Photosystem II‐Carbon Nitride Photoanodes for Scalable Biophotoelectrochemistry

open access: yesAdvanced Materials, EarlyView.
A spray‐freeze method is developed to fabricate large‐area (up to 33 cm2) macroporous carbon nitride photoanodes integrated with photosystem II enzymes for biophotoelectrochemical systems. The photoanodes reach a Faradaic efficiency of 93.5% for O2 evolution.

Chlorophyll a Sensitiser [PDF]

open access: yesNature, 1900
IT was with a feeling of great satisfaction that I read the concluding lines of Dr. H. Brown's highly interesting presidential address (NATURE, September 14, 1899). I was glad to see that this distinguished chemist, to whom the physiology of plants is so much indebted, adopts certain views on the chlorophyll function, which I have been defending for ...

On a method of determination of chlorophyll in cells of algae collected on a membrane filter. [Translation from: Trudy Instituta Biologii Vnutrennykh Vodnany 11(14), 198-202, 1966.] [PDF]

open access: yes, 1966
The original method, proposed by Yentsch (1957), of determination of chlorophyll directly in the cells, attracts attention by its simplicity. In order to measure the content of chlorophyll by this method, a determined volume of suspension of algae is ...

The First Review on Nano‐Agricultural Applications of MXene and MBene‐Based Materials for Plant‐Immunoengineering, Controlled Protection, and Inducing Biostimulation Mechanisms

open access: yesAdvanced Materials, EarlyView.
MXene and MBene nanomaterials show significant potential in addressing critical challenges in biomedicine, applied biology, agriculture, and the environment. From a nano‐agricultural perspective, this relatively young field has witnessed emerging advances towards applications for plant‐immunoengineering, biostimulation, and controlled delivery ...

Assessment of the viability of using saline reclaimed water in grapefruit in medium to long term

open access: yesSpanish Journal of Agricultural Research, 2014
Citrus trees are strongly affected by salinity, especially in countries where irrigation is required as a semi-arid Mediterranean agronomic region. The aims of the study were i) to identify the best reliable plant-based water status indicator for field ...

Sediment‐Resistant Marine Antifouling Coating Based on Amphiphilic Copolymer Brushes Bearing Sulfobetaine and Isobornyl Pendants

open access: yesAdvanced Materials Interfaces, EarlyView.
Amphiphilic copolymer coatings comprising sulfobetaine methacrylate (SBMA) and isobornyl methacrylate (IBMA) are reported, synthesized via SI‐ATRP, that resist biological fouling and sediment accumulation. The copolymer coating with an SBMA:IBMA feed molar ratio of 1:1 is optimal for reducing diatom adhesion and sediment adsorption.

Applications of QSPR and Machine Learning in Molecular Photonics

open access: yesAdvanced Optical Materials, EarlyView.
Quantitative structureproperty relationships (QSPR) and machine learning (ML) are transforming photochemistry by enabling pre‐synthetic screening of photoactive molecules. This review outlines advances in data‐driven discovery of optical materials and functional dyes, identifies effective descriptors and models for photophysical processes, and provides

The Use of Chlorophyll Meters to Assess Crop N Status and Derivation of Sufficiency Values for Sweet Pepper [PDF]

open access: yes, 2019
Chlorophyll meters are promising tools for improving the nitrogen (N) management of vegetable crops. To facilitate on-farm use of these meters, sufficiency values that identify deficient and sufficient crop N status are required.
