Recyclability and recovery of carbon from waste printed circuit boards within a circular economy perspective: A review.

Waste printed circuit boards (WPCBs) are a significant component of electronic waste (e-waste) and are among the fastest-generating waste flows. The potentially negative impacts caused by e-waste on the environment and human health pose an increasingly apparent threat to people's everyday lives and well-being. The nonmetallic fraction (predominantly carbon) of WPCBs is characterized by heavy weight, low resource value, and complex composition, and these characteristics significantly restrict the recycling of the WPCBs to achieve a circular economy.

Non-contrast magnetic resonance imaging versus ultrasonography for hepatocellular carcinoma surveillance: A randomized, single-center trial.

Background & Aims: This study aimed to compare ultrasonography (US) and non-contrast magnetic resonance imaging (MRI) in the surveillance of hepatic malignancy.

Methods: We conducted a randomized, non-blinded, single-center trial at a single center in South Korea. Eligible individuals were aged 20-70 years with liver cirrhosis, Child-Pugh class A, and no history of liver cancer or other recent malignancy.

Deep eutectic solvent-assisted recycling of spent lithium-ion batteries into electrocatalysts for polyethylene terephthalate upcycling.

We propose an effective method for selectively extracting the valuable metals from the spent LiNiCoMnO cathode material using an oxalic acid-based deep eutectic solvent. Through regulation of the coordination environment, NiO, CoO, and MnO are stepwise separated and further applied in the electrochemical conversion of raw PET bottles to high-purity formic acid.

Chromosome-level genome assembly and annotation of Japanese anchovy (Engraulis japonicus).

The Japanese anchovy (Engraulis japonicus), a finfish with the largest biomass of a single species in the Yellow and East China Seas, plays an important pivotal role in converting zooplanktons into high trophic fish in the food web. As a result, the fish is regard as a key species in its habiting ecosystem. However, the lack of genomic resources hampers our understanding of its genetic diversity and differentiation, as well as the evolutionary dynamics.

Genetic deficiency or pharmacological inhibition of cGAS-STING signalling suppresses kidney inflammation and fibrosis.

Background And Purpose: Chronic kidney disease (CKD) is characterised by inflammation, which can lead to tubular atrophy and fibrosis. The molecular mechanisms are not well understood. In this study, we investigated the functional role of the cyclic GMP-AMP synthase (cGAS)- stimulator of interferon genes (STING) signalling in renal inflammation and fibrosis.
