Seeded 2D epitaxy of large-area single-crystal films of the van der Waals semiconductor 2H MoTe2
We report a route for synthesizing wafer-scale single-crystalline 2H molybdenum ditelluride (MoTe2) semiconductors on an amorphous insulating substrate. In-plane 2D-epitaxy growth by tellurizing was triggered from a deliberately implanted single seed crystal. The resulting single-crystalline film completely covered a 2.5-centimeter wafer with excellent uniformity. The 2H MoTe2 2D single-crystalline film can use itself as a template for further rapid epitaxy in a vertical manner. Transistor arrays fabricated with the as-prepared 2H MoTe2 single crystals exhibited high electrical performance, with excellent uniformity and 10...

Scientists uncover new path toward treating a rare but deadly neurologic condition
(Massachusetts General Hospital) Molybdenum cofactor (Moco) is a compound that is little known but is essential for life. Children born without the ability to synthesize Moco die young. It has not been possible to create Moco supplements because the compound is so unstable. Studies in the nematode Caenorhabditis elegans suggest that by combining, Moco with certain proteins, it becomes stable and can repair deficiency. (Source: EurekAlert! - Biology)

Astronomical context of Solar System formation from molybdenum isotopes in meteorite inclusions
Calcium-aluminum–rich inclusions (CAIs) in meteorites are the first solids to have formed in the Solar System, defining the epoch of its birth on an absolute time scale. This provides a link between astronomical observations of star formation and cosmochemical studies of Solar System formation. We show that the distinct molybdenum isotopic compositions of CAIs cover almost the entire compositional range of material that formed in the protoplanetary disk. We propose that CAIs formed while the Sun was in transition from the protostellar to pre–main sequence (T Tauri) phase of star formation, placing Solar System ...

Chemical vapor deposition of layered two-dimensional MoSi2N4 materials
Identifying two-dimensional layered materials in the monolayer limit has led to discoveries of numerous new phenomena and unusual properties. We introduced elemental silicon during chemical vapor deposition growth of nonlayered molybdenum nitride to passivate its surface, which enabled the growth of centimeter-scale monolayer films of MoSi2N4. This monolayer was built up by septuple atomic layers of N-Si-N-Mo-N-Si-N, which can be viewed as a MoN2 layer sandwiched between two Si-N bilayers. This material exhibited semiconducting behavior (bandgap ~1.94 electron volts), high strength (~66 gigapascals), and excellent ambient ...

Metal-breathing bacteria could transform electronics, biosensors, and more
(Rensselaer Polytechnic Institute) When the Shewanella oneidensis bacterium " breathes " in certain metal and sulfur compounds anaerobically, the way an aerobic organism would process oxygen, it produces materials that could be used to enhance electronics, electrochemical energy storage, and drug-delivery devices. The ability of this bacterium to produce molybdenum disulfide -- a material that is able to transfer electrons easily, like graphene -- is the focus of research published in Biointerphases by a team of engineers from Rensselaer Polytechnic Institute.

Structural evidence for a dynamic metallocofactor during N2 reduction by Mo-nitrogenase
We report a 1.83-angstrom crystal structure of the nitrogenase molybdenum-iron (MoFe) protein captured under physiological N2 turnover conditions. This structure reveals asymmetric displacements of the cofactor belt sulfurs (S2B or S3A and S5A) with distinct dinitrogen species in the two αβ dimers of the protein. The sulfur-displaced sites are distinct in the ability of protein ligands to donate protons to the bound dinitrogen species, as well as the elongation of either the Mo–O5 (carboxyl) or Mo–O7 (hydroxyl) distance that switches the Mo-homocitrate ligation from bidentate to monodentate.

Evidence for an edge supercurrent in the Weyl superconductor MoTe2
We report evidence for the existence of a robust edge supercurrent in the Weyl superconductor molybdenum ditelluride (MoTe2). In a magnetic field B, fluxoid quantization generates a periodic modulation of the edge condensate observable as a "fast-mode" oscillation of the critical current Ic versus B. The fast-mode frequency is distinct from the conventional Fraunhofer oscillation displayed by the bulk supercurrent. We confirm that the fast-mode frequency increases with crystal area as expected for an edge supercurrent. In addition, weak excitation branches are resolved that display an unusual broken symmetry.

Dry reforming of methane by stable Ni-Mo nanocatalysts on single-crystalline MgO
Large-scale carbon fixation requires high-volume chemicals production from carbon dioxide. Dry reforming of methane could provide an economically feasible route if coke- and sintering-resistant catalysts were developed. Here, we report a molybdenum-doped nickel nanocatalyst that is stabilized at the edges of a single-crystalline magnesium oxide (MgO) support and show quantitative production of synthesis gas from dry reforming of methane. The catalyst runs more than 850 hours of continuous operation under 60 liters per unit mass of catalyst per hour reactive gas flow with no detectable coking. Synchrotron studies also show ...

For the latter, larger-diameter nanotubes that overcome strain effect were more readily synthesized.

The Pros and Cons of Standardized Testing
Independent organizations and FDA establish standardized test methods for materials and devices. The independent organizations (e.g., AAMI, ASTM, ISO, USP, etc.) create voluntary consensus standards. These may then become recognized by FDA, with some 1300 standards now found in the Recognized Consensus Standards database. For some of these standards, FDA includes a Rationale for Recognition statement with the curious language that the standard “is recognized on its scientific and technical merit and/or because it supports existing regulatory policies.” Recognized standards may in turn be...

Discovery and inhibition of an interspecies gut bacterial pathway for Levodopa metabolism
The human gut microbiota metabolizes the Parkinson’s disease medication Levodopa (l-dopa), potentially reducing drug availability and causing side effects. However, the organisms, genes, and enzymes responsible for this activity in patients and their susceptibility to inhibition by host-targeted drugs are unknown. Here, we describe an interspecies pathway for gut bacterial l-dopa metabolism. Conversion of l-dopa to dopamine by a pyridoxal phosphate-dependent tyrosine decarboxylase from Enterococcus faecalis is followed by transformation of dopamine to m-tyramine by a molybdenum-dependent dehydroxylase from Eggerthell...

How Much Cobalt Is in Your Metal Alloy?
The European Union is moving forward on its proposal to set risk management and labeling requirements relevant to the amount of cobalt in medical devices. The rule would be triggered at a limit of 0.1% by weight. This action is predicated on elevating the carcinogenic risk level of cobalt into a category known as 1b-Substances presumed to have carcinogenic potential for humans. At a minimum, compliance with these regulations will require knowledge of the amount of cobalt present in the metal alloys from which devices are made. For alloys that intentionally contain cobalt, this information should be readily available from t...

Building two-dimensional materials one row at a time: Avoiding the nucleation barrier
Assembly of two-dimensional (2D) molecular arrays on surfaces produces a wide range of architectural motifs exhibiting unique properties, but little attention has been given to the mechanism by which they nucleate.

The arrays assembled one row at a time, and the nuclei were ordered from the earliest stages and formed without a free energy barrier or a critical size. The results verify long-stand...
