Comparison of the decomposition and crystallization behavior of Zr and Pd based bulk amorphous alloys

open access: yes, 2000
The best metallic glass formers known so far are Vit1 (and similar alloys with a slight variation in composition) and Pd40Cu30Ni10P20, having critical cooling rates of about 1 K/s and glass transition temperatures Tg of around 636 K and 582 K ...

Enhancing charge carrier extraction and energy band alignment in perovskite solar cells using interfacial passivation with polar organic molecules

open access: yesChemistry of Inorganic Materials
The wide utilization of perovskite material as an absorber layer in solar cells necessitates favorable alignment with the perovskite's conduction band, governed by FTO/TiO2 (SnO2).

Crystallization of metallic glasses under the influence of high density dc currents [PDF]

open access: yes, 2004
The effect of a dc current on the crystallization of Vit1A (Zr42.6Ti12.4Cu11.25Ni10Be23.75) and PCNP (Pd40Cu30Ni10P20) metallic glasses was investigated.

Chronic post-COVID neuropsychiatric symptoms (PCNPS) persisting beyond one year from being infected during the ‘Omicron wave’

open access: yes
Abstract The heterogeneity of chronic post-COVID neuropsychiatric symptoms (PCNPS), especially after infection by the Omicron strain, has not been adequately explored. Our pre-registered hypotheses are 1. chronic PCNPS in patients infected with SARS-CoV-2 over a year ago during the ‘Omicron wave’ showed a similar clustering pattern with

Polyacrylamide nanoparticles as a delivery system in photodynamic therapy [PDF]

open access: yes, 2011
Nanoparticles can be targeted towards, and accumulate in, tumor tissue by the enhanced permeability and retention effect, if sequestration by the reticuloendothelial system (RES) is avoided.
