Recent progresses on ion beam irradiation induced structure and performance modulation of two-dimensional materials.

Two-dimensional (2D) materials are receiving significant attention for both fundamental research and industrial applications due to their unparalleled properties and wide application potential. In this case, the controllable modulation of their structures and properties is essential for the realization and further expansion of their applications. Accordingly, ion beam irradiation techniques, with large scope to adjust parameters, high manufacturing resolution, and a series of advanced equipment being developed, have been demonstrated to have obvious advantages in manipulating the structure and performance of 2D materials.

Recent Research Progress in the Structure, Fabrication, and Application of MXene-Based Heterostructures.

Two-dimensional (2D) materials have received increasing attention in the scientific research community owing to their unique structure, which has endowed them with unparalleled properties and significant application potential. However, the expansion of the applications of an individual 2D material is often limited by some inherent drawbacks. Therefore, many researchers are now turning their attention to combine different 2D materials, making the so-called 2D heterostructures.

Fabrication of Nanopore in MoS-Graphene vdW Heterostructure by Ion Beam Irradiation and the Mechanical Performance.

Nanopore structure presents great application potential especially in the area of biosensing. The two-dimensional (2D) vdW heterostructure nanopore shows unique features, while research around its fabrication is very limited. This paper proposes for the first time the use of ion beam irradiation for creating nanopore structure in 2D vdW graphene-MoS heterostructures.

Recent Advances on Tuning the Interlayer Coupling and Properties in van der Waals Heterostructures.

2D van der Waals (vdW) heterostructures are receiving increasing research attention due to the theoretically amazing properties and unprecedented application potential. However, the as-synthesized heterostructures are generally underperforming due to the weak interlayer coupling, which inspires the researchers to find ways to modulate the interlayer coupling and properties, realizing the tailored performance for actual applications. There have been a lot of publications regarding the controllable regulation of the structures and properties of 2D vdW heterostructures in the past few years, while a review work summarizing the current advances is not yet available, though it is significant.

Solid-Pseudopapillary Neoplasm of the Pancreas: A 63-Case Analysis of Clinicopathologic and Immunohistochemical Features and Risk Factors of Malignancy.

Purpose: Solid-pseudopapillary neoplasm (SPN) of the pancreas, a rare tumor, has low malignant potential. However, some patients develop metastasis and recurrence after resection, with aggressive biological behaviors. This study aimed to explore the features and risk factors associated with the aggressive biological behaviors of SPNs.

Clinicopathological features and prognostic factors associated with gastroenteropancreatic mixed neuroendocrine non-neuroendocrine neoplasms in Chinese patients.

Background: The incidence of mixed neuroendocrine-non-neuroendocrine neoplasms (MiNEN) is low. To improve our understanding of this rare tumor type and optimally guide clinical treatment, associated risk factors, clinical manifestations, and prognosis must be explored.

Aim: To identify risk factors that influence the prognosis of patients with gastroenteropancreatic MiNEN (GEP-MiNEN).

COL1A1-PDGFB gene fusion in dermatofibrosarcoma protuberans: a useful diagnostic tool and clinicopathological analysis.

The PDGFB gene is found at 22q12.3-q13.1, and the COL1A1 gene is located at 17q21.

Sinonasalteratocarcinosarcoma: a report of two cases and clinicopathological analysis.

Sinonasalteratocarcinosarcoma (SNTCS) is a highly malignant and aggressive neoplasm which can quickly damage the local soft tissue, bone tissue, and invade orbital and intracranial tissues. It also can result in local lymph node and distant organ metastasis. The data from 2 cases of SNTCS from the First Affiliated Hospital of Bengbu Medical College (China), treated with radiotherapy and chemotherapy followed by cranio-facial resection, were analyzed since 2016.
