Crack Repair in Hydroxyapatite Bioceramics Using an Ultraviolet Ultrafast Laser

open access: yesAdvanced Materials Interfaces, EarlyView.
The study proposes an ultrafast ultraviolet laser approach to repair hidden tooth cracks, which has been preliminarily validated on HAP. Moreover, this technique aims to strengthen the native enamel structure rather than introducing a foreign filling material.

Relation Between Local Temperature Gradients and the Direction of Heat Flow in Quantum Driven Systems

open access: yes, 2011
We introduce thermometers to define the local temperature of an electronic system driven out-of-equilibrium by local ac fields. We discuss the behavior of the local temperature along the sample, showing that it exhibits spatial fluctuations following an ...

Observing the evaporation transition in vibro-fluidized granular matter [PDF]

open access: yes, 2006
By shaking a sand box the grains on the top start to jump giving the picture of evaporating a sand bulk, and a gaseous transition starts at the surface granular matter (GM) bed.

Radiative Cooling by Green(er) Solvents‐Upcycled Polyvinyl Chloride From Drug Blisters Waste

open access: yesAdvanced Optical Materials, EarlyView.
This study explores upcycling poly(vinyl chloride) (PVC) from used pharmaceutical blisters into sustainable radiative cooling materials. Using solvent separation and membrane fabrication, PVC was converted into white membranes paired with aluminum foil.

Local Symmetries and Order-Disorder Transitions in Small Macroscopic Wigner Islands

open access: yes, 2008
The influence of local order on the disordering scenario of small Wigner islands is discussed. A first disordering step is put in evidence by the time correlation functions and is linked to individual excitations resulting in configuration transitions ...

Chronoprints: Identifying Samples by Visualizing How They Change over Space and Time. [PDF]

open access: yes, 2019
The modern tools of chemistry excel at identifying a sample, but the cost, size, complexity, and power consumption of these instruments often preclude their use in resource-limited settings.

On–Off Switchable Micromotors for Use in Steerable Microvehicles

open access: yesAdvanced Robotics Research, EarlyView.
Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

Rapid deconvolution of low-resolution time-of-flight data using Bayesian inference [PDF]

open access: yes, 2019
The deconvolution of low-resolution time-of-flight data has numerous advantages, including the ability to extract additional information from the experimental data.
