Key Trends and Insights in Smart Polymeric Skin Wearable Patches
Advanced Engineering Materials, EarlyView.Intelligent polymers, which respond to various physical and biological stimuli, are explored for the development of skin wearable patches in biomedical applications. Smart polymers, also known as intelligent or stimuli‐responsive polymers, play a crucial role in the development of advanced wearable patches due to their versatility and softness.

On the Generalization of the Concept of Impedance in Acoustics [PDF]
The Journal of the Acoustical Society of America, 1951 The conventional definitions of acoustical impedances so useful in the investigations of the properties of idealized systems with lumped parameters fail when applied indiscriminately to systems with distributed constants. In general, the present definitions are valid only when the specific impedance is constant on a wave front.

Heat Conduction Modulation in Incommensurate Twisted Stacking of Transition‐Metal Dichalcogenide
Advanced Functional Materials, EarlyView.The interlayer thermal conductance in twisted bilayer TMDs is initially investigated experimentally by the thermoreflectance method. The overlap of lattice vibrations within individual layers and the interlayer interactions, as elucidated through both Raman spectroscopy and molecular dynamics simulations, are demonstrated to be critical factors in ...

Advanced Functional Materials, EarlyView.EuSc₂Te₄, an antiferromagnetic semiconductor, exhibits a nonlinear Hall effect (NLHE) characterized by quadratic current–voltage behavior. Combined experimental and theoretical studies reveal that this NLHE is linked to its antiferromagnetism and involves contributions from the quantum metric.

Enhanced acoustic transmission through a slanted grating [PDF]
, 2015 It is known that an acoustic wave incident on an infinite array of aligned rectangular blocks of a different acoustic material exhibits total transmission if certain conditions are met [1] which relate the unique "intromission" angle of incidence with ...
