Novel superhard B-C-O phases predicted from first principles.

Shengnan Wang, Artem R. Oganov, +4 authors M Mahdi Davari Esfahani
Physical chemistry chemical physics : PCCP
2016

We explored the B-C-O system at pressures in the range 0-50 GPa by ab initio variable-composition evolutionary simulations in the hope of discovering new stable superhard materials. A new tetragonal… (More)

Improved Robust H-Infinity Estimation for Uncertain Continuous-Time Systems

Ai-Guo Wu, Huafeng Dong, Guang-Ren Duan
J. Systems Science & Complexity
2007

The design of full-order robust estimators is investigated for continuous-time polytopic uncertain systems. The main purpose is to obtain a stable linear estimator such that the estimation error… (More)

Novel lithium-nitrogen compounds at ambient and high pressures

Yanqing Shen, Artem R. Oganov, +4 authors Zhongxiang Zhou
Scientific reports
2015

Using ab initio evolutionary simulations, we predict the existence of five novel stable Li-N compounds at pressures from 0 to 100 GPa (Li13N, Li5N, Li3N2, LiN2, and LiN5). Structures of these… (More)

The phase diagram and hardness of carbon nitrides

Huafeng Dong, Artem R. Oganov, Qiang Zhu, Guang-Rui Qian
Scientific reports
2015

Novel superhard materials, especially those with superior thermal and chemical stability, are needed to replace diamond. Carbon nitrides (C-N), which are likely to possess these characteristics and… (More)

Superconductivity of novel tin hydrides (SnnHm) under pressure

M. Mahdi Davari Esfahani, Zhenhai Wang, +5 authors Xiang-Feng Zhou
Scientific reports
2016

With the motivation of discovering high-temperature superconductors, evolutionary algorithm USPEX is employed to search for all stable compounds in the Sn-H system. In addition to the traditional… (More)

Prediction of a new ground state of superhard compound B6O at ambient conditions

Huafeng Dong, Artem R. Oganov, +7 authors Qiang Zhu
Scientific reports
2016

Boron suboxide B6O, the hardest known oxide, has an Rm crystal structure (α-B6O) that can be described as an oxygen-stuffed structure of α-boron, or, equivalently, as a cubic close packing of B12… (More)

Nanotwinned Boron Suboxide (B6O): New Ground State of B6O.

Qi An, K. Madhav Reddy, Huafeng Dong, Ming-Wei Chen, Artem R. Oganov, William A. Goddard
Nano letters
2016

Nanotwinned structures in superhard ceramics rhombohedral boron suboxide (R-B6O) have been examined using a combination of transmission electron microscopy (TEM) and quantum mechanics (QM). QM… (More)

Unexpected stable phases of tungsten borides.

Changming Zhao, Yifeng Duan, +5 authors Artem R. Oganov
Physical chemistry chemical physics : PCCP
2018

Tungsten borides are a unique class of compounds with excellent mechanical properties comparable to those of traditional superhard materials. However, the in-depth understanding of these compounds is… (More)

New Tungsten Borides, Their Stability and Outstanding Mechanical Properties.

Alexander G Kvashnin, Hayk A Zakaryan, +5 authors Artem R. Oganov
The journal of physical chemistry letters
2018

We predict new tungsten borides, some of which are promising hard materials that are expected to be stable in a wide range of conditions, according to the computed composition-temperature phase… (More)
