Intermediated Surge Pricing [PDF]

open access: yesSSRN Electronic Journal, 2017
AbstractAlthough Uber and Lyft are known for their flexible “surge pricing,” they are surprisingly rigid in another way: each firm takes a constant percentage of passenger fare whether or not there is a surge. In this paper, I investigate the possible reasons for, and the impact of, this rigidity.

High‐Performance Low‐Emissivity Paints Enabled by N‐Doped Poly(benzodifurandione) (n‐PBDF) for Energy‐Efficient Buildings

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...

Active Thermal Field Integration for Marangoni‐Driven Salt Rejection and Water Collection

open access: yesAdvanced Functional Materials, EarlyView.
A thermal gradient fabric (TGF) evaporator with an auxiliary active thermal field can simultaneously increase evaporation rates and achieve long‐term salt rejection. The auxiliary active thermal field is well integrated with solar energy to construct moderate, extensive, and circulating Marangoni flow for salt rejection.

Ternary Transistors With Reconfigurable Polarities

open access: yesAdvanced Functional Materials, EarlyView.
Polarity‐reconfigurable ternary transistors are demonstrated using black phosphorus homojunction with asymmetric contacts and split‐gate structures. Suppression of majority carrier injection, while Fowler–Nordheim tunneling of low‐density minority carriers persists, enables a well‐defined intermediate state with improved on/off ratios.
