“…Isotopic oxygen exchange experiments between 16 66 . The number of exchanged oxygens on ZrO 2 was found to be greater than the theoretical number of surface oxygen species implying that bulk oxygen atoms participated in the exchange 66 . 3 Hydroxyl species and the interaction of water and hydrogen on monoclinic zirconia…”

“…One approach to hydroxyl studies is to replace hydrogen with its heavier isotope deuterium using D 2 or D 2 O, or to replace 16 O with 18 O, all of which are easily observable in both IR and mass spectrometry. OD groups, known as deuteroxyls, have been investigated by many groups 19,21,24,42,44,56,59,61,87 while oxygen-labeling studies are more scarce 66,69,81 .…”

Tantalum hafnium carbide (Ta4HfC5) powders were synthesized by solvothermal treatment and carbothermal reduction reactions from an inorganic hybrid. Tantalum pentachloride, hafnium chloride, and phenolic resin were used as the sources of tantalum, hafnium, and carbon, respectively. Pyrolysis of the complexes at 1000°C/1 h initiated the carbothermal reduction to result in multiplex phases including tantalum carbide and hafnium oxide which after heat treatment at 1400°C–1600°C transformed to single‐phase solid solution Ta4HfC5 by solid solution reaction. The mean crystallite size of Ta4HfC5 particles was less than 80 nm, and the composition of Ta, Hf, and C elements was near stoichiometric and homogeneously distributed in the powder samples. XRD pattern for Ta4HfC5 powders was analyzed.

“…The sensitive film of the ammonia sensor was zirconium dioxide prepared by the sol-gel method [13,14] as follows: zirconium n -propoxide (Zr (OC 3 H 7 ) 4 , 70 wt%) precursor was dissolved in ethylene glycol (C 2 H 4 (OH) 2 ) with stirring for 3 hours until the solution was mixed uniformly. The mixed solution was added into the NaOH precipitant with stirring for 1 hour.…”

The study presents an ammonia microsensor integrated with a readout circuit on-a-chip fabricated using the commercial 0.18 μm complementary metal oxide semiconductor (CMOS) process. The integrated sensor chip consists of a heater, an ammonia sensor and a readout circuit. The ammonia sensor is constructed by a sensitive film and the interdigitated electrodes. The sensitive film is zirconium dioxide that is coated on the interdigitated electrodes. The heater is used to provide a working temperature to the sensitive film. A post-process is employed to remove the sacrificial layer and to coat zirconium dioxide on the sensor. When the sensitive film adsorbs or desorbs ammonia gas, the sensor produces a change in resistance. The readout circuit converts the resistance variation of the sensor into the output voltage. The experiments show that the integrated ammonia sensor has a sensitivity of 4.1 mV/ppm.
