Template* Synthesize

Three-dimensionally (3D) integrated metallic nanomaterials composed of two or more different types of nanostructures make up a class of advanced materials due to the multidimensional and synergistic effects between different components. However, designing and synthesizing intricate, well-defined metallic 3D nanomaterials remain great challenges. Here, a novel single-particle soft-enveloping strategy using a core-shell Au NP@mSiO2 particle as a template was proposed to synthesize 3D nanomaterials, namely, a Au nanoparticle@center-radial nanorod-Au-Pt nanoparticle (Au NP@NR-NP-Pt NP) superstructure...

While metal-mediated self-assembly is a popular technique to construct discrete nanosized objects, highly symmetric structures, built from one type of ligand at a time, are dominating reported systems. The tailored integration of a set of different ligands requires sophisticated approaches to avoid narcissistic separation or formation of statistical mixtures. Here, we demonstrate how the combination of three structure-guiding effects (metal-templated macrocyclization, additional bridging ligands and shape-complementarity) based on Co(III)salphen metal nodes allows for a rational and high-yielding synthesis of structurally complex, lantern-shaped cages with up to four differentiable bridges...

Two templated borates, [Co(1-EI)2 ]·[B5 O7 (OH)3 ] (1) and [Ga(1-MI)2 ·B6 O9 (OH)4 ]·[H3 BO3 ]·H[1-MI] (2), have been synthesized using a mild method. Notably, they exhibit an excellent ORR performance with an E 1/2 value of 0.84 V and are the first to be used as the positive electrode catalyst for a zinc-air battery, which opens a pathway for the application of borate-based oxide catalysts.

Nickel foam modified by hollow sphere NiCo2 O4 particles was successfully prepared via a hydrothermal method using nanosphere SiO2 particles as the hard template for the hollow structure. Characterisation using SEM-EDX and TEM confirmed the structure as multiwalled hollow spheres with an average size of 270 nm, while characterisation using SEM, XRD, and XPS confirmed that the NiCo2 O4 particles were attached on the surface of the nickel foam. BET analysis showed that the surface area of the synthesized NiCo2 O4 @Ni foam was nearly three times higher compared to that of the unmodified Ni foam...

Photocatalytic H2 production with selective oxidation of organic moieties in an aqueous medium is a fascinating research area. However, the rational design of photocatalysts and their photocatalytic performance are still inadequate. In this work, we efficiently synthesized the MoS2 tipped CdS nanowires (NWs) photocatalyst using soft templates via the two-step hydrothermal method for efficient H2 production with selective oxidation of benzyl alcohol (BO) under visible light illumination. The optimized MoS2 tipped CdS NWs (20 % MoS2 ) photocatalyst exhibits the highest photocatalytic H2 production efficiency of 13...

The detection of hazardous CO gas is an important research content in the domain of the Internet of Things (IoT). Herein, we introduced a facile metal-organic frameworks (MOFs)-templated strategy to synthesize Cd-doped Co3 O4 nanosheets (Cd-Co3 O4 NSs) aimed at boosting the CO-sensing performance. The synthesized Cd-Co3 O4 NSs feature a multihole nanomeshes structure and a large specific surface area (106.579 m2 ·g-1 ), which endows the sensing materials with favorable gas diffusion and interaction ability...

A novel method for synthesizing cationic styryl dyes through a nucleic acid-templated reaction has been developed. This approach overcomes issues associated with traditional synthesis methods, such as harsh conditions, low throughput, and wasteful chemicals. The presence of a nucleic acid template accelerated the styryl dye formation from quaternized heteroaromatic and cationic aldehyde substrates. These styryl dyes show remarkable optical properties change when bound to nucleic acids, hence the success of the synthesis could be readily monitored in situ by UV-Vis and fluorescence spectroscopy and the optical properties data were also observable at the same time...

The controlled synthesis of mesoporous metal oxides remains a great challenge because the uncontrolled assembly process and high-temperature crystallization can easily destroy the mesostructure. Herein, we develop a facile, versatile, low-cost, and controllable molten salt assisted assembly strategy to synthesize mesoporous metal oxides (e.g., CeO2 , ZrO2 , SnO2 , Li2 TiO3 ) with high surface area (115-155 m2 /g) and uniform mesopore size (3.0 nm). We find this molten salt mediated assembly enables the desolvation of the precursors and forms bare metal ions, enhances their coordination interaction with the surfactant, and promotes their assembly into a mesostructure...

Chitosan, an abundant natural polysaccharide, was conjugated with carbon dots (CDs) and self-polymerized with chloramphenicol (CAP) templates to synthesize CD-incorporated and molecularly CAP-imprinted polychitosan (CD-MIC). The CD-MIC was used for fluorescent sensing, dispersive sorption, and dosage release of CAP at different pH levels. The sphere of action mechanism, approved by emission and excitation fluorescence, UV-Vis absorption, and fluorescence lifetime measurements, regulated the fluorescence static quenching...

In electro-Fenton (EF), development of a bifunctional electrocatalyst to realize simultaneous H2 O2 generation and activation efficiently for generating reactive species remains a challenge. In particular, a nonradical-mediated EF is more favorable for actual wastewater remediation, and deserves more attention. In this study, three-dimensional graphene loaded with Fe3 O4 nanoparticles (Fe3 O4 @3D-GNs) with abundant oxygen-containing functional groups (OFGs) was synchronously synthesized using a NaCl-template method and served as a cathode to establish a highly efficient and selective EF process for contaminant degradation...

