Advanced Functional Materials, EarlyView.Moiré band engineering in graphene/hexagonal boron nitride–based superlattices unlocks van Hove singularities (VHSs) for terahertz (THz) optoelectronics. Tuning the Fermi level near these singularities, associated with secondary neutrality points (SNPs), enhances the photothermoelectric response.

Asymmetric price transmission in the commercialization of rice in Brazil
Italian Review of Agricultural Economics, 2020 This paper aims to investigate the presence of price transfer asymmetry (APT) in the rice production chain in Rio Grande do Sul incorporating in the analysis the effects of public policy interventions, specifically the agricultural minimum prices. The results indicate the occurrence of positive APT among all relations analyzed (contemporaneous, lagged ...

Asymmetric price transmission effect of corn on hog: evidence from China
Agricultural Economics (AGRICECON), 2018 In this study, we used monthly corn price and hog price data from January 2000 to June 2015 to conduct an empirical analysis based on a smooth transition regression (STR) model. The analysis confirms and explains the asymmetric transmission mechanism and

Advanced Functional Materials, EarlyView.InSb, a narrow‐bandgap semiconductor with high carrier mobility, is promising for thermoelectric energy conversion but suffers from high lattice thermal conductivity and strong bipolar conduction. Here, in situ interface engineering using Co2O3 nanoprecursors forms hierarchical CoSbx/In2O3/CoSb3 heterostructures that enhance phonon scattering and ...
