Exploring Influence of MgO/Na2O on Melting Characteristics and Viscosity–Temperature Characteristics of Coal Slags Under Entrained Flow Gasification Condition

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Characteristics of high alkali in Zhundong coal ash may cause ash‐related slag discharge problems at entrained‐flow‐bed (EFB) gasifier. In this study, through exploring melting characteristics and viscosity–temperature characteristics, it is found that MN05, MN14, and MN23 show low FTs (< 1160°C).

Advancing Environmental Sustainability: The Role of Artificial Intelligence in Monitoring, Predicting, and Controlling Sulfur Dioxide Emissions

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Air pollution from sulfur dioxide (SO2) emissions poses significant threats to environmental sustainability, public health, and climate change efforts. Despite advances in monitoring and regulatory frameworks, traditional methods often fall short in accuracy, scalability, and efficiency.

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

open access: yesThe Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Expanding Metabolic Online Monitoring Capabilities in 96‐Deepwell Microtiter Plates by Combining Optoelectronic O2 and CO2 Sensors

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT To increase the information content in early stages of bioprocess development, various technologies have been introduced for monitoring cultivations in microtiter plates (MTPs). Besides spectroscopical measurements, like in the BioLector technology, optical measurements with luminescent sensors, placed directly in the cultivation medium ...

Interaction of calcium lignosulfonate with tricalcium silicate, hydrated tricalcium silicate, and calcium hydroxide

open access: yesCement and Concrete Research, 1972
Abstract Tricalcium silicate, bottle-hydrated tricalcium silicate and calcium hydroxide were each treated with 0.015–1.0% calcium lignosulfonate (CLS) using water or dimethyl sulfoxide. At low CLS concentrations C 3 S hydrates and irreversibly adsorbs CLS. At concentrations beyond about 0.25–0.35% the hydration of C 3 S is inhibited.
