Abstract. Fine particulate matter (PM2.5) is a severe air pollution problem in China. Observations of PM2.5 have been available since 2013 from a large network operated by the China National Environmental Monitoring Center (CNEMC). The data show a general 30 %–50 % decrease in annual mean PM2.5 across China over the 2013–2018 period, …

Acid protease is widely used in industries such as food processing and feed additives. In the study, low frequency magnetic field (LF-MF) as an aid enhances acid protease production by Aspergillus niger (A. niger). The study assessed mycelial biomass, the enzymic activity of the acidic protease and underlying mechanism. At low intensities, …

Magnetic separation is the process of separating magnetic materials from non-magnetic materials using a magnetic system. After World War II, this process became popular in scrap yards to separate metal particles from vehicles; however, the process is more sophisticated than that. In fact, one of the major benefits of magnetic separation …

line sweep for micro-area chemical analysis. The functional groups were investigated using a Nicolet iz10 Fourier transform infrared spectrometer (FTIR) (Thermo Scientific, MA, USA) in the range of 500–4000 cm−1. Magnetic analysis was performed using an MPMS SQUID VSM-094 vibrating sample magnetometer (VSM) (Equistar Chemicals, NJ, USA).

A significant increase in the magnetic field gradient can be achieved by placing ferromagnetic bodies (such as balls, mesh or steel wool) into the magnetic field of a separator (Frantz, 1937).These bodies (usually called a matrix), generate, when magnetised, a high local field gradient of the magnitude as high as 5 × 10 4 T/m. This …

Another complication to the Harris solution is evident in Fig. 1(c), where the black lines represent projections of the magnetic field lines onto the xz-plane.A typical trajectory of a thermal electron is illustrated by the blue line. Due to the finite B z component, the electrons stream along the magnetic field into the center of the current …

Low-grade iron ore mined from the earth is usually composed of several minerals, desirable and undesirable. Magnetic separation means applying a magnetic field of appropriate intensity, gradient, and other conditions to separate different minerals according to their differences in magnetic susceptibility. 9.3.
