“…Nevertheless, stopping the reaction process can affect the main reaction products that are generated after the hydration of Portland cement, such as ettringite, phases, portlandite, or the C-S-H gel. [27,28] In situ analysis of the reactions at earlier ages is usually restricted to large facilities as synchrotron. [3] Additionally, the microstructural information is elusive, and the kinetic implications are difficult to be evaluating in direct experimental setups.…”

The study of the hydration reactions of Portland cement is well documented by conventional techniques such as X‐ray diffraction, differential thermal and thermogravimetric analysis, or NMR, for instance. However, a complete view of all the phases present in the reactions is elusive. In this study, by using an in situ analysis through confocal Raman microscopy (CRM), the reaction of the initial phases (C2S, C3S, and C3A) to form new crystalline phases (portlandite, ettringite, and monosulfate) and amorphous C‐S‐H gel is reported. For the first time, this characterization technique allows to know the distribution and evolution of hydration water. In situ characterization of cement‐based materials opens a new gate to understand the different mechanisms involved in the processes of hydration of a Portland cement, due to the combined chemical and high spatial resolution of CRM.

Five new naphthalenones, two enantiomers (−)-1 and (+)-1 leptothalenone A, (−)-4,8-dihydroxy-7-(2-hydroxy-ethyl)-6-methoxy-3,4-dihydro-2H-naphthalen-1-one ((−)-2), (4S, 10R, 4’S)-leptotha-lenone B (5), (4R, 10S, 4’S)-leptothalenone B (6), and a new isocoumarine, 6-hydroxy-5,8-dimethoxy-3-methyl-1H-isochromen-1-one (4), along with two known compounds (+)-4,8-dihydroxy-7-(2-hydroxy-ethyl)-6-methoxy-3,4-dihydro-2H-naphthalen-1-one ((+)-2) and (+)-10-norparvulenone (3) were isolated from the marine-derived fungus Leptosphaerulina chartarum 3608. The structures of new compounds were elucidated by HR-ESIMS, NMR, and ECD analysis. All compounds were evaluated for cytotoxicity and anti-inflammatory activity. Compound 6 showed moderate anti-inflammatory activity by inhibiting the production of nitric oxide (NO) in lipopolysaccharide-stimulated RAW264.7 cells, with an IC50 value of 44.5 μM.

“…In recent years, biomass waste-derived hydrochars have received considerable interest as effective and environmentally friendly adsorbents for the advanced treatment of different heavy metals. 8,9 Swine manure-derived hydrochars were applied to remove antimony(III) and cadmium(II) ions from aqueous solution. They showed high maximum adsorption capacities (19.80-27.18 mg g À1 for Cd(II) ions, and 2.24-3.98 mg g À1 for Sb(III) ions) through electrostatic adsorption and surface complexation.…”

Influence of interfering anions on Cu²⁺ and Zn²⁺ ions removal on chestnut outer shell-derived hydrochars in aqueous solution

Hydrothermal carbonization method was used to produce different hydrochars from chestnut outer shell at various temperatures while resolving the environmental issues of agricultural bio-waste. Hydrochars were adopted as adsorbents to remove heavy metal ions (copper and zinc ions) from aqueous solution. Hydrochar samples were characterized by Scanning Electron Microscope (SEM), Fourier Transform Infrared (FTIR), and Brunauer-Emmett-Teller (BET) nitrogen adsorption-desorption isotherm. An increase in the hydrothermal temperature from 160 °C to 220 °C results in higher BET surface area (18.81 m2 g-1) and the porosity of the samples. The resultant hydrochar at 220 °C exhibited a more excellent adsorption performance (8.13 mg g-1 for copper nitrate) than the other two hydrochars at low hydrothermal temperature. The current study addressed the influence of interfering anions of nitrates, sulfates and chlorides on the adsorption performance. The result shows that the hydrochar possesses larger removal efficiency for heavy metal nitrates that that of chlorides and sulfates
