Bureaucratic limits of firm size: Academic summary [PDF]

open access: yes
The research tests Oliver Williamson’s proposition that transaction cost economics can explain the limits of firm size. Williamson suggests that diseconomies of scale are manifested through four interrelated factors: atmospheric consequences due to ...

Fabrication of Pyridinic Nitrogen‐Functionalized Carbon Cloth for High‐Performance Iron‐Chromium Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The carbon cloth electrode with targeted pyridinic nitrogen doping, achieved via urea pyrolysis, effectively modulates the adsorption of Cr(II) species and enhances electron transfer, leading to significantly improved kinetics of the Cr(II)/Cr(III) reaction. The material demonstrates a high discharge capacity of 689.3 mAh and an energy efficiency of 72.

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control

open access: yesAdvanced Functional Materials, EarlyView.
A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...

Weak Scale Effects in Growth Models [PDF]

open access: yes
Growth models of the second generation type, e.g. the Jones (1995) or Young (1998) model, all exhibit a so called weak scale effect in per capita production, i.e. larger economies should have a higher per capita production than smaller economies. However,

Dispensing Volumetric Additive Manufacturing

open access: yesAdvanced Functional Materials, EarlyView.
Dispensing volumetric additive manufacturing (DVAM) prints 3D structures inside a photocurable resin droplet suspended from the tip of a glass pipette, enabling sequential printing without resin vats or manual part removal. Real‐time droplet profiling and ray‐tracing‐based correction compensate for optical distortion at the curved resin‐air interface ...

Rise And Fall Of Cities, Measuring Spatial Clustering And Economies Of Urban Agglomeration In West Java [PDF]

open access: yes
With others neighboring Provinces in the western part of Java, the West Java Province shares the southeast Asian most densely urban area (Bodebek as part of Jabodetabek and Greater Bandung). This research tries to identify the spatial clustering of urban
