Peter Stilbs (born 1 June 1945) is an emeritus professor in physical chemistry at the Royal Institute of Technology (KTH) in Stockholm, Sweden. [1]

Stilbs earned a master's degree in chemical engineering from the Lund Institute of Technology at Lund University in 1969, and a Ph.D. in physical chemistry in 1974. He served as a research assistant in physical chemistry at Uppsala University from 1976 to 1982, and as an assistant professor from 1982 to 1986. In 1986 he became full professor in physical chemistry at the Royal Institute of Technology in Stockholm. His main fields of research are the techniques and applications of nuclear magnetic resonance (NMR), in particular using pulsed-gradient spin-echo methodology for studying molecular self-diffusion and electrophoretic movement. [2] The work (almost 200 peer-reviewed papers) has been summarised in a 1987 review article "Fourier Transform Pulsed-Gradient Spin-Echo Studies of Molecular Diffusion" (which has almost 2000 citations to date) and a more recent monograph "Diffusion and Electrophoretic NMR", which was published in 2019. [3]

Stilbs has also been active in the debate on global warming. He has criticised the view that there is a scientific consensus on the attribution of recent climate change, and described the climate projections conducted by the Intergovernmental Panel on Climate Change (IPCC) as inadequate and misleading. [4] [5] In September 2006 he was chairman of an international seminar at the Royal Institute of Technology labelled Global Warming – Scientific Controversies in Climate Variability, where both critics and supporters of the theory of man-made global warming were invited.

<span class="mw-page-title-main">Molecular diffusion</span> Thermal motion of liquid or gas particles at temperatures above absolute zero

Molecular diffusion, often simply called diffusion, is the thermal motion of all particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of higher concentration to one of lower concentration. Once the concentrations are equal the molecules continue to move, but since there is no concentration gradient the process of molecular diffusion has ceased and is instead governed by the process of self-diffusion, originating from the random motion of the molecules. The result of diffusion is a gradual mixing of material such that the distribution of molecules is uniform. Since the molecules are still in motion, but an equilibrium has been established, the result of molecular diffusion is called a "dynamic equilibrium". In a phase with uniform temperature, absent external net forces acting on the particles, the diffusion process will eventually result in complete mixing.

<span class="mw-page-title-main">Spin echo</span> Response of spin to electromagnetic radiation

In magnetic resonance, a spin echo or Hahn echo is the refocusing of spin magnetisation by a pulse of resonant electromagnetic radiation. Modern nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) make use of this effect.

<span class="mw-page-title-main">Spin–spin relaxation</span>

In physics, the spin–spin relaxation is the mechanism by which Mxy, the transverse component of the magnetization vector, exponentially decays towards its equilibrium value in nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). It is characterized by the spin–spin relaxation time, known as T2, a time constant characterizing the signal decay. It is named in contrast to T1, the spin–lattice relaxation time. It is the time it takes for the magnetic resonance signal to irreversibly decay to 37% (1/e) of its initial value after its generation by tipping the longitudinal magnetization towards the magnetic transverse plane. Hence the relation

A Benchtop nuclear magnetic resonance spectrometer refers to a Fourier transform nuclear magnetic resonance (FT-NMR) spectrometer that is significantly more compact and portable than the conventional equivalents, such that it is portable and can reside on a laboratory benchtop. This convenience comes from using permanent magnets, which have a lower magnetic field and decreased sensitivity compared to the much larger and more expensive cryogen cooled superconducting NMR magnets. Instead of requiring dedicated infrastructure, rooms and extensive installations these benchtop instruments can be placed directly on the bench in a lab and moved as necessary. These spectrometers offer improved workflow, even for novice users, as they are simpler and easy to use. They differ from relaxometers in that they can be used to measure high resolution NMR spectra and are not limited to the determination of relaxation or diffusion parameters.
