Effect of Partial Replacement of Fly Ash by Decoration Waste Powder on the Fresh and Mechanical Properties of Geopolymer Masonry Mortar

This study aims to investigate the feasibility of using decoration waste powder(DWP)as a partial replacement for fly ash(FA)in the preparation of geopolymer masonry mortar,and to examine the effect of different DWP replacement rates(0%-40%)on the fresh and mechanical properties of the mortar.The results showed that each group of geopolymer masonry mortar exhibited excellent water retention performance,with a water retention rate of 100%,which was due to the unique geopolymer mortar system and high viscosity of the alkaline activator solution.Compared to the control group,the flowability of the mortar containing lower contents of DWP(10%and 20%)was higher.However,as the DWP replacement rate further increased,the flowability gradually decreased.The DWP could absorb the free water in the reaction system of geopolymer mortar,thereby limiting the occurrence of geopolymerization reaction.The incorporation of DWP in the mortar resulted in a decrease in compressive strength compared to the mortar without DWP.However,even at a replacement rate of 40%,the compressive strength of the mortar still exceeded 15 MPa,which met the requirements of the masonry mortar.It was feasible to use DWP in the geopolymer masonry mortar.Although the addition of DWP caused some performance loss,it did not affect its usability.

Nest decoration:Black feathers prevent Crested Mynas from nest usurpation

Nests are important structures for birds to raise their offspring and for signaling.Many birds incorporate feathers into the nest,since feathers were traditionally thought to serve the function of insulation.Hypotheses in recent years have considered that some birds place feathers in conspicuous locations in the nest for decoration to trigger a fear response in the competitors.In this study,we investigated whether decorative feathers could deter nest usurpation by Crested Mynas(Acridotheres cristatellus)by manipulating nest box contents.The results revealed that Crested Mynas preferred black feathers to white feathers as decorations and occupied nest boxes decorated with black feathers significantly less than those decorated with white feathers,suggesting that black decorative feathers in the nest could be more effective in preventing nest usurpation by Crested Mynas and that white decorative feathers may have other functions.The black feathers in the nest are prominently placed at the edge of the nest to convey the message that“this nest is occupied”or“the owner of this nest has been preyed upon”to visitor Crested Mynas,thus effectively preventing them from usurping the nest at a later stage.

Effects of crystallinity, {001}/{101} ratio, and Au decoration on the photocatalytic activity of anatase TiO_2 crystals

Anatase TiO2 nanocrystals and sub-microcrystals with truncated octahedral bipyramidal morphologies were prepared by direct calcination of TiOF2 precursors. The as-prepared TiO2 samples were thoroughly characterized by X-ray diffraction, Raman spectroscopy, field-emission scanning electron microscopy, N2 adsorption-desorption isotherms, X-ray photoelectron spectroscopy, and UV-visible diffuse spectroscopy. It was found that the crystallinity, grain size, and {001}/{101} ratio of the samples can be increased by raising the calcination temperature from 500 to 800℃. The higher crystallinity and {001}/{101} facet ratio resulted in an increase in both aqueous and gas-phase photocatalytic activities, by inhibiting the recombination and separation of electrons and holes. After selecting two TiO2 samples with high crystallinity and {001}/{101} ratio, Au nanoparticles were decorated on their surfaces, and the photocatalytic activity of the resulting samples under visible light illumination was studied. It was found that the visible light-induced photocatalytic activity increased by 2.6 and 4.8 times, respectively, upon Au decoration of the samples prepared by calcination of TiOF2 at 700 and 800℃.

Predator perception of detritus and eggsac decorations spun by orb-web spiders Cyclosa octotuberculata:Do they function to camouflage the spiders?

