Biologically inspired graphene-chlorophyll phototransistors with high gain [PDF]
arXiv, 2013 We present prominent photoresponse of bio-inspired graphene-based phototransistors sensitized with chlorophyll molecules. The hybrid graphene-chlorophyll phototransistors exhibit a high gain of 10^6 electrons per photon and a high responsivity of 10^6 A/W, which can be attributed to the integration of high-mobility graphene and the photosensitive ...

Upstream Causes of Downstream Effects [PDF]
, 2017 The United States Environmental Protection Agency considers nutrient pollution in stream ecosystems one of the U.S. most pressing environmental challenges. But limited independent replicates, lack of experimental randomization, and space- and time-varying confounding handicap causal inference on effects of nutrient pollution. In this paper the causal g-

Food Science &Nutrition, Volume 11, Issue 1, Page 320-333, January 2023., 2023 Nowadays, consumers have an increasing preference for vegetables produced using healthier and environmentally friendly techniques. The postharvest quality of fresh‐cut celery is affected by nitrogen (N) fertilizer rate and type (organic and chemical) as well as postharvest treatments.

Food Science &Nutrition, Volume 11, Issue 1, Page 379-389, January 2023., 2023 A pH‐sensitive indicator based on fish gelatin and Coleus scutellarioides anthocyanin extract (CSAE) was prepared and characterized. There was also a significant relationship between the TVB‐N content of fish fillets and the a* index of the film during the 16 hours storage period so that with the increase of TVB‐N values of the fillets during the ...

Application of Different Simulated Spectral Data and Machine Learning to Estimate the Chlorophyll a Concentration of Several Inland Waters [PDF]
arXiv, 2019 Water quality is of great importance for humans and for the environment and has to be monitored continuously. It is determinable through proxies such as the chlorophyll a concentration, which can be monitored by remote sensing techniques. This study focuses on the trade-off between the spatial and the spectral resolution of six simulated satellite ...

Development and Application of Organic Sonosensitizers in Cancer Therapy
Aggregate, EarlyView.This review provides a comprehensive overview of organic sonosensitizers employed in cancer treatment, describing their underlying mechanisms and structure‐activity relationship in terms of sonodynamic therapy. The significance of nanotechnology and combination therapy with other oncological modalities (photothermal therapy, photodynamic therapy, etc.)

Active Whisker‐Inspired Food Material Surface Property Measurement Using Deep‐Learned Mechanosensor
Advanced Intelligent Systems, EarlyView.Herein, a new application is proposed for an active whisker sensor that mimics the movement of rat whiskers. The whiskers, which are deformed by contact with an object, provide information about surface properties. It is shown that active whisker sensors can be useful in the food industry, and data identification is performed using deep learning ...

Seed treatments with essential oils protect radish seedlings against drought
AIMS Agriculture and Food, 2017 Establishment of seedlings of economic crops is often reduced if there is not a steady supply of water. Essential oils (EO) from plants are increasingly used instead of synthetic chemicals to protect plant and animal products against biotic and abiotic ...

Robustness and Optimality of Light Harvesting in Cyanobacterial Photosystem I [PDF]
arXiv, 2002 As most biological species, photosynthetic lifeforms have evolved to function optimally, despite thermal disorder and with fault tolerance. It remains a challenge to understand how this is achieved. To address this challenge the function of the protein-pigment complex photosystem I (PSI) of the cyanobacterium Synechococcus elongatus is investigated ...
