Systematic Experimental Charge Density: Linking Structural Modifications to Electron Density Distributions [PDF]

Chemistry Letters, 2014
Abstract Recent elegant examples illustrate the power of charge density analysis, employed in a systematic way, to link electron density distribution to molecular structure. This leads to new insights into important chemical systems and the effects of systematic modifications to them.

A Compact Spin‐Coated Graphene UWB Antenna for Breast Tumor Detection

Advanced Engineering Materials, EarlyView.
A compact, spin‐coated graphene ultra‐wideband patch antenna designed for breast tumor detection, capable of distinguishing between malignant and benign tumors. This innovative antenna can serve as an effective initial screening tool, particularly in resource‐limited settings such as rural areas, where access to advanced medical equipment like MRI and ...

Interplay between disorder and intersubband collective excitations in the two-dimensional electron gas

, 2001
Intersubband absorption in modulation-doped quantum wells is usually appropriately described as a collective excitation of the confined two-dimensional electron gas.

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Non-linear electrical response in a charge/orbital ordered $\Pr_{0.63}$Ca$_{0.37}$MnO$_3$ crystal : the charge density wave analogy

, 2003
Non-linear conduction in a charge-ordered manganese oxide Pr$_{0.63}$Ca$_{0.37}$MnO$_3$ is reported. To interpret such a feature, it is usually proposed that a breakdown of the charge or orbitally ordered state is induced by the current.

Application of Raman and Photoluminescence Spectroscopy to MgO‐C Refractories

Advanced Engineering Materials, EarlyView.
Visible to near infrared luminescence of MgO is studied on MgO‐C bricks and nominally pure MgO powder, with focus on two similar sharp high‐intensity signals, at 699 and 871 nm, each surrounded by symmetrical sidebands. The nature of these sidebands is investigated by temperature‐dependent spectroscopic measurements, confirming phonon involvement by ...

Enhancement of chirped density modulation in electron beam for generating ultrashort THz radiation pulse

Physical Review Accelerators and Beams
Ultrashort broadband THz radiation is an essential tool for investigating nonlinear phenomena and other frontier scientific research. Here, we propose a novel scheme that leverages the nonlinear longitudinal space-charge oscillation process to amplify ...

Generation of spin-polarized currents in Zeeman-split Tomonaga-Luttinger models

, 1995
In a magnetic field an interacting electron gas in one dimension may be described as a Tomonaga-Luttinger model comprising two components with different Fermi velocities due to the Zeeman splitting.

Tailored Hierarchical Porous Copper Architectures via Three Dimensional Printing and Pressure‐less Sintering for Next‐Generation Lithium‐Metal Batteries

Advanced Engineering Materials, EarlyView.
A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.
