Composition and Resulting Band Alignment at the TiO2/InP Heterointerface: A Fundamental Study Combining Photoemission Spectroscopy and Theory

open access: yesAdvanced Functional Materials, EarlyView.
The chemical composition and band alignment are systematically investigated at the TiO2/InP heterointerface. Thin TiO2 films are deposited by ALD on atomically ordered, P‐terminated p‐InP(100). By combining UPS, XPS, and ab initio molecular dynamics, the atomistic structure and electronic alignment are revealed.

Current in Wave Driven Plasmas

open access: yes, 1985
A theory for the generation of current in a toroidal plasma by radio-frequency waves is presented. The effect of an opposing electric field is included, allowing the case of time varying currents to be studied.

Simulation of microalgal growth in a continuous photobioreactor with sedimentation and partial biomass recycling [PDF]

open access: yes, 2016
Microalgae are considered as promising feedstocks for the third generation of biofuels. They are autotrophic organisms with high growth rate and can stock an enormous quantity of lipids (about 20 \u2013 40% of their dried cellular weight).

Environmental Impacts and Cost Analysis of Perovskite Nanocrystals for Light‐Emitting Diode Applications

open access: yesAdvanced Sustainable Systems, EarlyView.
CsPbBr₃ colloidal nanocrystals synthesized via hot‐injection (HI) and microwave‐assisted (MW) methods exhibit excellent optoelectronic properties for LEDs. Although the MW route is more energy‐efficient and eco‐friendly in the lab, industrially, its environmental impacts are similar, but with lower costs.

A State Observer Design for Simultaneous Estimation of Charge State and Crossover in Self-Discharging Disproportionation Redox Flow Batteries [PDF]

open access: yes, 2019
This paper presents an augmented state observer design for the simultaneous estimation of charge state and crossover flux in disproportionation redox flow batteries, which exhibits exponential estimation error convergence to a bounded residual set.

Static VAr Compensator Control Using Phasor Measurement Unit Feedback Signals for Voltage Stability Improvement in Power Systems

open access: yesEnergy Science &Engineering, EarlyView.
Static VAr Compensators can provide significant improvement in power system stability. Phasor Measurement Units are used in combination with SVCs for fast and reliable control of its operation. By combining the VAr control and Voltage Regulation control methods of the SVC, superior performance is obtained.

Corrections to Scaling Neutrino Mixing: Non-zero $\theta_{13}, \delta_{CP}$ and Baryon Asymmetry [PDF]

open access: yes, 2015
We study a very specific type of neutrino mass and mixing structure based on the idea of Strong Scaling Ansatz (SSA) where the ratios of neutrino mass matrix elements belonging to two different columns are equal.

Ultraviolet‐C Vertical‐Cavity Surface‐Emitting Lasers with Precise Cavity Length Control

open access: yesLaser &Photonics Reviews, EarlyView.
Here, ultraviolet‐C (UVC) vertical‐cavity surface‐emitting lasers (VCSELs) with precise (<1% over 0.9 mm ×$\times$ 1.2 mm) cavity length is demonstrated by employing photo‐assisted electrochemical etching. This novel technique allows device membranes to be separated from the growth substrate and receive a highly‐reflective dielectric mirror on both ...
