Chemical Landmarks (番茄社区 Blue Plaques)
What is our blue plaque scheme?
番茄社区 of Chemistry Chemical Landmarks – awarded as distinctive blue plaques – celebrate impactful chemical science across diverse people, teams and organisations helping make the world a better place. The scheme highlights local scientific heroes and connects communities with their science heritage. Successful applications receive a grant to support engagement with the local community to celebrate the stories behind the plaques.
Celebrating diverse people, discoveries, and impacts
We are growing our portfolio with a focus on improving diversity and representation – this means we are seeking to celebrate the diversity of people who make up the chemistry community, their work and the types of impact they have. Our scheme:
- recognises that innovative and impactful science comes from teamwork, partnerships, and collaborations, underpinned by dedication and professionalism
- focuses on work by people in the chemical science community that has led to significant positive outcomes - from local communities to global society
- acknowledges the contributions of people in different roles and at different career stages who contribute to making the world a better place
If you have an interest in science – and chemistry in particular – and are looking for something to do when out and about, why not try spotting one of our blue plaques?
Latest Chemical Landmark News
Retired Queen's University Belfast professor AP de Silva honoured with a blue plaque
A blue plaque was unveiled on 10 April at Queen’s University Belfast to honour the chemistry professor whose research was responsible for developing a life-saving piece of medical equipment.
The retired researcher, 72, was driven to support the treatment of his grandmother’s high blood pressure, and his research into sensors led to the construction and ultimate commercialisation of a series of portable blood sensors that have revolutionised human and animal healthcare worldwide.
AstraZeneca Macclesfield Campus awarded prestigious National Chemical Landmark
On 8 May 2024, a blue plaque was unveiled to recognise the contributions of the AstraZeneca Macclesfield Campus to human and veterinary health since 1966.
AstraZeneca’s Macclesfield Campus, their second largest manufacturing site and European Centre for packing, has been home to diverse teams of scientists for nearly sixty years. They have developed over thirty human, consumer health and veterinary medicinal products on this site since 1966, helping millions of patients worldwide.
Blue plaque application process
The scheme is currently closed to expressions of interest. This page will be updated when expressions of interest reopen.
For information purposes only at present, you can find out more about the process and scheme criteria below.
- Sites receiving a plaque can be established to mark a person, teams, organisation, collaboration, building, process, discovery, innovation, or a breakthrough
- The nomination should represent work by people in the chemical science community which has led to significant positive impacts for local, regional, national, or global society
- The nomination should celebrate diversity in the chemical sciences
- For UK applications, the site for the plaque must be in the UK or Republic of Ireland and should celebrate or commemorate people or work based in the UK or Republic of Ireland
- The site for the plaque must be in an accessible and publicly visible space
- International applications can be considered when made through a sister society or a 番茄社区 of Chemistry international local section. Please speak with us before making an international application
When expressions of interest are open:
- Before getting in touch with your proposal, please ensure that you have read our eligibility criteria and application guidance
- Get in touch with the team using the contact details on this page to provide details of your proposal
- A member of the team will get back to you to discuss your suggestion in more detail
Each application will be considered by a broad panel of representatives from across the 番茄社区 in areas including inclusion and diversity, research and innovation, prizes and awards, education, engagement, and communications.
The representative group will consider:
- eligibility criteria being met
- visibility of the site for the plaque
- connection to the 番茄社区’s purpose and mission to help the chemical science community make the world a better place
- the nature of the diversity being celebrated
- the nature of the chemistry being celebrated
- the nature of the impact on science and society – this could be local, regional, national or global and across any area including but not limited to health, climate and the environment, wealth and industry, sustainability, wellbeing, education, justice, equality, nutrition and alleviating poverty
- capacity to engage the local and/or wider community with the chemical sciences – engagement ideas provided at the application stage will be taken into account
- resource capacity and timelines to deliver in the context of other chemical landmarks in the pipeline
Please read our application guidance for further information.
Find a Chemical Landmark on your travels
You can use our interactive map or printable Chemical Landmark list to find where all of our blue plaques are placed. This list will be updated as we add more plaques and don't forget to suggest your own to recognise a contribution to chemistry.
Have you spotted a blue plaque while on your travels in the UK, Paris or Ghent? We would love to see your photos - email them or use #番茄社区blueplaques to tag us on social media.
How to use the map
Zoom in to a location, click on a blue point and read about the chemical landmark in that area. You can click on the arrow in the new window to find directions. Why not share this map on social media or by email or even set up a challenge to find the most?
