Ocean acidification at the crossroads I: Harmonizing unpurified and purified meta‐cresol purple spectrophotometric pHT measurements based on absorbance data

Limnology and Oceanography: Methods, EarlyView.
Abstract Consistent monitoring of seawater spectrophotometric pH on the total hydrogen ion scale (pHT) has been questioned by an evolving method, with changes in parameterization and the purity of the meta‐cresol purple (mCP). Using real seawater samples, we demonstrate that spectrophotometric pHT measurements obtained with unpurified (UNPUR) and ...

Removal of Phenol and o-Cresol by Adsorption onto Activated Carbon

E-Journal of Chemistry, 2008
A commercial activated carbon was utilized for the adsorptive removal of phenol and o-cresol from dilute aqueous solutions. Batch mode adsorption studies were performed by varying parameters such as concentration of phenol solution, time, pH and ...

Thermodynamic parameters of bonds in glassy materials from viscosity-temperature relationships [PDF]

, 2007
Doremus's model of viscosity assumes that viscous flow in amorphous materials is mediated by broken bonds (configurons). The resulting equation contains four coefficients, which are directly related to the entropies and enthalpies of formation and motion

Redox‐Active and Electrochromic Aromatic Poly(Ether‐Imide)s With Carbazole‐Triphenylamine Chromophores

Journal of Polymer Science, EarlyView.
A novel ether‐bridged dianhydride monomer based on a carbazole‐triphenylamine (CzTPA) unit has been successfully synthesized, resulting in the development of electroactive and electrochromic poly(ether imide)s that incorporate CzTPA chromophores within the polymer chain.

Biodegradation of a high-strength wastewater containing a mixture of ammonium, aromatic compounds and salts with simultaneous nitritation in an aerobic granular reactor [PDF]

, 2016
Long-term operation (390 days) of a continuous airlift reactor with aerobic granular biomass was successfully applied to treat a highly complex wastewater composed of: ammonium (1000 mg N L⁻¹), o-cresol (100 mg L⁻¹), phenol (100 mg L⁻¹, quinoline (50 mg ...

Development of a Novel Polyleucine‐Based Immunopotentiator for Subunit Vaccines Against Group A Streptococcus

Small, EarlyView.
Self‐assembling amphiphilic peptide L15K6 is used as a novel immunoadjuvant for the development of a Group A Streptococcus vaccine. Robust antigen‐specific IgG responses are generated and manage to kill isolated strains of Group A Streptococcus. Cellular and bulk RNA sequencing data reveals that L15K6 regulates immune responses potentially through TLR ...

Pollination‐related plant traits under environmental changes: Seasonal and daily mismatches produce temporal constraints

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollination is a key tenet of ecosystem sustainability and food security, but it is threatened by climate change. While many studies investigated the response of plant‐pollination traits to temperature, few attempted multifactorial and integrative approaches with ...
