| 3 | Effect of Powder Particle Shape on the Properties of In Situ Ti–TiB Composite Materials Produced by Selective Laser Melting显示文摘This work studied the preparation of starting powder mixture influenced by milling time and its effect on the particle morphology(especially the shape) and, consequently, density and compression properties of in situ Ti–Ti B composite materials produced by selective laser melting(SLM) technology. Starting powder composite system was prepared by mixing 95 wt% commercially pure titanium(CP-Ti) and 5wt% titanium diboride(TiB 2) powders and subsequently milled for two different times(i.e. 2 h and 4 h).The milled powder mixtures after 2 h and 4 h show nearly spherical and irregular shape, respectively.Subsequently, the resultant Ti–5 wt% TiB 2 powder mixtures were used for SLM processing. Scanning electron microscopy image of the SLM-processed Ti–Ti B composite samples show needle-shape TiB phase distributed across the Ti matrix, which is the product of an in-situ chemical reaction between Ti and TiB 2during SLM. The Ti–Ti B composite samples prepared from 2 h and 4 h milled Ti–TiB 2 powders show different relative densities of 99.5% and 95.1%, respectively. Also, the compression properties such as ultimate strength and compression strain for the 99.5% dense composite samples is 1421 MPa and 17.8%, respectively, which are superior to those(883 MPa and 5.5%, respectively) for the 95.1% dense sample. The results indicate that once Ti and TiB 2 powders are connected firmly to each other and powder mixture of nearly spherical shape is obtained, there is no additional benefit in increasing the milling time and, instead, it has a negative effect on the density(i.e. increasing porosity level) of the Ti–Ti B composite materials and their mechanical properties. | Hooyar Attar Konda G.Prashanth Lai-Chang Zhang Mariana Calin Ilya V.Okulov Sergio Scudino Chao Yang Jürgen Eckert | 2015 | Journal of Materials Science & Technology2015，31，10： | 12 |

| 5 | Targeted Antimicrobial Therapy Against Streptococcus mutans Establishes Protective Non-cariogenic Oral Biofilms and Reduces Subsequent Infection显示文摘Aim Dental biofilms are complex communities composed largely of harmless bacteria. Certain pathogenic species including Streptococcus mutans (S. mutans) can become predominant when host factors such as dietary sucrose intake imbalance the biofilm ecology. Current approaches to control S. mutans infection are not pathogen-specific and eliminate the entire oral community along with any protective benefits provided. Here, we tested the hypothesis that removal of S. mutans from the oral community through targeted antimicrobial therapy achieves protection against subsequent S. mutans colonization. Methodology Controlled amounts of S. mutans were mixed with S. mutans-free saliva, grown into biofilms and visualized by antibody staining and cfu quantization. Two specifically-targeted antimicrobial peptides (STAMPs) against S. mutans were tested for their ability to reduce S. mutans biofilm incorporation upon treatment of the inocula. The resulting biofilms were also evaluated for their ability to resist subsequent exogenous S. mutans colonization. Results S. mutans colonization was considerably reduced (9 ± 0.4 fold reduction, P=0.01) when the surface was preoccupied with saliva-derived biofilms. Furthermore, treatment with S. mutans-specific STAMPs yielded S. mutans-deficient biofilms with significant protection against further S. mutans colonization (5 minutes treatment: 38 ± 13 fold reduction P=0.01; 16 hours treatment: 96 ± 28 fold reduction P=0.07). Conclusion S. mutans infection is reduced by the pre- sence of existing biofilms. Thus maintaining a healthy or 'normal' biofilm through targeted antimicrobial therapy (such as the STAMPs) could represent an effective strategy for the treatment and prevention of S. mutans colonization in the oral cavity and caries progression. | Li-na Li Li-hong Guo Renate Lux Randal Eckert Daniel Yarbrough Jian He Maxwell Anderson Wen-yuan Shi | 2010 | International Journal of Oral Science2010，2，2： | 5 |

