Summary: In this study, multinary, heterostructured and octahedral nanoshells with adjustable structures were synthesized. The synthesis process involved widely used post-synthetic modifications including galvanic replacement, facet selective growth and etching, as well as cation exchange reactions. The resulting complex, hollow, metal-semiconductor hybrid particles demonstrated modularity of constituent reactions and potential for even more diverse and complex structures through retrosynthetic design.

Summary: In this study, CuSexS1-x nanocrystals were synthesized using a computation-driven approach to modulate their optical bandgap energy by tuning the composition. The experimental results showed qualitative agreement with predicted material properties, with quantitative deviations likely resulting from unaccounted for interfacial and morphological characteristics in DFT models.

Summary: In this study, fig leaves were used as materials to efficiently extract and enrich psoralen (PSO) using a strong acidic cation exchange resin transformation method (SACERTM) combined with macroporous adsorption resin (MAR). The optimized extraction conditions yielded a high PSO yield of 36.74 mg/g, with a conversion efficiency of psoralenglucoside (PO) to PSO reaching 70.41% using D072 resin as a catalyst. After enrichment using MAR, the purity of PSO increased by 24.8-fold. This study demonstrates the effectiveness of SACERTM combined with MAR purification for extracting and enriching PSO from fig leaves.

Summary: In this study, rod-shell nanostructures (CdS/Cu2S) were constructed by growing Cu2S as the outer shell on CdS nanorods, resulting in significantly enhanced hydrogen production activity. The improved photocatalytic performance of CdS/Cu2S rod-shell nanostructures is attributed to the structural design facilitating electron transfer and the broadened light absorption range achieved by Cu2S outer shells. This work provides insight into the design of rod-shell structured photocatalysts for efficient solar energy conversion.

Summary: For the first time, a series of colorful binary and ternary core-shell composite crystals were successfully designed and prepared through the epitaxial growth method. These crystals, representative of hierarchical crystalline species, were synthesized from functional magnetic polynuclear clusters phases. The composition and structure of the synthesized composites were characterized, and their magnetic properties were investigated.

Summary: This study evaluated the pre-concentration and fractionation of rare earth elements (REE) from acid mine drainage using ion exchange technique. The results showed that the ion exchange resin exhibited higher selectivity for La, Ce, Pr and Nd during the loading step, while 0.01mol L-1 NH4EDTA achieved better elution profiles during the fractionation step.

Summary: Elaborate chemical synthesis methods allow the production of inorganic nanocrystals with uniform shape and size distributions. Ion exchange reactions for ionic nanocrystals have been extensively studied due to the large surface-to-volume ratio of the nanoparticles. The cation exchange reactions proceed much faster than anion exchange reactions due to the larger ionic radii of anions within the frameworks of nanocrystals.

Summary: The study proposed a rod-coil grafts design to enhance microphase separation in N-spirocyclic anion exchange membranes, resulting in improved conductivity and toughness. By optimizing the n-octylamine hydrophobic coil graft length, the N-spirocyclic AEM showed high OH- conductivity and power density, placing it among the top level of cycloaliphatic AEMs reported in literature.

Summary: Oriented synthesis of transition metal sulfides (TMSs) with controlled compositions and crystal structures has been achieved through gas-phase cation exchange (GCE), allowing for the synthesis of versatile TMSs with identified cubic or hexagonal crystal structures. The substitution of cations and the transition of the anion sublattice are described using a new descriptor called parallel six-sided subunit (PSS), enabling the tailoring of band gaps in targeted TMSs. The photocatalytic hydrogen evolution rate of zinc-cadmium sulfide (ZCS4) is determined to be 11.59 mmol h(-1) g(-1), showing a 36.2-fold improvement over CdS.

Summary: Plasmonics, particularly localized surface plasmon resonance (LSPR) in non-noble metal bismuth nanoparticles (Bi NPs), and their spectral properties have garnered research interest. The study successfully synthesized size-tunable spherical Bi NPs through a thiolate pyrolysis reaction, allowing for precise control of diameters ranging from 65 to 205 nm. The size-dependent LSPR optical properties of Bi NPs showed rich UV-visible-near-infrared spectral responses, with complete oxidation leading to the formation of metastable tetragonal-phase beta-Bi2O3 NPs and interesting polymorphic transitions.

Summary: Etching anisotropy is a common phenomenon used in chemical etching to create micro/nanostructures with specific shapes and properties. In this study, we demonstrate the anisotropy in wet etching of 2D tin monosulfide microflakes. The use of a thiol-amine mixture solvent as the etchant enables the preferential etching of specific surfaces and vertices of the microflakes, resulting in the transformation of their shape. This work opens up possibilities for tailoring the size, shape, and crystal surface of inorganic-nonmetallic chalcogenides using etching chemistry.

Summary: Single-crystal XRD crystallography reveals a new class of vdWs molecular crystals with a lamellar structure formed by the self-assembly of long alkyl chains. They possess a nearly planar and rigid molecular geometry resulting from the presence of trans and gauche S-C bonds, and exhibit a variety of physicochemical properties dependent on chain length.

Summary: In this study, Ag2Se seeds were utilized as catalyst particles to successfully grow metal selenide NWs on metal substrates. The metal foil or flakes served as both a support substrate and a source of metal cations during the NW synthesis process. Microstructural studies revealed the polytypism and diameter-dependence of crystal phases and growth directions in the resulting NWs.
