Metachromatic Butterfly Bile Pigments for Multi‐Level Optical Security Films
Bio‐derived optical security materials are manufactured by embedding butterfly‐based pigments in polymer films. Tunable color and fluorescence responses arise from concentration‐controlled metachromasy, enabling spatially encoded patterns with distinct visible, UV‐active, and spectral signatures.

Ultrasmall Platinum Nanoparticles for Radiation‐Enhanced Cancer Therapy
This work proposes a nanomedicine‐based strategy to enhance X‐ray radiotherapy for cancer treatment. Ultrasmall Pt‐NPs exhibit catalase‐like activity that may contribute to modulation of the tumor microenvironment and amplify interactions between radiation and biological matter, leading to increased DNA damage.

INDUSTRIAL DISTRICTS AS LOCAL SYSTEMS OF INNOVATION [PDF]
This essay examines the situation and the lines of development of industrial districts from the point of view of local systems of innovation. First of all, this article points out to the modernity factors of the district model – which are ascribable to ...

Balancing Electrons to Break the Activity‐Selectivity Trade‐Off in H2O2 Electrosynthesis
Carrier‐concentration balancing in CuS is achieved by coupling cobalt dopants with cobalt vacancies, converting CuS from p‐ to n‐type to accelerate 2e− ORR while withdrawing excess carriers to optimize *OOH binding for H2O2 desorption. The catalyst reaches 8.14 mol g−1 h−1 with >84% selectivity in 1.0 M KOH and drives robust electro‐Fenton dye ...

Industrial districts in a globalizing world: A model to change or a model of change? [PDF]
Industrial districts – and especially industrial districts in Italy – have been put forth as a model of economic development premised on the deep rooting of firms in a local socio-economic system that is both rich in skills and tied into international ...

Electrochemical CO2 reduction (ECR) to formate is a promising route for sustainable chemical production. Herein, we report the synthesis catalysed byBi‐HfO2@C. The AIMD simulations, DFT calculations, and in situ SEIRAS measurements show that the modification of HfO2 on the Bi surface steers the interfacial water to adopt a favorable hydrogen‐down (OH2↓)

A 2D heterointerface with a two‐site anchor bridge suppresses nonradiative recombination at the perovskite/C₆₀ interface by reducing surface defects, elevating the Fermi level, and strengthening the electric field. This strategy enables efficient electron extraction, delivering 26.32% efficiency, 1.217 V Voc, excellent operational stability, and broad ...

Electoral accountability, fiscal decentralization and service delivery in Indonesia [PDF]
This paper takes advantage of the exogenous phasing of direct elections in districts and applies the double difference estimator to: (i) measure impacts on the pattern of public spending and revenue generation at the district level; and (ii) investigate ...
