I was looking into buying some copper sulfate from online for electroplating(apparently California Lowe’s or Home Depots don’t carry it for some reason anymore). Anyways, some of the best deals were around 40$ for 10 pounds, but most of the smaller batches were more like 10 dollars a pound, give or take. This got me thinking about the fact that it costs almost 10 dollars to ship a 1 pound package alone. How the heck does that work? Are they spending like a couple dollars to make it and 10 on shipping? And it’s like 20$ to ship a 10 pounds package, so even though it’s way better, that’s still 50% of the cost… is there some shipping loophole?

I have done 2 internships 1 in tech sales 2nd in metallurgy. I don’t really have interests in either of these fields as my only goals are to make money, good work life balance, job right after graduating.

I have a proposal to come back for both and one in a brewery. (3) Or should I continue applying in other fields ? (Which ones)

What should I choose?

Meron po ba may alam san po ako makakuha ng printable tabs for handbook? Ang mahal po kase bumili online. Tyia ☺️

hi dear people

i desprately need help

i want to define some untypical salts like: (Na)x (B)1-x O(1.5-x)
how can i define such things? its made out of NaOH and H3BO3
i tried different ways but each time i get different errors or in simulation it will give me errors
please help me to build such component as a solvent

Hello everyone,

I am a sophomore student and was wondering if there was anything you guys wished you knew before taking thermo. I am almost finished with this semester, and I'm satisfied with how i did in materials & energy balances, I've mostly read the book to study.

I am a bit scared about thermo next semester because of how the upperclassman are always talking about how much of a nightmare it was, and that semester will be a heavier course load. I do plan on reading the book, outside of that, are there any other resources you guys would suggest?

Thanks!!

Hi everyone,

This is probably a longshot, and I don’t know if I can even post about this, but would anyone happen to have an Ares G2 Mainboard they would be willing to part with/sell?

I graduated in July this year, I've been applying for jobs in the U.S. and in the country I studied (idk if this is relevant information but I'm a U.S. citizen but did not study in the U.S.), currently I live in Texas and I'm a bit desperate to start at a entry level job but no luck so far. Also I do have internship experience but it wasn't the best and ofc they were not hiring

Any hiring managers here looking to hire a MS or PhD is OaG or semiconductor industry?

Before write a comment read all edits.

I am a chemical engineer with experience in building web applications. I’m considering developing a custom Large Language Model (LLM) similar to ChatGPT, but specifically fine-tuned with chemical engineering references and additional data, such as a database of chemical reactions.

The goal is to create a tool that provides precise answers along with citations, including the reference title and chapter for better traceability.

As a chemical engineer, would you be interested in using a tool like this? If so, how much would you be willing to pay for a monthly subscription?

Edit: Many people said chatgpt already enough so as chemical engineer how do you think we can use llm models to improve our tasks?

Edit 2: So the next issue with the project will be data source and copyrights

Im a senior and I graduate this month. I decided to take a random class to be full time and I think Im going to fail it since I didn’t dedicate that much time to it. Im passing all my other classes pretty well. I have a 3.3 gpa. My question is will it lower my gpa low enough to where I won’t graduate. Also I have all my other extra credits and everything this was really a random class.

I am the senior year chemical engineering student and our design project is about production of Acrylic acid from biomass. Generally, kinetic data and possible steps for biomass are quite poor in the academic paper. However, there are plants (Arkema, France and Nippon from Japanese) that use different biomass sources to produce AA. Idk I’m struggling and write it down here

About to do university applications, can’t decide between chemical and mechanical. I don’t know what I want to do in future but I do really want to learn about engineering. I don’t really want to work with petroleum.

Any advice on how can I decide between them ?

I'm planning to study biochemical engineering in the UK and would appreciate any online resources that could help me prepare in advance. Additionally, if anyone who has graduated from University College London could share the materials they used during their MEng/BEng studies, it would be greatly appreciated.

So unfortunately I was let go beginning of November due to the company financial situation (bad timing considering the election and holidays). I have gone on unemployment and started the job search but I feel like every lead I have runs cold. Most of the positions I have networked for were filled by internal candidates. I feel like I also just don't have enough experience, as I was let go about a year and a couple months into the job. Should I go back to school? Should I pivot out of engineering? I was a process engineer for AEC, and did like my job enough, but keep hearing about layoffs happening at other firms and I would prefer not to experience this again lol.

Anyone have experience with interning in chem engineering at International Paper? Thoughts?

Thx.

Hello everyone, I live in the UK and I'm about to pick my university degree and I am unsure of what to pick. I have chemical engineering as a choice as it has a fair bit of maths physicś and chemistry which is what I'm good at. What could a role within an actual job with chemical engineering entail and what is a working environment like, especially in the UK. Is employment good or does the degree give you a variety of things to go into? Is the pay fairly well on average (of course depending on what you go into). I have no set idea as what I want to become, I'm just fairly decent at maths physicś and chemistry and I enjoy them more than other subjects.

Thanks

Hi all i’m a current sophmore chem e. Ive been looking into future plans and have been proposed a few routes, and my goal in all is to get into a management or leadership type of role. I’ve been told that if you want to go nuclear, the NUPOC program and becoming an officer in the navy is a great way. I’ve been told that an MBA would be more linear to get towards a management position. Lastly a friend of mine brought up pursuing a PhD and being a RA until complete; this would be my least favorite route due to the loss of profit that a job would bring in. All in all what would you suggest would be my best option(s) as someone who wants to make a good salary, get into a form of high level project management, and likes to work in high level chemical or thermo processes. thank you.

