Summary: A novel colorimetric/fluorescent probe (AgNPs-GSH-Rh6G2) was prepared by linking silver nanoparticles (AgNPs) with rhodamine 6G derivative (Rh6G2) using glutathione (GSH) as a linker molecule. The probe exhibited significant fluorescence change and colorimetric response upon addition of copper ions. A colorimetric/fluorescence dual-mode detection method was developed based on this phenomenon to selectively detect copper ions. The probe showed good sensitivity with linear ranges of 0.10-0.45 mM for fluorescence detection and 0.15-0.65 mM for colorimetric detection, and the detection limits were 0.18 μM and 24.90 μM, respectively. The dual-mode probe also demonstrated satisfactory results in detecting copper ions in sediment samples.

Summary: Dodecamer duplex DNA containing anomeric and enantiomeric mismatches were studied for base pair stability with silver ions present. The study found that stable duplexes were formed with silver-mediated cytosine-cytosine pairs, with stability changes depending on the composition of the mismatches. Notably, a new silver-mediated base pair was found to be superior in stability compared to a well-known pair.

Summary: The study found that the proton yield on Si(111)7 x 7 and Si(100)2 x 1 surfaces increases over time when irradiated with slow, highly charged xenon ions. The proton yield on the Si(100)2 x 1 surface is related to HCI irradiation time and temporal variation of H2O coverage. The proton desorption efficiency is highest with Xe50+ compared to Xe29+ and Xe44+.

The FeNi LDH nanosheets grow from the mesopores of SOMC and wrap the SOMC, achieving mechanical fixation and electron transfer between the two materials. The FeNi LDHs@SOMC exhibits low overpotential and excellent corrosion resistance in alkaline environments.

Summary: By replacing the H2O ligands with polyoxometalate (POM) [H2W12O40](6-) {W12O40} pro-ligands, a novel nano porous 2D network {[Cu-2(OAc)(4)](2)(W12O40)}(n) was synthesized. The compound exhibited high efficiency as a homogeneous catalyst in the homo-coupling of terminal alkynes under mild conditions and low amounts. In situ DRIFTS results revealed the changes of alkyne substances during the catalytic process, while XPS results showed electron transfer from {W12O40} to Cu(ii) to promote the C-H activation step. A synergistic Cu(ii)-POM catalytic mechanism was proposed.

Summary: CdE (E = S, Se) quantum dots (QDs) with broad and large Stokes shift PL emission have potential applications in white-light LEDs. However, the current limitation is the low quantum efficiency of the surface-related emission of nanocrystals. In this study, a convenient non-injected one-pot method at a relatively low temperature was used to prepare CdS QDs. The CdS-368 QD exhibits intense broad yellow emission in solution and the solid state at room temperature. The coligation of organic and inorganic ligands passivates the electron trap states at the QD surface, leading to high stability of colloids in organic solvents and an enhanced fluorescence quantum yield.

Summary: Historically, electrochemistry has been important in the machinery processing industry, particularly for difficult-to-machine materials and profiled structures. However, there is a current challenge for electrochemical machining to meet the requirements of micro-/nanomanufacturing. The Confined Etchant Layer Technique (CELT) has been proposed as a promising solution for fabricating three-dimensional micro-/nanostructures and polishing supersmooth surfaces.

Summary: This paper investigates a pure 2D inorganic POM-based framework that undergoes a single crystal to single crystal conversion when soaked in organic solvents miscible to water, resulting in a more densely packed identical framework and the formation of nanowires. The change in morphology is closely linked to the surface tension of water, with lower surface tension achieved through dehydration promoting the formation of nanowires, as revealed through SXRD, PXRD, SEM, TGA, and EIS.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
