Spherical and Aspherical Lenses for Boosting the Performance of Terahertz Imaging Systems

Advanced Photonics Research, EarlyView.
This study investigates the enhancement of terahertz (THz) detection through the terajet effect using mesoscale dielectric lenses of various geometries. Spherical, aspherical, and cubic polytetrafluoroethylene lenses are evaluated at 0.15 and 0.3 THz, demonstrating significant improvements in responsivity and noise reduction.

Synthesis of spirolactones from carbonyls via carboborylation of N‐sulfonylhydrazones with alkoxycarbonylalkylboronic acids

Advanced Synthesis &Catalysis, Accepted Article.
A straightforward synthesis of spirolactones from carbonyls via N‐tosylhydrazones is described. The process consist in the reaction between the N‐tosylhydrazone and ethoxycarbonylethylboronic acid or ethoxycarbonylpropylboronic acid, leading to spiro γ‐butyrolactones or δ‐valerolactones respectively. The transformation takes place by carboborylation of

Adaptive Catalytic Nanointerfaces for Controlled Hydrogen Evolution: an in Situ Electrochemical Approach

Advanced Science, EarlyView.
The ability to switch the HER activity of precious metals at will through a reconfigurable step‐edge/nanoparticle interface, using sulfur as an inorganic mediator, is demonstrated for the first time. This methodology addresses the durability issue of highly catalytic precious metals, which are typically single‐use, thereby extending their lifespan ...

Encoding Specific 3D Polyhedral Complexes Using 3D Binary Images [PDF]

, 2016
We build upon the work developed in [4] in which we presented a method to “locally repair” the cubical complex Q(I) associated to a 3D binary image I, to obtain a “well-composed” polyhedral complex P(I), homotopy equivalent to Q(I).

Real‐Time Force Monitoring of Electrically Stimulated 3D‐Bioengineered Muscle Bioactuators Using Organic Sensors with Tunable Sensitivity

Advanced Intelligent Systems, EarlyView.
The integration of sensing elements in bioengineered actuators is key to obtain real‐time information about their performance and further control/automation. By coupling flexible organic field‐effect transistor to a skeletal muscle actuator we demonstrate the feasibility to record in real‐time its contractile behavior when stimulated by electrical ...
