Since the outer surface interaction of Q[n]s (OSIQ, including self-, anion- and aromatic-induced OSIQs) was proposed in 2014, it has become the most important research area in our group to construct various Q[n]-based supramolecular frameworks via the OSIQ strategy. Herein, we report a novel supramolecular framework constructed using cucurbit[8]uril (Q[8]) and 4-sulfocalix[6]arene (SC[6]A). This Q[8]/SC[6]A-based supramolecular framework is a product via the perfect combination of self-, anion- and aromatic-induced OSIQs. This framework has the characteristics of easy preparation and high stability with the most important feature being the sequence selective capture of specific metal cations, such as common alkali- and alkaline earth metal ions, and renewability. Thus, this framework may be used in seawater desalination, potassium ion enrichment, radioactive cesium ion pollution source treatment, Gruinard's treatment or water softening and other applications.

Due to the asymmetry of the double-side structure of press-pack insulated-gate bipolar transistors (PP IGBTs), the physical significance and calculation method of parameters in the thermal resistance network model are not clear, which brings some challenges to the junction temperature (Tj) estimation method using this model. In this paper, two kinds of double-side thermal resistance network physical models are proposed by calculating the heat flow ratio on both sides and taking the temperature of the top and bottom case as the reference isothermal point. In the single chip packaging and double-side water cooling conditions, the simulation results show that the maximum relative error of the junction temperature estimation of two kinds of models established and the traditional model is -0.13%, 1.21% and -1.42%, respectively. The experiment also verifies that the proposed model has the highest accuracy and a certain range of application for the junction temperature estimation of PP IGBTs. © 2024 IEEE.

A chiral fluorescence sensor based on metal–organic frameworks for enantioselective recognition

Materials Letters 2025年 396卷

Here, we developed a chiral cyclodextrin-based MOF (CDMOF) functionalized with diacetylbenzaldehyde hydrazone (Zone), termed as Zone@CDMOF, for the enantioselective recognition of chiral amines. Zone molecule encapsulated in CDMOF converts to deacetylated form (Zone-OH) by selectively reacting with chiral amine enantiomers via acetyl-O bond cleavage, accompanied by increased fluorescence. Zone@CDMOF exhibits enantioselectivity toward r-phenethylamine (r-PEA) enantiomer over s-PEA, which was confirmed by infrared spectroscopy (IR) and 1H NMR analysis. This work provides a rational design of chiral porous materials for the recognition of chiral species. © 2025 Elsevier B.V.

Zirconia-doped hydroxyapatite (HAP) ceramics were fabricated using VAT photopolymerization (VPP). Ceramic samples with various zirconia doping levels were produced using microwave sintering. The effects of different sintering temperatures and zirconia doping content on the shrinkage, porosity, microstructure, and mechanical properties of hydroxyapatite ceramics were investigated. The results indicate that zirconia doping increases the porosity and reduces the shrinkage of the ceramic samples. The ceramics display anisotropy that becomes more pronounced as porosity increases. With higher porosity, circular pores tend to cluster into elongated pores, resulting in a more evident anisotropic behavior in the materials. Doping with ZrO2 effectively mitigates this anisotropy, achieving optimal results at a doping level of 4 wt%. The optimal sintering temperature for HAP ceramics is 1200 °C. At a doping level of 6 wt%, the material demonstrates outstanding mechanical properties along with high porosity, specifically a flexural strength of 51.01 ± 5.61 MPa, an elastic modulus of 18.51 ± 1.07 GPa, and a compressive strength of 116.15 ± 7.73 MPa, with a porosity of 31.40 %. Overall, these results suggest that a zirconia doping level of 6 wt% enables the attainment of high porosity in hydroxyapatite ceramics while preserving excellent mechanical performance. © 2025 Elsevier Ltd and Techna Group S.r.l.

In this paper, a simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) is employed to assist uplink dual-user multiple-input multiple-output (MIMO) communications, which can create virtual links from users in both transmission and reflection region to the base station throughout the entire space, thereby enhancing coverage and reducing energy consumption. We aim to jointly design the transmit covariance matrix for the two users and the phase shift matrices for the STAR-RIS, based solely on statistical channel state information. The implemented alternating optimization algorithm for joint design is achieved by utilizing the derived closed-form expression of the ergodic sum rate. Specifically, the optimal transmit covariance matrices for the two users are determined using a water-filling algorithm, meanwhile the suboptimal solutions for the phase shift matrices of the STAR-RIS are obtained via the projection gradient ascent method. Simulation results demonstrate that the proposed algorithm achieves superior system performance. © 2024 IEEE.
