Ultrastable glasses (mostly prepared from the vapor phase under optimized deposition
conditions) represent a unique class of materials with low enthalpies and high kinetic …

Two challenging scientific disciplines, ie, the physics of glasses [Anderson, Science 267,
1615 (1995); Kennedy and Norman, Science 309, 75 (2005)] and interface chemistry …

Waterborne polyurethane has drawn extensive attention due to its environmental
friendliness and is widely used in many areas. However, it is still a great challenge to …

Surfaces mediate the formation of stable glasses (SGs) upon physical vapor deposition
(PVD) for a wide range of glass formers. The thermodynamic and kinetic stability of SGs and …

Surface diffusion is vastly faster than bulk diffusion in some glasses, but only moderately
enhanced in others. We show that this variation is closely linked to bulk fragility, a common …

Recently, a putative phase transition has been discovered in metallic glasses that could lead
to two distinct amorphous states. This phenomenon, known as polyamorphism, has …

We present a recyclable perovskite–graphene heterostructure that demonstrates ultrahigh X-
ray detection sensitivities over 108 μC/Gyair· cm2 for medical imaging applications. The high …

When a liquid is cooled, progress down the energy landscape is arrested near the glass
transition temperature T g. In principle, lower energy states can be accessed by waiting for …

When aged below the glass transition temperature, T g, the density of a glass cannot exceed
that of the metastable supercooled liquid (SCL) state, unless crystals are nucleated. The …

The recent surge in tandem solar cells and indoor photovoltaics has renewed interest in
selenium (Se), the world's first photovoltaic material, due to its intrinsic wide bandgap of≈ …
