Capacitive deionization (CDI) is perceived as a promising technology for freshwater production owing to its environmentally friendly nature and low energy consumption. To date, the development of high-performance electrode materials represents the foremost challenge for CDI technology. In this work, the porous bismuthene/MXene (P-Bi-ene/MXene) heterostructure was synthesized using a simple interfacial self-assembly method with two-dimensional (2D) bismuthene and Ti 3 C 2 T x MXene . Within the P-Bi-ene/MXene heterostructure, the porous structure can increase the active site and facilitate ion transport. Simultaneously, MXene effectively enhances the conductivity of the heterostructure, resulting in accelerating electron transport. Due to these attributes, the P-Bi-ene/MXene heterostructure demonstrates high desalination capacity (90.0 mg/g), fast desalination rate, and good cycling performance. The simple self-assembly strategy between 2D/2D materials described herein may offer inspirations for the synthesis of innovative electrode materials with high performance.

By stepwise adding of reducer N 2 H 4 ·H 2 O, cuprous oxide (Cu 2 O) nanoparticles (NPs) with adjustable structures were synthesized. The features of Cu 2 O NPs were characterized by XRD, TEM and UV-Vis absorption spectra. When the reducer was added into the reactant system at one time, the sizes of the Cu 2 O NPs are in the range of 120–140 nm. Most Cu 2 O NPs are solid spheres. As the reducer was divided into two equal parts and stepwisely added, almost all the NPs are hollow spheres with good size (150–170 nm) distribution and dispersity. But when the reducer was divided into three or four equal parts and stepwisely added, the NPs are hollow spheres, core-shell structures or solid spheres, and the sizes distribution of the products is deteriorated. The effect of sodium hydrate (NaOH) was also probed. Addition of NaOH speeded up the nucleation and growth processes of Cu 2 O NPs. With the alkalinity increase, the shells of the hollow spheres become compact and the thicknesses of the shells increase, but the size distribution of the NPs is deteriorated. The absorption spectra of the Cu 2 O NPs are tunable. With the shell thicknesses increase, the absorption peaks have red shifts. An inside-outside growth model of Cu 2 O NPs was proposed to explain the results. The Cu 2 O single crystalline grains grow not only in the reactant solution, but also inside of the hollow nanospheres. The new Cu 2 O nanocrystallines can not only aggregate onto the shells of the nano hollow spheres, but also inside and outside of the hollow spheres, which leads to increasing the shell thicknesses of the hollow spheres, forming core-shell structures or small solid spheres of Cu 2 O NPs, respectively.

The strength and toughness of a material are generally two mutually exclusive properties. Optimization of these properties can be realized by regulating microstructures based on a bio-inspired idea. Herein, we used gelatin as a pore-regulating agent to investigate the effect of microstructural transition from “nacre-like” lamellae to “honeycomb-like” reticulae on the mechanical properties of metal–ceramic composites. By introducing different quantities of gelatin into SiC slurries during freeze casting and infiltrating the sintered SiC scaffolds with pure molten Al, we prepared the Al/SiC (88/12 in volume) composites with variable yet controllable microstructures and further demonstrated that the desired properties could be achieved by tailoring their microstructures. Specifically, the Al/SiC composites with a fully laminated structure exhibited optimal fracture toughness ( K Jc ) of 51.9 ± 2.9 MPa m 1/2 while those with a three-dimensional reticular structure displayed peak three-point flexural strength of 371 ± 6 MPa. The relationship between the microstructures and mechanical properties of the composites was addressed based on material strengthening and toughening mechanisms.

The solar-driven water splitting for the production of renewable green hydrogen fundamentally relies on the exploration of efficient photocatalysts. Nanostructured TiO2is widely recognized as a promising material for photocatalysis, yet it remains hindered by inadequate light harvesting and fast photogenerated carrier recombination. Herein, calcined C/TiO2xerogels with yolk–shell and core–shell nanostructures (denoted as YS-C/TiO2and CS-C/TiO2) were designed and fabricated via a typical sol–gel–calcination assisted approach. Thanks to the encapsulation of carbon nanospheres into TiO2, it effectively enhances light absorption, improves carrier separation, and lessens carrier recombination, making the well-designed YS-C/TiO2composite display a remarkable hydrogen evolution rate of 975 µmol g−1h−1under simulated solar light irradiation and without the use of any co-catalyst, which is approximately 21.7 times that of the commercial TiO2. The work provides an efficacious design concept in developing nanostructured TiO2-based photocatalysts and in boosting broad photocatalytic applications.

