Introduction Reduced-activation ferritic/martensitic (RAFM) steels are presently considered as one of the most realistic candidates for the structural materials of fusion blanket systems [1, 2].
Several typical RAFM steels are selected as primary blanket structural materials in the prospective International Thermonuclear Experimental Reactor (ITER) including F82H, JLF-1, EUROFER97, 9Cr2WVTa and CLAM steel [3~5].The SCRAM steel is a new RAFM steel [6], which was developed by our group using Cr-W-V-Ti-N system instead of Cr-W-V-Ta system.
Helium is one of the major nuclear transmutation products in structural materials of fusion reactors [7].
It is well known that appropriate annealing treatment can eliminate the internal residual stress of materials, restrain grains from growing up, adjust microstructure structure and composition and then enhance the plasticity and toughness of materials [9].

Abstract.
Although they have long been a familiar source of natural materials, neglected bamboo forests have increased due to the lack of successors.
The strength tests of bamboo fibers were conducted using four kinds of materials – raw materials in an untreated air-dried state (Ra), raw materials heat-dried in a drying furnace at 110°C for 24 hours followed by air-drying (He), raw materials boiled in water for 30 minutes to remove sugar followed by air-drying (Bo), and finally, raw materials soaked in water that contained 30% hydrogen peroxide for 60 minutes for sterilization followed by rinsing in water (HO).

Since the behaviour following sudden column loss is likely to be inelastic and possibly implicate catenary effects, both geometric and material nonlinearities are considered.
Mainly, the capacity design of columns as key elements may have a beneficial effect on the robustness by delaying or preventing the progressive collapse, especially for high-rise buildings designed for high seismic zones.
The steel material used for all beams and columns is S275, with a lower-bound yield and tensile strength values equal to 275 MPa and 410 MPa, respectively.
The structural model for nonlinear analysis incorporates material and geometric nonlinearities.

Abstract.
Introduction Acid catalysis plays a key role in many important reactions in the chemical and petroleum industries, and in environmentally benign chemical processes [1].
Recently, some workers reported zirconia-supported tungsten oxide or molybdenum oxide as alternative materials in reactions requiring strong acid sites [2,3].
