Iron-Doped Cadmium Sulfide/Graphene Oxide (CdFeS/GO) Nanocomposites for Photocatalytic Degradation of Toxic Pollutants.

Heterogeneous photocatalysis has been widely explored as a promising solution for dye degradation due to its cost-effectiveness, ease of recovery, and use of green technology. Precisely, iron-doped cadmium sulfide (CdS) exhibits greater efficiency because of its higher charge separation, more electron transfer efficiency, and adsorption under visible region. In this study, two different ratios of iron-doped cadmium sulfide (CdFeS/GO) nanocomposites such as CdFeS/GO and CdFeS/GO were synthesized using the coprecipitation method and characterized with UV-Vis DRS, XRD, FT-IR, Raman, XPS, and HR-TEM.

Integrating machine learning algorithm with sewer process model to realize swift prediction and real-time control of HS pollution in sewer systems.

The frequent occurrence of safety incidents in sewer systems due to the emergency toxicity of hydrogen sulfide (HS) necessitate timely and efficient prediction, early warning and real-time control. However, various factors influencing HS generation and emission leads to a substantial computational burden for the existing dynamic sewer process models and fails to timely control the HS exposure risk. The present study proposed a swift prediction model (SPM) that combined the validated dynamic sewer process model (the biofilm-initiated sewer process model, BISM) with a high-speed machine learning algorithm (MLA), achieving accurately and swiftly predict the dissolved sulfide (DS) concentration and HS concentration in a specific sewer network.

Visible Light Triggerable CO Releasing Micelles.

Carbon monoxide (CO), along with nitric oxide and hydrogen sulfide, is one of a trinity of known gasotransmitters, or endogenously produced gaseous molecules that signal and regulate a panoply of physiological functions.

Surveying the available triggers, photolysis is potentially advantageous: It is contactless and grants practitioners unparalleled spatial and temporal control.

Various technologies have been employed to remove the HS gas from these industries, and choosing appropriate HS removal technologies is a complex multi-criteria decision-making (MCDM) problem.

Erucin, a Natural Isothiocyanate, Prevents Polyglutamine-Induced Toxicity in via /AMPK and /FOXO Signaling.

Several neurodegenerative diseases (NDDs), such as Huntington's disease, six of the spinocerebellar ataxias, dentatorubral-pallidoluysian atrophy, and spinobulbar muscular atrophy, are caused by abnormally long polyglutamine (polyQ) tracts. Natural compounds capable of alleviating polyQ-induced toxicity are currently of great interest. In this work, we investigated the modulatory effect against polyQ neurotoxic aggregates exerted by erucin (ERN), an isothiocyanate naturally present in its precursor glucoerucin in rocket salad leaves and in its oxidized form, sulforaphane (SFN), in broccoli.

Enhanced sulfide burial in low-oxygen aquatic environments could offset the carbon footprint of aquaculture production.

Carbon removal from the atmosphere is needed to keep global mean temperature increases below 2 °C. Here, we develop a model to explore how alkalinity production through enhanced iron sulfide formation in low-oxygen aquatic environments, such as aquaculture systems, could offer a cost-effective means of CO removal. We show that enhanced sulfide burial through the supply of reactive iron to surface sediments may be able to capture up to a hundred million tonnes of CO per year, particularly in countries with the highest number of fish farms, such as China and Indonesia.
