The production of platform chemicals via carbon negative technologies will play an important role in global efforts to mitigate climate change. Succinic acid biorefineries are commercially mature carbon negative technologies that are plagued with large waste streams in the form of hemicellulose ...

This study investigated the dielectric properties of sodium alginates and carrageenans in water at frequencies between 100 MHz and 20 GHz in regard to water-hydrocolloid interactions via acidic functional groups. Both sodium alginates and carrageenans showed conduction loss at lower frequencies ...

Barley (Hordeum vulgare) and rice (Oryza sativa) differ greatly in their salt tolerance, although both species belong to the Poaceae family. To understand the mechanisms in the difference of salt tolerance between the two species, the responses of ionome, metabolome and gene expression of Na and...

Impact of cations in a fermentation broth by calcium, potassium, or sodium hydroxide was investigated. Acid hydrolysate from lignocellulosics is generally neutralized with calcium hydroxide, which is an insoluble salt (known as gypsum) produced in the process. Also, adsorption of monosaccharides...

Dye diffusion in color paste plays a crucial role in textile printing. This work is to explore different influences of process parameters on the apparent diffusion of an acid dye (C.I. Acid Blue 7) in sodium alginate paste at the first time, with a novel and specially developed method by employi...

A xanthouronic acid sodium salt called xanthouronan was produced from xanthan by regioselective oxidation with NaOCl/NaBr using 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO) as catalyst. The efficiency of the one pot TEMPO-mediated oxidation was confirmed by HPAEC-PAD, 13C NMR, and FT-IR. ...

β-(1,3)-Polyglucuronic acid sodium salt produced by the regioselective oxidation of β-(1,3)-glucan have been studied for its biological impact as putative slimming agent. This β-(1,3)-polyglucuronic acid sodium salt was synthesized using the conventional 2,2,6,6,-tetramethylpiperidine-1-oxyl ...

Various metal cations exchanged Y zeolites were prepared via the exchange of NaY zeolite with aqueous solutions containing K+, Ca2+, Cu2+, La3+ and Ce3+ cations, respectively. The influence of the extra-framework cations nature of these ion-exchanged Y zeolites on their adsorption performance fo...

Halo-olefinic impurities in 1,1,1,3,3-pentafluoropropane (HFC-245fa) product used as blowing agents, etc. could damage the human body and must be removed. Activated carbon was treated by HCl, HNO3 and NaOH, respectively. The adsorptive performance of unmodified and modified activated carbons for...

Plants containing pyrrolizidine alkaloids (PAs) are widespread throughout the world and are the most common poisonous plants affecting livestock, wildlife, and humans. PAs require metabolic activation to form reactive dehydropyrrolizidine alkaloids (dehydro-PAs) that are capable of alkylating ce...

There are 660 pyrrolizidine alkaloids (PAs) and PA N-oxides present in the plants, with approximately half being possible carcinogens. We previously reported that a set of four PA-derived DNA adducts is formed in the liver of rats administered a series of hepatocarcinogenic PAs and a PA N-oxide....

The ability of several N-phenyl-1H-pyrazole-4-carboxamide derivatives and other pyrazoles opportunely modified at the positions 3, 4 and 5, to reduce the formation of the biofilm in some Staphylococcus aureus strains (ATCC 29213, ATCC 25923 and ATCC 6538) were investigated. All the tested compou...

In this work we present equilibrium and dynamic surface tension together with dilational elasticity data for dodecyltrimethylammonium bromide in the presence of λ-carrageenan, a sulfated polysaccharide extracted from algae. The critical aggregation concentration and (CAC) and critical micellar ...

(2E)-1-(2,4-Dichlorophenyl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one is synthesized by using 2,4-dichloroacetophenone and 3,4,5-trimethoxybenzaldehyde in ethanol. The structure of the compound was confirmed by IR and single crystal X-ray diffraction studies. FT-IR spectrum of (2E)-1-(2,4-dichlo...

The heterocyclic compounds have been extensively reported for their bioactivity potential. The current research work reports the synthesis of some new multi-functional derivatives of 2-furoic piperazide (1; 1-(2-furoyl)piperazine). The synthesis was initiated by reacting the starting compound 1 ...

Strategically modified4-(diethylamino)-2-(pyridin-2-ylmethoxy)benzaldehyde appended BODIPY-based probe N,N-SP-BPY detects aspartic acid (Asp) and glutamic acid (Glu) by inhibition of Photoinduced electron transfer (PET) process in water. The probe shows considerable and rapid fluorescence enhanc...

The title compound, 1-acetyl-3-(2,4-dichloro-5-fluoro-phenyl)-5-phenyl-pyrazoline, has been synthesized and characterized by elemental analysis, IR, UV–vis and X-ray single crystal diffraction. Density functional (DFT) calculations have been carried out for the title compound by using B3LYP met...

Photochromic E,Z-isomerization in 4-styryl-1,8-naphthalimides does not significantly affect their fluorescent properties and can be neglected when choosing them as navigators and biological markers.

Four newly-synthetized styryl-phenanthroline derivatives were found to exhibit great acidochromism starting from neutral pH values down to negative H0. The aqueous solution of all of the four molecules features a yellow color at nearly neutral pH, but when the acidity of the solution increases, ...
