Over 95% Optical Reflectance From Structurally Modulated All‐Biopolymer Multilayers

Advanced Materials, EarlyView.
A new dense–porous design turns ordinary polysaccharides into highly reflective photonic multilayers. Alternating dense pectin and porous cellulose nanofiber layers create strong refractive‐index contrast without inorganic or synthetic polymers, enabling nearly perfect visible reflection, high near‐infrared reflection, broadband metallic‐like colors ...

Preparation and Properties of Microarc Oxidation Self-Lubricating Composite Coatings on Aluminum Alloy

Metals, 2017
Microarc oxidation (MAO) coatings were prepared on 2024-T4 aluminum alloy using pulsed bipolar power supply at different cathode current densities. The MAO ceramic coatings contained many crater-like micropores and a small number of microcracks.

Near‐Infrared Imaging of H2O2 in Plants With Nanosensors Under Environmentally Changing Conditions

Advanced Materials, EarlyView.
This paper reports a ratiometric nanosensor enabling robust, multivariate detection of stress signals (H2O2) in plants, with high resistance to light fluctuations and mechanical disturbances. Single‐walled carbon nanotubes serve as the sensor, Egyptian Blue nanosheets serve as a stable reference, and plant autofluorescence serves as a label‐free ...

Reducing Interfacial Separation Force in High‐Speed Constrained‐Surface Projection Stereolithography Using a Dual‐Modulus Silicone Release Film

Advanced Materials Interfaces, EarlyView.
A dual‐modulus silicone release film creates distributed stress concentrations at high‐/low‐modulus boundaries, triggering multi‐site crack initiation and rapid interfacial detachment. The architecture lowers the peak separation force by 97.6%, shortens detachment time, and enables stable continuous projection stereolithography at 720 mm h−1, offering ...

Development of a Solid‐Liquid Hybrid Electrolyte Composed of LiTa2PO8 and [C2mim][FSA]–Li[FSA] Ionic Liquid for Rechargeable Lithium Metal Batteries

Advanced Materials Interfaces, EarlyView.
LiTa2PO8 (LTPO) suffers from high interfacial resistance when paired with Li metal due to poor solid‐solid contact. Coating LTPO with an ionic liquid (IL) markedly improves interfacial stability, maintaining favorable resistance up to 2000 cycles. However, contact between IL‐coated LTPO and Li metal induces discoloration of LTPO, which is attributed to

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

Advanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...
