TL;DR: The hydrodistilled oils from the aerial parts of Bupleurum montanum and B. plantagineum, which are endemic to North Africa, including Algeria, were analyzed by gas chromatography-mass spectrometry and exhibited moderate antimicrobial activity.
Abstract: The hydrodistilled oils from the aerial parts of Bupleurum montanum and B. plantagineum, which are endemic to North Africa, including Algeria, were analyzed by gas chromatography-mass spectrometry (GC-MS). Ninety-eight compounds were detected in the oil of B. montanum, representing 98.6% of the total oil, and 68 in the oil of B. plantagineum, representing 99.8% of the total. Megastigma-4,6-(E),8(2)-triene was the major constituent of B. montana oil (25.3%). Other important compounds were myrcene, alpha-pinene and benzyl tiglate. Conversely, the major constituents of the oil of B. plantagineum were alpha-pinene (31.9%), cis-chrysanthenyl acetate (28.2%), and myrcene (24.8%), followed by the monoterpene hydrocarbon limonene (5.1%). The mutagenic, antiplasmodial and antimicrobial activities of the essential oils were individually evaluated against eleven microorganisms, using the agar diffusion method, by determination of MIC values. The investigated oils exhibited moderate antimicrobial activity. Maximum activity of the oils was observed against Nocardia asteroides, Staphylococcus aureus and Enterococcus faecalis. Fungicidal activity against Candida albicans was also found for both oils.

TL;DR: In this paper, the specific surface area of β-dicalcium silicate decreased with temperature and X-ray diffraction studies were conducted to determine the nonevaporable water, calcium hydroxide (CH) contents, and specific surface areas of the hydrated samples.
Abstract: Calcium silicate hydrate was prepared by hydrothermal reaction between calcium oxide and silica (C/S = 2.0) at a temperature of 205°-215°C and a pressure of 17-19 bar. This reaction with decomposition at 900°C produced highly reactive β-dicalcium silicate (specific surface area 4.55 m 2 /g) contaminated with small amounts of wollastonite as an impurity. Infrared spectral studies have shown that β-dicalcium silicate prepared at 900°C is less symmetric compared with the control prepared at 1450°C using boron trioxide as a stabilizer. The specific surface area of β-dicalcium silicate decreased with temperature. The hydration studies were done by determining the nonevaporable water, calcium hydroxide (CH) contents, and specific surface area of the hydrated samples. X-ray diffraction studies were also done. The results showed that prepared β-dicalcium silicate is highly reactive. Calcium chloride (1.0 wt%) and gypsum retard the hydration. Possible causes of high reactivity have been discussed.

TL;DR: In this article, the formation of hydrogen bond between protonated pyrazoles and anions provides a sufficient driving force for the directed assembly of an extensive supramolecular frame work.
Abstract: The reaction of 3,5-diphenylpyrazole (PzPh2H) with different inorganic acids affords salts viz., PzPh2H2+·H2PO4− (1), PzPh2H2+·NO3−·H2O (2), PzPh2H2+·Cl− (3), 8PzPh2H2+·4HSO4−·2SO4−2·3H2O (4) and PzPh2H2+·ClO4−·H2O·CH3OH (5) with different structures. The present study demonstrates that the formation of hydrogen bond between protonated pyrazoles and anions provides a sufficient driving force for the directed assembly of an extensive supramolecular frame work. Theoretical studies reveal that with the increase in the strength of the inorganic acid, the hydrogen bond interaction energy increases. Using Gaussview to analyse the optimized geometries obtained at DFT(B3LYP)/6-31G(d,p) level of theory further revealed that the orientation of molecules remained the same both in the solid and gaseous phases.
