•Energy density improvement through PCM was tested in an experimental water tank.•PCM-spheres have low thermal conductivity which makes difficult to melt the PCM.•Significant amount of PCM leakage was observed leading to a laboratory analysis.•External coating is recommended to ensure the PCM stability inside the spheres.

Mechanical stratigraphy controls the growth patterns and dimensions of relatively small normal faults, yet how it influences the development of much larger structures remains unclear. Here, we use 3D seismic reflection data from the Outer Kwanza Basin, offshore Angola to constrain the geometry and kinematics of several normal faults formed in a deep‐water clastic succession. The faults are up to 6.3‐km long and 1.9‐km tall and have up to 44 m of throw. Aspect ratios and lower‐tip throw gradients are greater for faults that terminate downward at a c. 100 m thick, mass‐transport complex (MTC; up to 5.2 and 0.12) than for those that offset it (up to 2.7 and 0.01). Faults that offset the MTC invariably have >30 m of throw. Based on their geometric properties and throw patterns, we interpret that the faults nucleated above the MTC and propagated down toward it. Upon encountering this unit, which we infer behaved in a more ductile manner than encasing strata, tip propagation was halted until tip stresses were sufficiently high (corresponding to minimum throw of c. 30 m) to breach it. Faults with smaller throw were unable to breach the MTC. We argue that using only geometric criteria to determine fault growth patterns can mask the significant control mechanical stratigraphy has on fault kinematics. Mechanical stratigraphy is therefore a key control on the growth of large, seismic‐scale normal faults, in a similar way to that observed for far smaller structures. Mechanical stratigraphy and fault interaction control the extent to which faults adhere to displacement–length scaling relationshipsFault growth and displacement–length relationships must be considered in context of local controls to be adequately describedDetailed kinematic analysis on faults developing within the same overall tectono‐stratigraphic setting can shed light on the kinematics of faults that do not reach the free surface Mechanical stratigraphy and fault interaction control the extent to which faults adhere to displacement–length scaling relationships Fault growth and displacement–length relationships must be considered in context of local controls to be adequately described Detailed kinematic analysis on faults developing within the same overall tectono‐stratigraphic setting can shed light on the kinematics of faults that do not reach the free surface

A personal narrative is presented which explores the author's experience of searching for the possibilities of using natural dyes in their mill production.

The article pays tribute to dyer Jill Goodwin. It is noted that Goodwin wrote the book "A Dyer's Manual," after being involved in dyeing for 50 years at her family farm in Essex, England, and that the book includes acknowledgments to libraries, museums, and experts in dyeing throughout England. The author reports on the enthusiastic response and demand of the book and presents positive feedback from various dyers and others involved in the textile industry including dyeing author Jenny Dean, dye and indigo expert Jenny Balfour-Paul, and dyer John Edmonds.

Information is presented about the International Colour Congress in Iowa in the U.S. In addition to full-time dyers there were chemists, social anthropologists, economists, and historians that attended the natural dyes conference. Dyes from aphids, avocados, mushrooms, and lichen were discussed, as well as more conventional dyes.

An obituary is presented for Keith Rees, senior craftsmen at the Welsh National Museum at Dre-fach Felindre in Wales.
