Stack engineering, an atomic-scale metamaterial strategy, enables the design of optical and electronic properties in van der Waals heterostructure devices. Here we reveal the optoelectronic effects of stacking-induced strong coupling between atomic m

In semiconductors, photo-excited charge carriers exist as a gas of electrons and holes, bound electron–hole pairs (excitons), biexcitons and trions1–4. At sufficiently high densities, the non-equilibrium system of electrons (e−) and holes (h+)

Tumours of the foot: A 10 years retrospective analysis

Autor: Vivek Ajit Singh, Vinesh Sandhu, Choo Tze Yong, Nor Faissal Yasin

Publikováno v: Journal of Orthopaedic Surgery, Vol 32 (2024)

Introduction The foot is a complex structure composed of several tissues, each of which can be the origin of the proliferation and development of the tumour. Most lesions about the foot are reactive or inflammatory, but some are true neoplasms. Metho

Publikováno v: Nano Letters. 15:6395-6399

Graphene's quantum Hall features are associated with a π Berry's phase due to its odd topological pseudospin winding number. In nearly aligned graphene-hexagonal BN heterostructures, the lattice and orientation mismatch produce a superlattice potent