| 10 | Development and evaluation of a safe and effective sugar-free herbal lollipop that kills cavity-causing bacteria显示文摘Dental caries (tooth decay) is caused by a specific group of cariogenic bacteria, like Streptococcus mutans, which convert dietary sugars into acids that dissolve the mineral in tooth structure. Killing cariogenic bacteria is an effective way to control or prevent tooth decay. In a previous study, we discovered a novel compound (Glycyrrhizol A), from the extraction of licorice roots, with strong antimicrobial activity against cariogenic bacteria. In the current study, we developed a method to produce these specific herbal extracts in large quantities, and then used these extracts to develop a sugar-free lollipop that effectively kills cariogenic bacteria like Streptococcus mutans. Further studies showed that these sugar-free lollipops are safe and their antimicrobial activity is stable. Two pilot human studies indicate that a brief application of these lollipops (twice a day for ten days) led to a marked reduction of cariogenic bacteria in oral cavity among most human subjects tested. This herbal lollipop could be a novel tool to promote oral health through functional foods. | Chu-hong Hu Jian He Randal Eckert Xiao-yang Wu Li-na Li Yan Tian Renate Lux Justin A.

| 15 | New para-magnetic(CoFeNi)(50)(CrMo)(50-x)(CB)x(x=20,25,30)non-equiatomic high entropy metallic glasses with wide supercooled liquid region and excellent mechanical properties显示文摘In this study,high entropy metallic glasses(HEMGs)were developed through a combination of concepts for designing metallic glasses(main element+transition metal+metalloid element)and high-entropy alloys(more than five elements,each element having an atomic concentration between 5 at.%and 35 at.%).The developed metallic glass alloys are composed of Co-Fe-Ni main elements,transition metals(Cr,Mo)and metalloid elements(C,B).Moreover,the present work reports the thermal,mechanical and magnetic properties of(CoFeNi)(50)(CrMo)(50-x)(CB)x alloys with x=20,25,30.The developed as-spun HEMGs exhibit typical paramagnetic properties even for a high amount of ferromagnetic elements(Co,Fe,and Ni)and have high elastic modulus(103–160 GPa)and hardness(14–27 GPa),thus possessing mechanical properties similar to well-known Co-based metallic glasses(Co-Cr-Mo-C-B system).In addition,some of the bulk samples prepared with a diameter of 2 mm form bulk metallic glasses with a high compressive strength around 3.5 GPa.The mechanisms determining the stability of the supercooled liquid,as well as the paramagnetic and mechanical properties for the developed non-equiatomic HEMGs,are discussed. | Jeong Tae Kim Sung Hwan Hong Jin Man Park Jürgen Eckert Ki Buem Kim | 2020 | Journal of Materials Science & Technology2020，36，8： | 3 |

| 19 | Mechanical Properties,Damage and Fracture Mechanisms of Bulk Metallic Glass Materials显示文摘The deformation,damage,fracture,plasticity and melting phenomenon induced by shear fracture were investi- gated and summarized for Zr-,Cu-,Ti-and Mg-based bulk metallic glasses(BMGs)and their composites.The shear fracture angles of these BMG materials often display obvious differences under compression and tension, and follow either the Mohr-Coulomb criterion or the unified tensile fracture criterion.The compressive plas- ticity of the composites is always higher than the tensile plasticity,leading to a significant inconsistency.The enhanced plasticity of BMG composites containing ductile dendrites compared to monolithic glasses strongly depends on the details of the microstructure of the composites.A deformation and damage mechanism of pseudo-plasticity,related to local cracking,is proposed to explain the inconsistency of plastic deformation under tension and compression.Besides,significant melting on the shear fracture surfaces was observed.It is suggested that melting is a common phenomenon in these materials with high strength and high elastic energy,as it is typical for BMGs and their composites failing under shear fracture.The melting mechanism can be explained by a combined effect of a significant temperature rise in the shear bands and the instantaneous release of the large amount of elastic energy stored in the material. | Zhefeng ZHANG Fufa WU Guo HE Eckert | 2007 | Journal of Materials Science & Technology2007，23，6： | 3 |
