Article Synopsis
- Tantalum carbides (TaC) exhibit unusual hardness behavior where they initially harden with some carbon loss, then soften with further decarburization, a phenomenon seen since 1963 but not fully understood.
- This study identifies a shift in the slip system for TaC from {111} to {110} as carbon content decreases, contrasting with titanium carbide (TiC), which does not show this transition.
- Experimental findings reveal a hardness peak in bulk TaC samples at varying carbon levels, while thin films do not show this peak due to diminished dislocation plasticity in nanocrystalline structures.
Pore engineering is commonly used to alter the properties of metal-organic frameworks. This is achieved by incorporating different linker molecules () into the structure, generating isoreticular frameworks. CPO-27, also named MOF-74, is a prototypical material for this approach, offering the potential to modify the size of its one-dimensional pore channels and the hydrophobicity of pore walls using various linker ligands during synthesis.

J Phys Condens Matter
September 2024
In this paper we investigate the interconnection between vacancy-ordered phases and vacancy self-diffusion. Here, we investigate three ordered phases on a square lattice with energetics defined by two separate Hamiltonians. In the first case we used a classical antiferromagnetic Ising model Hamiltonian in order to generate a 'checkerboard' type ordered structure.

- Verrucous carcinoma (VC) is a rare and low-grade type of squamous cell carcinoma that typically appears as a slow-growing, wart-like growth on the soles of the feet, particularly in areas of weight bearing.
- A patient had a 20-year history of a potentially misdiagnosed, ulcerated verrucous plaque on their foot that was initially treated as a common wart but was later found to be invasive verrucous carcinoma.
- Accurate diagnosis is crucial since these carcinomas can mimic benign growths, and Mohs micrographic surgery is recommended to ensure proper removal while preserving healthy tissue; delays in treatment can lead to more severe interventions like dissection or amputation.
