PoreXpert update

20 July 2022

In response to requests from our current users, a new update has been released.  It includes improved stability for remote working in a corporate environment, further automation of the identification of void clusters, corrected data handling for non-English environments, and better display of results on the Operations list.  A full list of changes is shown on the Change Log page.  The installer for the update (version 2-1-710) can be downloaded via the User Pages , and there are full instructions on the Software support > Installation page.

Nanopores to macropores in nuclear reactor graphite and tight-oil shale

6 July 2022

Are you trying to understand the behaviour of pore fluids in a material in which voids of all sizes, from nanopores to macropores, are completely mixed up and inter-dependent ?  Are you flummoxed as to how to study nanopores when mercury porosimetry cannot get to a high enough pressure to intrude them ?  Or are you trying to improve on the current crude models used to calculate relative permeability ? Then take a look at the PowerPoint presentation that we gave to the Royal Society of Chemistry Porous Materials Interest Group in Glasgow, UK in June, available from the Downloads > Applications page.  Extra text has been added to compensate for the absence of an oral commentary, and for your entertainment it includes two movies – one a trip through a real tight-oil shale from a fracking reservoir measured using FIB-SEM as illustrated, and another a trip through a PoreXpert virtual pore network.

PoreXY – the new data pre-processor

17 June 2022

We are pleased to announce the arrival of PoreXY, the new data pre-processor for PoreXpert.  It allows you to trim and thin your data to make it suitable for direct entry into PoreXpert, and also gives you the bulk modulus of the solid phase of your sample.  The beta release is available free of charge to all current users of PoreXpert – just log in as a website user, and download the installer.  Full details are available from its Help system.

Presentation on latest developments

6 May 2022

Prof. Peter Matthews is giving a presentation at the Royal Society of Chemistry Porous Materials conference in Glasgow, UK, 13th and 14th  June, entitled ‘Nanopores integrated with macropores:  modelling weight loss in nuclear reactor cores and the relative permeability of tight-oil shale’.  It will describe the latest developments and applications of PoreXpert, which are also applicable to other complex porous materials.

New batch files

26 March 2022

In response to a request from a current user who is modelling 40 samples with large (25x25x25) unit cells, additional batch files have been uploaded to the Downloads | Batch files table.

On-line training

21 February 2022

Inverse modelling tends to amplify any errors, so on-line training is highly recommended.  We have just completed our latest course, which according to the client provided “extremely informative and detailed training”.  Please see the Software Support | Training page for details.

Bone scaffold modelling

25 January 2022

The Departamento de Farmacología, Farmacia y Tecnología Farmacéutica of the Universidade de Santiago de Compostela, Spain has been using PoreXpert to model bone scaffolds.  So far, they have used PoreXpert version 1, as detailed in a Technical Application Note and in the testimonials at the bottom of this home page.  They are currently upgrading to version 2, which will allow them to generate much larger and even more realistic void network models.

Porotec, Microtrac and Formnext

1 November 2021

Porotec GMBH has merged with Retsch Technologies, under the ownership of BEL, and is now Microtrac Retsch. They have taken over the Thermo Fisher mercury porosimeter product line to produce an even better porosimeter – the BELPORE. The next update of PoreXpert will read in BELPORE data files automatically. Meanwhile if you would like some publicity material and a demonstration of PoreXpert, please visit the Microtrac Retsch stand at the Formnext show on 16 – 19 November 2021 in Frankfurt / Main.

Data thinner for mercury porosimetry

28 September 2021

At the request of one of our current users, a Python script is now available on the software downloads page for thinning output from mercury porosimeters for input to PoreXpert.  Although PoreXpert can automatically input data from many instruments, this pre-processing speeds up the simplex convergence algorithm and equally weights all points on the intrusion curve, whereas if data is input directly, important points of inflexion tend to be under-weighted statistically.

Special core analysis for unconventional reservoirs

13 September 2021

We have extended the use of PoreXpert to the calculation to special core analysis, specifically the simulation and calculation of relative permeability in tight-oil shale.  A PowerPoint presentation is available on the new Downloads | Application notes page.
