Gate Enhancing Charge‐Spin Conversion in Organic Chiral Field Effect Transistors
Advanced Science, EarlyView.Room‐temperature organic chiral multiferroic field effect transistors are demonstrated, enabling bidirectional control between spin and charge. Specifically, spin polarization affects the ferroelectric polarization, and ferroelectric polarization, in turn, can modulate spin polarization and spin‐dependent transport.

The Demand for Punishment [PDF]
While many experiments demonstrate that the actual behavior is different than predicted behavior, they have not shown that economic reasoning is necessarily incorrect.

The birds of the Bush Heritage, Cravens Peak Reserve [PDF]
, 2009 Bird communities were studied in two subregional areas of Cravens Peak, the Toko Plains and the Simpson-Strzelecki Dunefields, using the point counts method. A total of 42 2ha 20 minute surveys, 46 five-hundred metre radius area surveys and 170 5km drive

Exchange Length Tailored Magnetic Resonance for Broadband Absorption in FeCo‐Based Alloys
Advanced Science, EarlyView.To break the high‐frequency magnetic loss bottleneck in soft magnetic alloys, a magnetic exchange length (Lex)‐guided strategy is proposed. Cu doping increases Lex and intergranular coupling, which effectively reduces magnetic anisotropy and pushes the exchange resonance to 12.0 GHz.

What Norms Trigger Punishment [PDF]
Many experiments have demonstrated the power of norm enforcement-peer monitoring and punishment-to maintain, or even increase, contributions in social dilemma settings, but little is known about the underlying norms that monitors use to make punishment ...

Advanced Science, EarlyView.Gecko like multi directional high power magneto mechano electric energy harvester (MME EH) for self powered, hundred meter scale LoRa communication. Inspired by the symmetric and flexible limb motion of geckos, the biomimetic harvester enables coordinated bending twisting responses to weak, low frequency (50/60 Hz) stray magnetic fields from power ...
