A green approach for enhancing the electrocatalytic activity and stability of NiFe2O4/CB nanospheres towards hydrogen production
(2020)Among the exfoliation processes applied on layered materials, it is the first time to explore the ultrasonic exfoliation in water for improving the catalytic properties of NiFe2O4/CB (CB = carbon black) nanospheres towards ... -
Green CSR practices: A European approach
(2014)In their business strategy, companies incorporate their concerns on global environmental problems by setting their principles on sustainability with CSR. An in depth analysis will provide a general view of how European ... -
A green extraction process for polyphenols from elderberry (Sambucus nigra) flowers using deep eutectic solvent and ultrasound-assisted pretreatment
(2020)Sambucus nigra flowers, known as elderberry flowers (EBF), are a plant tissue rich in polyphenolic phytochemicals with important bioactivities. However, there are few studies dealing with the production of polyphenol-containing ... -
Green Manuring for Low-input Irrigated Maize Cultivation as an Energy Crop in Mediterranean Climates
(2021)Introduction of high input crops to existing rotation schemes for bio-energy production such as corn in Mediterranean areas would only be possible by improving its yield and decreasing the cultivation costs. This work ... -
Green remediation of toxic metals contaminated mining soil using bacterial consortium and Brassica juncea

Green Valorization of Olive Leaves to Produce Polyphenol-Enriched Extracts Using an Environmentally Benign Deep Eutectic Solvent
(2020)Olive leaves (OLL) are considered to be a highly appreciated bioresource of bioactive polyphenolic phytochemicals, embracing several different structures. However, extraction processes based on deep eutectic solvents (DES) ... -
Green video delivery in LTE-based heterogeneous cellular networks
(2015)In this paper we present an optimization framework that formalizes the inherent trade-off between the user perceived quality of wireless video, and the energy consumption cost of the network. The former is formulated in ... -
Greenhouse biofumigation with Melia azedarach controls Meloidogyne spp. and enhances soil biological activity
(2018)The need for environmentally friendly agricultural practices has led to the development of plant-based nematicides for root-knot nematode control. The efficacy of these botanicals has been tested primarily under laboratory ... -
Greenhouse cooling by a fog system: Effects on microclimate and on production and quality of a soilless pepper crop
(2006)The influence of greenhouse humidity control on greenhouse microclimate, crop transpiration rate, and yield and fruit quality of a soilless grown pepper crop was studied in a greenhouse located in the coastal area of western ... -
Greenhouse evaporative cooling: Measurement and data analysis
(2000)Temperature and humidity gradients were investigated during summer in a rose production greenhouse equipped with a ventilated cooling-pad system and a half shaded plastic roof. In a steady regime, the cooling process reached ... -
Greenhouse evaporative cooling: Measurement and data analysis
(2001)Temperature and humidity gradients were investigated during summer in a commercial greenhouse producing cut roses, equipped with a ventilated cooling-pad system and a half-shaded plastic roof In a steady regime, the cooling ... -
Greenhouse integrated photovoltaics (GIPV): Effects in microclimatic parameters and canopy production
(2020)Energy demand of greenhouses is an important factor for their economics, and photovoltaics (PV) can be used as an alternative method to supply electrical energy for electrical and heating needs. Infrared (IR) radiation ... -
