Overview

What is she best known for?

The fields of study she is best known for:

  • Organic chemistry
  • Enzyme
  • Ion

Mara G. Freire mostly deals with Ionic liquid, Aqueous solution, Organic chemistry, Extraction and Inorganic chemistry. Her research integrates issues of Phase, Chromatography, Alkyl, Ion and Chemical engineering in her study of Ionic liquid. Her biological study spans a wide range of topics, including Biomolecule and Salt.

The Imide, Binodal and Chemical structure research Mara G. Freire does as part of her general Organic chemistry study is frequently linked to other disciplines of science, such as Environmentally friendly, therefore creating a link between diverse domains of science. Her work on Liquid–liquid extraction as part of general Extraction study is frequently connected to Reusability, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them. Her Inorganic chemistry research includes elements of Dicyanamide, Viscosity, Isobaric process, Trifluoromethanesulfonate and Solubility.

Her most cited work include:

  • Aqueous biphasic systems: a boost brought about by using ionic liquids (509 citations)
  • Aqueous biphasic systems: a boost brought about by using ionic liquids (509 citations)
  • Hydrolysis of Tetrafluoroborate and Hexafluorophosphate Counter Ions in Imidazolium-Based Ionic Liquids† (415 citations)

What are the main themes of her work throughout her whole career to date?

Her scientific interests lie mostly in Ionic liquid, Aqueous solution, Organic chemistry, Extraction and Chromatography. Her Ionic liquid study combines topics from a wide range of disciplines, such as Inorganic chemistry, Alkyl, Ion, Chemical engineering and Solubility. Her work in Inorganic chemistry addresses issues such as Hexafluorophosphate, which are connected to fields such as Tetrafluoroborate.

Her Aqueous solution research incorporates elements of Partition coefficient, Biomolecule, Phase, Polymer and Salt. Her work in the fields of Organic chemistry, such as Imide, Chloride, Pyridinium and Salting out, overlaps with other areas such as Context. Her studies in Extraction integrate themes in fields like Biomass, Separation process, Acetonitrile and Solvent.

She most often published in these fields:

  • Ionic liquid (80.34%)
  • Aqueous solution (61.03%)
  • Organic chemistry (32.76%)

What were the highlights of her more recent work (between 2019-2021)?

  • Aqueous solution (61.03%)
  • Ionic liquid (80.34%)
  • Chromatography (21.38%)

In recent papers she was focusing on the following fields of study:

Mara G. Freire focuses on Aqueous solution, Ionic liquid, Chromatography, Extraction and Adsorption. The various areas that she examines in her Aqueous solution study include Solvent, Inorganic chemistry and Polypropylene glycol, Chemical engineering, Polyethylene glycol. Her Inorganic chemistry research is multidisciplinary, relying on both Ion and Dissociation.

To a larger extent, she studies Organic chemistry with the aim of understanding Ionic liquid. Her work on Fractionation as part of general Chromatography study is frequently linked to Ovalbumin, bridging the gap between disciplines. As part of one scientific family, Mara G. Freire deals mainly with the area of Polymer, narrowing it down to issues related to the Phase, and often Mass transfer.

Between 2019 and 2021, her most popular works were:

  • Aqueous two-phase systems: Towards novel and more disruptive applications (18 citations)
  • Bacterial nanocellulose membranes loaded with vitamin B-based ionic liquids for dermal care applications (13 citations)
  • Enhanced conversion of xylan into furfural using acidic deep eutectic solvents with dual solvent and catalyst behavior (13 citations)

In her most recent research, the most cited papers focused on:

  • Organic chemistry
  • Enzyme
  • Oxygen

Mara G. Freire mainly focuses on Ionic liquid, Aqueous solution, Extraction, Solubility and Nuclear chemistry. Her study with Ionic liquid involves better knowledge in Organic chemistry. Her Aqueous solution research is multidisciplinary, incorporating perspectives in Chemical substance, Polymer, Chromatography, Laccase and Chemical engineering.

Mara G. Freire combines subjects such as Biomass, Cellulose and Dissolution with her study of Extraction. Mara G. Freire interconnects Nanotechnology and Drug delivery in the investigation of issues within Solubility. Her Nuclear chemistry research incorporates themes from Diclofenac Sodium, Effluent, Sewage treatment and Adsorption.
