Zhang, M. (author), Raghunath, Aparna (author), Zhao, A. (author), Eral, H.B. (author)On-dose authentication (ODA) enhances security by incorporating customized molecular or micro-tags into each pill, preventing counterfeit products in genuine packages. ODA's security relies on tag non-replication and non-reverse engineering. Combining ODA with graphical Physical Unclonable Functions (PUF) promises maximum security. PUF uses...journal article 2024

Kamis, Y.E. (author), Prakash, Suriya (author), Breugem, W.P. (author), Eral, H.B. (author)We experimentally and numerically study the dynamics of a liquid jet issued from a rotating orifice, whose breakup is regulated by a vibrating piezo element.

Zhang, M. (author), Arunachalam, Abinaya (author), Perrin, H.R.L. (author), Polat, S. (author), Groenewold, Jan (author), Mendes, E. (author), Eral, H.B. (author)Elevated humidity levels in medical, food, and pharmaceutical products may reduce the products' shelf life, trigger bacterial growth, and even lead to complete spoilage. In this study, we report a humidity indicator that mechanically bends and rolls itself irreversibly upon exposure to high humidity conditions. The indicator is made of two...journal article 2023

(author)Crystallization abounds in nature and industrial practice. A plethora of indispensable products ranging from agrochemicals and pharmaceuticals to battery materials are produced in crystalline form in industrial practice. Yet, our control over the crystallization process across scales, from molecular to macroscopic, is far from complete. This...review 2023

(author), van der Veen, M.A. (author)Large amounts of carbon monoxide are produced by industrial processes such as biomass gasification and steel manufacturing. The CO present in vent streams is often burnt, this produces a large amount of CO<sub>2</sub>, e.g., oxidation of CO from metallurgic flue gasses is solely responsible for 2.7% of manmade CO<sub>2</sub> emissions. The...review 2023
