A permeability model for the fractal tree-like fracture network with self-affine surface roughness in shale gas reservoirs

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
The complex natural fracture network with self-affine rough surface and branching characteristics significantly impacts the gas transport in shale gas reservoirs. However, its effects on the permeability have not been studied so far.

Long-term variability of the optical spectra of NGC 4151: I. Light curves and flux correlations

, 2008
Results of a long-term spectral monitoring of the active galactic nucleus of NGC 4151 are presented (11 years, from 1996 to 2006). High quality spectra (S/N>50 in the continuum near Halpha and Hbeta) were obtained in the spectral range ~4000 to 7500 \AA,

Electrical characterization of photovoltaic cell with low-concentration ratio square aperture concentrator

International Journal of Energy Research, 2017
Summary Improving photovoltaic (PV) system power output is the main target of research in this field. Using concentrators with PV systems should increase the power output and consequently reduce the power production costs. However, using concentrators with PV (CPV) system has a drawback of a higher PV system temperature, which affects the voltage ...

Spin Defects in Hexagonal Boron Nitride as 2D Strain Sensors

Advanced Functional Materials, EarlyView.
We demonstrate that boron‐vacancy (VB${\rm V}_{\rm B}$) centers in hexagonal boron nitride (hBN) enable quantitative strain sensing with sub‐micrometer resolution. Using this approach under continuously tunable in‐plane stress, we precisely quantify strain‐induced shifts of the E2g${\rm E}_{2{\rm g}}$ Raman mode in multilayer hBN, establishing VB${\rm ...

Self‐Hybridized Exciton‐Polariton Photodetectors From Layered Metal‐Organic Chalcogenolates

Advanced Functional Materials, EarlyView.
Self‐hybridized exciton‐polariton photodetectors are demonstrated using high refractive index mithrene, eliminating the need for top mirrors. This simplified architecture enables tunable sub‐bandgap photodetection via lower exciton‐polariton states and enhanced carrier transport through ultrafast polariton group velocities.