Exploring new structural types of polyoxotitanium clusters (PTCs), especially those containing classical polyoxometalates structures, has always been the focus of research in the field of metal-oxo clusters. In this work, we present the synthesis and characterization of three prismatic PTCs: namely, Ti8(μ2-O)3(μ4-O)2(OnPr)6(HOnPr)2(L1)8 (PTC-237; H2L1 = 3,5-di-tert-butylcatechol), Ti12(μ2-O)6(μ3-O)8(OnPr)6(L2)12(L3)2 (PTC-238; HL2 = 1-adamantanecarboxylic acid, HL3 = 2-picolinic acid), and [Ti18(μ2-O)4(μ3-O)16(μ5-O)2(OiPr)18(L3)8](L3)2 (PTC-239). Single-crystal X-ray diffraction analyses indicate that the construction of these prismatic PTCs is based on a stepwise interlayer assembly of {Ti3} and {Ti4} substructures. The diameters of their core skeletons are in the range between 0.9 and 1.3 nm. In particular, lacunary Linqvist-like {Ti4} and {Ti5} building units are found to exist in the structures of PTC-237 and PTC-239. According to the solid-state UV–vis diffuse reflectance measurements, the absorption band of 3,5-di-tert-butylcatecholate-functionalized PTC-237 shifts toward the visible-light region, giving a smaller optical band gap of 1.56 eV in comparison to PTC-238 (3.36 eV) and PTC-239 (3.25 eV).

In this study, the cooking and textural properties of the noodles prepared with whole egg, egg white, and yolk were evaluated firstly. The results showed that the addition of egg white improved the cooking quality of the noodles more significantly compared to that of whole egg and yolk. And the microstructure analysis showed that noodles made with 3.12 % egg white powder (EWP) had smoother surface and denser network structure. Moreover, the EWP strengthened network structure not only limited the leaching out of the amylose but trapped large starch particles. Besides, the rheological and starch structure analysis confirmed the EWP-enhanced network limited the pasting of starch to reduce its viscosity and decreased the crystallinity of starch. This study analyses the mechanism of protein addition on the improvement of cooking properties of noodles based on starch structural changes, which will provide new perspectives on the preparation of noodles with designed properties.

Conventional fog collection efficiency is subject to the inherent inefficiencies of its three constituent steps: fog capture, coalescence, and transportation. This study presents a liquid bridge synergistic fog collection system (LSFCS) by synergistically utilizing a liquid bridge and interconnected porous superhydrophilic structures (IPHS). The results indicate that the introduction of liquid bridge not only greatly accelerates water droplet transportation, but also facilitates the IPHS in maintaining rough structures that realize stable and efficient fog capture. During fog collection, the lower section of the IPHS is covered by a water layer, however due to the effect of the liquid bridge, the upper section protrudes out, while covered by a connective thin water film that does not obscure the microstructures of the upper section. Under these conditions, a one-step fog collection mode is realized. Once captured by the IPHS, fog droplets immediately coalesce with the water film, and are simultaneously transported into a container under the effect of the liquid bridge. The LSFCS achieves a collection efficiency of 6.5 kg m −2 h −1 , 2.3 times that of a system without a liquid bridge. This study offers insight on improving fog collection efficiency, and holds promise for condensation water collection or droplet manipulation.

