Double Fe-impurity charge state in the topological insulator Bi$_2$Se$_3$ [PDF]
, 2017 The influence of individual impurities of Fe on the electronic properties of topological insulator Bi$_2$Se$_3$ is studied by Scanning Tunneling Microscopy. The microscope tip is used in order to remotely charge/discharge Fe impurities.

Camera System Performance Derived from Natural Scenes [PDF]
, 2020 The Modulation Transfer Function (MTF) is a well-established measure of camera system performance, commonly employed to characterize optical and image capture systems. It is a measure based on Linear System Theory; thus, its use relies on the assumption

Advanced Materials, EarlyView.Fluorene‐functionalized spiro‐phenothiazine (PTZ‐Fl) exhibits strong Li+ affinity and thermal stability, enabling a PCE of 25.75% in small‐area cells and 22.07% in 25 cm2 modules. Under ISOS‐L3 conditions, PTZ‐Flbased devices retain over 80% efficiency after 1000 hours, demonstrating superior stability and scalability compared to spiro‐OMeTAD for next ...

Effects of the postsunset vertical plasma drift on the generation of equatorial spread F
Progress in Earth and Planetary Science, 2018 Equatorial spread F (ESF) irregularities are caused by plasma instability processes in the equatorial ionosphere and especially related to plasma bubble phenomena in the topside F region.

Evaluation of Cottontail Pellets Collected in Suboptimal Conditions for DNA Analysis
Wildlife Society Bulletin, 2020 Occupancy monitoring of the New England cottontail (Sylvilagus transitionalis) relies on collections of fecal pellets made following a snowfall, and subsequent genetic screening to distinguish New England cottontail pellets from those of the eastern ...

The Effects of Gilts Housed Either in Group with the Electronic Sow Feeding System or Conventional Stall [PDF]
Asian-Australasian Journal of Animal Sciences, 2015 This experiment was conducted to assess the welfare and productivity of gestating gilts in groups with the electronic sow feeding (ESF) system compared to conventional stalls. A total of 83 gilts (Yorkshire×Landrace) were housed into individual stalls to

Advanced Materials, EarlyView.In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...
