Advances in Transparent Glass-Ceramic Phosphors for White Light-Emitting Diodes---A Review
Daqin Chen,Weidong Xiang,Xiaojuan Liang,Jiasong Zhong,Hua Yu,Mingye Ding,Hongwei Lu,Zhenguo Ji +7 more
TL;DR: In this paper, the authors provide an overview of recent progress in developing transparent inorganic glass-ceramics phosphors excitable by blue chip, as an alternative to conventional polymer-based phosphor converter, for construction of high-power white light-emitting diodes.
Thermal management of LEDs: Package to system
TL;DR: In this paper, the effect of chip packages on junction to board thermal resistance was compared for both SiC and Sapphire chips, and a conceptual LED illumination system was chosen and CFD models were created to determine the availability and limitations of passive air-cooling.
Journal ArticleDOI
Influence of cross-linkers on the cohesive and adhesive self-healing ability of polysulfide-based thermosets.
TL;DR: This work investigates the influence of the cross-linker and chain rigidity on the healing ability of thermoset rubbers containing disulfide bonds, finding that the thermal mending leading to full cohesive recovery can be achieved in 20-300 min at a modest healing temperature.

All-Inorganic Light Convertor Based on Phosphor-in-Glass Engineering for Next-Generation Modular High-Brightness White LEDs/LDs
Xuejie Zhang,Jinbo Yu,Jing Wang,Bingfu Lei,Yingliang Liu,Yujin Cho,Rong-Jun Xie,Hongwu Zhang,Yurong Li,Zifeng Tian,Yi Li,Qiang Su +11 more
TL;DR: In this paper, a robust light convertor that can simultaneously play key roles as a phosphor and an alternative encapsulating material via phosphor-in-glass (PiG) engineering is presented.

Highly Thermally Stable Single-Component White-Emitting Silicate Glass for Organic-Resin-Free White-Light-Emitting Diodes
TL;DR: The results demonstrate that the presented Ce(3+)/Tb( 3+)/Mn(2+) tridoped lithium-strontium-silicate glass may serve as a promising candidate for high-power WLEDs.

Autonomic healing of polymer composites
Scott R. White,Nancy R. Sottos,Philippe H. Geubelle,Jeffrey S. Moore,Jeffrey S. Moore,Michael R. Kessler,Suresh R. Sriram,Suresh R. Sriram,Eric Brown,S. Viswanathan +9 more
TL;DR: A structural polymeric material with the ability to autonomically heal cracks is reported, which incorporates a microencapsulated healing agent that is released upon crack intrusion and polymerization of the healing agent is triggered by contact with an embedded catalyst, bonding the crack faces.
Journal ArticleDOI
Self-healing and thermoreversible rubber from supramolecular assembly
TL;DR: The design and synthesis of molecules that associate together to form both chains and cross-links via hydrogen bonds and the system shows recoverable extensibility up to several hundred per cent and little creep under load are designed and synthesized.
Journal ArticleDOI
A Thermally Re-mendable Cross-Linked Polymeric Material
Xiangxu Chen,Matheus Adrianus Dam,Kanji Ono,Ajit Mal,Hongbin Shen,Steven Nutt,Kevin Sheran,Fred Wudl +7 more
TL;DR: A transparent organic polymeric material that can repeatedly mend or “re-mend” itself under mild conditions and is a tough solid at room temperature and below with mechanical properties equaling those of commercial epoxy resins.
