Harnessing Ultrafast Optical Pulses for 3D Microfabrication by Selective Tweezing and Immobilization of Colloidal Particles in an Integrated System

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Microfabrication using nano‐ to micron‐sized blocks has transformative potential for next‐gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. STIC, a single‐laser system for precise colloid manipulation and immobilization using femtosecond lasers, is introduced that enables efficient 3D ...

Mechanistic Investigation of Poly Acrylates and Poly Methacrylates Pyrolysis

open access: yes, 1996
The pyrolysis of free radically prepared low molecular weight poly(n-butyl acrylate) (n-BA), (n-butyl methacrylate) (n-BMA), (t-butyl methacrylate) (t-BMA), and their copolymers with various concentrations of acrylonitrile (AN) were investigated by ...
