Direct cross section measurement for the 18O(p,γ)19F reaction at astrophysical energies at LUNA

open access: yesEPJ Web of Conferences, 2017
18O(p, γ)19F plays an important role in the AGB star scenarios. The low energy cross section could be influenced by a hypothetical low energy resonance at 95 keV and by the tails of the higher energy broad states.

Sweeping a molecular Bose-Einstein condensate across a Feshbach resonance

open access: yes, 2004
We consider the dissociation of a molecular Bose-Einstein condensate during a magnetic-field sweep through a Feshbach resonance that starts on the molecular side of the resonance and ends on the atomic side.

Photoswitching Conduction in Framework Materials

open access: yesAdvanced Functional Materials, EarlyView.
This mini‐review summarizes recent advances in state‐of‐the‐art proton and electron conduction in framework materials that can be remotely and reversibly switched on and off by light. It discusses the various photoswitching conduction mechanisms and the strategies employed to enhance photoswitched conductivity.

Evaluation of optimum damping layout based on vibration energy analysis

open access: yesNihon Kikai Gakkai ronbunshu, 2014
We investigate vibration energy reduction method in harmonic vibration. A beam structure modeled by Finite Element approach is used as an example. Not only resonance condition but also non-resonance condition in which no particular mode is dominant, is ...

High Temperature Superfluid and Feshbach Resonance

open access: yes, 2003
We study an effective field theory describing cold fermionic atoms near a Feshbach resonance. The theory gives a unique description of the dynamics in the limit that the energy of the Feshbach resonance is tuned to be twice that of the Fermi surface.

Magnetic Control of Chiral Hybridized Phonon Magnetic Moments in Ferrimagnets Fe2‐xZnxMo3O8

open access: yesAdvanced Functional Materials, EarlyView.
Helicity‐resolved magneto‐Raman spectroscopy reveals magnetic control of chiral phonon magnetic moments in polar ferrimagnet (ZnxFe2−xMo3O₈). Large spontaneous zero‐field phonon splittings, selective phonon–magnon coupling, and asymmetric Zeeman responses demonstrate that phonon chirality is governed by magnon‐phonon coupling and magnetization.

A Λnn three-body resonance

open access: yesEPJ Web of Conferences, 2016
We solved the Faddeev equations in the Λnn system Jπ = ½+, T = 1). There is no bound state but found a resonance state. Complex Energy Method helps to find the location of the resonance energy in the complex Riemann sheet.

Engineering green fluorescent protein for improved brightness, longer wavelengths and fluorescence resonance energy transfer.

open access: yesCurrent Biology, 1996
BACKGROUND Variants of the green fluorescent protein (GFP) with different colors would be very useful for simultaneous comparisons of multiple protein fates, developmental lineages and gene expression levels.

Chemoselective Sequential Polymerization: An Approach Toward Mixed Plastic Waste Recycling

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by biological protein metabolism, this study demonstrates the closed‐loop recycling of mixed synthetic polymers via ring‐closing depolymerization followed by a chemoselective sequential polymerizations process. The approach recovers pure polymers from mixed feedstocks, even in multilayer formats, highlighting a promising strategy to overcome a
