Analysis and experimental study of oil well indicator diagram based on electric parameter method
Energy Reports, 2022 At present, the load diagram of pumping wells mostly uses load sensors to obtain load data. However, the load sensor is prone to mechanical fatigue during the measurement process, which results in measurement data drift distortion and large errors.

Advanced Functional Materials, EarlyView.Metal‐tetracene dimeric complexes are synthesized through the pyridyl coordination to either Pt(II) or Pd(II). Photophysical properties are systematically compared as a function of the metal using steady‐state and time‐resolved spectroscopy. The Pt(II) dimer exhibits efficient intramolecular singlet fission and subsequent intramolecular up‐conversion ...
