  1. Hace 11 horas · The absorption band at a photon energy of 3.1 eV (400 nm) does not appear in the interface between small diameter (less than 1 nm); therefore, the electrons cannot transfer from CNT to BNNT with ...

  2. I was working on an idea set in New Mexico, and Roswell being what it is, it made me wonder, what exactly is the explanation for the Roswell crash…

  3. Hace 2 días · Using this band, one can study electronic structure of water, aqueous solutions, and adsorbed water. (3) ATR–FUV spectroscopy has its own advantages of ATR method as a surface analysis method. ATR-FUV spectroscopy is a powerful method for exploring a variety of top surface phenomena (~50nm) of adsorbed water, polymers, graphene, organic materials, ionic liquids, and so on.

  4. Hace 3 días · The phenomenon of pulsar nulling, where pulsars temporarily and stochastically cease their radio emission, is thought to be indicative of a `dying' pulsar, where radio emission ceases entirely. Here we report the discovery of a long-period pulsar, PSR J0452-3418, from the ongoing Southern-sky MWA Rapid Two-meter (SMART) pulsar survey. The pulsar has a rotation period of ${\\sim}$1.67\\,s and a ...

  5. Hace 2 días · $1T$-transition metal dichalcogenides (TMDs) have been an exciting platform for exploring the intertwinement of charge density waves and strong correlation phenomena. While the David star structure has been conventionally considered as the underlying charge order in the literature, recent scanning tunneling probe experiments on several monolayer $1T$-TMD materials have motivated a new ...

  6. Hace 2 días · Consciousness, at its simplest, is awareness of internal and external existence. [1] However, its nature has led to millennia of analyses, explanations and debate by philosophers, theologians, and scientists. Opinions differ about what exactly needs to be studied or even considered consciousness.

  7. Hace 5 días · Theory . During tensile deformation materials initially deform elastically and the yield point marks the onset of plastic deformation. For most materials the transition from elastic to plastic deformation is gradual and hence do not exhibit a sharp transition point.
