Metals

Metals, commonly used in cooking utensils and electrical wiring, are known for their high thermal and electrical conductivity. However, thermoelectric materials challenge this norm by efficiently conducting electricity while being poor conductors of heat.

Researchers

Dr. Ajay Soni, at the School of Physical Sciences, IIT Mandi, alongside his research team including Dr. Kewal Singh Rana, Mr. Aditya Singh, Ms. Nidhi, Mr. Animesh Bhui, Dr. Chandan Bera and Prof. Kanishka Biswas, has conducted an in-depth study on large unit cell mineral chalcogenides.

The research reveals that irregular atomic vibrations within the crystal lattices, which significantly reduces thermal conductivity, enhancing their effectiveness for thermoelectricity as well as for thermal management applications, say IIT Mandi researchers.

Impact

Dr Soni emphasized the impact of their findings.

Our research on the anharmonic rattling in sulfosalt tetrahedrites provides crucial insights at the atomic level for understanding the thermal conductivity on these solids, said Dr Soni of IIT Mandi.

‘This advancement holds the potential to revolutionize thermoelectric materials, leading to more efficient cooling systems and energy recovery technologies.’

Our research is supported by the core research grant of science and engineering research board, now ANRF, Govt India, he said.

Separate Study

Whereas, in a separate study, the team investigated superionic conductors that include silver and copper, known for their excellent ionic conductivity, say IIT Mandi researchers.

Although, these materials are crystalline in nature still their thermal conductivity is comparable to glassy materials.

These materials are even crucial for harvesting heat in mid temperature range, and for advanced battery technology and solid-state electrolytes for futuristic technologies.

This research marks an exciting advancement in materials science and energy technology, said Dr Soni of IIT Mandi.

Major Advancement

The research from IIT Mandi marks a major advancement in materials science by unveiling the origin of poor thermal properties. By elucidating how atomic vibrations influence thermal conductivity, the team’s work enables the design of materials with optimized thermal properties.

Potential

These discoveries have the potential to drive innovations in energy management and sustainability, say sources from IIT Mandi.

By significantly improving energy efficiency and advancing superionic conductors, this research offers promising pathways for creating more sustainable solutions across multiple sectors, say sources from IIT Mandi.

The transformative impact of these findings heralds a new era in materials science, paving the way for more efficient energy management and groundbreaking technologies across various industries.

The two papers that describe the above research have been published in esteemed journals including ‘ACS Applied Energy Materials’ and the ‘Journal of Materials Chemistry A of the Royal Society of Chemistry’

They also include, School of Mathematical and Statistical Sciences (SMSS), School of Physical Sciences (SPS), School of Mechanical and Materials Engineering (SMME).

Also among them are, School of Civil and Environmental Engineering (SCENE), School of Computing and Electrical Engineering (SCEE), School of Humanities and Social Sciences (SHSS), and School of Management (SOM).

The research centers are the Advanced Materials Research Centre (AMRC), Centre for Design and Fabrication of Electrical Devices (C4DFED), BioX Centre.

The schedule to submit applications for JEE Advanced 2025 has been announced along with that of AAT 2025 registration,

Application process for AAT starts after result declaration of JEE Advanced. This year too, the trend is no different.

Who will conduct AAT 2025?

AAT 2025 will be conducted by IIT Kanpur and is expected to see a participation in impressive numbers. The same institution is conducting JEE Advanced 2025.

Details about the exam are available on the official website mentioned above. Students who pass AAT 2025 will be able to study BArch in IIT Roorkee, IIT Kharagpur and IIT (BHU) Varnasi.

Who can take up AAT 2025 registration?

Students who have passed JEE Advanced 2025 with required qualifying marks can take up AAT 2025 registration. Applying for JEE Advanced requires a pass in JEE Mains.

Candidates who have passed plus two with maths, physics and chemistry as subjects will be able to take up JEE Mains registration. The process to take up JEE Advanced AAT 2025 registration is online.

3. Post providing the above details, applicants will be asked if they are interested in AAT. Students have to answer ‘Yes’ to take up JEE Advanced AAT 2025 registration.

4. Candidates have to provide the required information and choose the centers where they wish to write the exam and submit the form.

5. They will receive message indicating successful completion of JEE Advanced AAT 2025 registration.

The message has to be downloaded and a printout of it has to be taken and preserved for use in future. This could be of use during the admission process.

Website for JEE Advanced 2025/AAT 2025 Registration is Here

Exam pattern

Candidates who have completed JEE Advanced AAT 2025 registration must also know the exam pattern if they are to score good marks.

Those who have taken up AAT 2025 registration can take up the exam which will be held in offline mode, as a pen and paper mode test.

Candidates will have three hours time to answer all the questions. The medium of the test is English.

The sections in the question paper are – Imagination and aesthetic sensitivity, three dimensional perception, Geometrical drawing, Freehand drawing and Architectural Awareness.

Syllabus for AAT 2025

The next thing to do after completing AAT 2025 registration is focus on preparing for the test.

The subjects to be studied while preparing for AAT 2025 are mentioned below. Candidates can also refer the official website for more information on syllabus when the registration for the exam begins:
