Depth‐Customizable 3D Electrode Array for Recording Functional Connectivity in the Brain

open access: yesAdvanced Electronic Materials, EarlyView.
In this study, a depth‐adjustable, flexible 3D multi‐shank electrode array that produces precise neural recordings at various brain depths is developed. Integrating 2D flexible electrode arrays with a modular supporting board allowed the insertion depth to be easily adjusted without re‐fabrication.

Comparative Life Cycle Assessment of Perovskite Solar Cell Production: Mesoporous n‐i‐p Versus Inverted p‐i‐n Architectures

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This work assesses the environmental impacts associated with the production of perovskite solar cells (PSCs) with two different architectures, mesoporous n‐i‐p and inverted p‐i‐n, using the life cycle assessment methodology. Results indicate that producing mesoporous n‐i‐p PSCs has higher environmental impacts than producing inverted p‐i‐n PSCs, due to

Development Status and Future Prospects of Hydrogen Energy Technology: Production, Storage, and Cost Analysis

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Hydrogen is an energy carrier, produced from renewable and nonrenewable resources. It can be stored in a variety of materials and transported to distant locations. This article reviews progress in hydrogen technology by looking at environmental and economic impact, cost analysis, and policy support at government level as way forward for bringing it to ...

Primary Seat Belt Laws and Offsetting Behavior: Empirical Evidence from Individual Accident Data. [PDF]

open access: yes
According to the offsetting effect theory, since drivers wearing seat belts feel more secure, they tend to drive less carefully and may cause more accidents, including those involving pedestrians. Most previous studies have used only state-level accident
