Journal ArticleDOI
In situ Raman Study of Phase Stability of α-Li3V2(PO4)3 upon Thermal and Laser Heating
Nellymar Membreno,Penghao Xiao,Kyusung Park,John B. Goodenough,Graeme Henkelman,Keith J. Stevenson +5 more
TL;DR: In this paper, the calculated Raman spectrum of α-Li3V2(PO4)3 provided by density functional theory is presented along with symmetry assignments for all of the calculated and observed modes through Raman microscopy.
Journal ArticleDOI
Communication: From graphite to diamond: reaction pathways of the phase transition.
Penghao Xiao,Graeme Henkelman +1 more
TL;DR: A new reaction mechanism between graphite and diamond with nucleation characteristics that has a lower activation energy than the concerted mechanism is found, resolving a conflict between theory and experiment.
Journal ArticleDOI
Calculations of oxide formation on low-index Cu surfaces
TL;DR: The kinetic mechanisms found provide a qualitative explanation of the observed oxidation of the low-index Cu surfaces, and have a relatively low reaction energy barrier for O2 dissociation, even at high oxygen coverage.
Journal ArticleDOI
Interfacial adhesion between graphene and silicon dioxide by density functional theory with van der Waals corrections
TL;DR: In this article, the van der Waals (vdW) interaction was used to model the interaction strength of the SiO2 surface structures due to surface reactions with water, and it was shown that vdW forces are required to accurately model the graphene/SiO2 interface with DFT and that the adhesion energy is underestimated by empirical force fields commonly used in atomistic simulations.
Journal ArticleDOI
Kinetic Pathways Templated by Low-Temperature Intermediates during Solid-State Synthesis of Layered Oxides
Jianming Bai,Wenhao Sun,Jianqing Zhao,Dawei Wang,Penghao Xiao,Jun Young Peter Ko,Ashfia Huq,Gerbrand Ceder,Gerbrand Ceder,Feng Wang +9 more
TL;DR: In this paper, a synthetic control of high-nickel (Ni) systems is proposed for lithium-ion batteries, which can be used to control the synthesis of synthetic control systems.
