Selective wear of cuttings elements of working organs of tillage machines with realization of self-sharpening effect [PDF]

open access: yes, 2013
The clause of strengthening of cuttings elements is conditioning and realization of such selforganization process as a self-sharpening. Sharpening of horizontal and vertical cuttings elements of working organs of tillage machines (CE WOTM) is considered ...

Molecular Engineering for Enhanced Second‐Order Nonlinear Response in Spontaneously‐Oriented Evaporated Organic Films

open access: yesAdvanced Optical Materials, EarlyView.
Intramolecular bridge‐locking frustrates detrimental anti‐parallel packing in evaporated organic films. This design enhances net polar orientation, leading to a twofold off‐resonance increase in the second‐order nonlinear susceptibility (χ(2)) without electric‐field poling.

Enhancing Triplet Excitons Lifetime Through Controlled Intermolecular Interactions

open access: yesAdvanced Optical Materials, EarlyView.
Singlet fission (SF) is investigated in pentacene embedded in a surface‐anchored metal–organic framework, enabling a molecular arrangement inaccessible in pure organic crystals. This architecture changes the singlet fission dynamics significantly and enhances the triplet lifetime by almost four orders of magnitude.

Incorporating Si into Sb2Se3: Tailoring Optical Phase Change Materials via Nanocomposites

open access: yesAdvanced Optical Materials, EarlyView.
We study the structural, optical, and thermal effects of adding silicon to Sb2Se3 and demonstrate that the as‐deposited solid solution phase segregates after electro‐thermal switching, creating a nanocomposite with effective‐medium properties and a phase‐change response.

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 ...
