Digestión anaerobia a bajas temperaturas [PDF]

, 2022
Low speed anaerobic digesters are commonly used to produce energy from livestock manure (pig and / or bovine) on small and medium-sized farms; However, its use in cold climates faces the limitation of the decrease in biogas production and the potential failure due to acidification of the bed, not only due to the low environmental temperature, but also ...

Gapless Superconductivity From Extremely Dilute Magnetic Disorder in 2H-NbSe_2-xS_x. [PDF]

Adv Mater
We demonstrate that 2H‐NbSe2‐xSx hosts gapless superconductivity at unexpectedly low magnetic impurity concentrations. Combining STM, Bogoliubovde Gennes simulations, DFT, and quasiparticle interference, we comprehensively study the development of gapless behavior and show that SeS substitution reshapes the band structure, enhances nesting, and drives ...

Signatures of Edge States in Antiferromagnetic Van der Waals Josephson Junctions. [PDF]

Adv Mater
ABSTRACT The combination of superconductivity and magnetic textures leads to unconventional superconducting phenomena, including new correlated and topological phases. Van der Waals (vdW) materials emerge as a versatile platform for exploring the interplay between these two competing orders.

Spectroscopic Evidence of Edge-Localized States in an Antiferromagnet Topological Insulator NdBi. [PDF]

Adv Sci (Weinh)
Using spin‐polarized scanning tunneling microscopy (STM) in conjunction with quasiparticle interference, we successfully identify distinct signatures of the ferromagnetic and antiferromagnetic terminations in NdBi, a rare‐earth monopnictide exhibiting non‐trivial topology and magnetism. We demonstrate that step edges on ferromagnetic surfaces host well‐

1D charge density wave in the hidden order state of URu2Si2

Communications Physics, 2021
URu2Si2 is known to exhibit a lower temperature phase transition termed a ‘hidden order’ due to the difficulty its detection using conventional solid-state probes and the exact mechanism still remains unknown.

Field-Induced Antiferromagnetic Correlations in a Nanopatterned Van der Waals Ferromagnet: A Potential Artificial Spin Ice. [PDF]

Adv Sci (Weinh)
CrGeTe₃ nanoislands exhibiting tunable dipolar interactions resulting in an effective inter‐island antiferromagnetic coupling are demonstrated. The crossover between random and anticorrelated islands depends on their spatial distribution. The dipolar interaction enables the formation of complex magnetic patterns, which can be harnessed to generate more

Caracterización de películas delgadas mediante efecto MOKE a bajas temperaturas

, 2022
En este trabajo se midieron las curvas de histéresis dos películas delgadas Co(10)/Ag(2) y Co(2.6)/Nb(1) usando los magnetómetros T-MOKE y VSM. En el montaje T-MOKE se hicieron mediciones con dos configuraciones para el procesamiento de señales.

Temperature Conditions in Artificial Sea Turtle Nests: Toward Optimized Hatchery Management. [PDF]

Ecol Evol
This study examined how environmental and management factors, such as wall distance and egg numbers, influence nest temperatures of Olive Ridley sea turtles in a hatchery on the Pacific coast of Guatemala. ABSTRACT Climate change poses a significant threat to species with temperature‐dependent sex determination, such as sea turtles.

Methods to simplify cooling of liquid Helium cryostats

HardwareX, 2019
Liquid Helium is used widely, from hospitals to characterization of materials at low temperatures. Many experiments at low temperatures require liquid Helium, particularly when vibration isolation precludes the use of cryocoolers and when one needs to ...
