A novel electrochemical choline oxidase enzyme inhibition biosensor for dichlorvos has been developed based on poly(brilliant cresyl blue) films formed on multiwall-carbon nanotube modified glassy carbon electrodes by fixed potential and potentiodynamic cycling electropolymerisation in acid-dope...

The role of water in the TiO2-based photocatalytic phenomenon is not yet fully understood. The photocatalysis of methylene blue dissolved in propylene carbonate and different concentrations of water was studied. It was observed that the photocatalytic activity of TiO2 (P25 from Evonik) peaks whe...

The compounds: Co3Cr4(PO4)6, Cr(PO3)3 and CoCr2(P2O7)2 were tested for possible application as ceramics and anticorrosive pigments. They were characterized by SEM analysis, determination of particle size distribution and thermal stability. All phosphates were thermally stable up to 1100 °C so t...

The aim of this work is to investigate the luminescence color changes of thermosensitive luminous fibers (TLFs). These TLFs are comprised of rare-earth luminescent materials as the luminescence sources, reversible thermochromic crystal violet lactone (CVL) pigment as the luminescence conversion ...

Maya Blue pigment has attracted considerable attention owing to their extraordinary stability. The growing interest in this field has largely expanded the study of Maya Blue-like pigments. Inspired by Maya Blue, a stable palygorskite/methyl [email protected]2 (PAL/[email protected]2) “Maya Viol...

Novel nontoxic LaAl1-xMnxGe2O7 (0.01 ≤ x ≤ 0.20) violet pigments were synthesized through a conventional solid-state reaction. The crystal structures, optical properties, and color properties of these pigments were investigated. The LaAl1-xMnxGe2O7 (0.01 ≤ x ≤ 0.20) pigments prepared in the ...

Photosynthetic organisms need to sense and respond to fluctuating environmental conditions, to perform efficient photosynthesis and avoid the formation of harmful reactive oxygen species. Cyanobacteria have developed a photoprotective mechanism that decreases the energy arriving at the reaction ...

Aiming towards discovering a solution for the imminent fossil fuel crisis, the research contributes towards the utilisation of orange peel oil as a potential alternative to mineral diesel while strictly adhering to the emission norms. The study reveals the performance, combustion and emissions c...

Four new donor–acceptor based stilbene derivatives were synthesized via Heck coupling reaction. These materials are green light emitters with good fluorescence quantum yield. Furthermore, the emitters show well matched HOMO/LUMO value as bipolar molecule. In addition, they are highly thermally ...

The objective of this work is to investigate the inhibition effects on AGEs formation and the ability of scavenging toxic carbonyls of three stilbenes, resveratrol, oxyresveratrol, and piceatannol. The results showed that the three stilbenes had the activity to inhibit the AGEs formation in BSA-...

Three new prenylated stilbenes, named as cajanusins A-C (1-3), and one new natural product cajanusin D (4), along with six known derivatives (5-10) were isolated from the leaves of Cajanus cajan. Their structures were fully elucidated by means of extensive spectroscopic methods and comparison wi...

A prototype stilbene beta cell has been designed, manufactured, tested, and compared to a plastic scintillator beta cell used for nuclear explosion monitoring of radioxenon. Measurements of the four isotopes of interest show similar responses for both the plastic scintillator and stilbene cell. ...

Bacterial pigments showed potential in various applications but the pigment production is limited due to high cost. This study reports on the optimization of yellowish-orange pigment production by Chryseobacterium artocarpi CECT 8497 in liquid pineapple waste medium using response surface method...

We report the preparation of a series of orange Cr- and Sb-containing TiO2 nano-pigments by the polyol via using triethylenglycol (TEG). Poorly crystallized anatase nanopowders with nominal stoichiometric compositions CrxSbxTi1−2xO2, with 0 ≤ x ≤ 0.2, were obtained by heating at 180 °C a solu...

A new environmental-friendly red-orange ceramic pigment based on the general formula Y2-xPrxZr2-yFeyO7-δ was prepared by polymeric sol-gel method at 1400 °C. The solid solution range with defect fluorite structure was determined by XRD and SEM/EDX. The oxidation states of the dopants were stud...

A hydrazine derived ESIPT active Schiff base, 1-(8-methanylylidene-7-hydroxy-4-methyl-2H-chromen-2-one)-2-(2, 4-dihydroxybenzylidene) hydrazine, L was synthesized and characterized by elemental analysis and by various spectroscopic techniques.
