Are Planetary Systems Filled to Capacity? A Study Based on Kepler Results
, 2013 We used a sample of Kepler candidate planets with orbital periods less than 200 days and radii between 1.5 and 30 Earth radii to determine the typical dynamical spacing of neighboring planets.

Planet gaps in the dust layer of 3D proto-planetary disks: Observability with ALMA [PDF]
, 2013 Among the numerous known extrasolar planets, only a handful have been imaged directly so far, at large orbital radii and in rather evolved systems. The Atacama Large Millimeter/submillimeter Array (ALMA) will have the capacity to observe these wide ...

Advanced Functional Materials, EarlyView.A wideband tunable electrochromic device with dynamic thermal emissivity control is demonstrated. The system enables adaptive heat regulation via electrochemically modulated silver deposition, achieving efficient cooling and heating states. The flexible design ensures mechanical robustness under bending conditions, making it promising for portable and ...

Titius-Bode’s Relation and Distribution of Exoplanets [PDF]
Journal of Astronomy and Space Sciences, 2010 The distance distribution in our planetary system has been a controversial matter. Two kinds of important issues on Titius-Bode’s relation have been discussed up to now: one is if there is a simple mathematical relation between distances of natural ...

Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow
Advanced Functional Materials, EarlyView.Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.

Dead Zones as Thermal Barriers to Rapid Planetary Migration in Protoplanetary Disks
, 2010 Planetary migration in standard models of gaseous protoplanetary disks is known to be very rapid ($\sim 10^5$ years) jeopardizing the existence of planetary systems.

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.

Cryptic geological histories accessed through entombed and matrix geochronometers in dykes
Communications Earth & EnvironmentDeep geology of ancient continental crust can be difficult to access, with direct observation restricted to limited exposures. The age and composition of hidden geology can be gleaned from indirect isotopic modelling or via detrital minerals within ...

Problem of planetary systems existence. II. Expected properties and the first results of the search
Вісник Астрономічної школи, 2004 Specialities of planets composition, their physical properties and classification are discussed. For planetary systems of different ages analysis of coming configurations is carried out. It is shown, that there are two principal vicinities on the diagram
