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

open access: yesAdvanced 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 ...

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

open access: yesAdvanced 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 ...

Impacts of Choerospondias axillaris growth on acidity of Udic Ferrosols in subtropical China

open access: yes, 2005
Changes in acidity of Udic Ferrosols, caused by growth of Choerospondias axillaris (Roxb.) Burtt et Hill, in comparison to wild grass, were investigated for pH distribution in the soil profile, exchangeable acidity, and cation status in the soil leachate

Model-based approach for measurement of basic soil nutrient [PDF]

open access: yesE3S Web of Conferences
The article presents a model-based approach for measuring basic soil nutrients. The model-based approach consists of two main phases: data collection using sensor systems and data pre-processing and analysis.

Culinary Chemistry as a Platform for Interfacial Materials Design

open access: yesAdvanced Materials Interfaces, EarlyView.
Culinary processes control interfaces through heating, shear, gelation, and molecular transport. This Review connects selected gastronomic examples with food‐derived nanomaterials, plasmonic sensing, anthocyanin photovoltaics, and intelligent packaging. Original agar‐based plasmonic films illustrate the proposed translation.

Smart‐Release Ion‐Exchanged Ca‐Montmorillonite for Corrosion Protection of AA2024 Aluminium Alloy

open access: yesAdvanced Materials Interfaces, EarlyView.
Smart‐release anticorrosion pigments based on Zn‐ and Mn‐modified montmorillonite were developed by ion exchange of Ca‐montmorillonite and evaluated for the protection of AA2024 aluminium alloy in artificial acid rain. Both modified pigments provided effective corrosion inhibition, with Zn‐modified montmorillonite (Zn‐MMT) achieving an inhibition ...

Soil acidity changes in bulk soil and maize rhizosphere in response to nitrogen fertilization [PDF]

open access: yes, 2008
The capacity of nitrogen (N) fertilizers to acidify the soil is regulated principally by the rate and N source. Nitrogen fertilizers undergo hydrolysis and nitrification in soil, resulting in the release of free hydrogen (H+) ions.

PHOSPHATE EQUILIBRIA IN ACID SOILS

open access: yesJournal of Soil Science, 1962
Summary Phosphate equilibria in fifty‐four acid soils are examined and referred to equilibria with variscite and strengite. The equilibrium phosphate concentration in British soils is governed by phosphate residues less basic than these compounds and is approximately similar to that obtained by treatments of ...
