Spectroscopic Evidence of Edge‐Localized States in an Antiferromagnet Topological Insulator NdBi

Advanced Science, EarlyView.
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‐

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 ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

Considerações sobre o conceito de temperatura e de temperatura absoluta [PDF]

Revista Brasileira de Ensino de Física, 2006
Discute-se o conceito de temperatura que emerge da ação de contato, e a conveniência de torná-lo menos abstrato levando em conta a quantidade de matéria envolvida. Mostra-se que o conceito de 'energia térmica molar', numericamente igual ao produto da constante dos gases pela temperatura absoluta, preenche aquele fim, expressando o conteúdo cinético da ...

PODER TERMOELÉCTRICO DEL Ce(Pd1-xCux)2Si2

Anales (Asociación Física Argentina), 2014
Se presenta un estudio del poder termoeléctrico, S(T), a bajas temperaturas de la aleación Ce(Pd1-xCux)2Si2. Las curvas deS(T) tienen una dependencia similar en todo el rango de sustitución, con tres anomalías: un máximo positivo de altatemperatura, un ...

Ecología térmica de la lagartija de lava de Santa Cruz (Microlophus indefatigabilis) de Gálapagos, Ecuador: implicaciones del fenómeno de El Niño

Revista Mexicana de Biodiversidad, 2022
La temperatura es la principal variable ambiental de la que dependen las lagartijas para mantener sus procesos metabólicos, esta influencia el desempeño locomotor. Debido a esto, si la temperatura ambiental aumenta como consecuencia del cambio climático,

Local climate and genetic influence on intraspecific variation in torpor physiology of a cave‐roosting bat

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many small endotherms employ torpor as a survival strategy to reduce energy expenditure during periods with low food availability and cold temperatures. The expression and physiology of torpor can vary substantially within species because of phenotypic plasticity and ...
