Enhancement of Fracture Toughness of NiTi Alloy by Controlling Grain Size Gradient.
Nanomaterials (Basel)
January 2025
School of Civil Engineering, Wuhan University, Wuhan 430072, China.
Fracture toughness is a critical indicator for the application of NiTi alloys in medical fields. We propose to enhance the fracture toughness of NiTi alloys by controlling the spatial grain size (GS) gradient. Utilizing rolling processes and heat treatment technology, three categories of NiTi alloys with distinct spatial GS distributions were fabricated and subsequently examined through multi-field synchronous fracture tests.

African swine fever (ASF) is an acute hemorrhagic disease in pigs caused by the African swine fever virus (ASFV), which has a high mortality rate and brought great damage to global pig farming industry. At present, there is no effective treatment or vaccine to combat ASFV infection, so early detection of ASFV has become particularly important. Therefore, the PDMS/chitosan/MPMs composite film was proposed to detect ASFV P72.

The emergence of very high NMR magnetic fields will certainly encourage the study of larger biological systems with their dynamics and interactions. NMR spin relaxation allows probing the dynamical properties of proteins where the N longitudinal () and transverse () relaxation rates in addition to the H-N heteronuclear NOE describe the ps-ns time scale. Their analytical representation involves the chemical shift anisotropy (CSA) effect that represents the major contribution at a very high magnetic field above 18.

Federal Center of Neurosurgery, Novosibirsk, Russia.
Objective: To analyze the postoperative outcomes in patients with craniovertebral meningiomas with preoperative justification of surgical approach depending on tumor localization.
Material And Methods: We examined 36 patients with craniovertebral meningiomas. The Karnofsky, Frankel and cranial nerve dysfunction scales were used to assess functional status of patients.
