3 . People have come to understand the enormous impacts-beneficial as well as harmful- plastics have on human lives and the environment. As polymer (聚合物) scientists committed to inventing sustainable solutions for real-world problems, we set out to tackle the issue of plastic waste by rethinking the way polymers are designed so we could make plastics with recyclability built right in.

Everyday items including milk jug, grocery bags, and takeout containers are made from a class of polymers called polyolefins. These plastics are really durable (耐用的) because the chemical bonds in those polymers are extremely stable. In a world set up for disposable (一次性的) items, durability is no longer a design feature but rather a design drawback. Imagine if half the plastics used today were recyclable through twice as many processes as they are now. Also conventional recycling requires careful sorting of all the collected materials, which can be challenging with so many different plastics. For example, separating paper from metal doesn’t require complex technology, but sorting a container from a milk jug of a different polyolefin is difficult to do without the occasional mistake.

In a study published in Science in October 2023, we described a series of polymers with only two building blocks-one soft polymer and one hard polymer-that behave like polyolefins but could be chemically recycled. Connecting two different polymers multiple times until they form a single, long molecule (分子) creates what’s called a multiblock polymer. By changing how much of each polymer type goes into the multiblock polymer, our team produced a wide range of materials with properties that covered all polyolefin types.

Using the same strategy but by adding hydrogen, we could disconnect the polymers back into their building blocks and easily separate them to use again. When we made new polymers out of these recycled plastics, they performed just as well as the original materials even after several rounds of chemical recycling. So we were able to create materials with similar properties of the plastics the world relies on. We believe this work is a step toward more sustainable plastics.

7 . Get ready to start your journey to the best public university system in the world-with just one application.

Apply for more than one UC campus

This will significantly increase your chances of being admitted to the UC system. While you may not receive an offer of admission from your first-choice campus,all of our campuses-without exception-provide outstanding opportunities for you to learn and grow.

Apply on time

You can fill out the application in as many sessions as you want. Just remember to submit it by November 30 for the fall term.

Create an account

An email address and password are required in order to create an account. You should use the email account you use for all applications, just to make it easier to remember. We also recommend you use a non-school issued email account e. g. Gmail, Yahoo. Campuses send important and time-sensitive correspondence to applicants, so you should check your email regularly to follow up on your application.

9 . How to Organize Your Digital Files

Searching for a file on your computer is a whole lot easier than digging through a pile of papers, yet it’s far from being a perfect system. Lately, it’s been hit-or-miss for me.     1     I hope some of these tips will help you.

Use “resources”, “in progress”, “final”, and “scrap” folders for projects.

There are plenty of ways to title your subfolders for projects, but one of the most intuitive(使用简便的) is to have folders for stages of your project.     2    

The “resources” folder is for things like images, documents, and other items that are needed to complete your project.     3    “Final,” as you might imagine, is for the project files once the project has been approved and is done. “Scrap” is for anything you want to save from the project that doesn’t belong in the “final” folder.

    4    

It’s near impossible to find a photo quickly when you have thousands of photos all named something like “20211108_0978234.jpg.” So for photos, I like to have a date structure and folders for key events or categories, such as: 2021 ＞01 (for the month)＞2021-01 Mom and Dad 50 Anniversary LA. This way, you can either browse your photos by year and month or search for folders that include “Mom”, “Dad”, “Anniversary”, or “LA.”

Use tags.

In addition to creating a folder structure that works for you, consider tagging files.     5     Say, for example, you want to see all of your photos for all of your holiday celebrations. You can set up a tag for “holidays.” And then to narrow down the results, you can search using the tag.

A．With tags, you can connect multiple files across folders.

B．For photos, use a date structure and keywords for your folders.

C．This way, you can always know which is the final project file to grab.

D．The standards will keep files organized and make them easier on the eye.

E．“In progress” is for the current working version or versions of the project.

F．To find files more efficiently, I’ve been rearranging my digital filing system.

G．Move your photos to a more specific folder or back them up on an external storage device.
