Synergistic Interfacial Regulation by Nano‐TiO2 and Carboxylated Cellulose Nanofibers for Multiscale Surface Stabilization of Cementitious Composites

open access: yesAdvanced Materials Technologies, EarlyView.
Nano‐TiO2 and carboxylated cellulose nanofibers jointly regulate hydration‐product distribution in cementitious composites. Improved microstructural continuity and refined pore structure accompany enhanced strength and surface stability without a substantial increase in overall hydration.

A Fully Lithography‐Free Fabrication Strategy for Organic Electrochemical Transistors

open access: yesAdvanced Materials Technologies, EarlyView.
A fully lithography‐free fabrication strategy for organic electrochemical transistors (OECTs) is developed, eliminating the need for photolithography and other cleanroom‐based processes. By combining a laser‐cut polymer mask with a dual‐layer tape process, the proposed strategy enables simple and accessible fabrication, facilitating rapid OECT ...

A Human Bone Defect‐on‐a‐Chip Model for Studying Bone Regeneration

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a novel human bone defect‐on‐a‐chip (BDOC) model, aiming to recapitulate key processes during early bone healing, incorporating bone graft substitutes. Over 21 days, human mesenchymal stem/stromal cells (HMSCs) and human primary macrophages are co‐cultured in the BDOC together with calcium phosphate microparticles.

Functions of Na+/Ca2+ exchanger in rat embryonic neuronal cells

open access: yes, 2007
細胞膜上的鈉鈣交換蛋白可分為K+-dependent (NCKX)及K+-independent (NCX)兩種,對調控胞內鈣離子濃度([Ca2+]i) 的恆定,扮演重要的角色。根據細胞膜內外的鈉鈣電化學濃度梯度,鈉鈣交換蛋白有將Ca2+打出細胞外(正轉) 及將Ca2+送入細胞內(反轉) 兩種模式。當胞內鈉離子濃度提高以及細胞去極化時,會傾向於引發鈉鈣交換蛋白的反轉,但鈉鈣交換蛋白反轉對神經細胞活性的調控,目前並不清楚。在本實驗中我們以Ca2+影像以及RT-PCR的方法 ...

Molecular Appendix Adjusted Architectural Propagations of Red‐Light Controlled Macroscopic Photoactuating Performances

open access: yesAdvanced Robotics Research, EarlyView.
Amphiphilic chloroazobenzenes, bearing different amino acids as end groups alanine, phenylalanine, and valine, exhibit excellent photoisomerizations. Varying structures of three amino acid groups participate in supramolecular formations and therefore photoinduced morphological transformations via adjusting intermolecular interactions. These interaction
