Herein, walnut shell (WS) was utilized as the raw material for production of purified cellulose. The technique involves multiple treatments, including alkaline treatment and bleaching. Furthermore, two nanocellulose materials were derived from WS by 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO) oxidation sulfuric acid hydrolysis, demonstrating broad applicability value walnuts. micromorphologies, crystalline structures, chemical functional groups, thermal stabilities obtained via...

An extension of the Gerchberg–Saxton algorithm from two dimensions to three is used configure a continuous optical trap geometry. Intensity tailoring in continuous, three-dimensional (3D) volume rather than multiple discrete two-dimensional planes yields flexible 3D holographic tweezers. A numerical simulation and demonstrations beam shaping particle trapping confirm capabilities method.

Polybutylene adipate-terephthalate (PBAT) offers a convincing ecological alternative to the traditional fossil-based plastics due its biodegradability and robust mechanical properties. The objective of this study is develop PBAT-based bio-composite films through incorporating functionalized cellulose nanocrystals (CNC) curcumin (CUR). In order improve interfacial compatibility with PBAT matrix co-doping CUR, CNC was modified using dodecyl succinic anhydride (DxCNC). ternary system, CUR...

We propose and demonstrate multiple shearing interferometry for measuring two-dimensional phase object. Multi-shear interference can effectively eliminate the problem of spectral leakage that results from single-shear interference. The Fourier coefficients a wavefront are computed differences obtained interferograms, which acquired by interferometer, desired is then reconstructed. Numerical optical tests have confirmed has higher recovery accuracy than reconstruction precision increases as...

We demonstrate a tunable broadband near-infrared absorber composed of VO2 /Al2O3/ITO layers with facile lithography-free method. Simulated and experimental spectra show that absorption bands above 90% absorptance can be tuned from 1.62 ∼ 2.42 μm to 1.2 1.5 by thermally induced phase transition. Furthermore, the in intermediate state yield perfect over wavelength range 2.5 μm. Besides high performance still remained at incident up 70° for both polarizations due presence ultrathin layer (λ/52)...

We report on the active Q-switching laser performance of Yb:GdCa4O(BO3)3 crystal, demonstrated by employing an acousto-optic Q-switch in a compact plano-concave resonator. Stable repetitively Q-switched operation is achieved with pulse repetition rates varying from 30 to 0.2 kHz, producing average output power 10.2 W at 1027.5 nm kHz rate, optical-to-optical efficiency 30%. The maximum energy generated lowest rate 4.75 mJ, width being 11 ns, gives rise peak that amounts 432 kW.
