Tunable 3D Aerosol Jet Printing of Low‐Power Redox‐Gated Transistors with Multicomponent Inks

open access: yesAdvanced Materials Technologies, EarlyView.
Printed hybrid electronics emerge as a versatile option for fabricating microelectronics using customized multicomponent inks. Leveraging additive manufacturing, redox‐chemistry, and correlated metal oxide nanoparticles, this study presents a multilayered solid‐state VO2 transistor fabricated via aerosol jet printing.

Transit surveys for Earths in the habitable zones of white dwarfs

open access: yes, 2011
To date the search for habitable Earth-like planets has primarily focused on nuclear burning stars. I propose that this search should be expanded to cool white dwarf stars that have expended their nuclear fuel. I define the continuously habitable zone of

Surfing the Color Map with Carbazole‐Appended Cyclometalated N‐Heterocyclic Carbene Pt Complexes and Their Application in Green Organic Light‐Emitting Devices

open access: yesAdvanced Optical Materials, EarlyView.
Complexes [PtII(Cbz‐C^C*bzim/im)(L^L)], bearing carbazole‐appended cyclometalated NHCs, show bright phosphorescence, peaking from the blue to the yellowish–green spectral range depending on the carbene, L^L, and doping concentration. Non‐doped OLEDs using 1A or 3A (L^L = acac or P^O2) reach the best performances (Von: 2.99 V, 2.55 V; Lmax: 39208, 25837

Toward Enhancing Chiro‐Optical and Magneto‐Optical Properties of Magnetic Nanocrystals by Surface Plasmons

open access: yesAdvanced Optical Materials, EarlyView.
Here, recent progress is highlighted in colloidal magnetoplasmonic hybrid nanomaterials, with a focus on chiral plasmonics. Metal nanocrystals with intrinsic chiroptical features can lead to a combination of chiral plasmonics and magneto‐optics effects when interacting with the magnetic counterpart, offering a foundation for systematically designing ...

Some new methods for planetary exploration [PDF]

open access: yes, 1965
For many centuries the planets of our solar system have been objects of study by astronomers. Before the invention of the telescope, these studies were restricted to an attempt to understand and predict their motion.

A grid of polarization models for Rayleigh scattering planetary atmospheres

open access: yes, 2009
We investigate the intensity and polarization of reflected light from planetary atmospheres. We present a large grid of Monte Carlo simulations for planets with Rayleigh scattering atmospheres. We discuss the disk-integrated polarization for phase angles

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.

open access: yesAdvanced Photonics Research, EarlyView.
Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%

open access: yesAdvanced Robotics Research, EarlyView.
Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...
