Energy resolution is an important index to measure the performance of nuclear instruments, and the noise, ballistic defect and accumulation of nuclear pulse signal are important factors affecting energy resolution. In the digital nuclear spectrum measurement system, the digital shaping algorithm is usually used to process the nuclear pulse signal to improve the energy resolution of the measurement system. In this paper, the algorithm is simulated by the theoretical formula of spike pulse forming...

The traditional periodic table of chemical elements believes that the properties of chemical elements are closely related to the outer electrons. This paper introduces history and innovation and entrepreneurship thinking to explore the specific characteristics of each electron. Because the new arrangement cycle of electrons is exactly the same as that of the Chinese historical dynasties, the properties of each electron are mapped by the gradual evolution characteristics of the Chinese historical...

Polyvinylidene fluoride (PVDF) is employed in a wide range of devices based on its excellent mechanical, optical, high thermal, piezoelectric, pyroelectric, and ferroelectric characteristics. In the current investigation, the pristine and neodymium oxide (Nd2O3) nanoparticles embedded polyvinylidene fluoride (PVDF) thick films were prepared via solution casting method. The Nd2O3 nanoparticles were synthesized via hydrothermal tech ...

Lasers are used to modify the surface
morphology, crystallinity, chemical composition, reactivity and resistivity of
polymer surfaces. In this work, several cellulose acetate membranes were
exposed by ArF excimer laser, 193 nm, at 2 - 20 UV pulses, with 100 - 350
mJ/pulse energy, at 1 Hz pulse repetition rate. Characterization techniques
viz. Fourier transform infrared spectroscopy (FTIR), Contact angle
measurement, Scanning electron microscopy (SEM), At ...
