Efficient Electrocatalytic Conversion of CO2 to Pure Formic Acid Solutions via Strain‐Engineered Bismuth Nanosheets

Advanced Science, EarlyView.
Tensile‐strained bismuth nanosheets (TS‐BiNs) achieve a formate Faradaic efficiency of 92% at −1000 mA cm−2 and enable stable production of pure formic acid (HCOOH) in a solid‐state electrolyte reactor. Theoretical calculations reveal that the introduced strain lowers the energy barrier for *OCHO intermediate formation, fundamentally enhancing the ...

Scalable Human-Machine Point Cloud Compression

2024 Picture Coding Symposium (PCS)
Due to the limited computational capabilities of edge devices, deep learning inference can be quite expensive. One remedy is to compress and transmit point cloud data over the network for server-side processing. Unfortunately, this approach can be sensitive to network factors, including available bitrate.

Bamboo‐Like Whiskers‐Reinforced Bioceramics Accelerate Large Segmental Bone Regeneration via Dual Modulation of Type‐H Vessels and Osteoinduction

Advanced Science, EarlyView.
The graphical abstract image of bamboo‐like whisker‐reinforced Ca‐P bioceramics accelerating large segmental bone regeneration. ABSTRACT Regenerative repair of segmental bone defect remains a major clinical challenge. The conventional mental implants suffer from mechanical strength mismatch and long‐term foreign bodies presence.
