Summary: This study investigated the anthocyanin profiles and crossbreeding potential of two different varieties of Camellia sinensis, 'Ziyan' and 'Zijuan'. The hybrid ZZ showed strong heterosis in foliage anthocyanin accumulation, exceeding the content of its parental cultivars. Delphinidin-3-O-galactoside was the most dominant anthocyanin in ZZ. The up-regulation of CsANSs and CsGSTs may play critical roles in the anthocyanin heterosis of ZZ.

Summary: If dark matter interacts too strongly with nuclei, it may become undetectable due to slowing down in Earth's crust or atmosphere. For sub-GeV dark matter, existing approximations are insufficient and computationally expensive simulations are needed. The authors propose a new analytic approximation method for studying the attenuation of light dark matter in Earth, which agrees well with Monte Carlo results and is more efficient for higher cross-sections. They use this method to reanalyze constraints on subdominant dark matter.

Summary: This paper reports the unprecedented use of hematite as a black pigment material in rock art and analyzes the physicochemical characteristics of red, purple, and black pigment materials from Jufri Cave, East Kalimantan, using various techniques. The results reveal that hematite is the main component of all pigment materials, but the properties of hematite crystals differ among different pigments, possibly due to high-temperature heating or natural geological and anthropological factors. The variation in crystallinity and octahedral symmetry distortion of hematite structures may account for the color diversity observed in the pigment materials.

Summary: Red or purple coloration of abaxial leaf surfaces is a widespread phenomenon that has evolved independently in multiple plant lineages. This coloration is not only associated with shaded forest understory habitats, but also occurs in many taxa adapted to high light. The most well-supported explanation for this phenomenon is that the red pigments function to protect the leaves from excess light, particularly in light-limited environments.

Summary: The functionalized zinc oxide nanotube coated with MXene layer was successfully prepared using a simple dipping method. The existence of the prepared material was confirmed through various characterization techniques. The modification of ZnO NT with MXene resulted in a decrease in bandgap value and an increase in photoelectrochemical performance. The current density of ZnO NT/MXene was about 0.2 mA/cm2 (1.4 V vs Ag/AgCl), which is twice as high as that of ZnO NT. Additionally, the oxygen evolution of the modified ZnO NT was 1.5 times higher than the pristine one, indicating effective hole junction/charge transfer in ZnO NT/MXene.

Summary: Recently, there has been significant progress in the development of zeolites with two-dimensional structures, also known as nanosheet zeolites, due to their superior catalytic performance compared to conventional zeolite. The thin nanosheet structure of zeolite provides more accessible active sites, allowing for efficient catalytic reactions. Various nanosheet zeolites, including MFI, FAU, MOR, MWW, and TS-1, have been successfully synthesized using direct synthesis methods involving surfactants and/or seeds. Interestingly, the characteristics of these nanosheet zeolites can be easily modified by adjusting the synthesis parameters. Nanosheet zeolites have been extensively studied as catalysts in a wide range of reactions, such as methanol conversion, catalytic cracking, isomerization, alkylation, oxidation/reduction, and lignocellulose conversion. The modification of nanosheet zeolites, such as pillaring, has been shown to enhance their catalytic performance. This review provides a comprehensive overview of the recent progress in nanosheet zeolites, including the challenges and future outlook of nanosheet catalyst technologies.

Summary: This study investigates the impact of ligament gap in NiO mesoporous with different templates on the activity of rGO/NiO in alkaline hydrogen evolution reaction. It is found that the activity of the electrocatalyst is primarily determined by the size of ligament gap rather than the surface area. The results demonstrate that rGO/NiO prepared with KCC-1 template exhibits superior activity due to its larger ligament gap, despite having the smallest surface area. It is suggested that the accumulated hydrogen gas within the NiO mesoporous structure could elevate the internal electrode resistance and reduce overall catalytic activity.

Summary: Mesopores were successfully generated through desilication method and the amount of mesopore was controlled by adjusting OSDA contents in the zeolite framework via partial detemplation. The relative crystallinity remained the same for all the desilicated samples compared to their parents. Furthermore, the occluded OSDA within ZSM-48 may have another role in desilication process, affecting the density and distribution of the acid site. The improved catalytic performance of mesoporous samples, as shown by the lower observed activation energy (Eobs) in LDPE pyrolysis test, further confirmed the benefits of mesopores in enhancing molecule diffusion.

Summary: We synthesized a mesoporous NiFe2O4/MXene nanocomposite for the alkaline HER, which showed significantly improved electrocatalytic activity compared to individual NiFe2O4 and MXene components. The mesoporous structure provided a large surface area and enhanced mass transport, while the incorporation of MXene improved charge transfer kinetics. DFT calculations revealed more favorable H atom adsorption and activation on the NiFe2O4 surface. This study highlights the potential of templated mesoporous nanocomposites for efficient electrocatalysts in alkaline HER and contributes to renewable energy technologies.

Summary: For the first time, a dispersive micro-solid phase extraction (D-mu SPE) based on graphene oxide was used for the ultrasensitive determination of Cd. With this method, Cd can be efficiently extracted from a mixture of alkali and alkaline earth metals without the need for an elution step. The combination of D-mu SPE and SAGD OES significantly reduces matrix effects and improves the tolerance of Cd to alkali metals. The method shows simplicity in the measurement system and the commercially available nanosorbent used.
