A Printed Zinc‐Ion Microbattery with Extended Shelf Life and Durability for Energy Autonomous Sensors

open access: yesAdvanced Functional Materials, EarlyView.
We present a fully printed aqueous zinc‐ion microbattery (ZnIB) enabled by graphene‐decorated zinc anode and printed MnO@NC cathode using sustainable aqueous‐based ink formulations. The printed 3D electrodes ensure uniform zinc deposition, low overpotential, and long‐term stability.

DNA‐Origami‐Assembled Rhodium Nanoantennas for Deep‐UV Label‐Free Single‐Protein Detection

open access: yesAdvanced Functional Materials, EarlyView.
Deep‐UV autofluorescence of single proteins in DNA origami‐based rhodium nanoantennas. Precisely positioned within the plasmonic nanogap, proteins retain their native state while their intrinsic emission is strongly amplified, enabling label‐free single‐molecule detection and opening new opportunities for highly sensitive and specific biosensing ...

After 410

open access: yesActa ad archaeologiam et artium historiam pertinentia, 2004
This essay attempts to disqualify the date of 410, when Alaric sacked Rome, as a significant event in the history of art. It forms part of a much longer investigation of periodicity and its boundaries, especially with the respect to the nature of Late Antique art, ambivalently at the end of an artistic tradition and at the beginning of another.

Nutrition and growth in Italy, 1861-1911 what macroeconomic data hide [PDF]

open access: yes, 2004
We investigate how nutritional status responded to economic growth in Italy during 1861-1911. By combining household-level data on food consumption with population censuses, we estimate that the incidence of undernutrition decreased by about 10-15 ...

Establishing a Model Precursor System: Over a Decade of Research on Carbon Dots from the Citric Acid‐Urea System

open access: yesAdvanced Functional Materials, EarlyView.
The citric acid/urea (CA‐Urea) precursor system offers a versatile, scalable route to carbon dots with tunable luminescence and multifunctionality. Mechanistic insights into precursor chemistry and reaction parameters have enabled doping, surface modification, and hybridization strategies, yielding CDs for luminescent devices, sensing, catalysis ...
