Can I claim expenses to lower the taxable amount reported on a 1099?

I am presenting at a museum conference later in August on technology and education. I have a feeling that my stipend will be reported on a 1099... Isn't that heavily taxed as an independent contractor? Annnnd.... If I were to purchase a laptop (easy to justify the need for the intent of workshop), can that be claimed as an expense to lower the taxable remainder as "income?" Thanks for any feedback and advice!
