Fotoluminescência em amostras policristalinas de galato de magnésio dopado com Ni2+ Photoluminescence of polycrystalline samples of magnesium gallate doped with Ni2+

open access: yesCerâmica, 2006
São apresentados resultados de fotoluminescência do MgGa2O4:Ni2+ nas temperaturas ambiente e de nitrogênio líquido. As bandas observadas são atribuídas às transições proibidas por spin, ¹T2 (¹D) -> ³T2 (³F) e ¹T2 (¹D) -> ³T1 (³F), no visível e no ...

Monte Carlo modeling of radiation dose from radiation therapy with superficial x‐rays

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Introduction Superficial x‐rays (50–100 kVp) are used for treating non‐melanoma skin cancer and intraoperative radiation therapy (IORT). At these energies, the photoelectric effect significantly increases absorbed dose to bone compared to soft tissue.

Development of a drug delivering round window niche implant for cochlear pharmacotherapy

open access: yesDrug Delivery
Background There exists an unfulfilled requirement for effective cochlear pharmacotherapy. Controlled local drug delivery could lead to effective bioavailability. The round window niche (RWN), a cavity in the middle ear, is connected to the cochlea via a

Photonic-Spin governed absorption in a mu-near-zero subwavelength gyromagnetic cylinder [PDF]

open access: yesarXiv
Realizing non-reciprocal scattering and absorption from subwavelength elements has several applications across the electromagnetic frequency spectrum. Here we show that gyromagnetic cylindrical rods with subwavelength dimensions exhibit strong absorption with diminished scattering in a narrow frequency band for an incident plane wave.
