History of the Conferences on

Chemistry and Physics at Low Temperatures


The CPLT conference series resulted from the merger of two long-standing international conferences: the Gordon Conference on the Chemistry and Physics of Matrix-Isolated Species and the International Conference on Low Temperature Chemistry

First conferences

The first united CPLT conference was organized by Mika Pettersson and Jan Lundell in 2013 in Jyväskylä, Finland. CPLT 2014 took place in Suzdal, Russia organized by Vladimir Feldman and Tatyana Shabatina.

Recent conferences

CPLT 2016 was organized by Joëlle Mascetti, Claudine Crépin, and Stéphane Coussan and took place in Biarritz, France. CPLT 2018 was organized by David Anderson and Robert Hinde in Laramie, Wyoming . CPLT in 2022 will be held in Sapporo, Japan

The most interesting topics

Location: Hall 1

The thing with heat is, no matter how cold you are, no matter how much you need warmth, it always, eventually, becomes too much.

Location: Hall 1

Nothing burns like the cold. But only for a while. Then it gets inside you and starts to fill you up, and after a while you don't have the strength to fight it.

The time to speak of the cold is not when we are standing put in it.

Location: Hall 1

We are much too hot to feel the cold.

He who cannot put his thoughts on ice should not enter into the heat of dispute.

Location: Hall 1

ice contains no future , just the past, sealed away. As if they're alive, everything in the world is sealed up inside, clear and distinct. Ice can preserve all kinds of things that way- cleanly, clearly. That's the essence of ice, the role it plays.

Location: Hall 1

Ice is most welcome in a cold drink on a hot day.

Travel and accomodation

The CPLT 2020 Conference, has been postponed to 4 - 9 July 2021 in Visegrád, Hungary, due to the COVID-19 outbreak.

The CPLT Committee puts the health and welfare of participants and the local host community at the forefront of its decision making. The increased risk regarding the global spread of COVID-19 and the travel restrictions that are changing daily led us to take this decision. We are also aware that domestic and international restrictions are impacting the ability of many colleagues to participate.

Can I simply transfer my registration fee to the new conference dates?
Yes. The conference is postponed rather then cancelled so all paid registrations (including accomodation) and other fees via CPLT online registration page or by wire transfer are valid and automatically transferred for the 2021 conference with unchanged service content.

Yes. To transfer your registration to another person, please email CPLT2020 with the original delegate’s registration full name and provide us with the new delegate’s information.

If your are unable to participate or to donate your registration at the new time, please notify us by sending an email to cplt@conn2000.com requesting a refund by May 15, 2020.

Please ask your travel agent/airline and let them know you are cancelling or modifying your booking due to the postponement of CPLT 2020 in light of the COVID-19 pandemic. The responsibility for airfare bookings and refunds falls outside the scope of CPLT 2020 and will be dependent on the type of fare booked, the airline’s or agent’s own cancellation/rebooking policies regarding COVID-19, and any travel insurance coverage.

How to register?
Registration, travel and accomodation will be handled by the travel agent, Connections2000. Do not book the hotel individually. Please contact them with questions not connected with the scientific program.
The travel agent will accept credit cards via a secure homepage and bank transfers.
The location is easily accesible by car. The Conference provides transfer services for a fee on the first and last day of the conference between Budapest, Budapest Airport and Visegrád. See the details under Registration info. You can book your transfer during the registration process. Public transport is also possible: details below.

Frequent trains connect Budapest (Station Nyugati) to Nagymaros-Visegrád, from where a ferry crosses the Danube to the hotel. The same train line has direct trains to Bratislava and Prague every two hours from Nagymaros. Schedules and online tickets

There are riverboats (slow boat and express hydrofoil) taking the very scenic river route from downtown Budapest direct to Visegrád. See online schedules and book tickets.

Intercity buses also arrive directly to the hotel from the bus station at Újpest-Városkapu metro station. See online schedules Tickets are to be bought at the bus station.

Is there guarded parking?
Yes, provided by the hotel.

Early registration ends February 28, 2021.

Oral contribution are expected by April 15, 2021.

Poster abstracts before June 7, 2021.

Late registration (at +15% increased fee) is from June 5, 2020.

Are there reduced student options?
Yes, we arranged a budget hotel to be available nearby. Student groups (from 5 students) can inquire about special reduced rates at cplt@conn2000.hu.
Are there sponsorship opportunities for students?
We hope to find sponsors supporting student participation (not more than 50% reduction). Students in need should register here with a short motivation letter and recommendation from their advisor before February 20th. No payment should be made until the decision is received.
