A Finite Element Approach to Modelling Fractal Ultrasonic Transducers [PDF]
, 2014 Piezoelectric ultrasonic transducers usually employ composite structures to improve their transmission and reception sensitivities. The geometry of the composite is regular with one dominant length scale and, since these are resonant devices, this ...

Emergence of a Hexagonal Fe2S2 Single Layer Without a Bulk Counterpart via Phase Transformation
Advanced Functional Materials, EarlyView.Upon annealing, single‐layer Mackinawite iron sulfide transforms into a previously unknown hexagonal Fe2S2${\rm Fe}_2{\rm S}_2$ phase with β$\beta$‐CuI structure. STM, LEED, and first‐principles calculations identify the structure and show that electronic correlations and magnetic order are important for its stability.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics
Advanced Materials, EarlyView.“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.
