#MEDPore2025 #tiling nr. 15 (Bahia palace, Marrakech): I guess this counts as solid solution... or stacking disorder #Crystallography #BraggYourPattern
An square grid of coloured square tiles spaced by octagonal terracotta-colour ones. The colour of the square tiles is homogeneous vertically, but changes every two rows, from left to right (brown, brown, white, white, blue, blue, white, white, green, green, white...)

#MEDPore2025 #tiling nr. 14 (Bahia palace, Marrakech): back to multicolour 🟡🟢⚪🔵⚫ #crystallography #BraggYourPattern
Tiling of squares of two different sizes and colours (ochre, blue, green, black), touching at the corners and spaced by white rectangles.

What's better than discussing porous materials in a stunning location? ☀️🌍🧪

Not much! We had an incredible week of inspiring talks and great company at #MedPore2025 in Marrakesh. 🇲🇦

Looking forward to the next edition!

Where did we leave off... #MEDPore2025 #tiling nr. 13 (Bahia palace, Marrakech): simple structure, but with such an elegant terracotta-emerald colour match 😌 #crystallography #BraggYourPattern
A simple tiling of light brown-red octagons joined, in their corners, by tilted dark green smaller tiles.

Taking a day off from posting more #tiling treasures found while attending #MEDPore2025; meanwhile enjoy this shot containing up to 5 different contiguous mosaic structures! 🤩 #crystallography #BraggYourPattern
A passage in the Bahia palace where various complex mosaic combine in different places: stairs, walls, pavement,...

#MEDPore2025 #tiling nr. 12 (Bahia palace, Marrakech): core-shell tiling, interesting 20x20.5 unit cells inside, with two tiny vacancy defects #crystallography #BraggYourPattern
Regular tiling of green squares and white rectangles, framed by another tiling of colourful yellow, green, white and blue squares.

#MEDPore2025 #tiling nr. 11 (Bahia palace, Marrakech): let's go aperiodic with this spectacular 4m, proudly violated by the tiny cheeky cross in the centre #crystallography #BraggYourPattern
Intricate radial tiling with 4m symmetry made of black, blue, green, yellow and white tiles

#MEDPore2025 #tiling nr. 10 (Bahia palace, Marrakech): can I call this 'mesotiling'? I believe so... Another elegant P4m #crystallography #BraggYourPattern
A tiling of large marble squares separated by stripes composed of much smaller, regular green tiles.

#MEDPore2025 #tiling nr. 9 (Bahia palace, Marrakech): egalitarian solution to a metric mismatch 👏🏻 #crystallography #BraggYourPattern
Two chess-board patterns, in white and dark green, meet in a mismatch of their structures. The artist resorted to cutting the tiles symmetrically, sacrificing equal parts for both sides.

#MEDPore2025 #tiling nr. 8 (Bahia palace, Marrakech): a nice and simple Pmm tiling, but #MOF scientists will see something more... 😌 #crystallography #BraggYourPattern
Periodic tiling of yellow-pink and white tiles forming a framework with dark green rhombus shaped gaps as cavities.

#MEDPore2025 #tiling nr. 7 (Bahia palace, Marrakech): they knew the truth on octahedral tilting in perovskites all along... #crystallography #BraggYourPattern #perovskites
Tiling of tilted squares in black, yellow, blue and grey. The empty spaces, with shape of horizontally and vertically oriented rhombuses, are reminiscent of the orthorhombic structure of CsPbBr3 perovskite.

#MEDPore2025 #tiling nr. 6 (cultural outlier at the conference venue): unexpected paracrystal-ish structures on sofa covers #crystallography #BraggYourPattern #StructureDisorder
Cloth displaying decorative tiling of polygons (mostly quadrangular) without repeating sequence of shapes or colours.

#MEDPore2025 #tiling nr. 5 (still conference venue): painted ceiling woodwork reminiscent of Alhambra patterns; P4m symmetry is getting statistically dominant 🧐 #crystallography #BraggYourPattern
Alhambra style woodwork pattern in turquoise, red and gold.

More from Arvind Rajendran at the #MEDPore2025 panel discussion: For gas separations, adsorbents must be good at various things & so “we need a decathlete, not Usain Bolt”!

Selectivity, for example, is important, but so are other parameters like working capacity, cyclic stability, etc…

Advice from Arvind Rajendran at the #MEDPore2025 panel discussion: “Speak to someone who isn’t you”

Wise words!

#MEDPore2025 #tiling nr. 3 (conference venue): P4m (-ish) construction with broken plane group & translational symmetry #crystallography #BraggYourPattern #StructuralDisorder
Complex and colourful Moroccan tiling with a "square" symmetry. All tiles are carefully placed in a highly symmetric and overall periodic fashion, with the exception of the unit cell corners, where slightly tilted tiles arrangements break the periodicity because of their orientation, but not their colours

My walk to work this week at #MEDPore2025 in Marrakech.

Amongst other things, it's been great to meet & chat more to @stecanossa.bsky.social, who also has a similar walk to work.

#MEDPore2025 #tiling nr. 2 (conference venue): gradually broken point symmetry (central 12-fold turning 8-fold and then 2-fold) #crystallography #BraggYourPattern
Colourful tiling showing a central wheel-like radial tiling evolving in symmetry-broken variants going outwards.

Just a week left before heading to Marrakech for #MEDPore2025, where I'll give a lecture -on my birthday! 😶‍🌫️- and co-lead a panel discussion on characterization of #PorousMaterials 🔥 Hope to see many known and new friendly faces! ...and get a healthy overdose of geometrical tilings 🌟
