Abstract
A summary of the resource.
The respiratory infection COVID-19 is caused by the severe acute respiratory syndrome coronavirus 2 (SARSCoV- 2), which continues to spread worldwide causing more than a million deaths yearly. Despite the rapid development of vaccines for prevention, a critical need remains for therapeutic agents to combat the established infection. With this goal in mind, we conducted a target- (SARS-CoV-2 chemotrypsin-like protease, MPro) and phenotypic-based screening of a subset of compounds from our in-house chemo-library. The selected compounds have been previously studied in different diseases’ models. About 45 % of the analyzed compounds displayed inhibitory activity against MPro in the low μM range. Additionally, 3 out of 26 tested compounds (11 %) against SARS-CoV-2 displayed true anti-viral activity and (SI > 2). One of them belongs to the chloroquine-heterocycle chemotype, which was previously reported to hold anti-SARS-CoV-2. The remaining two novel hits belong to the polyhedral‑boron system, metallacarborane and dicarba-closo-dodecaborane chemotypes, which have not been previously reported for this anti-viral activity. In addition to targeting MPro, the chloroquine- and the metallacarborane-derivative, but not the dicarba-closo-dodecaborane, also inhibited the papain-like protease of SARS-CoV-2.

Abstract
A summary of the resource.
By means of first-principles calculations, we study the structural, electronic and mechanical properties of the newly synthesized boron–oxygen holey framework (Chem. Comm. 2018, 54, 3971). It has a planar structure formed by B3O3 hexagons, which are joined via strong covalent boron–boron bonds. The six B3O3 units are connected with six-fold symmetry exhibiting a large hole with a surface area of 23 Å2, which is ideal for the adsorption of alkalis. For neutral alkalis, we found that the adsorption energy of potassium is 14 and 12 kcal mol−1 larger than those determined for sodium and lithium, respectively. In contrast, for alkali cations, there is a clear preference for lithium over sodium and potassium. With regard to its electronic properties, it is an insulator with an electronic band gap of 5.3 eV, at the HSE level of theory. We further investigate the effect of strain on the band gap and find it a less efficient technique to tune the electronic properties. The wide optical gap of B3O3 can be utilized in ultraviolet (UV) applications, such as UV photodetectors, etc. Additionally, the 2D elastic modulus of B3O3 (53.9 N m−1) is larger than that of Be3N2, silicene, and germanene. Besides, we also report bilayer and graphite-like bulk B3O3 and furthermore, find that the optoelectronic properties of the bilayer can be tuned with an external electric field. The great tunability of optical properties from UV to the visible range offers a vast range of applications in optoelectronics.

Abstract
A summary of the resource.
The structure, stability, electronic properties and chemical reactivity of X/B/N triple‐doped graphene (TDG) systems (X=Al, Si, P, S) are investigated by means of periodic density functional calculations. In the studied TDGs the dopant atoms prefer to be bonded to one another instead of separated. In general, the XNB pattern is preferred, with the exception of sulfur, which favors the SBN motif. The introduction of a third dopant results in a negligible decrease of the cohesive energies with respect to the dual‐doped graphene (DDG) counterparts. Thus, it is expect that these systems can be prepared soon. For SiNB TDG, the introduction of the B dopant reduces the gap opening at the K point and restores the Dirac cones that are destroyed in SiN DDG. On the contrary, for PNB TDG, the bandgap is increased with respect to PN DDG, probably because the introduction of B weakens the PN bonding, and thus the electronic structure is rather similar to that of P‐doped graphene. Finally, with regard to the reactivity of the TDGs, for AlNB, PNB, and SNB the carbon atoms are more reactive than in their AlN, PN, and SN DDG counterparts. On the contrary, the reactivity of SiNB is lower than that of SiN DDG. Therefore, to increase the reactivity of graphene, Al, P, and S should be combined with BN motifs

Abstract
A summary of the resource.
We compared resistance to decay, mold fungi, termites and insect larvae of particleboards incorporated with the raw boron minerals ulexite and colemanite to that of particleboards impregnated with the commercial boron preservative zinc borate, or boric acid plus a borax mixture. We also quantified water absorption, thickness swell and boron release of particleboards. Ulexite had the best decay resistance, and colemanite had the best termite resistance. However, ulexite and colemanite were not as effective as zinc borate or the boric acid/borax mixture in preventing mold growth. In general, the boric acid/borax mixture combination was more effective against Anobium larvae than the other treatments. Less boron was released by specimens containing zinc borate and colemanite than by those containing ulexite or the boric acid/borax mixture. In general, water absorption and thickness swell were similar among the different treatments, but both were slightly higher in the ulexite-incorporated specimens. Further mechanical tests will be needed to evaluate the particleboard properties and thereby the compatibility of these boron minerals with various manufacturing processes.
