Halide Perovskite Photocatalysts for Clean Fuel Production and Organic Synthesis: Opportunities and Challenges

open access: yesAdvanced Materials, EarlyView.
This review provides the state‐of‐the‐art overview of halide perovskite‐based photocatalysts for hydrogen production from water and halogen acid solutions, CO2 reduction into value‐added chemicals, and organic chemical transformations. Different types of halide perovskite photocatalysts and their relative efficiencies for hydrogen generation and CO2 ...

Enhanced Kondo Effect in an Electron System Dynamically Coupled with Local Optical Phonon

open access: yes, 2007
We discuss Kondo behavior of a conduction electron system coupled with local optical phonon by analyzing the Anderson-Holstein model with the use of a numerical renormalization group (NRG) method.

Tailoring Robust Quantum Anomalous Hall Effect via Entropy‐Engineering

open access: yesAdvanced Materials, EarlyView.
Bandstructure renormalization, without (w/o) spin‐orbit interaction (SOI) (left) and with SOI (right), in the low‐energy Dirac bands of zero‐entropy (purple) and entropic (green) VCl3 monolayer (ML) with long‐range ordering (LRO). Abstract The development of quantum materials and the tailoring of their functional properties is of fundamental interest ...

The Significance of Corporations?EE(Environment Education) for Environmental Management and EE : Based on Qualitative Research on Collaborative EE in Japan

open access: yesThe Journal of The Korean Association of Geographic and Environmental Education, 2011
This paper has taken on the challenge of finding out the importance and possibility of corporations’ EE through a qualitative case study. For this purpose, the research is focused on the two collaborative EE programs initiated by corporations and NGOs. The main data research was compiled by conducting interviews, reviewing documents that related to the

On the energy efficiency-spectral efficiency trade-off over the MIMO rayleigh fading channel [PDF]

open access: yes, 2012
Along with spectral efficiency (SE), energy efficiency (EE) is becoming one of the key performance evaluation criteria for communication system. These two criteria, which are conflicting, can be linked through their trade-off. The EE-SE trade-off for the
