Frequently Asked Questions

For students

If I order a paper sample does that mean I'm cheating?

Not at all! There is nothing wrong with learning from samples. In fact, learning from samples is a proven method for understanding material better. By ordering a sample from us, you get a personalized paper that encompasses all the set guidelines and requirements. We encourage you to use these samples as a source of inspiration!

Why am I asked to pay a deposit in advance?

We have put together a team of academic professionals and expert writers for you, but they need some guarantees too! The deposit gives them confidence that they will be paid for their work. You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

For teachers & parents

Are you a regular online paper writing service?

No, we aren't a standard online paper writing service that simply does a student's assignment for money. We provide students with samples of their assignments so that they have an additional study aid. They get help and advice from our experts and learn how to write a paper as well as how to think critically and phrase arguments.

How can I get use of your free tools?

Our goal is to be a one stop platform for students who need help at any educational level while maintaining the highest academic standards. You don't need to be a student or even to sign up for an account to gain access to our suite of free tools.

How can I be sure that my student did not copy paste a sample ordered here?

Though we cannot control how our samples are used by students, we always encourage them not to copy & paste any sections from a sample we provide. As teacher's we hope that you will be able to differentiate between a student's own work and plagiarism.

This process presumably proceeds by a pericyclic reaction and is rendered irreversible by oxygen. Jul 09,  · This paper presents a density functional theory study of the ruthenium-catalyzed olefin metathesis reactions. The ligand binding energy has been calculated in the first generation of Grubbs-type (PCy 3) 2 Cl 2 Ru CHPh (pre)catalyst, as well as in the heteroleptic (pre)catalytic systems in which a N-heterocyclic carbene, NHC, ligand substitutes a single phosphine. Olefin Metathesis Grubbs Reaction. Olefin Metathesis allows the exchange of substituents between different olefins - a transalkylidenation.

Oct 22,  · Abstract. Since the development of Grubbs catalysts of the first ([RuCl 2 (PCy 3) 2 (CH C 6 H 5)] (1 ; Cy=cyclohexyl) and second (2) generation, many modified ruthenium complexes for olefin metathesis have been reported, 1 for which strikingly different influences of the ligands on the efficiency of C C bond formation have been observed.
