All-optical switches have attracted attention because they can potentially overcome the speed limitation of electric switches. However, ultrafast, energy-efficient all-optical switches have been challenging to realize due to the intrinsically small o

Graphene’s ultrafast carrier response enables ultrafast device operation, but its thinness makes graphene devices large and energy consuming. Introducing plasmonic nanostructures overcomes this problem and makes it possible to develop ultrafast, en

We have demonstrated ultracompact all-optical modulators by deep-subwavelength graphene-loaded plasmonic waveguides (60 × 40 nm2), and achieved an ultrafast response time (2.2 ps) with a substantially small consumption energy (155 fJ) for the first

Background and Aims: Although Helicobacter pylori is the most important bacterial carcinogen in gastric cancer (GC), GC can emerge even after H. pylori eradication. Studies suggest that various constituents of the gastric microbiome may influence GC

In this study, we propose a fabrication method to obtain composites of poly(vinyl alcohol) (PVA)/ionic cellulose nanofibers, in which a fiber structure is manipulated through a reconstruction of 2,2,6,6-tetramethyl-piperidinyl-1-oxyl radical (TEMPO)-

Plasma-induced frequency shift can be found in angularly resolved harmonic spectrographs by non-collinear high-harmonic generation. Based on the results we derive time-dependent ionization degree of the gaseous medium during high-harmonic conversion

Since the first successful isolation of Helicobacter pylori (H. pylori) from human gastric mucosa, this Organism has been demonstrated to be closely related to chronic, active gastritis and peptic ulcerations. It also promotes glandular atrophy of th
