Dr Beau Webber - Personal home page
I am the director of a micro-sme nano-science and nano-metrology research company Lab-Tools Ltd. , that also develops cutting-edge instrumentation.
These properties can be used to probe the properties of ordinary
materials like house roof tiles. (How frost durable are they ?
What pore sizes do they have ?) These techniques can also be used
to investigate subjects as diverse as the behaviour of oil and
water in rocks, as well as the properties of the rocks themselves,
the behaviour of high-performance (nano-material) batteries and
the adsorption and release properties drug molecules in small
pores. Important recent applications include both oil in sales and
carbonate rocks, and studying the properties of biochars,
for carbon sequestration and soil improvement.

Recently I have used StereoPanorama to look at full-colour
stereo-pairs of comet P17/Holmes, that I have created from others'
superb photos. The stereo-effect just comes from the comet motion,
but it seems to help the brain separate the delicate comet corona
and tail from the background stars.
Here is an example pair created from :

I study structured matter, mainly on the nano- to meso- to micro-scale: from about 1 Å up to a few µm, primarily using techniques based on NMR and neutron scattering.
I do this both from a wish to study the novel properties of the matter, and also from a wish to apply this knowledge to the science of metrology over this nano-scale to micro-scale range.
In particular, I study the behaviour of liquids in confined geometry, both at and near the surfaces of substrates. In both cases the physical properties of liquids are modified, sometimes substantially.
First I study the properties of liquids in well characterised porous materials, such as sol-gel silicas, and the templated MCM and SBA-15 silicas.
Then I apply this understanding to investigate the properties of uncharacterised porous materials, such as porous carbons, biochar, fired or un-fired clays, marine sediments, oil-bearing rocks, meteorite fragments ....
In my research, I specialise in combining results from different measuring techniques, using computer based models, and also in designing novel measurement protocols.
The prime experimental techniques I use are :
My research home page is at Research home and my publications are listed at Beau Webber's publications .
I am currently
director of the micro/SME company Lab-Tools Ltd. www.Lab-Tools.com
- specialising in contract nano-to micro-scale analyses of structured liquids and solids (pore-size analysis).
The main technique used is NMR Cryoporometry, which is closely related to the technique of gas adsorption, but is measured using a liquid rather than a gas. The technique originated at Kent University and has been extensively developed by Lab-Tools : Nuclear Magnetic Resonance Cryoporometry J. Mitchell, J. Beau W. Webber and J.H. Strange. Physics Reports, 461, 1-36, 2008. DOI: 10.1016/j.physrep.2008.02.001
The studies we perform are relevant to :
For this scientific research work I have to design instrumentation that otherwise would not exist, thus the Lab-Tools company also has an instrumentation division .
I have been
designing NMR and computerised instrumentation and their software
since 1970. I designed and built NMR spectrometers in the 1970 and
1980s (sold in the UK and internationally, and some components
still performing cutting edge research). I have worked with and
built hardware and software interfaces for DEC PDP 8 and 11s,
worked on an Apl to C compiler ( The APLc compiler project ) since
the days of the VAX 11/750, designed and built a set of
rack-mounted, modular Motorola 6802 based transient data
capture/averager/processor microcomputers (using dual-ported
memories) in the early 1980s, for NMR data capture and analysis. (Capturing
transient data using a microprocessor based system. John
Beausire Webber, Master of Science Dissertation, 80 p, 88 p of
computer printout. Physics, University of Kent, UK, 1979.)
In the 1990s I designed and built a dedicated scanning NMR
Cryoporometer, using one of my NMR spectrometers, IEEE 448
instrumentation and LabVIEW software on a PC (only recently
switched off). (Characterising Porous Media. John
Beausire Wyatt Webber, Ph.D. Thesis, xvii, 305 p, Physics,

I have been designing with FPGAs since 1990, and am currently
rebuilding the instrumentation in my NMR lab using credit-card
sized USB interfaced FPGA based modules of my own design. I am
finding the credit-card Linux computer the Raspberry
Pi quite useful for web serving applications, and am looking
towards applying Dyalog's new free Apl
for the Raspberry Pi. I am also working towards the next
generation instrumentation, and developing the next
generation of digital NMR radio-frequency approaches based on the
newly available of multiple processors on a chip, such as the XMOS devices and
Epiphany chip, again both credit card sized boards.
In my research I make heavy use of the array processing language Apl : I first met APL in the pages of Byte Magazine (August 1977, Working with APL), and realised that it was just what a research physicist needed for the interactive manipulation of arrays of experimental data. I made various improvements to Apl\11 on the VAX 750 and 1982 I added the multi-tasking facilities "Julian time stamp": 'jts' and 'pipe' to Apl\11, to give easy access to the Unix shell. (Pipe is now incorporated into IBM's APL2). I later added these and the more generic 'spawn' to the APL to C translator aplc, implementing in 1999 interactive screen-based neutron-scattering data analysis tools, interfacing the Apl to postscript and tcl/tk windows : DoD22 : Show and Analyse Area Multidetector Data for ILL D22
I now use APL
(particularly APLX) for interactive multi-tasking control of my
NMR apparatus and designing the GUI interfaces - it is
interactive which means both rapid development, and that it is
ideal for day-to-day use in the lab, for controlling the
instrumentation and analysing the data, with APL interacting
directly with the FPGA based instruments.
I have recently re-designed an increasing amount of my laboratory instrumentation, and it is now mostly based on field-programmable gate-arrays (FPGAs), with APL interacting directly with the FPGA based instruments over the USB bus - see APLX Version 4, from the viewpoint of an experimental physicist , http://www.lab-tools.com/instrumentation and for videos and inside information on some of the techniques I use in my fpga designs see FPGA Modular Firmware Skeleton for multiple instruments - Morph-IC-II, YouTube videos.Currently I am having good success in porting the APL to C translator aplc to soft processors such as the Altera Nios II, and a range of the new credit-card sized machines, including the Linux computer the Raspberry Pi, the multi-core XMOS devices and Adapteva's Parallella with multi-core Epiphany chip. I currently manage the APL Parallel Programming section of the Adapteva Parallella Forum, where there is a discussion on the ongoing progress regarding the latter case. See their Kickstarter update.
