The ripples of the Industrial revolution: exports, economic growth and regional integration in Italy in the early 19th century [PDF]
The conventional wisdom about the early stages of modern economic growth in Italy is still heavily influenced by the work of L.Cafagna (1989). He argued that exports of primary products to industrializing North Western countries were the main source of ...

Ti3C2Tx MXene and Ag nanoparticles are embedded into piezoelectric nanofibers to form a stretchable, self‐powered coil that converts mechanical deformation into electrical energy. The device enables controllable power output during stretching and release while maintaining a compact and lightweight architecture, making it suitable for miniaturized ...

This work reveals a “Photovoltaic‐Capacitance” coupling mechanism in stacked Ga2O3/ZnO devices, defining the ZnO/graphene interface as a novel Photovoltaic Dynamic‐Capacitor (PDC). The wavelength‐selective bipolar response enables a physical layer secure communication protocol based on ternary optical logic (“1,” “0,” “−1”).

Programmable crack dynamics engineering enables flexible strain sensors with high linearity
First‐decoupling theoretical framework of crack evolution elucidating the control methods, mechanistic insights, and structure‐activity relationships is established. Crack propagation from uncontrollable randomness systematically evolves into spatially ordered states.

ABSTRACT Field visits are common phenomena with non‐governmental organisations in Uganda. During these visits, Ugandan national staff guide visitors on series of meetings and interactions in the field. Following an actor‐oriented approach and drawing on ethnographic data on 14 field visits, this paper understands the field visit as a microcosm for the ...
