Product innovation when consumers have switching costs
Economists have long recognized that in free markets, incentives to innovate will be diluted unless some factors grant innovators with a temporary monopoly. Patenting is the most cited factor in the economic literature.

Minimally Invasive Delivery of Optical Nanosensors Using Injectable Hydrogels
Advanced Materials Interfaces, EarlyView.Injectable peptide hydrogels offer a minimally invasive delivery platform for single‐walled carbon nanotube (SWCNT)‐based near‐infrared fluorescent sensors, enabling real‐time measurement of drug concentrations. Encapsulated SWCNTs show a dose‐dependent fluorescence response across physiologically relevant concentrations and retain their fluorescence ...

Information Sharing and Information Acqusition in Credit Markets
Since information asymmetries have been identified as an important source of bank profits, it may seem that the establishment of information sharing arrangements such as credit registers and bureaus will lead to lower investment in acquiring information.

Facet‐Specific PbS Quantum Dot Passivation Using Halide Perovskites for SWIR Photodetectors
Advanced Materials Interfaces, EarlyView.PbS quantum dots (QDs) are emerging as powerful short‐wave infrared photodetectors, yet the passivation mechanism of large QDs by perovskites ‐ critical for their stability ‐ remains unexplained. Here, we unveil the ligand structure of CH3NH3PbI3 (MAPI)‐passivated 4‐nm PbS QDs using FTIR, XPS, SEM, NMR, and DFT.

Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications
Advanced Materials Technologies, EarlyView.A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.
