Radio loud AGN and the L_X - \sigma relation of galaxy groups and clusters

, 2008
We use the ROSAT All-Sky Survey to study the X-ray properties of a sample of 625 groups and clusters of galaxies selected from the Sloan Digital Sky Survey.

Narrowband Detection via Charge Collection Narrowing Organic Photodetector Enabled by Low Bandgap Random Terpolymer for Biometric Sensing

Advanced Functional Materials, EarlyView.
A novel low‐bandgap random terpolymer is designed for narrow band detection in charge collection narrowing (CCN) based organic photodetectors. With a relative thin active layer (<1 µm), the CCN‐based devices achieved a narrowband response of 68 nm full‐width‐at‐half‐maximum at 916 nm, together with Responsivity values of 0.13 A W−1 and dark current of ...

All‐Cellulose‐Based Photonic Glitters

Advanced Functional Materials, EarlyView.
Uniform, disc‐shaped photonic CNC glitters with adjustable structural colors and diameters are fabricated on hydrophilic ethyl cellulose films using electrospray deposition. By employing patterned ethyl cellulose films with pre‐designed hydrophilic regions, photonic patterns can be created with these all‐cellulose‐based glitters, demonstrating their ...

Self‐organized Criticality in Neuromorphic Nanowire Networks With Tunable and Local Dynamics

Advanced Functional Materials, EarlyView.
Memristive nanowire networks (NWNs) are shown to be electrically tunable to a critical state where specific local dynamics evaluated by multiterminal characterization are exploited as feature selection in nonlinear transformation (NLT) tasks.

RADIO'S ADAPTABILITY IN THE DIGITAL ERA

, 2021
The digital revolution has had a dramatic impact on all areas of activity and radio has been forced to comply with the rigors imposed by the new media paradigm. Its proven capacity to adapt to the ever-changing journalistic landscape, deeply influenced by the Internet and the expansion of social media, provided the means for radio to reinvent itself ...

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

Advanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.
