Liquid-phase electron microscopy of electrochemical processes: Microcells configuration, corrosion of aluminium current collector and lithium-ion battery cycling

Electrochemical liquid-phase electron microscopy (ec-LPEM) has been seen as a promising technique for revealing new insights into electrochemical phenomena that occur at the micro- and nanoscale levels, particularly at the solid-liquid interface. Specifica ...

Influence of Testing Temperature on the Mechanical Performance of Brazed Conventionally and Additively Manufactured 316L Stainless Steel Joints

Andreas Mortensen, Raphaël Charvet

In this work, brazed joints between samples of 316L stainless steel (316LSS) are formed using the Ag155 brazing filler metal. As an additional aspect of the investigation, the joints combine stainless steel formed by conventional processing and by additive ...

On-chip Germanium nanowires for hole spin qubits

Santhanu Panikar Ramanandan

The creation of a universal quantum computer that can solve complex problems beyond the reach of classical computers - the so-called "quantum supremacy" - is an open challenge. For this to become a reality, a large number of qubits should be integrated in ...

Bioprinting of piezoresistive organohydrogel networks for advanced real-time mechanosensing in engineered tissue models

Esther Amstad

Understanding biomechanics in 3D cell culture is key to advancing tissue engineering, yet integrating real-time sensing into soft tissues remains a challenge. We developed a stretchable, piezoresistive hydrogel by combining PEDOT:PSS with a polyvinyl alcoh ...

Hypereutectic Al-Ce-X (X=Mn, = Mn, Cr, V, Mo, W) alloys fabricated by laser powder-bed fusion

Christian Leinenbach

We characterize the microstructures and high-temperature mechanical properties of Al-2Ce and ternary Al-2Ce-1X (at.%) alloys fabricated by laser powder-bed fusion (LPBF), where X = Mn, Cr, V, Mo, and W are slow-diffusing transition metals. All ternary allo ...

Solute strengthening of prism edge dislocations in Mg alloys

William Curtin, Masoud Rahbarniazi

The poor ductility of hcp Mg is attributed to the low activity of non-basal slip systems and so activation of prismatic slip can aid ductility in rolled sheets by providing three additional < a > Burgers vector slip systems. Experimental studies show that ...

3D deep learning for enhanced atom probe tomography analysis of nanoscale microstructures

Ye Wei

Quantitative analysis of microstructural features on the nanoscale, including precipitates, local chemical orderings (LCOs) or structural defects (e.g. stacking faults) plays a pivotal role in understanding the mechanical and physical responses of engineer ...

Complexity of crack front geometry enhances toughness of brittle solids

John Martin Kolinski, Chenzhuo Li, Xinyue Wei

Brittle solids typically fail by growth and propagation of a crack from a surface flaw. This process is modelled using linear elastic fracture mechanics, which parameterizes the toughness of a material by the critical stress intensity factor, or the prefac ...

Zn/P ratio and microstructure defines carrier density and electrical transport mechanism in earth-abundant Zn3-xP2+y thin films

Mihai Adrian Ionescu, Anna Fontcuberta i Morral, Simon Robert Escobar Steinvall, Mahdi Zamani, Rajrupa Paul, Mirjana Dimitrievska, Valerio Piazza, Carlotta Gastaldi, Vanessa Conti

Scalable and sustainable photovoltaic technologies require low-cost and earth-abundant semiconducting materials. Zinc phosphide is purported to be an absorber material with optimal photovoltaic properties. Herein we report the electrical properties of Zn3P ...
