Critical Limitations in Cryogenic Laser Cooling of Solids: Symmetry‐Related Fluorescence Trapping and Condensation‐Induced Parasitic Heating

open access: yesAdvanced Science, EarlyView.
This study uncovers two overlooked bottlenecks in cryogenic laser cooling of solids: symmetry‐driven fluorescence trapping and water vapor condensation. We demonstrate that breaking sample symmetry enhances fluorescence escape, while condensation dominates parasitic heating below 135 K.

FIBER-REINFORCED CONCRETE WITH MINERAL FIBERS AND NANOSILICA

open access: yesInnovative technologies in science and education, 2015
Abstract The article presents the research results of mineral fiber use as a reinforcing component for concrete. The introduction of nanosilica to fiber cement compositions improves the corrosion resistance of the mineral fiber, due to the fact that nanosilica binds Ca(OH)2 during Portland cement hydration.

Redox Oligomer Assembling Hierarchical Reinforced Framework Cathodes for Ultra‐Stable High‐Performance Zinc‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
Redox phenoxoline‐benzoquinone oligomer has been designed as reinforced concrete framework like freestanding cathodes for high‐performance ZIBs. An optimal specific capacity of 339.5 mAh g−1 was contributed with exceptional retention of 87.5% after 65 000 cycles at 10 A g−1. Flexible energy storage is also demostrated.

The Investigation of Fiber Reinforcement Self-Compacting Concrete and Fiber Reinforcement Concrete

open access: yesJournal of Civil & Environmental Engineering, 2016
Precisely, researches have been done on Fiber Reinforcement Self-Compacting Concrete (FRSCC) which can divide into two different fields, material serviceability and mechanical rheology investigations. The mechanical aspect of FRSCC has been investigated to provide the constitutive models of shear and flexure capacity, tensile or compressive zone data ...
