Interconnected Porous Hydrogels with Tunable Anisotropy Through Aqueous Emulsion Bioprinting

Advanced Functional Materials, EarlyView.
A 3D bioprintable microporous bioink is developed using an aqueous two‐phase system (ATPS) composed of extracellular matrix (ECM) mimetic biopolymers. The ATPS bioink enables the fabrication of interconnected porous architectures with up to 70% porosity, supporting long‐term cell viability and 3D cell alignment, enabling a simultaneous generation of ...

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

Advanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

Understanding and Tuning Mobile Interfaces in Ferroelectric Hf0.5Zr0.5O2 Thin Films in Relation to Microstructure

Advanced Functional Materials, EarlyView.
Ferroelectricity in thin HfO2‐based films offers great possibilities for next‐generation neuromorphic memory devices. There, the response to subcoercive voltage signals is driven by the movement of mobile interfaces and their interaction with crystal defects – a yet rather unexplored aspect, which we shed light on and gain new insights into the complex

Efficient NiOx Hole Transport Layers Enabled by Multifunctional MXenes for High‐Performance Tin‐Lead Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
An efficient NiOx HTL is successfully prepared by introducing MXene as an additive without further surface modification to fabricate high‐performance FASn0.5Pb0.5I3 perovskite solar cells. The introduction of MXene contributes to improved conductivity of NiOx, better aligned at NiOx/perovskite interfaces, and enhanced quality of perovskite films ...

Frozen section — frozen attitudes

Journal of Surgical Oncology, 1976
AbstractThe elimination of frozen section diagnosis will free the patient from one of the great fears of the current treatment of breast cancer ‐ subjecting herself to biopsy without knowing what the outcome will be. It will free the surgeon from the rigid sequence of frozen section followed by mastectomy and allow him to begin to rationally assign ...

Cooperative Frozen Section Surgery

The Journal of Dermatologic Surgery and Oncology, 1987
Abstract Utilization of the office setting for frozen section evaluation of tumor removal in the treatment of skin cancer is of considerable value. The impact of such surgery includes (1) enhanced quality of surgery by reducing the possibility of incomplete removal of tumor, (2) decreased financial cost to the patient when compared to hospital ...

Preparation of Frozen Sections

Dermatologic Surgery, 2004
For dermatologists the preparation of frozen sections means micrographic surgery. The preparation of frozen sections is meant to be rapid, but has multiple, discrete steps that demand attention to detail.The objective was to summarize both the proven and the cutting-edge techniques of frozen section preparation.Reports from the medical literature were ...

Thyroid Frozen Section

American Journal of Surgical Pathology, 2013
A total of 704 cases of thyroid cancer were retrospectively reviewed (2005 to 2011) to assess the contribution of frozen section (FS) to preoperative fine-needle aspiration (FNA). There were 613 papillary carcinomas (87.1%), of which 237 were

Frozen Sections

JAMA, 1984
THE THEORY behind using the frozen section technique for quick tissue diagnosis is quite simple: while the patient is kept under continual anesthesia, the frozen section can rapidly provide information to the operating surgeon to help "make a therapeutic decision." 1 Not always, however, is this procedure used in a proper manner.
