Residue-Free Fabrication of van der Waals Heterostructures of Two-Dimensional Materials
0 Views •
2025
This study presents a residue-free fabrication methodology for producing single flakes of two-dimensional materials and assembling them into complex heterostructures using only van der Waals interactions. The technique eliminates the need for external substances and specific experimental conditions, enabling complex heterostructure assemblies through bottom-up, top-down, and modular stacking processes.

This methodology allows applying a dental appliance on any specimen at any angle with standardized force and stability. This approach might be extensively used in health sciences to standardize the impacts of dental equipment with hand-holding elements such as micromotors, turbines, and ultrasonic scalers on varied surfaces.

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University In the back of everyone's eye is a small piece of neural tissue called the retina. The retina has photosensitive cells that respond to stimulation by light. The responses of these cells are sent into the brain through the optic nerve, a bundle of neural fibers. In each retina there is a place somewhere in the periphery where the outputs from retinal cells collect and the bundled optic nerve exits to the brain. At that location,...

Residual Stresses

Residual stresses reside in a structure even after removing the original stress inducer. This phenomenon often arises from varied plastic deformations across different parts of a structure. Consider a rod stretched beyond its yield point. It will not regain its original length due to permanent deformation. Even after load removal, the rod does not entirely lose stress because of uneven plastic deformations, resulting in residual stresses. The computation of these stresses in structures is...

Residual Plots

A residual plot is a statistical representation of data used to analyze correlation and regression results. It helps verify the requirements for drawing specific conclusions about correlation and regression. To obtain the residual plot, first, the residual for each data value is calculated, which is simply the vertical distance between the observed and the predicted value obtained from the regression equation. When the residual values are plotted against the variable x, it is called a residual...
FAQs
Root canal instruments cannot contact every surface of a treated canal. Irregularities, undercuts, and accessory canals can therefore shelter remnants of gutta-percha or sealer during placement, shaping, revision, or removal. The location of these spaces helps explain why material may persist even when the main canal has been instrumented and filled.
Location determines how readily clinicians can identify, assess, or address the remnant. Material within an irregularity, undercut, or accessory canal may be difficult to reach, while its relationship to the treated site provides context during evaluation. Mapping where remnants remain supports more informed decisions about removal, preservation, and infection control.
The presence and condition of remnants contribute to evaluating how completely a treated site was managed. When symptoms continue, clinicians consider these findings alongside examination and imaging rather than interpreting the material in isolation. This assessment helps guide infection-control decisions and supports consideration of the tooth’s longer-term prognosis.
Clinical examination and imaging provide complementary information about remaining material. These methods help clinicians identify remnants and assess their location, particularly when a tooth requires retreatment or symptoms persist. The resulting information can clarify whether material occupies a difficult-to-reach area and can inform subsequent management of the treated site.
During retreatment, clinicians use examination and imaging to determine where remnants are located and how they relate to the previously treated canal system. They then weigh whether removal is appropriate or whether preservation is preferable, while also considering infection control. This process connects the physical finding with practical treatment decisions rather than treating every remnant identically.
Removal is not the only possible response to a remnant. Clinicians consider its location and condition, the findings from clinical examination and imaging, and whether symptoms continue. If the material is difficult to access or its removal is not judged necessary, preservation may be considered while treatment planning remains focused on infection control and prognosis.
