Optimisation of Tray Drier Microalgae Dewatering Techniques Using Response Surface Methodology

open access: yesEnergies, 2018
The feasibility of the application of a tray drier in dewatering microalgae was investigated. Response surface methodology (RSM) based on Central Composite Design (CCD) was used to evaluate and optimise the effect of air temperature and air velocity as ...

Development of Holocene lacustrine microbialites on the Iberian Peninsula: Insights into environmental and depositional controls using X‐ray CT and petrography

open access: yesSedimentology, EarlyView.
ABSTRACT Microbial mats and microbialites are common in modern and ancient saline lacustrine environments and are highly responsive to biological and environmental factors. As such, they represent important sources of high‐resolution environmental data across a wide range of geological time. Nonetheless, interpretation of fossil mats is non‐trivial due

Moderate‐Temperature Hydrothermal Treatment Removes Detectable DNA and Antibiotic Resistance Genes From Municipal Sludge While Preserving Resource Value

open access: yesWater and Environment Journal, EarlyView.
This graphical abstract shows the overall study design where dewatered wastewater sludge samples were collected and subjected to a range of HT temperatures. Measurement of nucleic acid concentration and antibiotic resistance gene profiles across temperatures showed that HT at moderate temperatures offers sustainable, scalable sludge sanitation and ARG ...

AGRICULTURAL AND RECREATIONAL IMPACTS FROM SURFACE FLOW CHANGES DUE TO GOLD MINING OPERATIONS [PDF]

open access: yes
Nevada ranks third in the world in gold production. In order to operate the massive open pit gold mines, the State of Nevada granted mining companies a temporary permit to pump groundwater from near the open pits and dispose of it. Certain instream flows

Advancement in Anaerobic Digestion for Scaling‐Up Biogas Production Through Food Waste Valorization

open access: yesChemBioEng Reviews, Volume 13, Issue 2, April 2026.
The review article begins with an introduction that covers the overview, food waste (FW) classification, and the steps involved in producing biogas through anaerobic digestion (AD). Following that, it describes the process for producing biogas, including single‐, two‐, and multistage systems, mesophilic and thermophilic digestion, and wet and dry ...

Investigation of microalgal tolerance and growth in simulated tailings pond water containing naphthenic acids

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1877-1888, April 2026.
Abstract Oil sands tailings ponds, such as those in northeastern Alberta, present environmental challenges due to slow sedimentation, water entrapment, and toxic naphthenic acids (NAs), which hinder water reclamation. This study assessed the tolerance and biodegradation potential of Chlorella vulgaris (C.

Northeastern Greenland Paleomagnetic Records Indicate the Influence of Geomagnetic Flux Lobe Intensity on Virtual Geomagnetic Pole Migration During the Holocene

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Paleomagnetic and rock magnetic analyses were conducted on sediment cores from the northeastern Greenland Shelf and Young Sound along the western edge of Fram Strait. The paleomagnetic signal in all three sediment cores is characterized by a strong and stable single component magnetization carried by low coercivity ferrimagnetic single domain ...
