The diversity of water pH values is a key factor that restricts the practical application of photocatalytic water purification. The construction of liquid (water)–liquid (oil)–solid (semiconductor) (L–L–S) triphase interface microenvironment makes the organic molecule adsorption pH independent and prevents the semiconductor from being corroded by strong acidic/alkaline solutions, leading to a stable and efficient photocatalytic reaction over a wide pH range (1–14). These findings reveal a promising path for the development of high‐performance catalysis systems applicable in complex water environments.

A chemical investigation of the deep‐sea‐derived fungus Penicillium allii‐sativi resulted in the discovery of four new (1—4) and one known (5) meroterpenoids. Compound 3 significantly blocked the mTOR signaling pathway, resulting in the arrest of cell cycle at G0‐G1 phase and triggering mitochondrial apoptosis in Hela cells. While macrophorin A effectively triggered cell death in MDA‐MB‐231 cancer cells by activating apoptosis pathways involving death receptors, mitochondria, mTOR, and TNF. More details are discussed in the article by Yang et al. on pages 3283—3292. image

AN IMAGE ENCRYPTION METHOD BASED ON LOGISTICAL CHAOTIC MAPS TO ENCRYPT COMMUNICATION DATA

Encryption is crucial because of how integral to daily life things like smartphones, computers, and the internet have become. It's almost inconceivable to think about getting by without it. Everything from paying bills and buying goods to email and social networking is done online nowadays. Participating in measures that can prevent illegal access to our accounts, data, and devices is more crucial than ever. In this study, we combined a 256-by-256-pixel cover picture with a 128-by-128-pixel inner image using the logistic map (the chaotic function), where both images were in the PNG format. where the encrypted image is converted to a grayscale image and then encrypted through the logistic function. the output of this process is chaotic data that has been converted into binary data to be encrypted again through the colors of the cover image (red, green and blue) each separately and measuring the standard factors to know the strength of the system. The bit error rate was calculated after measuring the signal-to-noise ratio (SNR), system similarity(SSIM), and Peak Signal to Noise Ratio(PSNR) for these three hues. Using the logistic map, all three colors were found to be equally secure during encryption in the chaotic signal and due to unpredictability.

AbstractThe European Steel Bridge Awards are given by ECCS every two years to encourage the creative and outstanding use of steel in construction of bridges. Among 16 projects received from all over Europe, a winner per category was selected by the expert jury and awarded during the 2024 ESBA Ceremony on 12 September 2024 in Prague. In the category Road and Railway Bridges the “U81 Brücke Nordstern in Düsseldorf/Germany”, submitted by Austria (© MCE GmbH), was awarded. More information regarding the awarded projects are in the ECCS News, p. 242.
