Study on Impurity Particle Detection in Transformer Oil Based on Microflow Imaging Method

open access: yesHigh Voltage, EarlyView.
ABSTRACT The concentration of particles in transformer oil has a significant influence on its electrical performance, making oil cleanliness a critical parameter in the operation and maintenance of power transformers. However, the light obstruction (LO) method recommended by current standards has inherent limitations, including low sensitivity to ...

Investigation into the delivery and evaluation of a unique Avena sativa (Oat) Lipid Extract on skin barrier using LC‒MS/MS, Raman spectroscopy, immunostaining analysis and skin efficacy

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Abstract Objectives Oat lipids are rich in ceramides. In this investigation, we analysed the delivery of a specific Oat Lipid Extract derived from Avena sativa, comprising ‘skin identical’ ratios of fatty acids, ceramides and cholesterol/sterol. This investigation is the first reported investigation of oat lipids utilizing Raman spectroscopy for the ...

Mixed‐Functionalized Acylgermanes Result in Wavelength‐Controlled Fragmentation

open access: yesAngewandte Chemie, Volume 138, Issue 20, 11 May 2026.
Selective radical generation from PEG‐acylgermanes is achieved by controlling the used wavelength. Distinct aryl‐carbonyl units undergo wavelength‐dependent α‐cleavage, producing radicals with different reactivities. UV/Vis, TD‐DFT, and photo‐CIDNP spectroscopy confirm that small adjustments in light input directly dictate radical identity and ...

Parallel Optical Random Access Memory (PORAM) [PDF]

open access: yes
It is shown that the need to minimize component count, power and size, and to maximize packing density require a parallel optical random access memory to be designed in a two-level hierarchy: a modular level and an interconnect level.

Hyperspectral tomographic diffractive microscopy: Development and applications

open access: yesJournal of Microscopy, EarlyView.
Abstract Tomographic Diffractive Microscopy (TDM) provides label‐free three‐dimensional imaging of transparent samples with resolution surpassing confocal limits. At IRIMAS, successive instrumental developments since 2009 have enhanced TDM capabilities through transmission, reflection, isotropic, polarisation‐sensitive, and dual‐view configurations ...

The Painterly Materiality of Clouds in Antony and Cleopatra and Hamlet

open access: yesRenaissance Studies, EarlyView.
Abstract This article examines the cloud‐gazing scenes in Antony and Cleopatra and Hamlet through the lens of early modern artistic theory and material practices, particularly the art of limning. Building upon existing philosophical and poetic interpretations of Shakespearean clouds as metaphors for ephemerality and memory, the essay argues that the ...

Exploring the Relationship Between a PST's Written Noticings of Student Mathematical Reasoning and Their Reported and Actual Viewing of a 360 Video

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT An essential aspect of mathematics teacher education is the development of professional noticing. A 360 video is a new technology that can aid in developing mathematical teacher noticing. This study examines the relationship between preservice teachers' noticing of mathematical student thinking and the variation in their physical focusing ...
