Abstract

This experiment was conducted to formulate a water-based ink with antimicrobial properties for packaging applications. Two distinct types of inks were developed, one with synthetic yellow color pigment and the other with curcumin, as an antimicrobial and a natural yellow pigment. The resulting two inks were then printed on polyethylene terephthalate (PET) films, and the physiochemical characteristics of the ink were thoroughly examined. The coated inks had an average thickness of 10 microns for both the inks. The viscosity of the water-based ink and the antimicrobial water-based ink were determined to be 54cp and 30cp, respectively and the drying time of the inks was 10 sec. At the same time, the gloss value increased from 30% to 50% in the case of antimicrobial ink. The antimicrobial efficacy of the antimicrobial water-based ink, as demonstrated against S. aureus and E. coli, surpassed that of the conventional water-based ink. These findings showed that the antimicrobial water-based ink had a good drying time, increased gloss, and favorable storage stability. Using curcumin as a pigment in water-based ink may be significant for printing applications of active food packaging materials. It can also help lower the risk of contamination of the food components with microbes.

Abstract

With the rapid advancement of healthcare services into cloud-based platforms, ensuring the security of patient data and healthcare transactions has become paramount. The need for this work stems from the continuously evolving cyber threats that jeopardize patient privacy and the integrity of medical data. Existing security models in cloud-based healthcare systems, ranging from traditional encryption techniques to role-based access controls, offer varying degrees of protection. However, their efficacy in the face of contemporary challenges remains questionable. In this paper, we present an in-depth review of emerging security techniques, where the objectives are to specifically focusing on blockchains, Physical Unclonable Functions (PuFs), and machine learning-based security measures. Our review methodology's contribution is that it offers a comparative analysis based on real-time performance measures, thereby aiding stakeholders in discerning the most apt models for their specific functional and performance-centric requirements. The insights from this work are pivotal not only for advancing the resilience of cloud-based healthcare systems against cyber threats but also for fostering trust amongst users. By delineating the strengths and weaknesses of contemporary security mechanisms, our review paves the way for the development of more robust, efficient, and scalable security models for the future of digital healthcare.

Abstract

Semi‐transparent perovskite solar cells (ST‐PSCs) are promising for their application in building integrated photovoltaics (BIPVs). For BIPVs, a light utilization efficiency (LUE) > 2.5 is required which is multiplication of average visible transmittance (AVT) and power conversion efficiency (PCE). Generally, semitransparency is achieved by reducing film thickness which increases AVT but decreases PCE resulting in lower LUE. Here, an interface engineering strategy is employed on a wide bandgap perovskite thin absorber layer to increase PCE and LUE. The study employs three different alkylamine hydrochlorides molecules with varied alkyl chain length, viz., 2‐chloroethylamine‐hydrochloride, 3‐chloropropylamine‐hydrochloride, and 4‐chlorobutyalamine‐hydrochloride at perovskite/electron transport layer (ETL) interface and investigates their effect on perovskite crystallization. Further, it is demonstrated that 4‐chlorobutyalamine‐hydrochloride can strongly interact with perovskite and suppress non‐radiative recombination facilitating charge transport at the perovskite/ETL interface. Devices post‐treated with 4‐chlorobutyalamine‐hydrochloride interfacial layer, demonstrate a higher LUE of 3.45% (PCE 14.11%) and AVT of ≈25% (400–800 nm), with Voc of 1.23 V. Moreover, the unencapsulated devices retain ≈89% of the initial efficiency after storage for 1500 h under a relative humidity of ≈35–40%. This study provides an efficient approach to improve LUE and stability of ST‐PSCs for the application in energy‐efficient smart windows. [ABSTRACT FROM AUTHOR]
