Dear Dr. Zalkind,

We previously invited you to review the following manuscript, but have not
yet received a response. We have now received sufficient peer-review reports
from other referees and, in order to continue processing the paper, have
decided to cancel your invitation:

Type of manuscript: Article
Title: Surface Oxidation of Cu2O Nanoparticles by Adsorbed Ammonia

We apologize for any inconvenience this may cause and hope that we will be
able to call on you to review for Nanomaterials in the future.

MDPI is currently running a “Reviewer Recruiting Program”. The
participants of this program have the opportunity to apply to review
interesting manuscripts, through our editorial system, Susy. If you are
interested in this project, please visit the following link for suitable
manuscripts (https://susy.mdpi.com/reviewer/list/recommand_manuscripts).

We encourage you to submit your manuscript to Nanomaterials
(https://www.mdpi.com/journal/nanomaterials). Nanomaterials is open access,
and prides itself on its efficient peer-review process and fast feedback for
authors. Please note that article processing charges apply to accepted papers
to cover the costs of open access publishing (see
https://www.mdpi.com/journal/nanomaterials/instructions for details).

Kind regards,
