Overview

What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Oxygen
  • Ion

His primary scientific interests are in Nuclear magnetic resonance spectroscopy, Analytical chemistry, Solid-state nuclear magnetic resonance, X-ray crystallography and Magic angle spinning. His study in Nuclear magnetic resonance spectroscopy is interdisciplinary in nature, drawing from both Apatite, Germanium and Copper. John V. Hanna has researched Analytical chemistry in several fields, including Electric field gradient, Carbon-13 NMR satellite and Carbon-13 NMR.

His research integrates issues of Solid phases, CASTEP and Spectral simulation in his study of Solid-state nuclear magnetic resonance. His work carried out in the field of X-ray crystallography brings together such families of science as Crystallography and Crystal structure. His Magic angle spinning research includes elements of Silane, Calcium, Exfoliation joint and High-resolution transmission electron microscopy.

His most cited work include:

  • Ion exchange in the charge-balancing sites of aluminosilicate inorganic polymers (63 citations)
  • Recent technique developments and applications of solid state NMR in characterising inorganic materials (59 citations)
  • Highly flexible silica/chitosan hybrid scaffolds with oriented pores for tissue regeneration (54 citations)

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

John V. Hanna focuses on Crystallography, Solid-state nuclear magnetic resonance, Analytical chemistry, Inorganic chemistry and Magic angle spinning. His work deals with themes such as X-ray crystallography, Stereochemistry and Copper, which intersect with Crystallography. His Solid-state nuclear magnetic resonance research is multidisciplinary, relying on both Ab initio, Mineralogy, Density functional theory and Chemical shift.

He combines subjects such as Hydrogen, Amorphous solid, NMR spectra database and Nuclear magnetic resonance spectroscopy, Nuclear magnetic resonance with his study of Analytical chemistry. His Inorganic chemistry research is multidisciplinary, incorporating elements of Mesoporous material, Oxygen and Conductivity, Physical chemistry. His study looks at the relationship between Magic angle spinning and topics such as Calcium, which overlap with Simulated body fluid and Sol-gel.

He most often published in these fields:

  • Crystallography (23.08%)
  • Solid-state nuclear magnetic resonance (23.08%)
  • Analytical chemistry (23.72%)

What were the highlights of his more recent work (between 2017-2021)?

  • Solid-state nuclear magnetic resonance (23.08%)
  • Analytical chemistry (23.72%)
  • Magic angle spinning (12.82%)

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

John V. Hanna mainly investigates Solid-state nuclear magnetic resonance, Analytical chemistry, Magic angle spinning, Crystallography and Perovskite. His Solid-state nuclear magnetic resonance research integrates issues from Chemical physics, Bond length, Crystal structure and Density functional theory. His Analytical chemistry study incorporates themes from Deuterium, Heavy water, Formamidinium and Microstructure.

His study with Magic angle spinning involves better knowledge in Nuclear magnetic resonance spectroscopy. The study of Crystallography is intertwined with the study of Boron in a number of ways. His Perovskite study integrates concerns from other disciplines, such as Halide, Nanocrystal, Thermal stability and Hydrogen.

Between 2017 and 2021, his most popular works were:

  • Facile silane functionalization of graphene oxide (36 citations)
  • New Structural Model of Hydrous Sodium Aluminosilicate Gels and the Role of Charge-Balancing Extra-Framework Al (31 citations)
  • Cesium Copper Iodide Tailored Nanoplates and Nanorods for Blue, Yellow, and White Emission (28 citations)

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

  • Organic chemistry
  • Oxygen
  • Ion

The scientist’s investigation covers issues in Ion, Aqueous solution, Perovskite, Dissolution and X-ray photoelectron spectroscopy. His studies deal with areas such as Rietveld refinement, Halide, Nanocrystal, Thermal stability and Oxidation state as well as Perovskite. His research in Dissolution intersects with topics in Sol-gel, Bioactive glass and Polymer.

John V. Hanna interconnects Solid-state nuclear magnetic resonance and Analytical chemistry in the investigation of issues within Scanning electron microscope.
