    Description: The Global Consortium for the Classification of Fungi and fungus-like taxa is an international initiative of more than 550 mycologists to develop an electronic structure for the classification of these organisms. The members of the Consortium originate from 55 countries/regions worldwide, from a wide range of disciplines, and include senior, mid-career and early-career mycologists and plant pathologists. The Consortium will publish a biannual update of the Outline of Fungi and funguslike taxa, to act as an international scheme for other scientists. Notes on all newly published taxa at or above the level of species will be prepared and published online on the Outline of Fungi website (https://www.outlineoffungi.org/), and these will be finally published in the biannual edition of the Outline of Fungi and fungus-like taxa. Comments on recent important taxonomic opinions on controversial topics will be included in the biannual outline. For example, ‘to promote a more stable taxonomy in Fusarium given the divergences over its generic delimitation’, or ‘are there too many genera in the Boletales?’ and even more importantly, ‘what should be done with the tremendously diverse ‘dark fungal taxa?’ There are undeniable differences in mycologists’ perceptions and opinions regarding species classification as well as the establishment of new species. Given the pluralistic nature of fungal taxonomy and its implications for species concepts and the nature of species, this consortium aims to provide a platform to better refine and stabilise fungal classification, taking into consideration views from different parties. In the future, a confidential voting system will be set up to gauge the opinions of all mycologists in the Consortium on important topics. The results of such surveys will be presented to the International Commission on the Taxonomy of Fungi (ICTF) and the Nomenclature Committee for Fungi (NCF) with opinions and percentages of votes for and against. Criticisms based on scientific evidence with regards to nomenclature, classifications, and taxonomic concepts will be welcomed, and any recommendations on specific taxonomic issues will also be encouraged; however, we will encourage professionally and ethically responsible criticisms of others’ work. This biannual ongoing project will provide an outlet for advances in various topics of fungal classification, nomenclature, and taxonomic concepts and lead to a community-agreed classification scheme for the fungi and fungus-like taxa. Interested parties should contact the lead author if they would like to be involved in future outlines.

    Notes: In this work, triethyl phosphate (TEP) was used to bioactivating titanium. Titanium platesgrafted with TEP were immersed in a two times concentrated simulated body fluid (2SBF) toinvestigate deposition of hydoxyapatite (HA) on the surface. A phosphate buffer solution (PBS) withbovine serum albumin (BSA) was used to evaluate adsorption of protein on the grafted titaniumsurface. The morphology, component and structure of samples were examined by scanning electronicmicroscopy, attenuated total reflection Fourier transform infrared spectroscopy and X-ray diffractionrespectively. The concentration change of BSA in adsorption test was examined with theultraviolet-visible absorption spectra (UV). The analyses showed that TEP grafted onto the titaniumsurface. In 2SBF, calcium and phosphate ions deposited spontaneously onto the grafted titaniumsurface and formed a HA coating with a network-like microporous structure after being immersed for3 days. The coating consisted of HA particles with 180-265nm in thickness and 72-85nm in width.The diameter of the micropores was about 200nm. The HA coating appeared better uniformity thanthat on the modified titanium using phosphoric acid. BSA rapidly adsorbed onto the grafted titaniumsurface at first half an hour and then the adsorption quantity almost kept constant. These resultsindicate that TEP grafting is an effective approach to modify bioactivity of titanium

    Notes: Bone-like hydroxyapatite (HA) coatings were fabricated on titanium implants by aself-assembled technique and biomimetic method. After titanium plates were oxidized in a mixture ofH2SO4/H2O2, a hexadecanoic acid self-assembled onto titanium surfaces. Contact angles of water andtricresyl phosphate on the surfaces were measured to characterize the self-assembled monolayer(SAM) and confirm the presence of the functional group. The titanium plates with SAM were used tofabricate HA coatings. In the simulate body fluid (SBF) with and without bovine serum albumin(BSA), Ca2+ and PO43- ions could spontaneously deposit onto the titanium surfaces and formbone-like HA coatings. The morphology, component and structure of samples were examined byscanning electronic microscopy, X-ray photoelectron spectroscopy, X-ray diffraction and attenuatedtotal reflection Fourier transform infrared spectroscopy. The results suggested that the SAM caninduce the formation of the nano-HA coating with a network and microporous structure. For thebiomimetical HA coating induced by HDA-SAM, BSA could modulate the growth of HA crystal anddecreased the grain size

    Notes: In this paper, we emphasize the temperature- and exposure-dependent development of low-energy electron diffraction patterns,measured quantitatively during oxidation of Ni(100) at 80 to 400 K. We find a strong temperature dependence in the development of LEED patterns associated with NiO. NiO(111) is favored by adsorption temperatures below 300 K, whereas a (7×7)-like structure is favored by adsorption temperatures of 300 to 400 K. Room temperature is a "crossover'' point between these two forms of the oxide. The final oxide depth is independent of adsorption temperature and, therefore, of epitaxial orientation, between 80 and 400 K. When the sample is heated in vacuum after adsorption, massive rearrangements take place above 500 K. Some of the nickel reverts to metallic nickel covered by a c(2×2) oxygen overlayer, and some forms NiO crystallites which are probably deeper than the initial oxide skin. Effectively, the parent oxide disproportionates into a less-oxygen-rich phase and a more-oxygen-rich phase. This is again independent of the orientation of the initial oxide epitaxy.

    Notes: An ultrahigh-vacuum compatible sample manipulator which incorporates rotation and a Dewar for sample cooling is described. The rotation is accomplished using a differentially pumped rotary seal made of two Teflon O rings and the temperature of the sample can be controlled from 30 K to over 1600 K.
