The Utilisation of Solid Fuels Derived from Waste Pistachio Shells in Direct Carbon Solid Oxide Fuel Cells.
The comprehensive results regarding the physicochemical properties of carbonaceous materials that are obtained from pistachio shells support their usage as solid fuels to supply direct carbon solid oxide fuel cells (DC-SOFCs). The influence of preparation conditions on variations in the chemical composition, morphology of the biochar powders, and degree of graphitization of carbonaceous materials were […]
Utilization of the UAE date palm leaf biochar in carbon dioxide capture and sequestration processes
This paper evaluates the potential use of date palm leaf biochar as a climate change solution through CO2 capture and sequestration. The pyrolysis of date palm leaf was performed at different temperatures 300°, 400°, 500°, and 600 °C. The physicochemical characteristics of the synthesized biochar were examined using Scanning Electron Microscopy (SEM) with Energy Dispersive X-Ray […]
Improved fertiliser management to reduce the greenhouse-gas emissions and ensure yields in a wheat-peanut relay intercropping system in China.
Over the last century, anthropogenic greenhouse-gas (GHG) emissions have changed the global climate, and agriculture plays an important role in the global flux of GHG. Agricultural management practices, such as split N applications and the use of controlled-release fertilisers have significantly increased the crop yield and N-use efficiency by balancing the N demand of crops […]
Green production of hydrochar nut group from waste materials in subcritical water medium and investigation of their adsorption performance for Crystal Violet.
This study evaluates the production of hydrochars from the outer shells of the nut group (peanut, hazelnut, walnut, and pistachio) in an eco-friendly SWM medium and their effects as adsorbents on the removal of crystal violet (CV) from an aqueous solution. The prepared hydrochars were characterized using Brunauer Emmett-Teller (BET) analysis, scanning electron microscope (SEM), […]
Selective limb removal pruning and reflective ground covers improve light and crop distributions in the lower zone of ‘Nonpareil’almond trees but not total yield.
Conventional planting and management systems for almond (Prunus dulcis (Mill.) D. A. Webb) orchards involve trees trained from an early age to produce multiple large scaffold branches, which in mature orchards form closed light inefficient canopies. Treatments included a single round of selective limb removal pruning applied at the start of the research to remove […]
Date Fruit Processing Waste and Approaches to Its Valorization: A Review.
In the Middle East and North Africa, dates are a traditional and economically valuable crop, playing an essential role in people's daily diets. Date fruit production and related processing industry generate a large quantity of waste; for illustration, the date juicing industry produces roughly 17-28% Date press cake (DPC), which is mainly discarded in open […]
Experimental and Theoretical Studies on Extract of Date Palm Seed as a Green Anti-Corrosion Agent in Hydrochloric Acid Solution.
Extracts from plant materials have great potential as alternatives to inorganic corrosion inhibitors, which typically have harmful consequences. Experimental and theoretical methodologies studied the effectiveness of agricultural waste, namely, date palm seed extract as a green anti-corrosive agent in 0.5 M hydrochloric acid. Experimental results showed that immersion time and temperature are closely related to […]
Pyrolysis of Almond (Prunus amygdalus) Shells: Kinetic Analysis, Modelling, Energy Assessment and Technical Feasibility Studies.
The aim of this work was to study the thermogravimetric analysis through the pyrolysis of almond (Prunus amygdalus) shells for evaluating its potential for bioenergy at different heating rates (10, 25, and 50 K min-1). The activation energy values for the process were of the range of 153.0, 152.02, and 152.73 kJ mol-1 as calculated by […]
Healthier and more sustainable diets: What changes are needed in high‐income countries?.
Debate persists around the food production and dietary changes needed to improve sustainability of our global food system. We reviewed 29 studies in high-income countries that used various methodologies to define a healthier, more sustainable diet. Diets aligned with dietary guidelines, containing less meat and higher amounts of plant-derived foods (vegetables, pulses [beans/lentils], fruit, wholegrains, […]
Sugarcane/peanut intercropping system improves physicochemical properties by changing N and P cycling and organic matter turnover in root zone soil
Background: The sugarcane/peanut intercropping system is a specific and efficient cropping pattern in South China. Intercropping systems change the bacterial diversity of soils and decrease disease rates. It can not only utilized light, heat, water and land resources efficiently, but also increased yield and economic benefits of farmers. Methods: We determined soil nutrients, enzymes […]
