Efficiency versus Robustness of Markets - Why improving market efficiency should not be the only objective of market regulation [PDF]
The efficiency of capital markets has been questioned almost as long as the efficient market hypothesis had been worked out. Numerous critics have been formulated against this hypothesis, questioning notably the behavioural assumptions underlying the ...

Chemically Doped Conductive Polymers for Wearable Health Monitoring
Advanced Materials Technologies, EarlyView.Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.

Optofluidic Raman Analysis and Capacity Recovery in Li‐ion Cells
Advanced Materials Technologies, EarlyView.Operando Raman spectroscopy is used to monitor the degradation of commercial Li‐ion cells. Using a microfluidic access port, small amounts of electrolyte are sampled into a hollow‐core optical fibre, where fibre‐enhanced Raman analysis reveals Li+ solvation changes and solvent evolution.