Camouflage is one of the most widespread and powerful strategies that animals use to make detection/recognition more difficult. Many orb-web spiders of the genus Cyclosa add prey remains, plant debris, moults, and/or eggsacs to their webs called web decorations. Web decorations resembling spider body colour pattern have been considered to camouflage the spider from predators. While this camouflage is obvious from a human＇s perspective, it has rarely been investigated from a predator＇s perspective. In this study, we tested the visibility of web decorations by calculating chromatic and achromatic contrasts of detritus and eggsae decorations built by Cyclosa octotubereulata, against four different backgrounds viewed by both bird （e.g., blue tits） and hymenopteran （e.g. wasps） predators. We showed that both juvenile and adult spiders on webs with detritus or egg-sac deco- rations were undetectable by both hymenopteran and bird predators over short and long distances. Our results thus suggest that decorating webs with detritus or eggsacs by C octotuberculata may camouflage the spiders from both hymenopteran and bird predators in their common habitats [Current Zoology 56 （3）： 379-387, 2010].

Decoration of carbon encapsulated nitrogen-rich MoxN with few-layered MoSe2 nanosheets for high-performance sodium-ion storage

Transition metal nitrides have become the focus of research in sodium ion batteries(SIBs)due to their unique metal properties and high theoretical capacity.However,the low actual capacity is still the main bottleneck for their application.Herein,using Mo-aniline frameworks as precursors,the carbon encapsulated nitrogen-rich Mo_(x)N is decorated by few-layered MoSe_(2) nanosheets(MoSe_(2)@Mo_(x)N/C-I)after the facile calcinating,selenizing,and nitriding.The carbon encapsulation can effectively strengthen the structural stability of Mo_(x)N.The nitrogen-rich Mo_(x)N and decoration of few-layered MoSe_(2) can create rich heterointerfaces and extra active sites for rapid sodium-ion storage,thus promoting reaction kinetics and improving actual capacity.The MoSe_(2)@Mo_(x)N/C-I as an anode achieves a large reversible capacity of 522.8 mAh g^(-1)at 0.1 A g^(-1),and 254.3 mAh g^(-1)capacity is obtained after 6000 cycles at 5.0 A g^(-1),showing signally improved sodium-ion storage properties.The storage mechanisms and kinetic behaviors are described systematically via the advanced testing techniques and density functional theory(DFT)calculations.It is found that the nitrogen-rich Mo_(x)N as the substrate is the basis of long cycling stability,and the few-layered MoSe_(2) are the key to improving actual capacity.This work indicates that the decoration of few-layered selenides has a broad application prospect in high-performance metal-ion batteries.

Identification of Grown-In Defects in CZ Silicon after Cu Decoration

Bulk Czochralski silicon crystals were decorated with Cu and characterized by transmission electron microscopy (TEM) with energy-dispersive spectroscopy (EDS), atomic force microscopy (AFM), optical microscopy (OM), scanning electron microscopy (SEM), and photoluminescence spectroscopy (PL). The vacancy-type core, oxidation-induced stacking faults (OISF) ring, nearly defect-free ring, and self-interstitial-type rich outer ring were delineated in the Si crystal wafer. At the surface of the Si crystal, vertical-horizontal line (V-H line) defects and windmill defects (W-defects) were formed instead of OISF. The families of growth planes and directions were expressed as {011} and for the V-H line and {010} and for W-defects, respectively. In addition to V-H line defects and W-defects, pits or voids and Si oxide with dissolved Cu were found in the Si crystal wafer.

First Principles DFT Study of Hydrogen Storage on Graphene with La Decoration

The properties of hydrogen storage on graphene with La decoration are investigated using a first-principles plane-wave pseudopotential method based on the density functional theory in this paper. The clustering problem of La decorated graphene is considered and B doping can solve it effectively in theory. We obtain the stable geometrical configuration of the modified system and the properties of hydrogen storage are excellent. It can absorb up to 6 H2 molecules with an average adsorption energy range of?–0.529 to –0.655 eV/H2, which meets the ideal range between the physisorbed and chemisorbed states for hydrogen storage. Furthermore, it is proved that the existence of La atom alters the charge distribution of H2 molecules and graphene sheet based on the calculation and analysis about the electronic density of states and charge density difference of the modified system. La atom interacts with hydrogen molecules through Kubas interaction. Thereby, it improves the performance of graphene sheet for hydrogen storage. The modified system exhibits the excellent potential to become one of the most suitable candidates for hydrogen storage medium at near ambient conditions with molecule state.
