Thermoelectric properties through a wire composed of isoprene molecules

AIP Advances, 2020
In this work, we study the electrical and thermoelectric properties through carbon bonds acting as nanowires derived from linear unsaturated organic molecules with a π conjugated system composed of isoprene molecules (NWIM) linked to leads.

Enhancing Sensitivity across Scales with Highly Sensitive Hall Effect‐Based Auxetic Tactile Sensors

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Herein, a tactile sensor based on hall‐effect sensors with an auxetic structure, called Hall effect‐based auxetic tactile sensor (HEATS), is proposed. The change in magnetism resulting from the deformation of the auxetic structure is utilized for sensing.

ALGORITHMIC METHOD FOR ENERGY BANDS STRUCTURE SIMULATION IN CUBIC LATTICES

Momento, 2014
In this work a model for studying energy band structures was implemented. The model is based on the finite differences method, using a 3D array. Initially, the unit cell is gridded with h as step, in order to divide the lattice in smaller parts.

The role of Tris(2-carboxyethyl)phosphine reducing agent in the controlled formation of α,ω-Alkanedithiols Monolayers on Au(111) with monocoordinated and bicoordinated configurations [PDF]

, 2016
The addition of the reducing agent tris(2-carboxyethyl) phosphine (TCEP) during the formation of α,ω-alkanedithiols monolayers on Au(111) using the immersion method produces the assembly of monolayers with bicoordinated molecules (both S-terminal groups ...

Investigation of the Optical and Morphological Properties of PS/POMA Blends Hybridized With Erbium Oxide (Er2O3)

Journal of Applied Polymer Science, EarlyView.
ABSTRACT Polymeric blends (PB) represent a rapid and cost‐effective strategy for the development of materials with tailored properties. In this study, blends of polystyrene (PS) and poly(o‐methoxyaniline) (POMA) containing 7.5 wt/wt% of POMA were prepared and hybridized with erbium oxide (Er2O3) at concentrations of 0.5, 1.0, and 3.0 wt/wt%.

Effect of Ramped Oxygen Flow During Magnetron Sputtering on the Structural, Optical, and Photoelectrochemical Properties of WO3‐x Thin Films

Advanced Physics Research, EarlyView.
A compositionally graded WO3‐x thin film was engineered through a controlled linear increase of oxygen flow during reactive magnetron sputtering. This deposition strategy yields a gradual transition from an oxygen‐deficient, conductive bottom layer to a more stoichiometric and crystalline surface layer, forming an intrinsic gradient homojunction.

Programming the Optoelectronic Properties of Atomically Precise Gold Nanoclusters Using the Conformational Landscape of Intrinsically Disordered Proteins

Chemistry – A European Journal, EarlyView.
ABSTRACT The rational design of hybrid nanomaterials with precisely controlled properties remains a central challenge in materials science. While atomically precise gold nanoclusters (Au‐NCs) offer molecule‐like control over a metallic core, tuning their optoelectronic behavior via surface engineering is often empirically driven.
