The institutional paradox of a substantivist conception of the economy in public policy: Insights from public procurement for solidarity economy in Ecuador

Annals of Public and Cooperative Economics, Volume 97, Issue 3, Page 871-900, September 2026.
Abstract Ecuador's 2008 Constitution advanced an ambitious substantive economic vision through Buen Vivir (Good Living), recognizing a plural economy which encompasses private, public and solidarity economy (SE) sectors. This paper aims to analyze public procurement programs in Ecuador, one of the flagship Buen Vivir policies for SE promotion.

3D‐Nanoprinted Fluidically Steerable Soft Robotic Microcatheters

Advanced Robotics Research, Volume 2, Issue 4, August 2026.
This work introduces a ∼3‐French (1 mm‐in‐diameter) soft robotic microcatheter fabricated by means of two‐photon direct laser writing. The 3D‐printed microcatheter enables remote, on‐demand steering via microfluidic actuation for guidewire‐free navigation of vascular networks as well as microcatheter‐mediated delivery of fluidic payloads to target ...

Shear‐Induced Emergence of Aromatic Superlow‐Friction Interfaces in Amorphous Carbon: Triggering Chemical Impurities and Atomic‐Scale Mechanisms

Advanced Science, Volume 13, Issue 43, 3 August 2026.
High‐throughput quantum‐mechanical simulations reveal that amorphous carbon undergoes shear‐driven structural transformation into aromatic, graphene‐like interfaces. This mechanochemical process is governed by dopant chemistry: dopants with valency less than four promote the emergence of superlow‐friction amorphous graphene, whereas tetra‐valent ...
