Flexibility and Dynamicity Enhances and Controls Supramolecular Self‐Assembly of Zinc(II) Metallogels

open access: yesAdvanced Functional Materials, EarlyView.
Zinc(II) coordination complexes with tunable aryloxy‐imine ligands exhibit controllable supramolecular self‐assembly into hierarchical fibrous structures. Coordination‐driven stacking, not π–π interactions, enables gelation, dynamic assembly/disassembly, and enhanced nanomechanical properties.

Detection of a Temperature Inversion in the Broadband Infrared Emission Spectrum of TrES-4 [PDF]

open access: yes, 2008
We estimate the strength of the bandpass-integrated thermal emission from the extrasolar planet TrES-4 at 3.6, 4.5, 5.8, and 8.0 micron using the Infrared Array Camera (IRAC) on the Spitzer Space Telescope.

The Eclipse-Wind [PDF]

open access: yesNature, 1900
ALTHOUGH meteorological observations during total eclipses of the sun are of secondary importance, the changes of temperature and humidity being well known, yet it is still uncertain whether those changes do occur in atmospheric pressure, and, consequently, of wind, which, theoretically, ought to result from the sudden chilling of the air by the ...

Temperature perturbations in the troposphere-stratosphere over Thumba (8.5° N, 76.9° E) during the solar eclipse 2009/2010 [PDF]

open access: yesAnnales Geophysicae, 2011
Measurements of atmospheric temperature profiles in the troposphere and lower stratosphere were made over Thumba Equatorial Rocket Launching Station (TERLS) (8.5° N, 76.9° E) during a partial solar eclipse (22 July 2009) and an annular solar eclipse ...

FeDSNP‐Pa Nanoassemblies: A Triple‐Action Therapeutic Strategy Targeting Oxidative Stress, Inflammation, and Pyroptosis for Retinal Ganglion Cell Protection in Glaucoma

open access: yesAdvanced Functional Materials, EarlyView.
FeDSNP‐Pa, a metallized nanoparticle loaded with sodium pyruvate (Pa), exerts triple therapeutic effects by scavenging reactive oxygen species (ROS), suppressing inflammatory responses, and inhibiting pyroptosis signaling pathways. This multifunctional neuroprotective strategy protecting retinal ganglion cells (RGCs) from elevated intraocular pressure ...

On the ephemeris of the eclipsing polar HU Aquarii. II: New eclipse epochs obtained 2014 - 2018

open access: yes, 2018
The magnetic cataclysmic variable HU Aquarii displayed pronounced modulations of its eclipse timing. These were intensively modeled and discussed in recent years in the framework of planets orbiting the binary or the Applegate effect. No scenario yielded

The American Eclipse [PDF]

open access: yesNature, 1870
WILL you grant me space for a few words on my spectroscopic observations of the American eclipse, and what seem to me the inferences to be drawn from them? I make the request the more freely because I have met from time to time allusions to them in your journal, and remarks, some of which seem to require my notice, if only to express my appreciation of

The Eclipse of Reason - A Present Time Risk

open access: yesAcademicus International Scientific Journal
This paper contends that technical progress, from automation in industry to artificial intelligence, might involve the risk of a humanly impoverished society. Instrumental values could overcome final values and determine the end of meaning.
