Complementary evaluation of structure stability of perovskite oxides using bond-valence and density-functional-theory calculations

open access: yesScience and Technology of Advanced Materials, 2018
Estimation of structure stability is an essential issue in materials design and synthesis. Global instability index (GII) based on bond-valence method is applied as a simple indication, while density functional theory calculation is adopted for accurate ...

21st century glaucoma care [PDF]

open access: yesEye, 2018
Glaucoma care has evolved dramatically over the past generation, with changes that have incorporated new technology and improved understanding of the disease process. A major need is to construct a useful definition of glaucomatous optic neuropathy that can be used to compare data across clinical research studies.

Fresh air in the 21st century? [PDF]

open access: yes, 2003
Ozone is an air quality problem today for much of the world's population. Regions can exceed the ozone air quality standards (AQS) through a combination of local emissions, meteorology favoring pollution episodes, and the clean-air baseline levels of ...

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents

open access: yesAdvanced Functional Materials, EarlyView.
Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...

‘Plenty of Disabled People Care’: Revealing Reciprocity and Interdependence in Disabled People’s Everyday Caregiving Practices

open access: yesScandinavian Journal of Disability Research
Care has historically been framed as something done to disabled people. Disability rights scholars have critiqued the loss of control and dependency associated with care; meanwhile, feminist care ethics has emphasised a relational conception of humans as

PARK7 DJ-1 protects against degeneration of nigral dopaminergic neurons in Parkinson’s disease rat model

open access: yesNeurobiology of Disease, 2006
DJ-1 has recently been shown to be responsible for onset of familial Parkinson’s disease (PD), PARK7. DJ-1 has been shown to play roles in transcriptional regulation and anti-oxidative stress, and loss of its function is thought to trigger onset of PD ...

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security

open access: yesAdvanced Materials, EarlyView.
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...