As a graduate whose forgotten almost everything I've studied. I have recently landed an engineering role and want to freshen up. Since I have a long commute, I'm curious to know if there are any podcasts or audibles to try recap on the foundation principles. Any thing of the sort out there?

Hi, im 18 and really like chemistry and i would like some advice on how to reach my goal of becoming a chemical engineer, any advice would help thanks

Hi guys, I’m gonna jump to the point, I just took the chemical PE exam this morning, geeez I feel an incredible amount of relief, the colors outside are a little bit more vibrant and the air smells a little sweeter. I just feel awesome. In the first half I had 39 questions then in the second half I had the remaining 41. In the first half I flagged 5 that bothered me a good amount and in the afternoon I flagged another 10. But the ones I flagged in the second half…I’ll be honest were complete guesses. The question were so dang specific and niche to the industry you’ve worked in. Lowkey not even fair hahaha. Anyway, what are yalls thoughts? I feel pretty good but I’m not sure if I’m getting ahead of myself, I really do think only those 15 were pretty iffy. the remaining questions that I answered, 80% of them I’m super confident and the others I’m like 75-85% sure I’m right. How many do yall think I can realistically miss before I’m in trouble? I’ll update yall as results come out.

Hi since graduating in 2023 I have been in a field service engineer role for a bioprocess controller. I want to get into more ocean/coastal/marine engineering and am willing to learn new softwares. Not only am I looking for a new full time role but I feel like I could pick up some contract projects on the side. I love project based work and would love something where I get paid per project. I am not sure the best way to go about that and if I would actually be trusted as an early career engineer to be freelance. Let me know I’m open to all advice

Dear fellow Chem Eng, currently in my first year of this esteemed degree. Long story short we got a group assignment for a BioChem class due Monday, and my group member cannot seem to find any info on the Flavr Savr Tomato (beyond surface level information) We specifically want to find out what lead to it ceasing in production and other regulatory and environmental impacts that came about because of it. Everything seems to be hidden behind paid research papers and we are broke students lol. Any and ALL information will be greatly appreciated.

how did you ace energy balances?

If people are spending more time thinking about how much they don't like your face they're just 1) not going to pay attention to what you're saying. 2) Not understand what you're saying (they weren't paying attention). & 3) Disagree or be combative.

I know this all too well. Which is why I often recruit the few people that like me to champion my ideas on my behalf.

It never occurred to me once that people explain things better than me. It did occur to me that effectiveness involves so many variables that are often beyond your control. An attractive person with a better reputation will often be more effective than their less attractive less popular counterparts. Even if they use the same wording. Persuasiveness in face to face situations involves much more than using the right words.

I've seen this so many times.

Let's talk about how I got into chemical engineering.

When I was young, I couldn't for the life of me make any friends. This happened throughout k-12. Throughout university. (I realize now that my face is too distracting for most people.) I'm not saying I'm a monster, but I am always a low priority for most people given our highly social world often prioritizes the most attractive people.

I don't blame people for this. But it did have an impact on my life.

If I was attractive, I would've had friends throughout my education. If I had friends, I wouldn't have been lonely. If I had friends when I was young and had been socially successful then I think I would have never gone into getting my degree. I know myself.

Anyways, back to what I was saying. I often recruit people to champion my ideas. I think I have great written communication skills in a professional setting but when it comes to verbal situations I am very ineffective. Being constantly excluded throughout all my youth just made me socially awkward. Having memories of constantly losing my audience within seconds of talking certainly doesn't help either. So I often use my go to people to speak on my behalf.

I've gotten the similar feedback from different parties in my life: You're good at explaining things to technical people, but not very good at explaining things to a people person (managers).

Does anyone have experience working for the CSB (Chemical Safety Board). Just saw a ChemE job for them posted on LinkedIn.

I have 20 years of experience; all in the private sector. I assume it would be a pay cut - are there other benefits that make up for it? Did you like working in government?

I hesitate to even apply because this sounds like the exact type of role that would be targeted for elimination under Trump and Elon’s DOGE committee.

I'm almost in my 3rd yr of chemical engineering undergrad and I'm mostly into hardware and designing domain. Im working on few hardware and electronic projects and it's not possible to get a job in that domain or even in designing right after graduating as a fresher. Im not much interested in core chemical engineering jobs and most of it are in O&G industries in my country. Im planning on doing a master's in hardware and electronic will it be helpful? Or should I take machine learning and data analysis as an elective?

Good morning, this semester of my second year of engineering I took analytical chemistry and I can say that I hated the class deeply. I found the lab to be pretty good but I didn't like the theoretical aspect of the class one bit. So I ask you, is the degree going to be similar in any way to this class or is it a requirement that is not very important (in case it is relevant, in the curriculum this class appears as a prerequisite for the Physical Chemistry Lab I, which in turn is a prerequisite for Thermo I). I ask you this because I have read that in this degree chemistry plays a secondary role, so to speak, but I would like to know your opinion.
Excuse any spelling mistakes, English is not my main language.

Hey y'all. So this semester I took general chemistry I and I liked it, especially stoichiometry and aqueous solutions. However, I heard upper level ChemE classes are nothing like this and focus more on heat transfer and thermo. Could someone elaborate on this? My least favorite chapter in gen chem was thermochemistry which could be a deal breaker.
