Comparison of Mg-based liquid metal ion sources for scalable focused-ion-implantation doping of GaN

April 18, 2024
Author(s)
Aaron Katzenmeyer, Michael Titze, Sam Frisone, Tony Ohlhausen, Anthony Flores, Deanna Campbell, Bingjun Li, Yongqiang Wang, Jung Han, Edward Bielejec, Rachel Goldman
We compare the suitability of various magnesium-based liquid metal alloy ion sources (LMAIS) for scalable focused-ion-beam (FIB) implantation doping of GaN. We consider GaMg, MgSO4•7H2O, MgZn, AlMg, and AuMgSi alloys. Although issues of oxidation (GaMg)

Linkage conversions in single-crystalline covalent organic frameworks

Baoqiu Yu, Rui-Biao Lin, Gang Xu, Zhi-Hua Fu, Hui Wu, Wei Zhou, Shanfu Lu, Qian-Wen Li, Yucheng Jin, Jing-Hong Li, Zhenguo Zhang, Hailong Wang, Zier Yan, Xiaolin Liu, Kang Wang, Banglin Chen, Jianzhuang Jiang
Single-crystal X-ray diffraction is a powerful characterization technique that enables the determination of atomic arrangements in crystalline materials. Growing or retaining large single crystals amenable to it has, however, remained challenging with

Possible Genetic Risks from Heat-Damaged DNA in Food

June 1, 2023
Author(s)
Yong Woong Jun, Melis Kant, Erdem Coskun, Pawel Jaruga, Miral M. Dizdar, Eric T. Kool
Consumption of foods prepared at high temperatures has been associated with numerous health risks. To date, the chief identified source of risk has been small molecules produced in trace levels by cooking and react with healthy DNA upon consumption. Here

Gut Microbe-Targeted Choline Trimethylamine Lyase Inhibition Improves Obesity Via Rewiring of Host Circadian Rhythms

Growth and Characterization of Large (Y,La)TiO 3 and (Y,Ca)TiO 3 Single Crystals

December 29, 2021
Author(s)
Sajna Hameed, Joseph Joe, Laxman Thoutam, Javier Garcia Barriocanal, Biqiong Yu, Guichuan Yu, S. Chi, Tao Hong, Travis Williams, John W. Freeland, Peter M. Gehring, Zhijun Xu, Masaaki Matsuda, Bharat Jalan, Martin Greven
The Mott-insulating rare-earth titanates (RTiO 3, R being a rare-earth ion) are an important class of materials that encompasses interesting spin-orbital phases, ferromagnet-antiferromagnet and insulator-metal transitions. The growth of these materials has

In-situ near-field probe microscopy of plasma processing

December 27, 2018
Author(s)
Alexander Tselev, Jeffrey Fagan, Andrei Kolmakov
There exists a great necessity for in situ nanoscale characterization of surfaces and thin films during plasma treatments. To address this need, the current approaches rely on either ‘post mortem' sample microscopy, or in situ optical methods. The latter

Kinetic Modeling of Heptane Combustion and PAH Formation

February 19, 2017
Author(s)
Valeri I. Babushok, Wing Tsang
Kinetics of heptane combustion was studied through numerical modeling. High temperature kinetic model of heptane combustion was constructed. The model includes four main blocks of reactions: C1-C2 chemistry, which is based on Grimech-3.0 model; block of C3

Influence of Hydrocarbon Moiety of DMMP on Flame Propagation in Lean Mixtures

July 7, 2016
Author(s)
Gregory T. Linteris, Valeri I. Babushok, Viswanath R. Katta, Fumiaki Takahashi
Phosphorus-containing compounds (PCCs) have been found to be significantly more effective than CF3Br for reducing burning velocity when added to stoichiometric hydrocarbon-air flames. However, when added to lean flames, DMMP (dimethylmethylphosphonate) is

High-resolution X-ray emission spectroscopy with transition-edge sensors: present performance and future potential

May 1, 2015
Author(s)
W.Bertrand (Randy) Doriese, Joseph Fowler, Daniel Swetz, Cherno Jaye, Daniel A. Fischer, Carl D. Reintsema, Douglas Bennett, Leila R. Vale, Gene C. Hilton, Dan Schmidt, Joel Ullom, Jens Uhlig, Ujjwal Mandal, Galen O'Neil, Luis Miaja Avila, Young I. Joe, wilfrid fullagar, Fredrick P. Gustafsson, Dharma Kurunthu, Villy Sundstrom
X-ray emission spectroscopy (XES) is a powerful element-selective tool to analyze the oxidation states of atoms in complex compounds, determine their electronic configuration, and identify unknown compounds in challenging environments. Until now the low
