Abstract
Irving Langmuir foi um múltiplo cientista porque atuou significativamente em várias áreas científicas. Os estudos de Langmuir abrangeram química, física, e engenharia, e foram, em grande parte, pioneiros nos aspectos de fenômenos no vácuo. O seu trabalho com o comportamento dos gases em filamentos levaram à invenção da lâmpada incandescente cheia de gás e a descoberta do hidrogênio atômico. Ele foi o primeiro a observar camadas monoatômicas estáveis em tungstênio e em fios de platina, e realizou experiências com filmes de óleo em água, formulando uma teoria geral de adsorção em filmes finos e estudou as propriedades catalíticas desses. Em química, o seu interesse em
mecanismos de reação o fez estudar estrutura e valência, contribuindo para o
desenvolvimento da teoria de compartilhamento de elétrons do Lewis.
Irving Langmuir was a multiple scientist because he worked in several scientific areas with full success. Langmuir's studies embraced chemistry, physics, and engineering and were largely the outgrowth of studies of vacuum phenomena. His work on filaments in gases led directly to the invention of the gas-filled incandescent lamp and to the discovery of atomic hydrogen. He was the first to observe the very stable adsorbed monatomic films on tungsten and platinum filaments, and was able, after experiments with oil films on water, to formulate a general theory of adsorbed films. He also studied the catalytic properties of such films. In chemistry, his interest in reaction mechanism caused him to study structure and valency, and he contributed to the development of the Lewis theory of shared electrons.