Hierarchical structure design and heterostructure engineering are effective strategies for enhancing hydrogen evolution reaction (HER) performance, yet their synergistic integration remains underexplored. In this work, a novel hierarchical P-NiMoO 4 @Net-like Ni 2 P heterostructure HER electrocatalyst was prepared via a two-step hydrothermal method followed by low-temperature phosphorization. The three-dimensional net like Ni 2 P was closely integrated with one-dimensional phosphorus-doped NiMoO 4 micro/nanorod arrays, enabling hierarchical structural assembly and the formation of synergistic heterointerfaces. The hierarchical structure significantly increased active site exposure, with a double-layer capacitance of 254.4 mF cm −2 , more than five times that of single-component Ni 2 P (48.4 mF cm −2 ). Density functional theory calculations revealed that the heterostructure lowered the d-band center of active Ni 3 sites and optimized the hydrogen adsorption energy, thereby enhancing HER activity. The P-NiMoO 4 @Net-like Ni 2 P catalyst exhibited an alkaline HER overpotential of 49 mV at a current density of 10 mA cm −2 . It also maintained stable operation for 100 h at 10mA cm −2 and 120 h at 100mA cm −2 . This study demonstrates the potential of integrating hierarchical and heterostructural strategies, providing a reference for advanced nanostructured catalyst development.

Graphical A novel transition metal tellurite phosphate Cd 3 (PO 4 )(TePO 6 ) features a new type of {[TePO 6 ] 3− } ∞ chain was obtained by solid-state reactions, and its electronic structure and optical properties are studied systematically. New inorganic crystals containing multiple anions have received extensive attensions recently in view of their abilities to be potential multifunctional materials. Among them, tellurite-phosphates with simple chemical components are relatively rarely studied. Here, one novel tellurite phosphate Cd 3 (PO 4 )(TePO 6 ) was obtained through conventional soild-state reaction, and it is the first tellurite-phosphate only possessing d 10 transition metal. It crystallizes in the monoclinic space group P 2 1 / c , and its structure features an interesting {[TePO 6 ] 3− } ∞ chain constructed by corner-sharing connected PO 4 and TeO 4 tetrahedra. Meanwhile, we obtained a new phase of Cd 3 (PO 4 ) 2 and Cd 1.725 Mg 1.275 (PO 4 ) 2 in the exploration of tellurite-phosphates, and they also crystalize in the centric space group P 2 1 / c . Crystal structures, theoretical calculations on their electronic structure and birefringence have been studied, together with the IR and UV-vis-NIR diffuse reflectance spectra.

We present a citrus-peel-like micro-cavity structure for the design of durable Slippery Liquid-Infused Porous Surfaces (SLIPSs). Owing to the re-entrant and enclosed nature of micro-cavity, lubricant oils can be stabilized by mitigating mass loss resulting from liquid displacement and shear drainage, respectively. Citrus-peel-like micro-cavity SLIPS displays two orders of magnitude enhancement in durability in the droplet-sliding test when compared with micro-pillar SLIPS and smooth lubricant surface. We demonstrated precise droplet manipulation without liquid loss and cross-contamination by harnessing the Marangoni effect with photo-thermal control. Cavity-smooth SLIPS with large adhesion contrast was patterned to initiate multiple droplet coalescences for on-demand neutralization reaction. The citrus-peel-like micro-cavity SLIPS would be beneficial to various applications, such as multi-step chemical reactions and bio-detections that require loss-free, contamination-free, and programmable droplet manipulation.

Synthesis of anisotropic carbonaceous nano- and micro-materials with well-ordered mesoporous structures has attracted increasing attention for a broad scope of applications. Although hard-templating method has been widely employed, overcoming the viscous forces to prepare anisotropic mesoporous materials is particularly challenging via the universal soft-templating method, especially from sustainable biomass as a carbon resource. Herein, the synthesis of biomass-derived nanowire-arrays based mesoporous nanorods and teeth-like superstructures is reported, through a simple and straightforward polyelectrolyte assisted soft-templating hydrothermal carbonization (HTC) approach. A surface energy induced interfacial assembly mechanism with the synergetic interactions between micelles, nanowire, nanorods, and polyelectrolyte is proposed. The polyelectrolyte acts not only as a stabilizer to decrease the surface energy of cylindrical micelles, nanowires and nanorods, but also as a structure-directing agent to regulate the oriented attachment and anisotropic assembly of micelles, nanowires, and nanorods. After a calcination treatment, the carbon nanorod and teeth-like superstructure are successfully coupled with Ru to directly produce supported catalysts for the hydrogen evolution reaction, exhibiting much better performance than the isotropic nanospheres based catalyst. This HTC approach will open up new avenues for the synthesis of anisotropic materials with various morphologies and dimensions, expanding the palette of materials selection for many applications.
