Oh well huh, speaking of substrates and Egyptian etc.: here's a brand new article proposing a former Afrasian branch in the Balkans, substratal to Proto-Indo-European

Abstract

Hydroponic technology has many benefits that it is highly productive and conserves water and land most especially if natural resources are scarce. Normally, plants grow inside a greenhouse that controls temperature, light, water and nutrition. The study was conducted to evaluate the performance of different growing substrates on lettuce under a non-circulating hydroponics system. It was conducted at Cagayan State University – Piat Campus from September to October 2019. The Completely Randomized Design (CRD) with four replications was used to test the following treatments: T1 – Rockwool, T2– Coco peat, T3 – Carbonized Rice Hull (CRH) and T4 – Sawdust. Results show that plants under coco coir (T2)–obtained the tallest and longest roots while the most number of leaves and heaviest fresh biomass was registered in rock wool (T1). In terms of water pH, the result revealed no significant differences among treatment means. In the absence of rock wool, the coco coir can be used as an alternative as growing substrates for a non-circulating hydroponics system since they did not differ significantly.

High-Performance Laser Fabrication Breakthrough Promises Low Cost Lasers

Lasers grown on microelectronics-compatible silicon are important step toward low-cost, smart, integrated mid-infrared photonic sensors.

For the first time, researchers have fabricated high-performance mid-infrared laser diodes directly on microelectronics-compatible silicon substrates. The new lasers could enable the widespread development of low-cost sensors for real-time, accurate environmental sensing for applications such as air pollution monitoring, food safety analysis, and detecting leaks in pipes.

“Most optical chemical sensors are based on the interaction between the molecule of interest and mid-infrared light,” said research team leader Eric Tournié from the University of Montpellier in France. “Fabricating mid-infrared lasers on microelectronics-compatible silicon can greatly reduce their cost because they can be made using the same high-volume processing techniques used to make the silicon microelectronics that power cell phones and computers.”

The new fabrication approach is described in Optica, The Optical Society’s (OSA) journal for high impact research. The work was conducted at the EXTRA facilities and as part of the REDFINCH consortium, which is developing miniaturized, portable low-cost optical sensors for chemical detection in both gases and liquids.

Je participe prochainement, les 23 & 24 novembre 2019, à Substrates, marché d'artistes à Lanester (56) organisé par Atelier Scarole & Scotus.

D’un premier sang galvanisant à cette deuxième édition certifiée prometteuse, c’est un Substrates et sa trentaine d’invités qui prennent place, cette fois, dans la totalité des docks de Quai 9.

Le papier imprimé avant tout, la petite édition comme fer de lance : la sérigraphie, la linogravure, le cyanotype, les fanzines, la photocopie, bien sûr. Mais aussi la musique autodiffusée, la cassette avec sa jaquette risographiée, le flash tatoué sur place...

Substrates met en avant tout cela, fait la part belle au dessin, à l’image, au graphisme et est ouvert à tous, petits et grands, néophytes et connaisseurs.

which sounds like bullshit

Oh fun, I think I've noticed one or two of these too; but yes a bunch of others immediately look like stretches, say, *ter- seems to mean primarily 'weak', only secondarily from there 'young creature', and specific 'child' only in a few still more derived reflexes like in Ossetic and Albanian.

Oh I dunno, it's not the sort of a thing you usually have favorites in. There's a couple very different ways to even read this. Favorite substrate language? Favorite language-that-has-a-substrate? Favorite corpus of substrate vocabulary…?

Exploring the 'dark side' of a single-crystal complex oxide thin film

Analysis from a team led by Argonne researchers reveals never-before-seen details about a type of thin film being explored for advanced microelectronics.

Research from a team led by scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory offers a new, nanoscopic view of complex oxides, which are  promising for advanced microelectronics.

Complex oxides are multifunctional materials that could eventually lead to energy-efficient, advanced electronic memory components and quantum computing devices. Generally, these materials are produced layer-by-layer on an atomically matched substrate, a process known as epitaxial growth.

To use complex oxides in electronics, they need to be produced on silicon—an impossible task for existing epitaxial growth techniques, since the atomic structures of these two materials do not match. One possible workaround is to grow the complex oxides elsewhere and then transfer the film to another substrate. However, a key question arises: Will the local properties of a complex oxide thin film remain intact if you lift it from one substrate and deposit it on another?

Borophene has a nearly perfect partner in a form of silver that could help the trendy two-dimensional material grow to unheard-of lengths.

A well-ordered lattice of silver atoms makes it possible to speed the growth of pristine borophene, the atom-thick allotrope of boron that so far can only form via synthesis by molecular-beam epitaxy (MBE).

By using a silver substrate and through careful manipulation of temperature and deposition rate, scientists have discovered they can grow elongated hexagon-shaped flakes of borophene. They suggested the use of a proper metal substrate could facilitate the growth of ultrathin, narrow borophene ribbons.

New work published in Science Advances by researchers at Rice and Northwestern universities, Nanjing University of Aeronautics and Astronautics and Argonne National Laboratory will help streamline the manufacture of the conductive material, which shows potential for use in wearable and transparent electronics, plasmonic sensors and energy storage.

That potential has fueled efforts to make it easier to grow, led by Rice materials scientist Boris Yakobson, a theorist who predicted that borophene could be synthesized. He and collaborators Mark Hersam at Northwestern and lead author Zhuhua Zhang, a Rice alumnus and now a professor at Nanjing, have now demonstrated through theory and experimentation that large-scale, high-quality samples of borophene are not only possible but also allow qualitative understanding of their growth patterns.
