Metal Incorporation

Recent work has indicated that iron (oxyhydr-)oxides are capable of structurally incorporating and releasing metals and nutrients as a result of Fe2+-induced iron oxide recrystallization. In the present paper, we briefly review the current literature examining the mechanisms by which iron oxides recrystallize and summarize how recrystallization affects metal incorporation and release. We also provide new experimental evidence for the Fe2+-induced release of structural manganese from manganese-doped goethite. Currently, the exact mechanism(s) for Fe2+-induced recrystallization remain elusive, although they are likely to be both oxide-and metal-dependent. We conclude by discussing some future research directions for Fe2+-catalysed iron oxide recrystallization.

Error Bars

We review the theoretical and experimental evidence for the candidacy of the [Formula: see text] and the [Formula: see text] for charmed tetraquarks. We briefly review the 't Hooft interaction's influence on the single-charm (C = 1)[Formula: see text] tetraquark mass spectrum: its consequences for other observed mesons such as the [Formula: see text], as well as its predictions of the (thus far) unobserved exotic tetraquark states. In particular we show that the small [Formula: see text] mass difference is naturally predicted by the tetraquark model, within the present experimental error bars, and thus may constitute the first "smoking gun" evidence for tetraquark existence. A short outlook of the possible future research directions is given.

The Impact

Although there has been extensive research being done in the field of Islamic finance, literature on sukuk are inadequate. This paper intends to present a thematic review of this subject matter. Through a thematic and chronological review, this paper is divided into the following themes; the first two sections are general i.e. we begin with an overview on the structure and nature of a sukuk contract, and the theories that have been adopted in sukuk research. While the remaining sections are separated according to the type of research i.e. a comparison between sukuk and bonds and investors’ perception of sukuk, and the impact of sukuk on economic growth. Besides providing a summary of the main points covered in current literature, this paper also highlight trends and issues on sukuk research and provide insight on limitation of current research as well as suggest future research directions.

Mass Degeneracy

We review the theoretical and experimental evidence for the candidacy of the [Formula: see text], [Formula: see text] and the [Formula: see text] for charmed tetraquarks. We briefly review the 't Hooft interaction's influence on the single-charm ( C =1)[Formula: see text] tetraquark mass spectrum: its consequences for other observed mesons such as the [Formula: see text], as well as its predictions of the (thus far) unobserved exotic tetraquark states. In particular we show that the near mass degeneracy of [Formula: see text] and [Formula: see text] was naturally predicted by the tetraquark model with 't Hooft interaction, and thus may constitute the first "smoking gun" evidence for tetraquark existence. A short outlook of possible future research directions is given.
