A two-dimensional fluorescence and chemiluminescence orthogonal probe for discriminating and quantifying similar proteins.

Given that proteins with minor variations in amino acid sequences cause distinct functional outcomes, identifying and quantifying similar proteins is crucial, but remains a long-standing challenge. Herein, we present a two-dimensional orthogonal fluorescence and chemiluminescence design strategy for the probe DCM-SA, which is sequentially activated by albumin-mediated hydrolysis, exhibiting light-up fluorescence and photo-induced cycloaddition generating chemiluminescence, enabling orthogonal signal amplification for discrimination of subtle differences between similar proteins. By orthogonalizing these dual-mode signals, a two-dimensional work curve of fluorescence and chemiluminescence is established to distinguish and quantify similar proteins HSA and BSA.

Mechanism of solid electrolyte interphase film formation using ethylene carbonate-based local high concentration electrolyte in sodium-ion batteries.

Sodium-ion batteries (SIBs) have the advantages of abundant resources and low cost, making them potential candidates for the next-generation large-scale energy storage technology. However, the capacity fade during cycling used in sodium-ion batteries is a major challenge. The rational design of the electrolyte is one of the ways to solve these problems.

Iodine staining with distance countdown improving the safety for reduction of adverse events: a randomized controlled trial.

Background: Lugol's chromoendoscopy (LCE) is valuable, cost-effective, and widely used in early esophageal cancer (EEC) screening, yet it suffers from low compliance due to adverse events after LCE. In addition, the reflux of iodine during iodine staining in the upper esophagus brings the risk of bucking and aspiration. We introduced a new model called distance countdown (DC) aimed to reduce reflux during iodine staining in upper esophageal LCE.

Epitaxial Electrodeposition of Zinc on Different Single Crystal Copper Substrates for High Performance Aqueous Batteries.

The aqueous zinc metal battery holds great potential for large-scale energy storage due to its safety, low cost, and high theoretical capacity. However, challenges such as corrosion and dendritic growth necessitate controlled zinc deposition. This study employs epitaxy to achieve large-area, dense, and ultraflat zinc plating on textured copper foil.

Differential activation of defense responses in cucumbers by adapted versus non-adapted lineages of the cotton-melon aphid.

Background: The cotton-melon aphid, Aphis gossypii Glover, is a polyphagous pest damaging plants across over 100 families. It has multiple host-specialized lineages, including one colonizing Malvaceae (MA) and one colonizing Cucurbitaceae (CU). The mechanisms underlying these host relationships remain unknown.
