Based on the homology principle in advanced pharmaceutical chemistry, a new high efficiency and low toxicity collector, O-butyl S-(1-chloroethyl)carbonodithioate, was designed. By using molecular simulation technology, MS (Materials Studio) was used to build the molecular model of the collector. The molecular structure was relaxed and optimized. The process of interaction between reagent and mineral surface was simulated and the interaction energy of reagent and mineral surface was calculated by density functional theory (DFT). The interaction process of the new collector and butyl xanthate on the mineral surface and the interaction energy of these two reagents and mineral surface were compared. The molecular structure of the new collector was designed from the perspective of the difference of the interaction energy between the reagents and the mineral surface. According to the results of molecular design and modelling, the new collector was synthesized. The flotation tests of pure minerals and real ores were carried out to verify the new collector. The experimental results showed that the collector has the characteristics of low toxicity, high selectivity, moderate collecting ability and low cost, and it is more suitable for flotation of the complex and refractory copper sulfide with low grade and fine dissemination.

Based on the Shared mind model, this paper tries to find out and verify the factors that influence the teamwork ability of college sports associations. Based on some theoretical research, this paper proposes three factors that may affect teamwork ability: communication, trust and the use of information technology. This paper collects data through questionnaire survey, and USES SPSS statistical analysis software to carry out descriptive statistics and hypothesis testing on the data. The results show that communication, trust and the use of information technology have positive effects on the teamwork ability of college sports associations. To effectively improve team collaboration, team members should actively use information technology, such as chat sharing software, to assist the team in completing tasks. At the same time, team members should also enhance the level of trust and form good communication.

A deep understanding of the role of Ca in geopolymers exposed to various environments is essential for geopolymerization. This work evaluates the role of Ca by observing the behavior of hierarchically calciferous geopolymers under different environments including air, carbonization and freezing-thawing cycles. The structural and morphological differences between the geopolymers and the related mechanisms in various environmental conditions are assessed based on compressive strength, brunauer emmett teller, X-ray diffraction, fourier transform infrared spectoscopy, nuclear magnetic resonance spectroscopy and scanning electron microscopy measurements. It is found that two kinds of geopolymer gels, calcium silicate hydrate and sodium aluminosilicate hydrate, are formed in the geopolymerization of blast furnace slag and fly ash. Regardless of the specific air, carbonization or freezing-thawing cycle environment, the former gel dominates the properties in low Ca geopolymers, while the latter gel determines the properties in medium and high Ca geopolymers. Moreover, the carbonization environment enables calciferous geopolymers with higher surface areas and smaller pore sizes. Such adequate pore structures can significantly improve the performance of the geopolymers. This study presents novel insights into the influence of Ca on geopolymerization and in strengthening geopolymer properties.

Hard tissue engineering scaffolds were prepared by micro-extrusion freeforming using biphase calcium phosphate powders. This technique allows both the shape and a hierarchical pore structure within the shape to be designed on the computer and promptly downloaded onto a three-axis building platform. We report on the implementation of six types of design in which the systematic exploration of different void structures can be achieved using one sample configuration. In this way, void sizes from 50 μm to 500 μm are built into a lattice such that histological studies can deliver the maximum information from the minimum of testing. This technique also allows multi-scale hierarchies of void structure to be built into one component such that large voids intended for vascularisation can accompany smaller recesses which can host osteoblast development as well as conferring mechanical strength.

The dissolution behaviour of calcium phosphate filaments made by extrusion freeforming for hard tissue scaffolds was measured. The solubility of filaments with different HA/beta-TCP ratios sintered at temperatures from 1,100 to 1,300 degrees C was measured under simulated physiological conditions (tris buffer solution: tris(hydroxyl) methyl-aminomethane-HCl), pH 7.4, 37 degrees C). Calcium and phosphate concentrations were measured separately by inductively coupled plasma (ICP) atomic emission spectroscopy. Surface morphologies and composition before and after immersion were analyzed by SEM and EDS. The results clearly show that as the beta-TCP content increased, the dissolution increased. Higher sintering temperatures, with consequent closure of surface pores, resulted in lower dissolution. Examination of the surface suggested dissolution on preferred sites by pitting.

Lattices consisting of hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP) mixtures were prepared by extrusion freeforming to serve as bone substitute structures in which both shape and structural hierarchy are determined by computer control. Fine ceramic filaments were prepared from a non-aqueous, solvent-based, ceramic–polymer paste and sintered at temperatures from 1100 to 1300 °C. The characteristics of the sintered filaments were investigated because this determines the resulting microporosity and phase content while the higher levels of porosity are computer controlled. The effects of HA/β-TCP ratio and sintering temperature on the microstructure, density, shrinkage and final phase content were studied. These results provide a design reference for hard tissue engineering scaffolds built from these materials.
