Robust low-distortion wideband CMOS current-follower

Electronics Letters, 1999
A wideband CMOS low-distortion current-follower is proposed. The circuit is suitable for low-voltage, high-frequency and low distortion VLSI applications. The design avoids the use of current mirror(s) in the signal path in order to minimise the distortion caused by mismatched mirroring transistors.

Hands‐on protocol for preparing water‐soluble fractions from agri‐food samples for NMR‐based metabolomics analysis

FEBS Open Bio, EarlyView.
This research protocol outlines a workflow for nuclear magnetic resonance (NMR)‐based metabolomics in the agri‐food sector. Using two case studies—strawberry leaves (solid matrix) and wine (liquid matrix)—it details the procedures for sample preparation, data acquisition, and processing.

Non-saturating magnetoresistance of inhomogeneous conductors: comparison of experiment and simulation [PDF]

, 2007
The silver chalcogenides provide a striking example of the benefits of imperfection. Nanothreads of excess silver cause distortions in the current flow that yield a linear and non-saturating transverse magnetoresistance (MR).

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

FEBS 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 ...

Behavior of current transformers under distorted waveforms

2015 IEEE PES Innovative Smart Grid Technologies Latin America (ISGT LATAM), 2015
The use of nonlinear loads connected to the power networks that produce distorted currents has been increased in the last years. At the same time, distributed generation has also been increased. It uses power electronic devices to inject the energy to the network, generating harmonic currents that flow though the networks.

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

FEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.
