A method for making a composite and/or structured material includes: forming a lattice construction from a plurality of solid particles, the construction being formed so as to have one or more gaps between the particles; invading the lattice construction with a fluid material such that the fluid material at least partially penetrates the gaps; and, solidifying the material which invaded the lattice construction to form a composite material. In one suitable embodiment, the method further includes removing at least a portion of the lattice construction from the composite material thereby forming at the location of the removed portion one or more pores in the solidified material that invaded the construction.

A thermoplastic sulfur-polymer composite comprises a thermoplastic polymer, such as polyethylene and polystyrene; and a sulfur element. Such sulfur element functions as passive sulfur filler in this composite. The thermoplastic polymer is a polymer matrix; and the sulfur filler is dispersed in the polymer matrix. There is no chemical reaction occurs after the addition of the sulfur filler into the host polymer and no chemical bond formed between the polymer and the sulfur filler. The thermoplastic sulfur-polymer composite can be a nanocomposite by either adding certain nanofillers into the composite or making the sulfur filler as sulfur nanoparticles. With its similar physical properties and lower manufacturing costs, the thermoplastic sulfur-polymer composites are good alternatives of the respective pure polymers.

Macroporous beads and a method of manufacturing and using such macroporous beads. wherein the beads are distinguishable for use in a multiplex assay. Preferably, the beads are distinguishable by two or more unique fluorochromes, and at least some of the beads are magnetically responsive. In a preferred form, some of the macroporous beads have interior pores with a different moiety from the exterior surface, allowing beads with different attached functional groups.

A polyimide precursor solution contains resin particles and a polyimide precursor. The resin particles in the polyimide precursor solution have a volume particle size distribution with one or more peaks. The volume frequency of a peak having the highest volume frequency of the one or more peaks accounts for 90% to 100% of the total volume frequency of all peaks of the volume particle size distribution.
