Zinc and Nickel Accumulation in Unicellular Photosynthetic Algae Chlamydomonas reinhardtii Grown in Metal-contaminated Media

Zkeri E., Mavrakis E., Pergantis S., (Corresponding) Lydakis-Simantiris N.
Topic: 
Heavy metals in the environment
In this study, Zn and Ni accumulation in unicellular freshwater migroalga Chlamydomonas reinhardtii was investigated. C. reinhardtii cells were grown in media polluted with several concentrations of either Zn or Ni. Tolerance of this organism to Zn and Ni pollution was examined and the growth...Read more

Modelling the Evaporation Flux from Shallow Sandy Aquifers

(Corresponding) Al-Suwaiyan M.
Topic: 
Soil and groundwater contamination and remediation
A mathematical model based on Richard’s equation and the soil hydraulic properties was developed in order to understand the influence of the soil depth to the water table on the maximum potential evaporative flux through the unsaturated zone. The model was applied on shallow aquifers using...Read more

Low temperature conversion of methanol to higher hydrocarbons and hydrogen using a non-thermal plasma

(Corresponding) Dahiru U., Zhang K., Harvey A.
Topic: 
Environmental odour, monitoring and control
In recent years, the emission of volatile organic compounds (VOCs) from chemical manufacturing plants, agricultural practises, and indoor sources has attracted public concern, as these emissions have a negative effect on both human health and the environment.
