Ag3XO4 (X = P, As, V)电子结构及光催化性质的第一性原理计算 = First-principles study on the electronic and photocatalytic properties of Ag3XO4 (X = P, As, V)
Published 2018“…In comparison to Ag3PO4, Ag3VO4 shows better photocatalytic stability, mainly due to the enhanced Ag―O bonds and improved Ag ion stability, but poorer photocatalytic activity in the visible light region mainly due to the presence of d orbital character at the conduction band minimum (CBM) and lower valence band maximum (VBM) potentials (2.335 V, vs NHE). …”

Reverse mathematics in lattice theory
Published 2018“…For distributive lattices, we have Birkhoff’s Representation Theorem (for finite distributive lattices) and Priestley’s Representation Theorem (for all bounded distributive lattices). In Chapter 2, we will show that Birkhoff’s Representation Theorem can be proved over RCA0. …”

Fabrication and characterization of graphene and carbon nanotube reinforced bioceramic nanocomposites
Published 2020“…When rGO and CNT hybrid were used as reinforcements, the optimum dispersion of rGOs and CNTs, and the strong interface bonding between the nanocarbons and HA matrixes were established in the composites. …”

Properties and mechanism of strain and piezoelectricity of hybrid molecular ferroelectrics
Published 2020“…The crystallography results indicate that this softening effect should originate from strength weakening on hydrogen and Cd-halide (Cd-X) bonds. In Chapter 4, the design strategy and discovery of the colossal shear strain in this OIHF will be presented. …”

Catalytic conversion of carbon dioxide to hydrocarbons
Published 2021“…However, for rPBE-vdW functional, we found that this is due to the erroneous treatment of C=O double bonds in gas phase CO2. Employing the benchmarked functional, CO2 methanation (46 elementary reactions) and DRM (38 elementary reactions) reactions were studied by combined DFT and MKM. …”

#Hooked? Extending the social cognitive model in examining the antecedents of problematic social network sites use among Singaporean adolescents and adults
Published 2018“…The results showed that the integrated model had good fit and received partial support for the hypothesized paths. Bonding and bridging capital, as well as various SNSs motivations (social connection, shared identities, and social investigation), were positively associated with mood alteration; only dependence on SNSs to derive shared identities was positively associated with both preference for online social interaction and mood alteration. …”

Topochemical fluorination of some Ruddlesden-Popper phases
Published 2017“…DFT calculations performed on La2SrCr2O7 suggest that this highly distorted A2/a (a<sup>-</sup>a<sup>-</sup>c<sup>-</sup>/a<sup>-</sup>a<sup>-</sup>c<sup>-</sup>) structure is stabilized by energy gains from the charge equalization and the improvement of chromium bonding environments associated with the unusual Sr/La distribution exhibited by this phase (the 12-coordinate A-sites are occupied by 82(2)% La<sup>3+</sup> and 18(2)% Sr<sup>2+</sup>).…”

Development of resistive random access memory for next-generation embedded non-volatile memory application
Published 2021“…In this thesis, the progressive analysis of the resistive switching I-V characteristics has been adopted to explore the upper and lower bounds of the DC parameters. The significant changes of the I-V curves have been observed when the DC parameters are out of the ranges. …”

Surface engineering to manipulate solar energy for thermal management
Published 2023“…It was proven that under electrostatic field, water evaporation rate was enhanced up to 15.6% compared to a normal steam generator under the same sunlight illumination, due to weakened hydrogen bonding networks, smaller water clusters as revealed by in-situ Raman spectroscopy. …”
