Upcycle Your [PDF]

Proceedings of the 22nd Conference on Computational Natural Language Learning, 2018
We propose a post-OCR text correction approach for digitising texts in Romanised Sanskrit.Owing to the lack of resources our approach uses OCR models trained for other languages written in Roman.Currently, there exists no dataset available for Romanised Sanskrit OCR.So, we bootstrap a dataset of 430 images, scanned in two different settings and their ...

Polymeric Sorbents as Energy‐Efficient Alternative to Cryogenic Distillation for Light Hydrocarbon Purification

Advanced Materials, EarlyView.
The transition from cryogenic distillation to polymeric sorbents for light hydrocarbon purification is crucial for energy and environmental sustainability. The polymeric sorbents are engineered to separate gas mixtures based on their specific properties.

A Tert‐Alkyl Terephthalate Derivative as a Universal Degradable Unit for Condensation Polymers

Angewandte Chemie, EarlyView.
A sterically bulky dicarboxylic acid core bearing a tertiary alkyl ester enables photocatalytic C─O bond cleavage via generation of a stabilized tertiary alkyl radical. Incorporated into polyarylate, polyurethane, and polyester, this universal trigger facilitates efficient degradation under identical conditions (up to 99% within 2–4 h). Remarkably, the

Photocatalytic upcycling of polylactic acid to alanine by sulfur vacancy-rich cadmium sulfide

Nature Communications
Photocatalytic conversion has emerged as a promising strategy for harnessing renewable solar energy in the valorization of plastic waste. However, research on the photocatalytic transformation of plastics into valuable nitrogen-containing chemicals ...

Defect‐Engineered Microwave‐Responsive Ni@C Composites From Waste PET for Catalytic Plastic Upcycling

Advanced Materials, EarlyView.
A circular upcycling strategy transforms waste poly(ethylene terephthalate) bottles into microwave‐responsive Ni@C catalyst featuring lattice‐distorted nickel cores and defective carbon shells. These strain‐rich heterointerfaces enhance dielectric loss and promote localized microwave hotspots, accelerating peroxymonosulfate activation and polymer‐chain

On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy

Angewandte Chemie, EarlyView.
Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).

Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2

Advanced Science, EarlyView.
Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen

UNPARK. The second life of an infrastructure in a high-density urban environment

Agathón, 2021
The UNPark research project moves within the boundaries of urban mining, applying the idea of ‘wasted architecture’ to be salvaged and repurposed for urban infrastructures, thus ‘reclaiming public space’ where it was not previously possible.
