Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

A High Step-up Integrated Coupled Inductor-Capacitor DC-DC Converter

open access: yesIEEE Access, 2021
A high step-up integrated coupled inductor-capacitor DC-DC converter for renewable energy applications has been proposed in this paper. Because of relative low output voltage of renewable energy systems, a high step-up converter is necessary.

Dapagliflozin prevents methylglyoxal‐induced retinal cell death in ARPE‐19 cells

open access: yesFEBS Open Bio, EarlyView.
Diabetic macular oedema is a diabetes complication of the eye, which may lead to permanent blindness. ARPE‐19 are human retinal cells used to study retinal diseases and potential therapeutics. Methylglyoxal is a compound increased in uncontrolled diabetes due to elevated blood glucose.

Approach to the modelling of capacitor-less linear-assisted DC-DC regulators as candidate topology for battery chargers [PDF]

open access: yes, 2017
Two different alternatives have been widely used for decades to provide the necessary power supply energy to charge battery systems. These two alternatives are known largely: (1) The use of voltage series linear regulators (classic standard NPN –or nMOS–

Islanding detection in three-phase and single-phase systems using pulsating high-frequency signal injection [PDF]

open access: yes, 2015
This paper analyzes the use of pulsating high-frequency signal injection for islanding detection purposes. Active islanding detection using high-frequency signal injection is an appealing option due to its reduced nondetection zone, reduced cost, and ...

Unlocking the Power of Quercetin‐Encapsulated Mesoporous Bioactive Glass Nanoparticles: A Multifunctional Approach to Bone Regeneration

open access: yesAdvanced Engineering Materials, EarlyView.
Mesoporous bioactive glass nanoparticles (MBGNs) are investigated for bone regeneration given their remarkable structural and functional properties. MBGNs are functionalized with Mn and Cu and incorporated with quercetin, a natural flavonoid exhibiting antioxidant, anti‐inflammatory, and antimicrobial properties.

Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects

open access: yesAdvanced Engineering Materials, EarlyView.
Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...
