Polyimides prepared from 3,5-diamino benzo trifluoride [PDF]

, 1993
High performance, thermooxidatively stable polyimides are prepared by reacting aromatic diamines with pendant trifluoromethyl groups and dianhydrides in an amide solvent to form a poly(amic acid), followed by cyclizing the poly(amic acid) to form the ...

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 ...

Remoção de compostos fenólicos de soluções aquosas utilizando carvão ativado preparado a partir do aguapé (Eichhornia crassipes): estudo cinético e de equilíbrio termodinâmico

Química Nova, 2014
Activated carbon was produced from the water hyacinth (CAA) by impregnation with ZnCl2 (1:2), followed by pyrolysis at 700 ºC, under N2. CAA was used for the adsorption of phenol, m-cresol and o-cresol from aqueous solutions, using batch adsorption.

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.

Polyenamines from aromatic diacetylenic diketones and diamines [PDF]

, 1987
The synthesis and characterization of several polyenamine ketones are discussed wherein conjugated diacetylenic diketones and aromatic diamines are used as a route to the formation of high molecular weight polyenamine ketones which exhibit good ...

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 ...

Electrochemical Simultaneously Determination of Phenol and o- Cresol in Water Based on ZnO Nanosheets

International Journal of Electrochemical Science, 2016
Phenol and o-cresol are two organic contaminants largely produced by many industries and could potentially harmful people and environment. In this study, we proposed an electrochemical approach that could simultaneously determination of phenol and o ...

N-(3-ethynylphenyl)maleimide [PDF]

, 1990
Acetylene terminated aspartimides are prepared using two methods. In the first, an amino-substituted aromatic acetylene is reacted with an aromatic bismaleimide in a solvent of glacial acetic acid and/or m-cresol.

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 ...
