Reducing the Pain Behind Opioid Prescribing in Primary Care.

Objective: To describe the efficacy of a comprehensive approach aimed at reducing opioid prescribing in an internal medicine resident clinic.

Design: Retrospective observational study.

Setting: Internal medicine primary care resident clinic at a large urban academic medical center.

Ion Write Microthermotics: Programing Thermal Metamaterials at the Microscale.

Considerable advances in manipulating heat flow in solids have been made through the innovation of artificial thermal structures such as thermal diodes, camouflages, and cloaks. Such thermal devices can be readily constructed only at the macroscale by mechanically assembling different materials with distinct values of thermal conductivity. Here, we extend these concepts to the microscale by demonstrating a monolithic material structure on which nearly arbitrary microscale thermal metamaterial patterns can be written and programmed.
