These surfactants have their hydrophilic head and their hydrophobic tails, and so they form these micelles around the dirt, which is what grabs onto dirt and oil, and helps it to remove it from the hair and the scalp.

这些表面活性剂有亲水的头部和疏水的尾部，所以它们在污垢周围束，这些束可以吸附污垢和油，并帮助它们从头发和头皮清除。

I coated this glass with a hydrophobic coating that does just that.

我用给这个玻璃加了有那个功能的疏水涂层。

When you surround a coronavirus with water, the hydrophobic effect gives the bonds within the membrane their strength.

你用水裹住新冠病毒时，它的疏水效应会让膜内结构更坚不可摧。

The tail is hydrophobic, which means it repels water and instead attaches itself to oils or fats.

尾巴是疏水的，这就意味着它可以排斥水分子，而是附着在油。

Experts suspect the surfaces may be covered with some kind of hydrophobic material that repels water molecules.

专家揣测其表面可能覆盖有排斥水分子的疏水材料。

Their tails, which are similarly repulsed by water, compete for space with the lipids that make up the virus's shell.

它们疏水的尾部会与构病毒外壳的质争夺空间。

If that angle's more than 150 degrees, then it's superhydrophobic.

如果那个角度超过150度，那么该表面就是超疏水的。

The pepper extract sample goes into a column that's packed with hydrophobic particles that attract capsaicin.

辣椒提取物样本进入了一根装满疏水颗粒的柱子，这些颗粒会吸引辣椒素。

And so the drop just pulls itself into this round shape and we get a really large superhydrophobic contact angle and that water just ends up rolling right off.

因此，水滴会自行收缩圆，极大的超疏水接触角，最终水滴会直接滚落。

But most of what makes water roll off a duck's back are these superhydrophobic microstructures.

但让水珠从鸭背滑落的主要因素，正是这些超疏水的微观结构。
