Controlled Moderate Interfacial Reaction Facilitates High‐Strength Low‐Resistivity Barrier Layer for Half‐Heusler Thermoelectrics

Advanced Science, EarlyView.
The barrier layer is designed comprehensively by thermal expansion coefficient and interfacial reaction energy to yield a controlled interfacial reaction. Ultimately, the Co25Fe50Ni25/half‐Heusler joint simultaneously achieves low contact resistivity and high bonding strength.

Elemental ratios in stars vs planets

, 2015
Context. The chemical composition of planets is an important constraint for planet formation and subsequent differentiation. While theoretical studies try to derive the compositions of planets from planet formation models in order to link the composition

Enabling Metal‐Based Soft Robotics Through Investment Casting

Advanced Intelligent Systems, EarlyView.
Vacuum investment casting enables manufacturing of compliant soft robotic structures out of AA7075 high‐strength aluminum alloy. Additively manufactured patterns are converted into metal soft robotic structures addressing long lasting challenges like durability and nonlinearity of elastomer‐based soft robotics.

Davisite, CaScAlSiO_6, a new pyroxene from the Allende meteorite [PDF]

, 2009
Davisite, ideally CaScAlSiO_6, is a new member of the Ca clinopyroxene group, where Sc^(3+) is dominant in the M1 site. It occurs as micro-sized crystals along with perovskite and spinel in an ultra-refractory inclusion from the Allende meteorite.

Improvement of water absorption behavior and mechanical properties of woven jute fiber‐reinforced epoxy composites with waste eggshell filler

Polymer International, EarlyView.
This study investigates the influence of waste eggshell powder on the water absorption and mechanical properties of jute fiber‐reinforced epoxy composites. Optimal eggshell filler content (2 wt%) significantly enhances composite performance by reducing water absorption and improving mechanical properties.

Low Mg/Si planetary host stars and their Mg-depleted terrestrial planets

, 2012
Simulations have shown that a diverse range of extrasolar terrestrial planet bulk compositions are likely to exist, based on the observed variations in host star elemental abundances.

Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.

Cosmochemical Consequences of Particle Trajectories During FU Orionis Outbursts by the Early Sun

, 2012
The solar nebula is thought to have undergone a number of episodes of FU Orionis outbursts during its early evolution. We present here the first calculations of the trajectories of particles in a marginally gravitationally unstable solar nebula during an

The GAPS Programme with HARPS-N at TNG. X. Differential abundances in the XO-2 planet hosting binary [PDF]

, 2015
Binary stars hosting exoplanets are a unique laboratory where chemical tagging can be performed to measure with high accuracy the elemental abundances of both stellar components, with the aim to investigate the formation of planets and their subsequent ...

Diet, phenology and body size shape nutrient release by songbirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,
