Gellan Gum Fluid Gel System for Controlled‐Delivery of Cytokine‐Licensed MSC‐EVs to Enhance Corneal Repair in Limbal Stem Cell Deficiency

open access: yesAdvanced Healthcare Materials, EarlyView.
Gellan gum fluid gel (FG) enables controlled ocular delivery of mesenchymal stromal cell (MSC)‐derived extracellular vesicles (EV). Its shear‐thinning, solid‐liquid‐solid rheology ensures prolonged ocular retention. Sustained MSC‐EV release (∼18% in 6 hrs) supports effective EV ocular delivery.

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

open access: yesAdvanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

COFs on MOFs: Layer‐by‐Layer Synthesis of MOF@COF Nanoparticles with Synergistic Adsorption

open access: yesAdvanced Materials, EarlyView.
A layer‐by‐layer strategy enables the growth of crystalline covalent organic framework (COF) shells on metal–organic framework nanoparticles, creating core–shell structures with tunable porosity. Ordered interstitial mesopores are formed during shell growth, which are connected with the COF's intrinsic micropores, thereby enhancing water sorption. This

On full-view area coverage with camera rotation in wireless camera sensor networks

open access: yes, 2017
碩士如何有效地區域覆蓋在攝影機感測網路中一直是十分重要的議題,不過大部分文獻都只考慮到如何覆蓋,卻沒有考慮到攝影機擺放的方向,使得即使攝影機覆蓋住目標物,也無法保證辨識目標物的身分,喪失了攝影機可以取得目標物影像資訊的特性。因此,本篇論文提出了區域覆蓋影像辨識(Full-View Area Coverage, FVAC)機制以有效地區域覆蓋並辨識目標物的影像。在FVAC中,我們會先以有效角的大小決定安全區域與不安全區域的範圍,再將攝影機感測器依照四方形方格的方式進行先決式的部署 ...
