Structural and electrochemical analysis of CIGS: Cr crystalline nanopowders and thin films deposited onto ITO substrates
(MDPI, 2021-04-23)
A new approach for the synthesis of nanopowders and thin films of CuInGaSe2 (CIGS) chalcopyrite material doped with different amounts of Cr is presented. The chalcopyrite material CuInxGa1 − xSe2 was doped using Cr to form ...
Quantification of charge carriers and acetate diffusion lengths in intermittent electro-active biofilms using Electrochemical Impedance Spectroscopy
(Elsevier, 2023-10-17)
Intermittent anode potential regimes have been used to increase the concentration of charge carriers in electro-active biofilms (EABfs). Even though this increased number of carriers is typically correlated to higher current ...
Redox-active hierarchical assemblies of hybrid polyoxometalate nanostructures at carbon surfaces
(Royal Society of Chemistry, 2022-03-03)
The self-assembly of hierarchical nanostructures on surfaces is a promising strategy for the development of a wide range of new technologies, such as energy-storage devices and sensors. In this work we show that amphiphilic, ...
Single-pixel imaging through non-homogeneous turbid media with adaptive illumination
(Optica Publishing Group, 2024-03-29)
The presence of scattering media limits the quality of images obtained by optical systems. Single-pixel imaging techniques based on structured illumination are highly tolerant to the presence of scattering between the ...
Improvement of optical and conductivity properties of SnS2 via Cr doping for photovoltaic applications
(Elsevier, 2023-10-15)
Tin disulfide doped with chromium (Sn1−xCrxS2) powders with different molar ratios (x = 0, 2, 4, 6, and 10 at%) were synthesized using a low-cost hydrothermal technique. The prepared samples were characterized by X-ray ...
Unprecedented solar water splitting of dendritic nanostructured Bi2O3 films by combined oxygen vacancy formation and Na2MoO4 doping
(ElsevierInternational Association for Hydrogen Energy, 2021-05-27)
We demonstrate the synergetic effect of Na2MoO4-doping and vacuum-annealing on dendritic nanostructured bismuth oxide (Bi2O3) thin films prepared by electrodeposition for visible-light-assisted photoelectrochemical (PEC) ...
Domain periodicity in an easy-plane antiferromagnet with Dzyaloshinskii-Moriya interaction
(American Physical Society, 2020-12-28)
Antiferromagnetic spintronics is a promising emerging paradigm to develop high-performance computing and communications devices. Antiferromagnetic materials are more abundant than ferromagnets; hence, from a theoretical ...
Time-expanded φOTDR using low-frequency electronics
(Optica Publishing Group, 2023-01)
Time expanded phase-sensitive optical time-domain reflectometry (TE-φOTDR) is a
recently reported technique for distributed optical fiber sensing based on the interference of two
mutually coherent optical frequency combs. ...
Current-controlled memristors: resistive switching systems with negative capacitance and inverted hysteresis
(American Physical Society, 2023)
Resistive switching in memristors is being amply investigated for different
applications in non-volatile memory (RRAM), neuromorphic computing and
programmable logic devices. Memristors are conducting devices in which ...
Charged Biological Membranes Repel Large Neutral Molecules by Surface Dielectrophoresis and Counterion Pressure
(American Chemical Society, 2024-01-31)
Macromolecular crowding is the usual condition of cells. The implications of the crowded cellular environment for protein stability and folding, protein–protein interactions, and intracellular transport drive a growing ...
