This new, sustainable development contributes to harnessing a renewable energy source for detoxifying harmful substances such as chemical warfare agents, say sources from IISER Bhopal

Advancement

This research represents a significant advancement in the field of ‘Photocatalysis’, a process where a substance (a photocatalyst) is used to change the rate of a chemical reaction when exposed to light.

Material

But this novel photocatalyst developed by IISER Bhopal researchers solves that problem. This newly-developed material called ‘UC-POP-Au’ displays remarkable strength and catalytic efficiency as it absorbs the entire spectrum of light, making it a more potent catalyst during chemical processes.

Findings

The findings of this research by IISER Bhopal researchers have been published in the peer-reviewed journal Angewandte Chemie (D.O.I: https://doi.org/10.1002/anie.202312910) in a paper co-authored by Prof. Abhijit Patra, Department of Chemistry, IISER Bhopal, and his research scholars, Ms. Shilpi Jaiswal, Dr. Arkaprabha Giri, Dr. Dependranath Mandal, and Ms. Madhurima Sarkar.

He said the current investigation unveils a novel direction in the development of advanced light-harvesting porous organic polymer nanocomposite materials, showing potential applications in designing smart protective coatings against chemical warfare agents under natural sunlight conditions.

Composite Material

This composite material has integrated near-infrared absorbing upconversion nanoparticles and visible light absorbing gold nanoparticles with a UV rays absorbing conjugated porous organic polymer (POP), say IISER Bhopal researchers.

The use of upconversion and gold nanoparticles enhances the chemical reaction so drastically, say sources from IISER Bhopal.

Technical aspects

Speaking on the technical aspects of this research, Prof. Abhijit Patra said they have developed an innovative design approach that involves the integration of plasmonic and upconversion nanoparticles with a conjugated porous organic polymer, which opens up new vistas towards artificial light harvesting.

Applicability

To test the applicability of this photocatalyst, the research team coated a small piece of cotton cloth with the UC-POP-Au under direct sunlight to detoxify mustard gas simulant, a popular chemical warfare agent, say sources from IISER Bhopal.

Displaying excellent performance compared to a regular polymer-based photocatalyst, the UC-POP-Au significantly expedited photocatalysis, say sources from IISER Bhopal.

Explored

The detoxification of chemical warfare agents is currently being explored all over the world. And with photocatalysts such as UC-POP-Au, that process can now become faster.

The research team suggests that the developed photocatalyst UC-POP-Au can be used for creating personal protective equipment and also has high application potential as promising materials for various other industries beyond the detoxification of chemical warfare agents.

The research team from IISER Bhopal is now further expanding the scope of their work in developing advanced materials for harnessing light energy to break down other toxic chemicals.

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.

1. The URL has to be typed into the browser and the webpage has to be allowed to download.

2. Once the website is available, students should click the link for JEE Advanced AAT 2025 registration and enter JEE Advanced 2025 registration number, their date of birth, mobile number and email address.

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:

Geometrical Drawing

Exercises in geometrical drawing containing lines, angles, triangles, quadrilaterals, polygons, circles, etc. Study of plan (top view), elevation (front or side views) of simple solid objects like prisms, cones, cylinders, cubes, splayed surface holders, etc.

Freehand Drawing

This would comprise of simple drawing depicting the total object in its right form and proportion, surface texture, relative location and details of its component parts in appropriate scale.

Common domestic or day-to-day life usable objects like furniture, equipment, etc., from memory.

Three dimension perception

Understanding and appreciation of three-dimensional forms with building elements, colour, volume and orientation. Visualization through structuring objects in memory.
