Flavoured drinks without sugar can be perceived as sweet – and now researchers know why. A new study from Karolinska Institutet in Sweden, published in the journal Nature Communications, reveals that the brain interprets certain aromas as taste.
Researchers outline a path to turn carbon dioxide into a valuable green fuel and chemical feedstock, offering a promising strategy for a circular carbon economy.
As the world faces the urgent challenges of climate change and the transition to sustainable energy, a new critical review provides a comprehensive roadmap for converting waste carbon dioxide (CO2) and carbon monoxide (CO) into propanol, a valuable fuel and industrial chemical. Published by researchers from Korea University and the Korea Institute of Science and Technology (KIST), the review highlights innovative strategies and outlines future directions for efficient, scalable production of propanol, a vital alcohol used in fuels, chemicals, and pharmaceuticals.
Researchers have created a novel, bio-based foam that integrates three advanced functions: shielding electromagnetic interference, regulating temperature, and reducing infrared visibility. This lightweight, durable material could protect sensitive electronics in electromagnetic and thermal shock and offer new solutions for camouflage technology.
In a paper published in MedComm – Biomaterials and Applications, a research team from Guangzhou Medical University reports the development of a copper ion (Cu²⁺)-coordinated nanoplatform (designated as CuN) using the indoleamine 2,3-dioxygenase-1 (IDO1) inhibitor NLG919. This carrier-free nanoplatform can efficiently encapsulate various chemotherapeutic agents (e.g., cinnamic acid, mitoxantrone, docetaxel, β-lapachone) and activate systemic antitumor immunity by inducing immunogenic cell death (ICD) and inhibiting IDO1. Using β-lapachone-loaded CuN (Lap@CuN) as a representative, the team demonstrated robust suppression of primary tumor growth and lung metastasis in mice without obvious side effects, offering a new strategy for synergistic chemo-immunotherapy.
Scalable fabrication of efficient wide-bandgap (WBG) perovskite solar cells (PSCs) is crucial to realize the full commercial potential of tandem solar cells. However, there are challenges in fabricating efficient methylammonium-free (MA-free) WBG PSCs by blade coating, especially its phase separation and films stability. In this work, an MA-free WBG perovskite ink is developed for preparing FA0.8Cs0.2Pb(I0.75Br0.25)3 films by blade coating in ambient air. Among various A-site iodides, RbI is found to be the most effective in suppressing the precipitation of PbI2 induced by Pb(SCN)2 while keeping the enlarged grains. The distribution of Rb suggested that the Rb ions are kept isolated with the perovskite grains during the crystallization and Ostwald ripening processes, which contributes to the formation of the large-grain WBG perovskite film with minimum non-radiative recombination. As a result, a power conversion efficiency (PCE) of 23.0% was achieved on small-area WBG PSCs, while mini-modules with an aperture area of 10.5 cm2 exhibited a PCE of 20.2%, among the highest reported for solar cells prepared with WBG perovskites via blade coating. This work presents a scalable and reproducible fabrication strategy for stable MA-free WBG PSCs under ambient conditions, advancing their path toward commercialization.
Refractory wounds cause significant harm to the health of patients and the most common treatments in clinical practice are surgical debridement and wound dressings. However, certain challenges, including surgical difficulty, lengthy recovery times, and a high recurrence rate persist. Conductive hydrogel dressings with combined monitoring and therapeutic properties have strong advantages in promoting wound healing due to the stimulation of endogenous current on wounds and are the focus of recent advancements. Therefore, this review introduces the mechanism of conductive hydrogel used for wound monitoring and healing, the materials selection of conductive hydrogel dressings used for wound monitoring, focuses on the conductive hydrogel sensor to monitor the output categories of wound status signals, proving invaluable for non-invasive, real-time evaluation of wound condition to encourage wound healing. Notably, the research of artificial intelligence (AI) model based on sensor derived data to predict the wound healing state, AI makes use of this abundant data set to forecast and optimize the trajectory of tissue regeneration and assess the stage of wound healing. Finally, refractory wounds including pressure ulcers, diabetes ulcers and articular wounds, and the corresponding wound monitoring and healing process are discussed in detail. This manuscript supports the growth of clinically linked disciplines and offers motivation to researchers working in the multidisciplinary field of conductive hydrogel dressings.
In a pioneering study that combines advanced technology with agricultural practices, researchers are exploring how capacitance-enhanced biochars can significantly increase the removal of ginsenoside Rb1 from soils. The study, titled "Increased Removal of Ginsenoside Rb1 Through the Application of Capacitance-Enhanced Biochars in Soils," is led by Prof. Bo Pan from the Yunnan Provincial Key Lab of Soil Carbon Sequestration and Pollution Control at Kunming University of Science & Technology in Kunming, Yunnan, China. This research offers valuable insights into sustainable soil management and the potential of biochars in addressing soil contamination.
