Advances in Thermoelectric Thin Films Grown by Atomic Layer Deposition: A Critical Review of Performance and Challenges

open access: yesAdvanced Energy Materials, EarlyView.
This review highlights the use of atomic layer deposition (ALD) for fabricating thermoelectric thin films with atomic‐scale control. Four material classes—chalcogenides, doped oxides, ternary oxides, and multilayered structures—are compared in terms of growth dynamics, structure–property relationships, and thermoelectric performance. The precise tuning

Using FPGA for visuo-motor control with a silicon retina and a humanoid robot [PDF]

open access: yes, 2007
The address-event representation (AER) is a neuromorphic communication protocol for transferring asynchronous events between VLSI chips. The event information is transferred using a high speed digital parallel bus.

Thermoelectric Performance and Morphological Stability of Thin Titania: Carbon Black Hybrid Films Against Humidity and Light Irradiation

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Nanostructured titania:carbon black hybrid films, fabricated via water‐based slot‐die coating, show stable thermoelectric performance under light irradiation but degrade under high humidity. Operando grazing incidence small‐angle X‐ray scattering reveals humidity‐induced morphological changes correlating with reduced Seebeck coefficients.

Growth of lead tin telluride crystals in gels [PDF]

open access: yes
Improved gels and several geometries were investigated for use in growing crystals. The use of lead sulfide test crystals proved workable, but it was impossible to obtain and maintain a sufficiently concentrated telluride ion solution to successfully ...

First‐Principles Investigation of the Thermoelectric Behavior of the Orthorhombic Cadmium Stannate (Cd2SnO4)

open access: yesAdvanced Physics Research, EarlyView.
Cd2SnO4 exhibits excellent thermoelectric properties with a high Seebeck coefficient, power factor, and figure of merit, surpassing Bi2Te3. It shows both positive and negative Seebeck coefficient values, making it suitable for diverse applications. Its high electrical conductivity and low thermal conductivity enhance efficiency, while its negative Hall

Synthesis and Characterization of π‐Extended Azulenes via Nucleophilic Substitution and Intramolecular Cyclization of 5‐Alkynyl‐6‐Fluoroazulenes

open access: yesChemistryEurope, EarlyView.
A modular synthetic approach enables the preparation of azulene‐fused heterocycles via nucleophilic aromatic substitution followed by intramolecular cyclization of alkynyl fluoroazulenes. The method allows the incorporation of various heteroatoms (N, O, S, Se, and Te), leading to structurally diverse heteroannulated azulenes.

Insight Into the Failure Mechanism of Conversion‐Alloy Anode Materials in Potassium‐Ion Batteries: A Case Study of Bi2Te3

open access: yesCarbon Energy, EarlyView.
Through combining electrochemical profiles with multi‐scale microscopies, spectroscopy, and theoretical calculations, the failure processes and mechanisms of Bi2Te3 are identified into two stages: (1) the shuttle effect, dominating the first stage, results in the rapid capacity fading in the first several cycles and (2) the SEI accumulation, dominating

AER-based robotic closed-loop control system [PDF]

open access: yes, 2008
Address-Event-Representation (AER) is an asynchronous protocol for transferring the information of spiking neuro-inspired systems. Actually AER systems are able to see, to ear, to process information, and to learn.
