Adsorption of Basic Dyes onto Natural Clay

open access: yesAdsorption Science & Technology, 2004
The adsorption ability of natural clay towards the removal of basic dyes from aqueous textile solutions was investigated. The equilibrium isotherms were measured and analyzed using the Langmuir model and the experimental results compared with the ...

Thermodynamic investigation of waste cooking oil based hydrogen generation system with chemical looping process

open access: yesSouth African Journal of Chemical Engineering, 2016
The thermodynamic features of hydrogen production via chemical looping reforming of waste cooking oil were studied at atmospheric pressure using Gibbs free energy minimization, accounting for the possibility of coke formation.

Real‐time monitoring of root dielectric properties for assessing crop plant damage caused by foliar application of glyphosate

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.

Photocatalytic Degradation of Polynitrophenols on Various Commercial Suspended or Deposited Titania Catalysts Using Artificial and Solar Light

open access: yesInternational Journal of Photoenergy, 2008
Phenol (PH) and three polynitrophenols (4-nitrophenol (PNP), 2,4-dinitrophenol (DNP), 2,4,6-trinitrophenol (TNP)) were photocatalytically degraded by using titania under either artificial or solar light. These four reactions were chosen as test reactions

Early‐stage health technology assessment of a curative gene therapy for multiple sclerosis

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Multiple sclerosis (MS) is associated with significant early morbidity, reduced life expectancy and substantial healthcare and societal costs. The primary objective of this study is to assess the early cost‐effectiveness potential of a novel gene therapy, IMMUTOL, for MS compared with current high‐efficacy treatment sequences.

Vibrational Circular Dichroism Spectra of 2,5‐Diaminoterephtalate Macrocycles Reveal Distant Vibrational Exciton Coupling

open access: yesChemistry – A European Journal, EarlyView.
The energy level diagrams for the ν(C═O) and the δ(N─H) vibrations, resulting of combining in‐phase and out‐of‐phase modes on the basis of their local symmetries, was built by applying the exciton coupling theory to a new class of chiral macrocycles, based on the 2,5‐diaminoterephthalate scaffold.

Chiral Dipicolinamide‐Based Push–Pull π‐Conjugated Systems as Nonreciprocal Circularly Polarized Luminescence Emitters

open access: yesChemistry – A European Journal, EarlyView.
This work presents the synthesis and characterization of chiral dipicolinamide push–pull fluorophores. While possessing similar photophysical properties in solution, their solvent‐annealed thin films exhibit unexpected, nonreciprocal chiroptical activity in both absorption and emission, including a complete inversion of the chiroptical profile upon ...

Potenzial außerschulischer Lernorte zur Förderung transversaler Kompetenzen

open access: yesCHEMKON, EarlyView.
Transversale Kompetenzen wie Kommunikation, Kollaboration, kritisches Denken und Entscheidungsfindung sind zentral für schulischen Erfolg, berufliche Handlungsfähigkeit und gesellschaftliche Teilhabe. Dennoch werden diese Kompetenzen im schulischen Kontext bislang häufig nur niederschwellig gefördert.

Assessment of the effects of microwave‐produced biodiesel blends on electric generator performance and emissions

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Biodiesels are emerging as alternatives to diesel fuel. However, to be a feasible solution, biodiesels must meet strict criteria including high efficiency and minimal environmental impact. The current study focuses on evaluating ethyl ester biodiesel and its blends with diesel fuel to assess their potential.
