Overview

What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Redox
  • Ion

George R. Helz mainly focuses on Inorganic chemistry, Sulfide, Molybdenum, Environmental chemistry and Aqueous solution. His Inorganic chemistry study incorporates themes from Polysulfide, Pyrite, Kaolinite and Solubility. His Sulfide study frequently links to adjacent areas such as Trimer.

His research integrates issues of Amorphous solid, Mineralogy and Sorption in his study of Molybdenum. George R. Helz has researched Environmental chemistry in several fields, including Reaction conditions, Effluent and Sewage treatment. His studies in Molybdate integrate themes in fields like Sulfide minerals and Anoxic waters.

His most cited work include:

  • Mechanism of molybdenum removal from the sea and its concentration in black shales: EXAFS evidence (604 citations)
  • Aquatic and Surface Photochemistry (456 citations)
  • Molybdenum(VI) speciation in sulfidic waters; stability and lability of thiomolybdates (444 citations)

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

His primary areas of investigation include Inorganic chemistry, Environmental chemistry, Sulfide, Sulfur and Estuary. His work deals with themes such as Copper sulfide, Polysulfide, Voltammetry and Solubility, which intersect with Inorganic chemistry. His Environmental chemistry research is multidisciplinary, relying on both Seawater, Sulfate, Chlorine and Effluent.

His studies deal with areas such as Precipitation, Molybdenum, Mineralogy, Anoxic waters and Copper as well as Sulfide. George R. Helz has included themes like Sulfide minerals and Pyrite in his Molybdenum study. His Estuary study combines topics from a wide range of disciplines, such as Contamination, Sediment and Continental crust.

He most often published in these fields:

  • Inorganic chemistry (37.10%)
  • Environmental chemistry (33.06%)
  • Sulfide (27.42%)

What were the highlights of his more recent work (between 2005-2019)?

  • Sulfide (27.42%)
  • Inorganic chemistry (37.10%)
  • Environmental chemistry (33.06%)

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

George R. Helz focuses on Sulfide, Inorganic chemistry, Environmental chemistry, Seawater and Nanoparticle. His Sulfide research is multidisciplinary, incorporating perspectives in Solubility equilibrium, Sulfur, Aqueous solution and Mineralogy. His Inorganic chemistry course of study focuses on Iron sulfide and Colloid.

His Environmental chemistry research incorporates elements of Sediment, Estuary, Sulfate and Molybdenum. The study incorporates disciplines such as Early Pleistocene and Sulphur isotope in addition to Molybdenum. His Seawater research is multidisciplinary, incorporating elements of Deposition, Shewanella oneidensis, Water column, Rhenium and Anoxic waters.

Between 2005 and 2019, his most popular works were:

  • New model for molybdenum behavior in euxinic waters (226 citations)
  • Thermodynamic model for arsenic speciation in sulfidic waters: A novel use of ab initio computations (99 citations)
  • What regulates rhenium deposition in euxinic basins (46 citations)

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

  • Organic chemistry
  • Redox
  • Ion

George R. Helz mostly deals with Sulfide, Inorganic chemistry, Seawater, Water column and Environmental chemistry. His study in Sulfide is interdisciplinary in nature, drawing from both Molybdenum, Mineralogy, Saturation, Solubility equilibrium and Aqueous solution. His Inorganic chemistry research integrates issues from Colloid and Sulfur.

His work is dedicated to discovering how Seawater, Anoxic waters are connected with Rhenium, Partition coefficient, Coprecipitation, Authigenic and Hydrology and other disciplines. The Water column study combines topics in areas such as Estuary, Total organic carbon and Polysulfide. His Environmental chemistry study combines topics in areas such as Drainage basin and Sediment.
