Self‐Assembled Inorganic Nanomembrane Tubes: Rolled‐Up Piezoelectrics for Microacoustic Wave‐Based Actuators and Sensors

Advanced Materials, EarlyView.
This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

The provision of telecommunications links for the LEP collider [PDF]

Proceedings of the 1989 IEEE Particle Accelerator Conference, . 'Accelerator Science and Technology, 2003
The relatively large physical size of the CERN LEP (Large Electron-Positron) collider complex has resulted in a radically different approach to the provision of the telecommunications links for LEP compared with earlier accelerators. In previous accelerators, telecommunications links in the widest sense (links for voice, data, TV images, special ...

Giant Berry‐phase‐Driven X‐Ray Beam Translations in Strain‐Engineered Semiconductor Crystals

Advanced Materials, EarlyView.
Due to the Berry‐phase effect, X‐rays propagating in deformed crystals undergo large translations, interesting for X‐ray optics applications. Here, the lattice expansion observed upon H irradiation of dilute‐nitride semiconductors is exploited to engineer the deformation landscape of selectively hydrogenated GaAsN epilayers.

A Cu‐Based Near‐IR Active MOF with an Ion‐Pair Guest Exhibiting Versatile and Selective Gas‐Solid Reactivity

Advanced Materials, EarlyView.
The new Cu‐containing MOF (Me2NH2)(CuICl2)@[Cu4(INA)4Cl2O]·1.5dmf (3) contains a cation and an anion as guests and shows UV‐near‐mid‐IR absorption and near‐IR emission. MOF 3 shows gas‐solid reactivity in the presence of NH3 and HCOOH to yield two new 3D MOF.

Cascaded multiplexed optical link on a telecommunication network for frequency dissemination

Optics Express, 2010
We demonstrate a cascaded optical link for ultrastable frequency dissemination comprised of two compensated links of 150 km and a repeater station. Each link includes 114 km of Internet fiber simultaneously carrying data traffic through a dense wavelength division multiplexing technology, and passes through two routing centers of the telecommunication ...

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Synergistic Coupling of Host and Electrolyte Achieving 1270 Wh L−1 in Anode‐Free Lithium Metal Batteries

Advanced Materials, EarlyView.
A synergistic combination of a highly reversible host and a commercially viable carbonate‐rich electrolyte enables simultaneous stabilization of both anode and cathode interfaces in anode‐free lithium metal batteries. This integrated strategy delivers exceptional reversibility and a record volumetric energy density of 1270 Wh L−1 (including package) in
