3. Results and Discussion 3.1. ViscosityThe viscosity of the slurry is a critical determinant of its fluidity. The test results are presented in . As shown in a, as the UFA content increases up to 25%, there is a notable reduction in viscosity, thereby enhancing the slurry’s fluidity. a shows the mechanism of action of UFA in cement. Based on these results, it can be observed that UFA can fill the gaps between cement particles, playing a filling role and increasing the density of the slurry.

Transition from Schottky to Ohmic contacts in 2D Ge/GaAs heterostructures with high tunneling probability† The metal–semiconductor (M–S) contact is usually an Ohmic contact or a Schottky contact, which greatly affects the electronic properties of devices, and it remains a huge challenge to realize a low-resistance Ohmic contact in a metal–semiconductor junction (MSJ).
