Structures and Properties of β-Titanium Alloys Doped with Trace Transition Metals: A Density Functional Theory Study
We systematically calculate the structure, formation enthalpy, formation free energy, elastic constants and electronic structure of Ti0.98X0.02 system by density functional theory (DFT) simulations to explore the effect of transition metal X (X = Ag, Cd, Co, Cr, Cu, Fe, Mn, Mo, Nb, Ni, Pd, Rh, Ru, Tc, and Zn) on the stability mechanism of β-titanium. Based on our calculations, the results of formation enthalpy and free energy show that the adding small amounts of X is beneficial to the thermodynamic stability of β-titanium. This behavior is well explained by the density of state (DOS). However, the tetragonal shear moduli of Ti0.98X0.02 systems are negative, indicating that β-titanium doping with a low concentration of X is still elastically unstable at 0 K. Therefore, we theoretically explain that β-titanium doped with trace transition metal X is unstable in the ground state.

Structures and Properties of $β$-Titanium Doping Trace Transition Metal Elements: a Density Functional Theory Study
We systematically calculate the structure, formation enthalpy, formation free energy, elastic constants and electronic structure of Ti$_{0.98}$X$_{0.02}$ system by density functional theory (DFT) simulations to explore the effect of transition metal X (X=Ag, Cd, Co, Cr, Cu, Fe, Mn, Mo, Nb, Ni, Pd, Rh, Ru, Tc, and Zn) on the stability mechanism of $\beta$-titanium. Based on our calculations, the results of formation enthalpy and free energy show that adding trace X is beneficial to the thermodynamic stability of $\beta$-titanium. This behavior is well explained by the density of state (DOS). However, the tetragonal shear moduli of Ti$_{0.98}$X$_{0.02}$ systems are negative, indicating that $\beta$-titanium doping with a low concentration of X is still elastically unstable at 0 K.

Surface wettability aging behavior of aramid fiber III after oxygen plasma treatment
Aramid Fiber III was modified by oxygen plasma treatment. The fiber surface wettability before and after different oxygen plasma treatment pressure, and surface wettability aging behavior were observed by Dynamic Contact Angles Analysis (DCAA), respectively. The results showed that aramid fiber surface wettability were increased after oxygen plasma treatment. The total surface free energy increased from 37.78 mJ/m2 for untreated sample to 69.63 mJ/m2 with 40 Pa plasma treated fiber. The fiber surface wettability decreased slowly with storage time in air. The fiber surface wettability decreased from 67.79 mJ/m2 for 20 Pa plasma-treated sample to 63.85 mJ/m2 after 30 days.
