Differential rates of water loss were achieved in picked avocado (Persea americana Mill.) fruits, either by controlling the evaporation rate or by supplying water through the fruit stalk. A negative linear correlation was found between the daily rate of water loss from fruits and their ripening, as determined by the time from harvest to peak of ethylene production. Ripening rate was hastened by 40% in fruits which had lost water at rate of 2.9% fresh weight per day, compared with those which lost only 0.5% per day.

In this study, thiolated sodium alginate (SA) and hydrophilic, polymerizable Janus-type polyhedral oligomeric silsesquioxane (AS-POSS) are synthesized by introducing thiol and sulfonic acid groups, respectively. A series of pH-responsive SA/PEGDA/AS-POSS nanocomposite hydrogels are successfully prepared through Michael addition reactions between the thiol groups of thiolated sodium alginate and the double bonds in the molecular chains of AS-POSS and poly(ethylene glycol) diacrylate (PEGDA). This reaction proceeds rapidly under physiological conditions without requiring initiators or catalysts.

Poly(ethylene oxide) (PEO)-based solid composite electrolytes suffer from poor conductivity and lithium dendrite growth, especially toward the metallic lithium metal anode. In this study, succinonitrile (SN) is incorporated into a PEO composite electrolyte to fabricate an electrode-compatible electrolyte with good electrochemical performance. The SN-doped electrolyte successfully inhibits the lithium dendrite growth and facilitates the SEI layer formation, as determined by the operando nanofocus wide-angle X-ray scattering (nWAXS), meanwhile, stably cycled over 500 h in Li/SN-PEO/Li cell.

Potassium-ion batteries (KIBs) have emerged as promising candidates for low-cost, high-energy storage systems, driven by their fast ionic conductivity and high operating voltage. To develop advanced KIBs, the performance is usually evaluated in half-cell tests using highly reactive potassium metal, which often leads to misinterpretation of the results due to degradation processes between metal anode and electrolyte components. Here, we systematically investigated the surface reactivity of potassium metal, which is in contact with commonly used solvent combinations, namely, mixtures of ethylene carbonate and linear bis(alkyl)carbonates.

Lung progenitor (LP) cells identified by the expression of transcription factor NK2 homeobox 1 (NKX2.1) are essential for development of all lung epithelial cell types and hold tremendous potential for pulmonary research and translational regenerative medicine applications. Here we present engineered hydrogels as a promising alternative to the naturally derived materials that are often used to differentiate human induced pluripotent stem cells (iPSCs) into LP cells.
