Summary: The crystallization kinetics of template-free ultra-small FAU-type zeolite in highly alkaline viscous precursor suspensions has been studied, focusing on a four-step process of preparation, aging, evaporation, and hydrothermal treatment. The properties of the amorphous particles depend on the mixing procedure and alkalinity, with high alkalinity leading to the formation of ultra-small discrete nanoparticles. Formation of the very first micropores in the nanosized particles was confirmed through spectroscopic measurements.

Summary: This study introduces novel lubricant infused hierarchical porous surfaces with self-replenishing and self-reporting capacities inspired by the rapid replenishment of Nepenthes nectaries. These hierarchical inverse opal films exhibit liquid-repelling feature on liquids with different surface tensions and have favorable self-replenishment capacity for stable droplet manipulation. The structural colors from the periodic nanostructure could serve as an optical indicator to monitor the wettability of the surfaces.

Summary: This study used a novel aqueous dispersion of colloidal silica, whose particles' surfaces were modified with an epoxysilane-based coupling agent, to combine with fine MgO powder, generating self-flowing MgO-colloidal silica suspensions of excellent workability. After curing, a dense magnesium silicate hydroxide hydrate protective coating formed over MgO particles, hindering their hydroxylation and volumetric expansion. During thermal treatment, softened silica particles promoted densification. The microstructure after sintering comprised dense MgO grains surrounded by thin layers of forsterite.

Summary: In this study, a carbon nanotube-supported defective polymerized cobalt phthalocyanine composite was prepared and successfully applied as a cathode in photo-assisted lithium-oxygen batteries (LOBs). The introduction of irregular structural defects not only facilitates the diffusion of O2 and Li+ ions, but also accelerates the separation of photoelectrons and holes. The composite showed excellent performance, including high energy efficiency and low polarization, under light irradiation.

Summary: A minimally invasive strategy based on in situ self-assembly of photovoltaic microdevices (PVMs) is presented for manufacturing biomimetic retinas with a wide field of view and high resolution. The PVMs transduce photoelectricity upon visible light illumination to effectively activate the retinal ganglion cell layers. The spatial distribution and packing density of the PVMs within the assembled device are modulated through concentration, liquid discharge speed, and coordinated self-assembly steps. The methodology introduces three unique features: minimally invasive implantation, personalized visual field and acuity, and a device geometry adaptable to retina topography.

Summary: This research presents a new approach to enhance the efficiency and durability of photocatalytic CO2 conversion by designing imine-linked covalent organic frameworks as an electron bridge between the photocatalyst and robust metal active sites. The composite, integrated with defective g-C3N4, achieved a high CO production rate of 37.3 μmol/h with 98.8% selectivity over H2 evolution under visible light irradiation, surpassing other non-noble metal species as cocatalysts. Experimental and theoretical analysis revealed that stabilized Co ions with a six-membered chelating structure effectively improved electron collection and catalyst stability. The study demonstrates the potential of coupling defect-modulated photocatalysts with bridging cocatalysts to enhance CO2 photoreduction performance.

Summary: Porous MgO nanosheets with abundant defects are reported as potential photocatalysts for CO2 reduction. The derived defective MgCO3·3H(2)O shows stable CO2 conversion and increased selectivity towards CH4 under UV-light irradiation. The presence of oxygen vacancies (V(o)s) promotes charge carrier separation and the Mg-V-o sites play a crucial role in CO2 adsorption and photoreduction reactions. These findings may lead to novel discoveries in the field of CO2 conversion.

Summary: Colloidal quantum wells (CQWs) are a promising gain material for optical feedback due to their unique excitonic features from 1D confinement, but current integration methods result in low laser quality. To address this, a liquid-interface kinetically driven self-assembly method is proposed to coat ultrathin CQWs onto silica microsphere cavities, achieving high-quality microlasers with a Q-factor of 13,000 at room temperature. Stable single-mode lasing output is demonstrated through evanescent field coupling in a 2D-3D microcavity configuration, highlighting the potential for future miniaturized colloidal optoelectronic and photonic applications.

Summary: This study introduces a simple and novel method, hydrogen evolution coupled electrodeposition (HECED), for the direct synthesis of defective materials. The D-NiMn LDH catalyst prepared through this method exhibits excellent performance and stability for the oxygen evolution reaction (OER) in alkaline media. Loading FeS nanoparticles onto the D-NiMn LDH creates a heterostructure with ultralow overpotential and fast reaction kinetics. This research provides new insights into designing stable and reusable defective materials.

Summary: Mixed Ni/Co and Ni/Fe metal phosphides with different metal ratios were synthesized through phosphidization of high-surface-area hydroxides grown hydrothermally on carbon cloth. The materials were characterized by X-ray photoemission spectroscopy, X-ray diffraction, energy dispersive X-ray analysis, and electron microscopies. Electrochemical water splitting experiments showed that the best performance in the hydrogen evolution reaction was achieved by materials containing a high amount of ternary compounds, such as NiCoP and NiFeP, with outstanding performance at only 50 mV to achieve 10 mA/cm(2). The best performance in the oxygen evolution reaction was achieved by Ni-Fe materials, which resulted in strong surface oxidation and dissolution of the phosphide/phosphate component, leading to the formation of corresponding metal oxides and hydroxides.

Summary: Recently, the utilization of nanoscale photothermal effects in nanocomposite membranes made of polydimethylsiloxane (PDMS) loaded with NiSe or CoSe nanoparticles has been explored to achieve the crystallization of dissolved salts in brines. Through sunlight irradiation, the plasmonic NiSe and CoSe nanoparticles in the membranes can increase the vaporization of water from brine, leading to supersaturation conditions and subsequent heterogeneous nucleation and crystallization of dissolved salts.
