“…This has been demonstrated in schemes for thermomechanical writing that use a combination of heat and force to press a heated, sharp tip into a polymer surface, creating a plastic deformation. [2,6,9,10] The heated tip causes very local heating of the polymer material above its softening temperature, which effectively acts as the switch to turn on the writing process. [11] Although linear polymers exhibit such switching behavior above and below the glass-transition temperature (T g ), [6] they do not satisfy the other device requirements, especially stability to the repeated motion of surface scanning during imaging (e.g., reading).…”

Reversibly crosslinked polymer films have properties that are beneficial to scanned‐probe data storage and lithographic applications that use thermomechanical nanoindentation as a write or expose mechanism. The novel polymer under study contains linkages based on thermally reversible Diels–Alder crosslinking. Thermomechanical properties on the nanometer scale are analyzed by indentation experiments on polymer thin films using heated tips. The underlying indentation mechanism is studied at varying tip temperatures and indentation times, revealing Arrhenius kinetics. This is in contrast to the Williams–Landau–Ferry kinetics usually observed for polymer systems. The discrepancy is explained by the reversible crosslinking incorporated into the structure of the polymer that allows switching between two different states: a rigid, highly crosslinked, low‐temperature state, and a deformable, fragmented, high‐temperature state. An individual indentation volume of less than 10–20 L (10 000 molecule pairs) is estimated. These kinetics experiments demonstrate that a chemical reaction of only a few thousand molecules can be transduced into a mechanically measurable action. The ability to cycle between two sets of properties in these materials opens up new perspectives in lithography and data storage. Examples of data storage with densities up to 1 Tb in.–2 and maskless lithography with resolution below 20 nm are demonstrated at writing times of 10 μs per bit/pixel.

“…Tapering can enhance the potential of the optical fibers as sensors [5]. Probe taper angle is an important factor which determines the probe characteristics [6]. For applications in nano-optics, tapered optical fibers should exhibit short and robust taper region with a large opening angle at the apex [1].…”

The objective of this experiment is to study the effect of taper angle of the optical fiber microprobe in power collection. Optical fiber microprobes with taper angle from 10° to 23° were fabricated using the automatic fusion splicer by applying one-sided pulling and electric arc heating technique. It was found that the maximum power detected by a small taper angle probe was only -34.22dBm. The highest optical power collected by the optical fiber microprobe in this study was -25.01dBm with taper angle of 22.9°. Large taper angle probe receives more light at the tip which increases the sensitivity of the probe.

In recent years, tissue engineering has emerged as a cutting‐edge approach for the treatment of spinal cord injury (SCI) owing to its remarkable capabilities. It can create living tissues with robust vitality, achieve maximal tissue repair with minimal cell usage, and facilitate seamless reconstruction with unmatched plasticity, all while addressing immune rejection issues. Among these advancements, one‐dimensional (1D) materials have garnered significant attention. Their morphology closely resembles the extracellular matrix environment, thereby fostering the elongation of dendrites and axons on neurons and greatly enhancing the prospects for SCI repair. With a keen focus on the latest advancements in the application of 1D nanomaterials in nerve tissue engineering for spinal nerve repair, this review delves into several key aspects. Firstly, it explores the “bottom‐up” approach to synthesizing 1D nanomaterials. Secondly, it examines the mechanisms by which these nanomaterials influence neural tissue engineering. Thirdly, it presents various cutting‐edge strategies aimed at optimizing the morphology and performance of 1D materials, thereby enhancing the efficiency of nerve tissue injury repair. Lastly, it discusses the current challenges and future prospects facing this fascinating field. We aspire that this comprehensive review will provide a profound understanding of the development of 1D materials in neural tissue engineering and inspire a wider audience with its potential.
