Hierarchical Structure and Fabrication of Functionally Graded Biointerfaces in the Mussel Byssus
Advanced Materials Interfaces, EarlyView.The byssus is a fibrous protein‐based holdfast consisting of mechanically distinct interfaces, which mussels use to anchor their soft living tissue to hard seashore surfaces. Here, multiscale methodologies were used to elucidate the compositional and structural features underlying these functionally graded interfaces and how they are fabricated through

New Current-Mode Bandpass Filters Using Three Single-Output ICCIIs
Active and Passive Electronic Components, 2007 New current-mode bandpass filters using three single outputs inverting second generation current conveyors (ICCII) are introduced. The first circuit uses two ICCII+ and one ICCII−, and realizes an inverting bandpass response.

IEICE Electronics Express, 2007 In this paper, a super ultra-wideband (UWB) bandpass filter (BPF) with frequency bandwidth from 3.0GHz to 22.5GHz (-10dB-return loss bandwidth), which is much wider than that of the conventional UWB BPF, was proposed and demonstrated. The filter employed a simple and compact broadside-coupling structure.

Effective-fourth-order resonator based MASH bandpass sigma-delta modulators
, 1997 Two novel effective-fourth-order (eighth-order) resonator based MASH (MultistAge noise SHaping) bandpass Σ-Δ modulators are introduced at the behavioural level and subsequently examined by simulations utilising the ALTA SPW environment.

Advanced Materials Interfaces, EarlyView.This study establishes a dual‐channel optical metrology framework integrating phase‐shifting imaging ellipsometry and deep‐UV reflectance imaging. This label‐free approach enables simultaneous, time‐resolved mapping of film thickness and nanoparticle (NP) concentration in dynamic nanofluid thin films.
