X‐Ray Absorption Sensitivity at 5d$5d$ Edges of High‐Valent Light Actinides to Crystal‐Field Strength and Covalency Effects

open access: yesChemistry – A European Journal, EarlyView.
Analysis of x‐ray absorption spectra of U(VI) and U(V) oxides indicates an important role of U 5f−O$5f-\rm{O}$ 2p$2p$ charge transfer for increasing the 5f$5f$ occupancy and thereby affecting the ground state properties. ABSTRACT The 5f$5f$ states were probed in ThO2$\rm{ThO}_2$ and U(VI) and U(V) oxides using x‐ray absorption spectroscopy at the ...

Open-Loop Beamforming Technique for MIMO System and Its Practical Realization

open access: yesInternational Journal of Antennas and Propagation, 2011
The concept of close-loop beamforming for MIMO system was well known proposed the singular value decomposition on channel matrix. This technique can improve the capacity performance, but the cost of feedback channel and the complexity processing discard

Double Sided Traction Force Microscopy: A Method to Confine Cells for Physiologically Relevant Force Measurements

open access: yesCytoskeleton, EarlyView.
ABSTRACT In this paper we describe a technique to make a confined environment of variable stiffness that is suitable for high‐resolution live‐cell imaging. This versatile and adaptable technique enables cell confinement between soft elastic surfaces made from polyacrylamide gels.

A High‐Performance Oxidized Graphene for Dendrite‐Free Anodes and Kinetically Enhanced Cathodes of Aqueous Zn‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Oxidized graphene rich in carboxylic acid groups obtained via a simple electrochemical exfoliation route is shown to tackle the main challenges of aqueous Zn‐ion batteries (AZIBs), specifically short Zn anode cycle life and sluggish cathode reaction kinetics.

Implementation of a New and Modified Scheme of Butler Matrix for C-Band Applications with Enhanced Characteristics [PDF]

open access: yesRadioengineering, 2020
In this paper, the structure of a miniaturized broadband 4 × 4 Butler matrix is presented. All components of the proposed feeding network are designed in a way that they have the smallest electrical size and acceptable performance in the C band.

Numerical Analysis and Optimization of a Continuous‐Flow pH‐TRC for Steady‐State Low‐Grade Waste Heat Recovery

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A steady‐state numerical model is established for a continuous‐flow pH‐TRC for low‐grade waste heat recovery. Based on carbonate and bicarbonate electrolytes, the influences of operating conditions and electrode structure on pH‐driven power generation are clarified.

Array Antenna Feeding Network Design for 5G MIMO Applications

open access: yesElectrica, 2019
Emerging smart antenna systems requiredifferent beam patterns of multiple antennas. Although adjustable phaseshifters are mostly used in continuous-beam systems, the Butler matrix is usedin switching-beam systems due to its low cost and easy fabrication.
