Chromium (Cr) is the seventh most abundant chemical element in the Earth’s crust, and Cr(III) and Cr(VI) are common stable valence states of Cr. Several Cr-containing substances, such as FeOCr2O3 and stainless-steel products, exist in nature and in

Let R be a ring and m, n two fixed positive integers. In this article, R is defined to be left slightly (m, n)-coherent if each n-generated submodule of the left R-module Rm is (m, n)-projective. I...

Let (A, B) be a complete and hereditary cotorsion pair in the category of left R-modules. In this paper, the so-called Gorenstein projective complexes with respect to the cotorsion pair (A, B) are introduced. We show that these complexes are just the

Let R be a commutative Noetherian ring and C a semidualizing module. Based on a kind of Tate $$\mathcal {F}_C$$ -resolutions of modules constructed by Hu et al., in this paper, we introduce and investigate Tate homology for R-modules. For modules adm

Let 𝒲,𝒴,𝒳 be three classes of left R-modules. In this paper, we introduce and study (𝒲,𝒴,𝒳)-Gorenstein complexes as a common generalization of completely 𝒲-resolved complexes [26], Gorenstein projective (resp., injective) complex

Bulk aluminum matrix composites reinforced with carbon nano-onions (CNOs) were fabricated by a flake powder metallurgy route. Homogenous dispersion of CNOs (with an average size of ∼20 nm) was guaranteed by in situ polymer pyrolysis chemical vapor
