Impact toughness of Al-Li system alloys at low temperatures.
Journal of Japan Institute of Light Metals, 1987 Al-2.7%Li-1.2%Cu-0.8%Mg-0.1%Zr wrought alloys are heat treated to improve their impact toughness at lower temperatures, although a number of laminated cracks form in the vertical direction to the fracture surface. Low melting point elements, K and Na, are found on the fractured surface by Auger spectroscopy.

2D Co‐Assembly of Solid Acids Enables Stable Superprotonic Conduction Above 260°C
Advanced Functional Materials, EarlyView.A two‐dimensional co‐assembly strategy integrates antimony phosphate and phosphotungstic acid nanosheets into free‐standing inorganic lamellar membranes with confined acid–acid interfaces. The resulting interfacial hydrogen‐bond network enables anhydrous proton conductivity exceeding 0.1 S cm−1 at 260°C and supports stable high‐temperature fuel‐cell ...

Chitin‐Derived Carbon‐Metal Functional Materials
Advanced Functional Materials, EarlyView.Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Low-temperature magnetic properties of magnetite [PDF]
, 2000 Although several studies have recommended removal of secondary components of magnetic remanence by zero-field cycling from room temperature to a temperature much lower than the low temperature transition for magnetite (about 120 K), the method has not ...

The role of mental toughness and affect in academic success within a higher education setting [PDF]
‘Mental Toughness’ is recognised as an important component in academic success (Robinson 2013) represented by the psychological qualities that determine how challenges are effectively addressed in pressurised situations (Dewhurst et al. 2012).

Advanced Functional Materials, EarlyView.A mechanically programmable hydrogel for tissue engineering is developed by modulating the molecular threading density of poly(ethylene glycol) diacrylate‐β‐cyclodextrin (PEGDA‐β‐CD) polyrotaxane and combining it with β‐CD‐modified gelatin. The polyrotaxane‐guided transition from disordered pores to laminar microstructures enables precise tuning ...
