심하게 풍성한 : 실리콘에서 수소 동위 인터넷 바카라 주소 풍부하게하는 에너지 효율적인 방법

Scientists discover an inexpensive reaction to exchange light 인터넷 바카라 주소 for its heavier isotopes using silicon surfaces, paving the way to more durable electronics.

인터넷 바카라 주소 원자의 무겁지만 덜 풍부한 버전 인 중인터넷 바카라 주소는 불행히도 중인터넷 바카라 주소를 생산하고 실리콘 기반 반도체를 보호하기 위해서는 많은 에너지와 매우 비싼 중인터넷 바카라 주소 가스가 필요합니다 나노 결정 실리콘 표면의 중인터넷 바카라 주소에 대한 인터넷 바카라 주소 원자를 스왑하기위한 에너지 효율적인 교환 반응을 발견했다.

The discovery of 인터넷 바카라 주소 in the early 20th century marked a key moment in the history of physics and led to a much more refined understanding of the atomic nucleus. 인터넷 바카라 주소 are ‘versions’ of a given element of the periodic table that bear the same number of protons but a different number of neutrons, and therefore vary in mass. These differences in mass can radically alter certain physical properties of the atoms, such as their radioactive decay rates, their possible reaction pathways in nuclear fission reactors, and much more.

While most isotopes of an element share similar chemical properties, there is one notable exception: 인터넷 바카라 주소 isotopes. Most 인터넷 바카라 주소 atoms on Earth contain only one proton and one electron, but there exist 인터넷 바카라 주소 isotopes which also have one neutron (deuterium) or two neutrons (tritium). Deuterium, which essentially weighs twice as much as ‘normal’ 인터넷 바카라 주소, has found many practical and scientific uses. For example, it can be used to label and track molecules such as proteins to investigate biochemical processes. It can also be strategically used in drugs to reduce their metabolic rate and increase their half-life in the body.

Another important application of deuterium exists in the field of semiconductor electronics. The surface of silicon-based semiconductors has to be ‘passivated’ with 인터넷 바카라 주소 to ensure silicon atoms don’t come off (desorb) easily, thereby increasing the durability of microchips, batteries, and solar cells. However, through mechanisms that are still not completely understood, passivation with deuterium instead of 인터넷 바카라 주소 results in desorption probabilities about one hundred times lower, implying that deuterium may soon become an indispensable ingredient in electronic devices. Unfortunately, both the procurement of deuterium and available techniques to enrich silicon surfaces with it are very energy inefficient or require very expensive deuterium gas.

Fortunately, at Nagoya City University (NCU), Japan, a team of scientists led by Professor Takahiro Matsumoto have found an energy-efficient strategy to enrich silicon surfaces using a dilute 인터넷 바카라 주소 solution. This study, which was published in물리 검토 자료, 일본 원자 인터넷 바카라 주소 기관의 Takashi Ohhara 박사와 교토 대학의 Yoshihiko Kanemitesu 박사와 협력하여 수행되었습니다.

This innovative strategy of exploiting quantum effects on the surface of n-Si could pave the way to new methods to procure and utilize deuterium. “The efficient 인터넷 바카라 주소-to-deuterium exchange reaction we reported may lead to sustainable, economically feasible, and environment-friendly deuterium enrichment protocols, leading to more durable semiconductor technology,” concludes Dr. Matsumoto.

The NCU team also stated that “It has been theoretically predicted that the heavier the 인터넷 바카라 주소 is, the higher the efficiency of the exchange reaction is. Thus, we can expect more efficient enrichment of tritium atoms on n-Si, which leads to the possibility of purifying tritium contaminated water. We believe that this is an issue that must be urgently solved.”

Let us hope the findings of this work allow us to benefit more from the heavier isotopes of 인터넷 바카라 주소 without taking a toll on our planet.
