Efficient Selective Adsorption of Anionic Dyes by Modified Activated Alumina Spheres

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The persistent environmental threat from dye‐contaminated industrial wastewater necessitates advanced remediation solutions. Hydrochloric acid–modified activated alumina spheres (HAAs) are presented as efficient adsorbents for anionic dye removal.

Rhodamine B Adsorption Efficiency of Biochar Produced Through Co‐Pyrolysis of Municipal Sewage Sludge and Food Waste Mixture Under High‐Temperature Condition

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT With the large‐scale construction of wastewater treatment facilities, the production of municipal sewage sludge continues to rise. This sludge contains substantial amounts of toxic and hazardous substances, and improper disposal may lead to secondary environmental pollution.

The upper chromatic number of quasi-interval co-hypergraphs

Le Matematiche, 1997
We investigate the structural and colouring properties of clique hyper-graphs of interval graphs called the quasi-interval hypergraphs. We find the conditions when they are interval hypergraphs. The upper chromatic number for the clique co-hypergraphs of

Unlocking fruit dimensions: Quantification of functional traits driving plant–frugivore interactions

Applications in Plant Sciences, EarlyView.
Abstract Fleshy fruits attract animals to ingest fruit, swallow the seeds, and release them in the landscape, thus facilitating seed dispersal and plant regeneration. Attraction of animal dispersers is achieved via attractants such as color or scent, and rewards like sugars, lipids, and micronutrients.
