Ultrafast Nonlinear Dynamics of Indium Tin Oxide Nanocrystals Probed via Fieldoscopy
Advanced Science, EarlyView.The ultrafast nonlinear dynamics of indium tin oxide nanocrystals excited with 1 MHz, 10 fs pulses, at their localized surface plasmon frequency, and near their epsilon‐near‐zero wavelength is probed via fieldoscopy. The study demonstrates fluence‐dependent switching behavior, advancing the understanding of high‐speed optical modulation in plasmonic ...

Advanced Science, EarlyView.A transfer‐free fabrication method enables multilayer graphene microelectrodes as small as 10 µm, eliminating reliability issues of manual graphene transfer. These electrodes record neural activity in brain slices with exceptional signal‐to‐noise ratios (up to 25–40 dB) while maintaining optical transparency for multimodal applications.

Electronically tunable bandpass filter
, 1990 An electronically tunable bandpass filter is presented. It is a combline filter realized in microstrip form. The filter is made tunable by using the variable capacitance of a GaAs fet (or of a varactor). With the use of this technique it is possible to achieve relative bandwidth from 8% to 30%, a tuning bandwidth 'up to 50% and a center frequency up to

Coupling coefficients of combline resonators [PDF]
, 2005 Bandpass filters require elements that behave as series or parallel resonant circuits. In this paper, we discuss a variety of couplings between combline resonators in bandpass filter applications.

Advanced Science, EarlyView.A femtosecond UV pump–probe microscope resolves binding‐induced changes in protein excited‐state dynamics and converts these intrinsic contrasts into an equilibrium affinity readout. By probing tryptophan responses directly in solution, the approach enables quantitative determination of dissociation constants without labeling or immobilization ...

Deformation Driven Suction Cups: A Mechanics‐Based Approach to Wearable Electronics
Advanced Science, EarlyView.Deformation‐driven suction cups enable robust, reversible adhesion of wearable electronics to human skin spanning wide mechanical compliance, without adhesives or tight straps. By integrating mechanics modeling, experiments, and contact mechanics theory, this work reveals how cup geometry, substrate compliance, and interfacial adhesion govern suction ...
