Overview

What is she best known for?

The fields of study she is best known for:

  • Botany
  • Organic chemistry
  • Ecology

Helena Pereira mainly focuses on Lignin, Botany, Horticulture, Cork and Chemical composition. Helena Pereira has researched Lignin in several fields, including Composition, Cellulose, Pulp and paper industry and Pyrolysis. Her Botany study combines topics from a wide range of disciplines, such as Pulp and Kraft process.

Her Horticulture research includes themes of Pulpwood, Genetic variation and Eucalyptus globulus. Her work in the fields of Quercus suber overlaps with other areas such as Understory. The various areas that Helena Pereira examines in her Chemical composition study include Activated carbon, Softwood, Aqueous solution and Nitrogen.

Her most cited work include:

  • Effects of short-time vibratory ball milling on the shape of FT-IR spectra of wood and cellulose (724 citations)
  • Wood modification by heat treatment: a review. (571 citations)
  • Cork : biology, production and uses (271 citations)

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

Her primary scientific interests are in Cork, Botany, Lignin, Quercus suber and Bark. In her research on the topic of Cork, Ferulic acid and Chromatography is strongly related with Suberin. Her Horticulture research extends to the thematically linked field of Botany.

Her Horticulture research includes elements of Pulpwood and Pinus pinaster. Her Lignin research is multidisciplinary, relying on both Composition, Food science, Pulp and paper industry and Chemical composition. Her work in Pulp and paper industry addresses issues such as Cellulose, which are connected to fields such as Hydrolysis.

She most often published in these fields:

  • Cork (36.67%)
  • Botany (30.49%)
  • Lignin (25.80%)

What were the highlights of her more recent work (between 2016-2021)?

  • Lignin (25.80%)
  • Cork (36.67%)
  • Bark (18.12%)

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

Helena Pereira focuses on Lignin, Cork, Bark, Suberin and Botany. Her studies in Lignin integrate themes in fields like Composition, Cellulose, Food science, Fractionation and Proanthocyanidin. She is interested in Quercus suber, which is a branch of Cork.

In Bark, Helena Pereira works on issues like Horticulture, which are connected to Wall thickness. Her Suberin research also works with subjects such as

  • Chemical composition and related Eucalyptus,
  • Gallic acid which is related to area like Sieve tube element. Helena Pereira studies Cell wall which is a part of Botany.

Between 2016 and 2021, her most popular works were:

  • Cynara cardunculus L. as a biomass and multi-purpose crop: A review of 30 years of research (53 citations)
  • Improvement of gasification performance of Eucalyptus globulus stumps with torrefaction and densification pre-treatments (37 citations)
  • Potential of Eucalyptus globulus industrial bark as a biorefinery feedstock: Chemical and fuel characterization (34 citations)

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

  • Botany
  • Organic chemistry
  • Ecology

Helena Pereira spends much of her time researching Lignin, Bark, Food science, Suberin and Cork. Her studies in Lignin integrate themes in fields like Composition, Fractionation, Pulp and paper industry and Chemical composition. Her Bark research integrates issues from Eucalyptus, Picea abies, Acacia and Cellular material.

Her Food science research is multidisciplinary, incorporating perspectives in Cellulose, Hydrolysis, Phenols, Proanthocyanidin and Monosaccharide. Her Suberin study introduces a deeper knowledge of Botany. Her Cork research is mostly focused on the topic Quercus suber.
