A new generation of positron beams in the form of trap-based beam sources has been developed by positron trapping, confinement and accumulation in a Penning trap.

Screening of asafoetida mushroom strains with high polysaccharide productivity by low-energy ion implantation;

This research showed a high yield Pleurotus ferulae Lenzi strain by low energy ion implantation that extraction methods of polysaccharide from mycelium were studied by orthogonal experiments, rotation and combinational design of quadric regression the basis of determination of the extraction rates of polysaccharides.

Fe-based alloy design in surface metallurgy by plasma beam;

Effects of compress argon arc plasma beam scanning on microstructure and composition of electroless Ni-P alloy layer;

In view of the wear out of diesel engine cylinder liners,the high energy density plasma beam was applied to high speed scanning the liner surface of cylinder under atmospheric pressure and to make improvement treatment on the in-wall of cylinder liner partly so as to obtain the high hardness at hardened layer.

Experimental study on treatment of coke-plant wastewater with the aid of ion beams for inducing activated sludge;

Application of ion beam technology in material modification;

Formation of nanometer magnetic iron nitride films by ion beam enhanced deposition;

Experimental Research on Plasma Self-fluxing Ni60A Alloy Coating Appliedto Scraper Transporter;

Influence of electric current on the plasma beam hardening effect of the engine boron cast iron cylinder;

In the paper,an inter-metallic compound coating bonded well is successfully deposited on the sur- face of Al by plasma beam surface metallurgy on the basis of good mutual solubility of Cu and Al.
