Trap‐Assisted Transport and Neuromorphic Plasticity in Lead‐Free 2D Perovskites PEA2SnI4

open access: yesAdvanced Functional Materials, EarlyView.
An artificial retina built from lead‐free layered perovskite (PEA)2SnI4 converts light input into a persistent photocurrent and sums successive flashes over time. Micro/nanocrystals integrated on electrodes act as synapse‐like pixels that perform temporal integration directly in hardware. This in‐sensor preprocessing merges detection and computation on

From Mechanics to Electronics: Influence of ALD Interlayers on the Multiaxial Electro‐Mechanical Behavior of Metal–Oxide Bilayers

open access: yesAdvanced Functional Materials, EarlyView.
Ultrathin AlOxHy interlayers between aluminum films and polymer substrates significantly improve electro‐mechanical properties of flexible thin film systems. By precisely controlling interlayer thickness using atomic layer deposition, this study identifies an optimal interlayer thickness of 5–10 nm that enhances ductility and delays cracking.

Exciton‐Polaritons in Nanoscale Metal‐Organic Frameworks: A Platform for the Reversible Modulation of Strong Light‐Matter Coupling via the Chemical Environment

open access: yesAdvanced Functional Materials, EarlyView.
Strong exciton‐photon coupling is achieved by integrating porphyrin ligand‐based MOF nanoparticles in optical cavities, as evidenced by pronounced polariton branch anticrossing. The porous nature of the resonator enables precise, reversible tuning via vapor pressure, unlocking unprecedented chemical‐environment controlled dynamic polaritonic platforms ...

Problems of silver import to India, connected with the world economic crisis

open access: yesRUDN Journal of Engineering Research, 2010
In India 76% of silver simultaneously is extracted from lead-zinc and from small quantity of Gold deposits. About 30% of consuming silver is produced in country. India occupied the third place of silver consuming in 2007 year.

Mapping Nanoscale Buckling in Atomically Thin Cr2Ge2Te6

open access: yesAdvanced Functional Materials, EarlyView.
Atomic‐resolution STEM is used to resolve nanoscale buckling in monolayer Cr2Ge2Te₆. A noise‐robust image analysis reconstructs three‐dimensional lattice distortions from single plan‐view images, revealing pronounced defect‐driven nm‐scale out‐of‐plane buckling.

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

open access: yesAdvanced Functional Materials, EarlyView.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Nanolayer‐Encapsulated Stretchable Liquid‐Metal Sheets for Thermal Management

open access: yesAdvanced Functional Materials, EarlyView.
A stretchable liquid metal sheet with both high thermal conductivity and mechanical flexibility is developed. Its trilayer structure, comprising copper‐particle‐dispersed gallium liquid metal encapsulated by styrene‐butadiene‐styrene nanosheets, shows 40.4 W m−1 K−1 conductivity, elongation exceeding 200%, and retention of 96% of its initial ...

Brännspegeln som myt och objekt

open access: yesLychnos, 2019
The Army Museum’s collections include a unique burning mirror. There is no equivalent in any other museum collection in the world. It was long claimed that the mirror came to Sweden as a war trophy from Prague in 1648.

Anomalous reflection coefficient underlying experimentally validated outstanding transmission through metal–dielectric–metal microcavities

open access: yesJournal of the European Optical Society-Rapid Publications
Analytical modelling of light transmission through a metal-insulator-metal geometry embedded in a coupling glass surrounding medium is possible through an extended Fabry-Pérot formula.
