Modifying Electronic and Elastic Properties of 2-Dimensional [110] Diamond by Nitrogen Substitution

open access: yesC, 2021
One type of two-dimensional diamonds that are derived from [111] direction, so-called diamane, has been previously shown to be stabilized by N-substitution, where the passivation of dangling bonds is no longer needed.

An Improved Analysis Method for Organic Rankine Cycles Based on Radial-Inflow Turbine Efficiency Prediction

open access: yesApplied Sciences, 2018
The organic Rankine cycle (ORC) has been demonstrated to be an effective method for converting low-grade heat energy into electricity. This paper proposes an improved analysis method for the ORC system.

The *-Prikry condition [PDF]

open access: yesReports on Mathematical Logic, 2018
In this paper we isolate a property for forcing notions, the *-Prikry condition, that is similar to the Prikry condition but that is topological: A forcing P satisfies it iff for every p ∈ P and for every open dense D ⊆ P, there are n ∈ ω and q ≤∗ p such that for any r ≤ q with l(r) = l(q) + n, r ∈ D, for some length notion l.

OBJECT-ORIENTED CHANGE DETECTION BASED ON SPATIOTEMPORAL RELATIONSHIP IN MULTITEMPORAL REMOTE-SENSING IMAGES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
In this paper a novel object-oriented change detection approach in multitemporal remote-sensing images is proposed. In order to improve post classification comparison (PCC) performance, we propose to exploit spatiotemporal relationship between two images

Numerical simulation study of novel air-cooled condenser with lateral air supply

open access: yesCase Studies in Thermal Engineering, 2019
Uneven distribution of internal temperature and air flow field are considered to be the essential defects of the Λ-frame air-cooled condenser (ΛACC) in a power plant.

Hexagonal B–C–N composite consisting of h-BN and graphite separated by B–C nanolayer [PDF]

open access: yesMatter and Radiation at Extremes
Graphite and hexagonal boron nitride (h-BN), despite their structural similarity, exhibit opposing electronic properties, namely, metallic conductivity and wide-bandgap insulation, respectively.
