認識飛沫和飛沫核

Understand the droplets and droplet nuclei

當人說話、打噴嚏或咳嗽等過程中產生大粒徑（大於5微米）的飛沫，一般來說，可飛行的距離約為1公尺（3英呎）；當飛沫中含有病毒等病原體時，近距離的接觸可增加人體感染的機會，稱為「飛沫傳染」。因此對於患有呼吸道感染的病人而言，除了建議配戴一般醫用口罩，以避免咳嗽等症狀造成病原體傳播給他人之外，也建議呼吸道感染病人和他人交談時保持至少1公尺以上的距離，以降低飛沫傳染的風險。此外，人在說話或打噴嚏時產生的大粒徑飛沫會沉降於地面或物體表面，所以正確的洗手動作、經常清潔與消毒各種物品表面（如桌面、地板、儀器設備、玩具等），以及採取妥善食物覆蓋等措施，均可避免飛沫污染，這些都是民眾應該養成的重要生活習慣。When people talk, sneeze, or cough, they generate droplets of large particle size (greater than 5 microns). Generally speaking, the flying distance is about 1 meter (3 feet), when the droplets contain pathogens such as viruses, then close contact can increase the chance of human infection, which is called “droplet infection.” Therefore, for patients with respiratory tract infections, apart from wearing medical masks to avoid symptoms such as coughing from spreading pathogens to others, it is also recommended that patients keep a distance of at least 1 meter when talking with others, in order to reduce the risk of droplets infection. In addition, the large-particle droplets generated when people speak or sneeze will settle on the ground or the surface of objects, so correct hand washing procedures, frequent cleaning and disinfection of various surfaces (such as floors, desktops, equipment, toys, etc.), and proper food coverage can prevent droplet pollution. These are important living habits that people should develop.

上述提及人體會產生大粒徑的飛沫，其實也會產生細小飛沫。當含有病原體的飛沫直徑≤ 5微米時，就有空氣傳染的風險。前面內容提到含有病原體的大粒徑飛沫，一旦在濕度較低的室內環境中，飛沫外部的水分蒸發將會形成細小的「飛沫核」，便可在空氣中懸浮較長的時間，若病原體本身特性又可適應該環境，也就是可以安全存活下來，此時，就有空氣傳染之虞，例如：人體吸入空氣中含有1～5微米的結核桿菌飛沫核，就可能導致肺結核病。

As mentioned above, the human body can produce droplets of large particle size, but in fact, it also produces fine droplets. When the droplets containing pathogens are smaller than 5 microns in diameter, there is a risk of airborne infection, The previous content mentioned that large-size droplets containing pathogens, once in a low-humidity indoor environment, the moisture outside the droplets will evaporate to form tiny “droplet nuclei” that can be suspended in that air for a long time. If the pathogen itself can adapt to the environment, that is to say, it can survive safely. At this time, there is a risk of airborne infection. For example, if the human body inhales the air containing 1 to 5 microns of tubercle bacillus droplet nucleus, it may cause tuberculosis.

至目前為止，現有的科學證據初步顯示COVID-19主要是以近距離的飛沫及接觸傳染，仍未有充足證據指出COVID-19會以空氣傳播方式造成人類感染，至於COVID-19是否會造成空氣傳染，此待未來更多的研究證明。

Up to present, the existing scientific evidence has preliminarily shown that COVID-19 is mainly transmitted by close-range droplets and contact. There is still insufficient evidence to indicate that COVID-19 will cause human infections by air transmission. As for whether COVID-19 will cause airborne infection or not, this is to be proved by more research in the future.

如何使用「銀銅鈦濺鍍技術」殺死病毒

How Does ACT Sputtering Technology Kill The Viruses？

在許多人的認知中，冠狀病毒在銅金屬的表面上，存活最短。但事實上，病毒在銀金屬的表面上存活時間更短。

Many people think that the coronavirus has the shortest lifetime on copper. But in fact, the virus survives for a shorter time on silver.

但是銅的表面是單一的銅原子，銅原子本身的價電子，(或是對銀來說，除了價電子之外，還包括銀表面氧化之後的銀離子)，會讓靠到上面的細菌的包膜與病毒的外套膜，逐漸地被價電子所破壞掉而無法存活。但是畢竟效果比較離子的放電速率與效果為慢，所以銅原子消滅新冠病毒需要四個小時的時間。而即便我們是用市面上常見到的銀離子來消滅新冠病毒，雖然快速，但是很容易因為離子不斷的析出而逐漸喪失滅菌的功效。

However, the surface of copper is a single copper atom, and the valence electrons of the copper atom (or for silver, in addition to the valence electrons, it also includes the silver ions, that appears after oxidation of the surface of the silver), will destroy the envelopes of bacteria and virus, so they won’t be able to survive. But after all, the effect is slower than the discharge rate and effect of ions, so it takes four hours for copper atoms to kill the new coronavirus. Even if we use silver ions that are commonly found in the market, it might be fast, but it is easy to gradually lose the effect due to the continuous precipitation of ions.

若使用的銀銅原子氧化還原電位差的原理，不但藉由銀銅原子表面的價電子雲的分布，大幅強化了織物表面的殺菌能力，同時可以藉由這種沒有化學反應的物理抗菌技術，大幅延長材料的抗菌的效果，持久不會衰退。可以在一小時之內，消滅所有比較難消滅的無套膜病毒(例如腸病毒)，同時對於結構類似新冠病毒的另一種冠狀病毒(CoV-229E)的實測效果更好(如圖所示)，預估對於新冠病毒的活性降低，將有革命性的效果。

By using the Oxidation-Reduction Potential of Ag and Cu atoms, not only greatly enhances the sterilization ability of the fabric surface through the distribution of the valence electron cloud on the surface of Ag and Cu atoms, but also can use this physical antibacterial technology, that does not contain any chemical reactions, to greatly extended the antibacterial time of the materials, and it will not decline for a long time.

Also, it can kill all viruses without an envelope (such as enterovirus) within an hour, and the effect on another coronavirus (CoV-229E), which is similar in structure to the new coronavirus, is better (as shown in the picture). It is estimated that it will have a revolutionary effect of reducing the activity level of the new coronavirus.
