Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

open access: yesAdvanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

First results of absolute measurements of solar flux at the Irkutsk Incoherent Scatter Radar (IISR)

open access: yesSolar-Terrestrial Physics, 2018
The Irkutsk Incoherent Scatter Radar (IISR) allows us to carry out passive radio observations of the Sun and other powerful radio sources. We describe a method for absolute measurements of spectral flux density of solar radiation at IISR.

Multimodal Soft Surgical Robots Enabled by Eco‐Degradable, Sterilizable Polymers and Transient Electronics

open access: yesAdvanced Functional Materials, EarlyView.
A compostable PGS soft surgical robot with interchangeable modules integrates transient Mo tactile and Si thermal sensors for dual feedback. The device preserves its function after clinical‐grade sterilization, demonstrates stable actuation and cardiac tissue grasping with real‐time in vivo pulsatile monitoring, and biodegrades post‐use with soil‐safe,

ADVANCEMENTS IN SOLAR NEUTRINO PHYSICS [PDF]

open access: yesInternational Journal of Modern Physics E, 2013
We review the results of solar neutrino physics, with particular attention to the data obtained and the analyses performed in the last decades, which were determinant to solve the solar neutrino problem (SNP), proving that neutrinos are massive and oscillating particles and contributing to refine the solar models.

INTERACTION BETWEEN LONG-PERIOD ULF WAVES AND CHARGED PARTICLES IN THE MAGNETOSPHERE: THEORY AND OBSERVATIONS (OVERVIEW)

open access: yesSolar-Terrestrial Physics, 2021
The paper reviews the current state of the problem of interaction between long-period ultra-low-frequency (ULF) waves and high-energy particles. We consider elements of the theory of energy exchange between waves and particles, particle transport across ...

Interfacial Modulation for High‐Efficiency Large‐Area Organic Photovoltaics and Perovskite‐Organic Tandem Solar Modules

open access: yesAdvanced Functional Materials, EarlyView.
Self‐assembled monolayers (SAMs) are promising hole‐transporting materials for organic photovoltaics (OPVs), but suffer from self‐aggregation and poor large‐area uniformity. We find that interfacial modification using nicotinic hydrazide can eliminate the residual SAM aggregates by forming energetically favorable complexes, yielding uniform SAM.

The Role of Ultra‐Thin Buffer Layers for Achieving Ultra‐Low Dark Currents in Single‐Component Organic Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
Here, SubNc single‐component organic photodiodes (SC‐OPDs) are investigated, which achieve highly competitive performance metrics, including high EQE, ultra‐low JD, and high specific detectivity (D*). This study emphasizes the critical role of an organic buffer layer in studying the interface energetics and effects to achieve state‐of‐the‐art ...
