Phase transition of ZrN under pressure
(TAYLOR & FRANCIS LTD, 2-4 PARK SQUARE, MILTON PARK, ABINGDON OR14 4RN, OXON, ENGLAND, 2019)
A first principles constant pressure approach is carried out to probe the high-pressure behaviour of the rocksalt (RS) structured zirconium nitride (ZrN). The existence of first order reconstructive phase transition from ...
Very low density amorphous phase of zircon
(ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2019)
Using a reliable ab initio molecular dynamics method, we investigate the rapid solidification of the zircon melt. Accompanied by amorphization, a drastic volume expansion of 27% is perceived. This value is fairly larger ...
Hydrogenated amorphous boron nitride: A first principles study
(Elsevier, 2018)
The influence of hydrogenation on the atomic structure and electronic properties of amorphous boron nitride (?-BN) is investigated by using an ab-initio molecular dynamics technique. The structural evaluation of ?-BN and ...
An in-depth investigation of Mg-Zn-Ca metallic glasses: A first principles study
(Elsevier, 2018)
The atomic structures, glass forming evolutions, mechanical properties and high pressure behavior of Mg75Zn20Ca5 and Mg60Zn35Ca5 bulk metallic glasses, which are promising candidates for biomedical implants, have been ...
Solute aggregation in Ca72Zn28metallic glass
(Elsevier, 2018)
Solidification of the Ca72Zn28 melt is achieved by using both the thermal quenching and rapid pressurizing techniques in ab initio molecular dynamics simulations within a generalized gradient approximation. A chemical ...
Pressure-Induced Amorphization of MOF-5: A First Principles Study
(Wiley Online Library, 2018)
Amorphous metal-organic frameworks (MOFs) and the amorphization of crystalline MOFs under mechanical stimuli are attracting considerable interest in last few years. However, we still have limited knowledge on their atomic ...
Nanosegregated amorphous AlBN2 alloy
(TAYLOR & FRANCIS LTD2-4 PARK SQUARE, MILTON PARK, ABINGDON OR14 4RN, OXON, ENGLAND, 2016)
We use ab initio molecular dynamics simulations to create an amorphous AlBN2 model and find that it consists of nanosegregated two-dimensional hexagonal BN-like and tetrahedral AlN-like domains. These domains are somewhat ...
Amorphous BC5 from first principles calculations
(ELSEVIER, 2022)
A boron-substituted amorphous graphite (BC5) network is generated using a first principles molecular dynamics
simulation and its atomic structure and electrical and mechanical properties are discussed in details. The ...
Novel high-pressure phase of ZrO2: An ab initio prediction
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2015)
The high-pressure behavior of the orthorhombic cotunnite type ZrO2 is explored using an ab initio
constant pressure technique. For the first time, a novel hexagonal phase (Ni2In type) within P63/mmc
symmetry is predicted ...
Hexagonal nanosheets in amorphous BN: A first principles study
(ELSEVIER, 2015)
Amorphous boron nitrite is modeled by means of first principles molecular dynamics simulations and found to be almost chemically ordered in a stark contrast to the previous predictions. Its average coordination number is ...
