Manipulating Nucleation Potency of Substrates by Interfacial Segregation
During solidification of metallic materials, heterogeneous nucleation occurs on substrates, either endogenous or exogenous. The potency of the substrates for nucleation is mainly dependent upon the atomic arrangements on the substrate surface, which are affected by the lattice misfit between the substrate and the nucleated solid, the surface roughness at atomic scale, and the chemical interaction between the substrates and the melt. Extensive examinations on metal/substrate (M/S) interfaces at atomic scale by the state-of-the-art aberration (Cs) corrected STEM and associated EDS and EELS have shown that alloying elements in liquid melts tend to segregate at the interfaces, leading to the formation of various 2-dimensional compounds (2DCs) or 2-dimensional solutions (2DSs), depending upon segregation behavior of the elements. For instance, Al3Ti 2DC and Ti2Zr 2DC at the Al/TiB2 interface, Y2O3 2DC at the Mg/MgO interface, and a Si-rich 2DS layer at Al-Si/TiB2 interface have been identified. Such interfacial segregations significantly affect nucleation potency of the substrates, resulting in either promoting or impeding the heterogeneous nucleation process during solidification.

Manganese-Zinc Ferrite Nanoparticles
A suitable amount of an addition of zinc, manganese, cobalt or nickel to the ferrite nucleus of the Nanoparticles (NPs) results in a higher magnetic resonance imaging contrast and an increase of saturation magnetization (Ms), which can lead to more efficient magnetic targeting. In particular, the introduction of zinc and manganese into the crystalline structure of the magnetic particle generates some changes in the material properties, enhancing their potential use in theranostic applications.

Manganese Oxide Carbon-Based Nanocomposite
The application of Manganese oxide (denoted as MnOx hereafter) in SCs was first reported in 1999. Since then, MnOx has been widely studied as an active, low-cost, and biofriendly ECs material. Why are manganese or its oxides are so appealing for SCs applications? First, manganese is a transition metal with five unpaired electrons, which possesses the most oxidation states, including the highest oxidation state (VII) in the entire periodic table. Due to its unique electronic structure, manganese is extremely redox-active, thus, it exists in several oxide forms. Second, Manganese is the most abundant transition metal among oxides which are pseudocapacitive. Third, MnOx exhibits high theoretical capacitance (1370 F/g for MnO2 for instance) with a wide positive potential window compared to other transition metal oxides.

Manganese and Manganese Oxide Nanoparticles
Manganese and its oxides in the form of nanoparticles could be a promising alternative for gadolinium-based contrast agents used in diagnostic imaging. Manganese, which is essential for living organisms as an enzyme cofactor, under excessive exposure—for example, due to water contamination or as an occupational hazard for welders—can lead to neurological disorders, including manganism—a condition similar to Parkinson’s disease. This review attempts to summarise the available literature data on the potential applications of manganese and manganese oxide nanoparticles.

Malt on Beer Flavour Stability
Delaying flavour staling has been one of the greatest and most significant challenges for brewers. The choice of suitable raw materials, particularly malting barley, is the critical starting point to delay the risk of beer staling. Malting barley and the malting process can have an impact on beer instability due to the presence of pro-oxidant and antioxidant activities. Malt contains various compounds originating from barley or formed during the malting process, which can play a significant role in the fundamental processes of brewing through their antioxidant properties.

MALDI MS-Based Investigations Targeting SARS-CoV-2
The urgent need to fight the COVID-19 pandemic has impressively stimulated the efforts of the international scientific community, providing an extraordinary wealth of studies. Improving the current laboratory testing methods and developing new rapid and reliable diagnostic approaches might be useful in managing contact tracing in the fight against both the original SARS-CoV-2 strain and the new, potentially fast-spreading CoV-2 variants. Mass Spectrometry (MS)-based testing methods and more specifically MALDI-MS have demonstrated without any doubt the great potential to overcome many unresolved analytical challenges arising from currently used laboratory testing assays, becoming an effective proteomic tool in several applications, including pathogen identification. With the aim of highlighting the challenges and opportunities that derive from MALDI-based approaches for the detection of SARS-CoV-2 and its variants, we extensively examined the most promising proofs of concept for MALDI studies related to the COVID-19 outbreak.

Main Raw Materials from Pineapple Biomass
Pineapple is a highly demanded fruit in international markets due to its unique appearance and flavor, high fiber content, vitamins, folic acid, and minerals. It makes pineapple production and processing a significant source of income for producing countries. The lignocellulosic biomass obtained from pineapple agro-industrial residues is mainly composed of cellulose, hemicellulose, and lignin; a compilation of information for these three compounds is presented below, with a specific focus on treatments and pretreatments that can be employed to obtain and purify them, as well as the most common applications of each.
