Physico‐Chemical Understanding of Plasticizers Interaction with P(VDF‐TrFE‐CFE) Electroactive Polymer

Macromolecular Materials and Engineering, EarlyView.
This study explores the effects of DNOP plasticizer on P(VDF‐TrFE‐CFE) terpolymers, revealing a strong synergy between chemical structure and physical properties. High TrFE bringing natural flexibility and CFE enhancing the plasticizer retention through theorized halogen bonds, ultra‐soft, crack‐free films of high permittivity and softness are ...

A New 6–15 GHz Solar Radio Observation System

The Astrophysical Journal Supplement Series, 2023
In this study, we have developed a centimeter-band solar radio telescope covering the 6–15 GHz frequency band. The radio telescope has the outstanding advantages of a large instantaneous sampling bandwidth and wide frequency coverage.

Voice and Speech in Atypical Parkinsonian Disorders

Movement Disorders Clinical Practice, EarlyView.
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.

Investigation of the laser fluence and wavelength dependence in surface‐assisted laser desorption/ionization mass spectrometry using gold nanoparticles

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Surface‐assisted laser desorption/ionization (SALDI) mass spectrometry (MS) builds on the use of nanostructured surfaces (e.g., coatings of colloidal nanoparticles) to promote analyte desorption and ionization. The SALDI process is believed to occur mainly through thermal processes, resulting from heating of the nanosubstrate upon absorption ...

CLASS B0827+525: `Dark lens' or binary radio-loud quasar? [PDF]

, 2000
We present radio, optical, near-infrared and spectroscopic observations of the source B0827+525. We consider this source as the best candidate from the Cosmic Lens All-Sky Survey (CLASS) for a `dark lens' system or binary radio-loud quasar.

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Mechanochemical Synthesis of X‐Vinylbenziodoxol(on)es and One‐Pot Conversion to Complex Alkenes**

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
The synthesis of a wide range of complex 1,2‐di(heteroatom)‐substituted (Z)‐alkenes is achieved through a mechanochemical one‐pot reaction of ethynylbenziodoxol(on)es (EBX/EBO) with a variety of heteroatom nucleophiles. The mechanochemical activation enables synthesis of a range of novel vinylbenziodoxol(on)es (VBX/VBO) whose synthesis is inefficient ...
