Summary: A family of novel Os-Co-Ta-B high-temperature bulk metallic glasses (HTBMGs) with high glass transition temperature, Vickers microhardness, and compressive strength was fabricated by introducing high-modulus refractory metal Os and strong-covalent metalloid B. The impressive strength is attributed to the strong bond characteristics especially for Ta-Os and B-B bonds. The castable OsCo-based HTBMGs with superior mechanical properties and high thermal stabilities are significant for high-temperature applications as advanced structural materials.

Summary: BMGs' brittleness and work-softening hinder their wide applications as structural engineering materials, but can be improved by introducing the B2 phase to enhance plastic deformation and work-hardening. Although progress has been made, achieving enhanced tensile ductility and work-hardening in BMG composites remains a challenge.

Summary: This paper investigates the mold filling dynamics of BMGs in the supercooled liquid region through finite element simulations and experiments. The phase diagram predicting the reliable replication range of mold geometric parameters is determined. It is found that improperly designed molds can lead to complex filling dynamics and replication failure. This study provides new insights into the mold filling dynamics of highly viscous fluids and offers a guideline for thermoplastic molding of BMGs.

Summary: We observed pronounced low-temperature specific-heat Cp anomalies in the Mg59.5Cu22.9Ag6.6Gd11 bulk metallic glass (BMG). The behavior of the BMG resembled that of a heavy fermion system, with an extrapolated electron's temperature coefficient of up to 681.8 mJ/(molGd, Kappa 2) at 0 K. The enhancement of the conduction-electron effective mass below 7.5 K indicated that the BMG was not a free-electron-like solid. The excess specific heat was attributed to tunneling states and spin glass state, and the Boson peak temperature was higher than that of other BMGs.

Summary: Dissimilar TC4 titanium alloy and 316L stainless steel were successfully joined utilizing thermoplastic bonding with a Ti-based bulk metallic glass as the filler, forming multiple reaction layers and fine phase distribution. The superplastic flow of the BMG greatly promoted void shrinkage in the interfaces, resulting in a high strength of 225 MPa after diffusion at 695 degrees C for 60 minutes.

Summary: This study investigates the rapid synthesis of a nanoscale 3D porous structure on the surface of a Zr-based BMG by dealloying in solutions containing Cl- and F-. The addition of F- is found to lead to an increase in the corrosion potential gap between the components in the alloy. During the dealloying process, Zr, Ti, and Al are the main dissolved elements, and the formation of a porous structure is beneficial for improving the biomineralization activity of Zr-based BMGs.

Summary: The room temperature creep properties of Ir33Ni28Ta39 bulk metallic glass were investigated using nanoindentation. It was observed that the nanoindentation hardness decreased with increasing load, in accordance with the Nix-Gao model's indentation size effect. The creep stress exponent decreased from 1.86 to 1.17 with increasing load, showing a negative dependence on indentation depth. This suggests that the accumulation of free volume during deformation promotes more homogeneous creep deformation. Analysis of the creep displacement curve and the stress index indicated that the room temperature creep performance of Ir33Ni28Ta39 bulk metallic glass was insensitive to the loading rate, attributed to the sluggish atom motion caused by higher activation energy, which provides good creep resistance against different loading rates.

Summary: This study investigated the tensile and impact toughness properties of a Zr-based BMG fabricated via LPBF. Increasing the laser power at the borders mitigated near-surface defects, leading to improved strength and toughness. Near-surface LoFs were found to be more detrimental than core LoFs for BMGs, similar to crystalline alloys.

Summary: This research compared the frequency and magnitude of head impact events between Pee Wee and Bantam ice hockey players. It was found that Pee Wee boys experienced more head impacts from elbows and boards, while Bantam players had more head impacts to the glass. Both groups experienced similar frequency and magnitudes of strain to the brain. The study suggests reducing contact along the boards or removing body checking to reduce the incidence of brain trauma, and encourages ice hockey companies to develop protective devices and equipment strategies to reduce the risk of head injury for Bantam players.

Summary: This study investigated the print homogeneity of Ti-6Al-4 V alloy parts over a large build area using a production scale laser powder bed additive manufacturing system. It found that the part porosity increased slightly with distance from the gas flow inlet, but no significant differences were obtained for microstructural features and mechanical properties across the build area. The study also observed partial in-situ decomposition of a' -> a + Q phases during printing and a decrease in strength after HIP treatment.

Summary: This paper presents a microfluidic system capable of rapid and instrument-free detection of cytomegalovirus (CMV) by selectively extracting DNA from blood using a UV-assisted hyperbranched poly(beta-amino ester) (HPAE)-modified silica membrane. The extracted DNA can be used as a template for loop-mediated isothermal amplification (LAMP)-based detection of CMV with comparable results to commercially extracted templates. This system can be easily integrated with a nucleic acid amplification system for routine rapid testing of viral load in patient blood samples.

Summary: Currently, there is an urgent need for novel treatments for intrahepatic cholangiocarcinoma (ICC), the second most common type of primary liver cancer. This study identified CD44v5 as a potential target for a CD44v5-targeted antibody-drug conjugate (ADC) in ICC tumors. The ADC, H1D8-DC, demonstrated specific binding to CD44v5 and selective release of the drug in cancer cells, resulting in potent cytotoxicity at low concentrations. In vivo studies showed that H1D8-DC effectively targeted CD44v5-positive ICC cells and induced tumor regression without significant adverse effects.

Summary: In this article, a novel reconfigurable antenna with circular polarization on dual WiMAX bands (3.5, 5.8 GHz) using liquid metal switching capability is presented. Circular polarization reconfiguration is achieved by connecting the rectangular parasitic element (Pc) with the feed line using a liquid metal switch. The switch mechanism controls the liquid metal in microfluidic channels by applying a voltage to move and remove the high-conductivity liquid metal EGaIn on the microchannel. The proposed antenna has a simple configuration and compact size, and can generate dual WiMAX band with circular polarization (CP) performance by changing the state of the liquid metal switch, making it suitable for 5G wireless technology.
