“…This applies not only for secondary phosphates as in the current study, but also to low soluble nanocrystalline hydroxyapatite ceramics as shown by Gustavsson et al [24–26]. The latter has - due to the high specific surface area - a strong affinity to a broad range of mono- and divalent cations [27, 28], which leads to a non-linear adsorption of calcium (50% adsorption) and potassium (8%) ions from cell culture media [26]. This in turn has a strong effect especially for bone forming cells, whereby a Ca 2+ depletion of the medium is known to dramatically decrease osteoblast proliferation and differentiation [29, 30].…”

Background In vitro cell testing of degradable bioceramics such as brushite or monetite is often challenging due to the ion release into or adsorption from the culture medium. These ionic changes are then mostly responsible for cell proliferation and activity, which prohibits the investigation of effects originating from surface topography or further material modifications.MethodsHere, we aimed to solve this problem by developing a pre-conditioning regime following the repeated immersion of brushite and monetite samples in various Ca2+, Mg2+ and PO4 3− containing electrolytes, followed by studying ion adsorption / release as well as changes in phase composition and in vitro cytocompatibility with MG63 cells.ResultsThe results demonstrated that by using DMEM cell culture medium in a ratio of 10 ml/sample was sufficient to minimize changes of ionic composition after 7 d with a daily change of the medium. This leads to changes of the surface composition with dissolution of the brushite phase. In turn, this also positively influences the in vitro cytocompatibility with a 2–3 fold higher cell number and cell activity on the DMEM pretreated surfaces.ConclusionsControlled sample washing prior to cell testing using DMEM medium seems to be a valuable procedure not only to stabilize the pH during cell culture but also to maintain ion concentrations within a cell friendly range.

“…The studies of the formation, functionalization, and application of borazine derivatives have been summarized in several review articles. [9,14] In 2020, the Kinjo group reported a BN derivative I-BN3 containing four boron and two nitrogen atoms. [15] Neutral B 4 N 2 ring with the six π-electron system was prepared by the reduction of the tetrachloro-substituted precursor with potassium graphite (KC 8 ) in the presence of trimethyl phosphine (PMe 3 ) (Scheme 2).…”

It has been computationally proposed that there are more than 200 possible isomeric structures for the C6H6 molecule, among which benzene (CH)6 represents the most thermodynamically stable molecule and its chemistry has been extensively developed. Three benzene valence isomers (CR)6, namely, prismane, Dewar benzene, and benzvalene, have also been synthesized to date. Incorporation of heteroatoms in the skeletal frameworks allows access to inorganic analogues of benzene and its valence isomers, which have attracted considerable attention due to their peculiar structural and electronic features. Experimentally, more than 30 examples of inorganic benzene and its valence isomers have been developed and characterized so far. In this contribution, their synthesis and characterization, as well as their stability and chemical properties, are discussed.

Nanomaterials have already contributed to many innovative products in the consumer markets. Constant efforts are directed at attaining unique morphologies and reduction in size. Exponential growth in research is thus involved in the synthesis of the novel nanomaterials. Boron and its compounds with distinct functional and structural properties find extensive usage in a variety of fields ranging from nuclear technology to electronics, ceramics, etc. Also, due to their non-toxicity, they are considered an attractive intermediate in the healthcare and cosmetic industry. The majority of reviews on boron and its compounds are focused on morphologies and the structure of the boron compound obtained. Here, we offer a comprehensive review of the unique properties of the major boron compounds: boron carbide (B4C), boron nitride (BN), and heterostructures with metals and organic compounds. In each section, we also describe the subsequent synthesis routes and the challenges associated with them. We have also summarized the various morphologies and shapes reported to be associated with boron and its compounds. In recent years, however, primary research on boron nanoparticle (BNP) has focused on non-toxic/greener and energy-efficient synthesis routes. The usage and production of pure BNPs in the industry are very scarce and are often associated with nanoclusters of boron and other elements. The intricate structural design and low purity of the nanoproducts formed make BNP synthesis challenging. Thus, in the last section, we summarize the challenges and outlook of the current research with future prospects in the area of BNP research.
