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 ...

Infrared-Reflective Coating on Fused Silica for a Solar High-Temperature Receiver [PDF]

, 2007
In concentrating solar power, high-temperature solar receivers can provide heat to highly efficient cycles for electricity or chemical production. Excessive heating of the fused-silica window and the resulting recrystallization are major problems of high-

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 ...

Midnight sector observations of auroral omega bands [PDF]

, 2011
We present observations of auroral omega bands on 28 September 2009. Although generally associated with the substorm recovery phase and typically observed in the morning sector, the features presented here occurred just after expansion phase onset and ...

NbN Broadband Plasmonic Absorbers for Efficient Hot-Carrier Injection Toward Improved Solar-to-Hydrogen Conversion. [PDF]

Adv Sci (Weinh)
Niobium nitride (NbN) broadband plasmonic metasurface absorbers provide an efficient platform for solar‐energy conversion through hot‐carrier injection. Quasi‐epitaxial NbN features a low work function of 4.0 eV, reducing the interfacial injection barrier and facilitating charge transfer into adjacent photocatalysts.

Determining Composition–Structure–Property Relationships in Quaternary Perovskitoids Through Megalibraries

Advanced Materials, EarlyView.
A method to synthesize 1 million compositionally distinct Cs3Bi2‐𝛼Sb𝛼Br9−xIx across a quaternary compositional space on a single glass substrate is presented. High‐throughput characterization is then used to map the interplay of composition, structure, and bandgap.

Defect‐Driven Charge Separation in Ba‐Doped SrTiO3: Correlating Photoelectrochemical Performance With Dye‐Selective Photocatalysis

Advanced Materials Interfaces, EarlyView.
Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.

Light‐Controlled Localized Delamination and Blistering of Azobenzene‐Containing Polymer Thin Films in an Aqueous Environment

Advanced Materials Interfaces, EarlyView.
When exposed to light of a defined wavelength, the photoisomerization of azobenzene chromophores leads to polymer reorientation, generating stresses that result in solvent‐facilitated localized delamination of the film from the substrate. Additionally, blisters that form spontaneously when exposed to an aqueous environment can be manipulated via ...

Ultra‐White Elastomeric Coatings for Daytime Radiative Cooling

Advanced Materials Technologies, EarlyView.
Passive daytime radiative cooling meets elasticity in a new class of ultra‐white silicone coatings. Combining high solar reflectance with strong sky‐window emission, they hold surfaces below ambient temperature under full sunlight while remaining flexible and stretchable. This combination of cooling performance and mechanical flexibility enables energy‐
