Chitosan‐Based pH‐Responsive Films and Edible Coatings to Enhance Fruit Shelf‐Life: Impact of Plant Biomolecules and Composition

open access: yesFood Chemistry International, EarlyView.
Chitosan based coatings/films forming solution with the use ofplant extracts and parameters for fruit shelf life analysis. ABSTRACT Fresh fruits are a natural source of various minerals and vitamins, which are essential for human health. However, a rapid rate of respiration, water loss and fast ripening ability result in shorter shelf life and ...

Mineral Acquisition from Clay by Budongo Forest Chimpanzees [PDF]

open access: yes, 2015
Chimpanzees of the Sonso community, Budongo Forest, Uganda were observed eating clay and drinking clay-water from waterholes. We show that clay, clay-rich water, and clay obtained with leaf sponges, provide a range of minerals in different concentrations.

Enhancing Soil Aggregation and Water Retention by Applying Kaolinite Clay to Post‐Tin‐Mined Land on Belitung Island, Indonesia

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Post‐mining sandy soils have low water retention, which causes soil particle separation and persistent soil erosion. Although organic matter is commonly used for soil restoration, it is lightweight, washes away during heavy rain, and decomposes under strong sunlight.

Sedimentary lithofacies, petrography and diagenesis of the Kapuni group in the Kapuni Field, Taranaki Basin, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science with Honours in Earth Science at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2004
The reservoir architecture and quality of the Kapuni Group sandstones in seven wells (Kapuni−1, −3, −8, −12, Deep−1, 14 and −15) in the Kapuni Field are characterised using available core and digital geophysical log data.

Adsorption Characteristics of Bixin on Acid- and Alkali-Treated Kaolinite in Aprotic Solvents

open access: yesBioinorganic Chemistry and Applications, 2018
The adsorption of bixin in aprotic solvents onto acid- and alkali-treated kaolinite was investigated. Kaolinite was treated three times, for 6 h each, with 8 M HCl or 5 M KOH. The adsorbents were characterized by XRD, FT-IR, EDS, and BET-N2.

Nutrition Status of Trees on Spoil Heaps After Coal Mining Can Be Inferred From Seasonal Dynamics of Foliar Nutrient Concentrations

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT A stable vegetation cover on given habitat conditions can be one of the possible requirements for post‐mining sites, as it can prevent erosion and dustiness of these anthropogenic surfaces and bring several practical future benefits, such as biomass production and microclimate improvement.