Genome-walking is a molecular tool used to unveil uncharacterized DNA regions flanking a known DNA, which has been widely used in bioscience and related areas. This study developed a reliable and efficient PCR-based genome-walking approach, named as single primer site-specific nested PCR (SPN-PCR). A SPN-PCR set sequentially consists of three single-primer nested PCR amplifications. The primary relaxed thermal cycle promotes outmost nested site-specific primer (NSSP) to partially combine with numerous places on DNA template, synthesizing many single-stranded DNAs (ssDNA)...

Metal-organic frameworks (MOFs) are self-assembled constitutive precursors and efficient self-sacrificial templates with metal ions/clusters and organic linkers from which multifunctional materials with carbon nanostructures can be derived. In this study, we synthesized a novel Cu-MOF with Cu(II) as the central metal ion through two ligands, N , N '-bis(pyridin-3-yl)terephthalamide (3-bpta) and fumaric acid (H2 FA), which was used as a template for derivatizing carbon-based nanostructured materials of Cu and Cu x O through doping with different materials (melamine, urea, and TiO2 ) in a simple and efficient one-step pyrolysis...

Several activities such as aquaculture, human and feedstock therapies can directly release antibiotics into water. Due to high stability, low hydrolysis and non-biodegradation, they can accumulate in the aqueous environment and transport to aquatic species. Here, we synthesized amine-functionalized porous carbons (ANC) by a direct-pyrolysis process of NH2 -MIL-53(Al) as a sacrificial template at between 600 and 900 °C and utilized them to eliminate chloramphenicol antibiotic from water. The NH2 -MIL-53(Al)-derived porous carbons obtained high surface areas (304...

The highly conjugated and hydrophobic characteristics of microporous organic networks (MONs) have largely impeded their broad applications in sample pretreatment especially for the polar or ionic analytes. In this work, a novel uniform hollow shaped sulfonate group functionalized MON (H-MON-SO3 H-2) was synthesized via the sacrificial template method for the efficient solid phase extraction (SPE) of sulfonamides (SAs) from environmental water, milk, and honey samples prior to HPLC analysis. H-MON-SO3 H-2 exhibited large specific surface area, penetrable space, good stability, and numerous hydrogen bonding, electrostatic, hydrophobic and π-π interaction sites, allowing sensitive SPE of SAs with wide linear range (0...

This review synthesized implementation literature on group-based exercise programs in physiotherapy. MEDLINE and EMBASE databases were searched for English and French articles published between 2000 and 2022. Through a two-step process (titles/abstracts and full text), two independent reviewers selected studies. The independent reviewers then extracted data and assessed study quality using the Mixed Methods Appraisal Tool (MMAT). A total of 31 studies involving 4,555 participants were included. Data on the group-based programs were extracted using the Consensus on Exercise Reporting Template (CERT) and reported narratively...

Due to their uncontrollable assembly and crystallization process, the synthesis of mesoporous metal oxide single crystals remains a formidable challenge. Herein, we report the synthesis of single-crystal-like mesoporous Li2 TiSiO5 by using soft micelles as templates. The key lies in the atomic-scale self-assembly and step-crystallization processes, which ensure the formation of single-crystal-like mesoporous Li2 TiSiO5 microparticles via an oriented attachment growth mechanism under the confinement of an in-situ formed carbon matrix...

With its substantial theoretical capacity, silicon (Si) is a prospective anode material for high-energy-density lithium-ion batteries (LIBs). However, the challenges of a substantial volume expansion and inferior conductivity in Si-based anodes restrict the electrochemical stability. To address this, a yolk-shell-structured Si-carbon composite, featuring adjustable void sizes, was synthesized using tin (Sn) as a template. A uniform coating of tin oxide (SnO2 ) on the surface of nano-Si particles was achieved through a simple annealing process...

A study has been conducted to investigate the formation of intermediate phases during the crystallization of SAPO-11 molecular sieves from reaction mixtures with a varying template (di-n-propylamine) DPA/Al2 O3 ratio. It was found that changing the DPA/Al2 O3 ratio from 1.0 to 1.8 in the initial reaction gels leads to the formation of different intermediate phases during crystallization into a SAPO-11 molecular sieve. It is shown that at the ratio template/Al2 O3 = 1.0, an intermediate amorphous silicoaluminophosphate is formed; at 1...

Salmonella typhimurium, as a major foodborne pathogen, poses a serious threat to public health safety worldwide. Here, we present a colorimetric biosensor based on aptamer recognition-induced multi-DNA release and peroxidase-mimicking three-way junction DNA-silver/platinum bimetallic nanoclusters (3WJ/DNA-Ag/PtNCs) for the detection of S. typhimurium. In this method, S. typhimurium specifically binds to the aptamer and releases multiple cDNAs to form the three-way junction DNA structure and synthesize silver/platinum bimetallic nanoclusters, which induces signaling changes...

Znln2 S4 has great prospects for photocatalytic water splitting to hydrogen by visible light. Herein, a novel Znln2 S4 -In-MOF (ZnInM S4 ) photocatalyst is elaborately synthesized by in situ method with In-MOF as the template and In3+ as the source. ZnInM S4 overcomes the fast interface charge recombination and a sluggish charge lifetime via the formed heterojunctions. Photoelectrochemical measurements reveal that the charge-transfer kinetics is enhanced since In-MOF is introduced to act as a reliable charge-transport channel...
