SLN and NLC are carriers of liposoluble substances with solid lipids or mixed lipids as the structural core and with surfactant-stabilized oil-in-water structure. SLN and NLC are composed with oils, emulsifiers and other components. SLN and NLC can be prepared by high energy preparation processes (high pressure homogenization, microjet and ultrasonic) and low energy preparation processes (variable temperature phase transition, microemulsion, film contact and constant temperature reverse transformation). The quality characteristics were evaluated by particle size, Zeta potential, loading capacity, encapsulation rate and crystallization behavior of lipid matrix. Based on the advantages of low toxicity, low biodegradability, high biocompatibility and large-scale production of SLN and NLC, they have become a research hotspot to protect active substances in food or medicine as delivery carriers.

Biomaterials capable of continuously inactivating pathogens are essential for suppressing transmission of infectious diseases, such as epidemic cerebrospinal meningitis and pulmonary tuberculosis. Here, capillary condensation of air moisture within nano‐confined spaces between superhydrophilic rigid nanorods is shown and target microbiology spontaneously stretch and inactivate aerosolized microorganisms. Specifically, the negative Gaussian curvature‐shaped water condensate causes fluidic straining, comprising surface tension and Laplace pressure, strong enough to deform and eliminate the selected bacteria. Plate counting quantifies the sharply reduced contact‐killing period for superhydrophilic and bare nanorods (6 vs 100 min for E. coli, 20 vs 120 min for S. aureus) under relative humidity of 70%. Theoretical calculations and experimental studies indicate increased mechanical straining and mechano‐bactericidal by improving air moisture content. To further illustrate utility, long‐term antibacterial medical masks are fabricated by integrating such nanorods onto commercial fabrics. Collectively, these findings highlight the immense potential of capillary condensation‐induced fluidic straining as an eco‐friendly, broad‐spectrum, and highly efficient antibacterial strategy.

Southeast Asia plays a crucial role in global food production and trade, yet it grapples with challenges related to food security, regional stability, and security. Cultivated land is the material foundation for ensuring food production. With the development of society and the economy, people's food consumption has undergone significant changes. This paper employs a comprehensive approach to analyze trends in food consumption, the cultivated land footprint, and associated land pressures in Southeast Asia over the period 1961–2019. The main findings are as follows: (1) Between 1961 and 2019, the total food consumption in Southeast Asia surged by 3.1 times. Notably, the proportion of livestock-based foods increased steadily from 6.62% in 1961 to 16.82% in 2019. (2) Due to advancements in agricultural productivity across Southeast Asia, the cultivated land footprint for food consumption only increased by 0.7 times, showcasing a diminishing demand for grain-cultivated land. (3) On the whole, the pressure of food consumption on cultivated land in Southeast Asia is on the decline, albeit with considerable variations among different countries. The Philippines is facing a relative undersupply, whereas Thailand has experienced the lowest cultivated land pressure. (4) Encouraging a shift towards a Mediterranean-style diet, aligned with existing dietary patterns, holds promise for reducing future pressures on cultivated land and promoting better health outcomes for the populace in Southeast Asia.

The test quality of noncontact instruments is an important issue that has aroused social concern at present, which is also widely used in the power quality management of telecommunication systems. The fuzzy logic algorithm can be used in power quality testing to analyze the power quality of electrical equipment. Based on the advantage of the fuzzy logic algorithm, this paper studied the quality control strategy and evaluation algorithm of noncontact instrument testing and drew a conclusion. In terms of the investigation on the safety of power quality measurement, it was concluded that the method of noncontact instrument testing power quality improved the safety of voltage quality, current quality, power supply quality, and power consumption quality. In the investigation of the accuracy of the power quality measurement, it was concluded that the noncontact instrument was used to measure power quality, which greatly improved the accuracy of measurement. In terms of the investigation on the rapidity of the power quality measurement, it was concluded that the use of the noncontact instrument to test power quality could greatly improve the rapidity of current quality measurement and that the rapidity of the power quality measurement could be improved by more than 70%. In the aspect of economic investigation of the power quality measurement, it was concluded that the use of the noncontact instrument to test power quality could greatly improve the economic efficiency of the power quality measurement. In the aspect of fuzzy logic evaluation in power quality management, it was concluded that most of the power quality grades of the selected research objects were excellent. Therefore, the fuzzy logic method was very meaningful for power quality evaluation. [ABSTRACT FROM AUTHOR]

Metal‐organic frameworks (MOFs), bridging metal‐containing second building units by organic ligands, have provided a versatile platform for the design of heterogeneous catalysis. In the last decade, various photo‐responsible MOFs have been designed and prepared, exhibiting outperformed catalytic performance. Among them, MOFs featuring organic photosensitizers for photoinduced organic transformations remain less investigated, due probably to the large steric demands and low symmetry of typical organic dyes. In view of the promising potential of integrating versatile MOFs with organic photosensitizers, this Concept summarizes recent advances in this research area. [ABSTRACT FROM AUTHOR]

Building an interconnected filler network is the most effective way for polymer composites to attain a high thermal conductivity while minimizing the amount of fillers. However, previous approaches for network construction either have to be performed ex situ or rely on magnetic or electrical fields to achieve in situ formation, limiting their practical applications. Here we report a novel strategy to fabricate the filler network in situ without the assistance of any external fields. Thermally expandable microspheres (EMs) are added to the composite and their expansion at elevated temperature forces the conductive fillers to concentrate and align along the boundaries between adjacent microspheres, forming a continuous and densified 3D network. The obtained boron nitride nanosheet (BNNS)/EM/polydimethylsiloxane (PDMS) composite has a low density (0.55 g cm−3), low dielectric constant (<2.3), and excellent flexibility, while still exhibiting a high thermal conductivity of 0.94 W m−1 K−1 (9.82 vol% BNNS), which is 3.1 times that of randomly distributed ones. In addition, it has a low interface thermal resistance (20.93 mm2 K W−1), only 1% of that of the assembled structure. These comprehensive properties make the composite ideal for thermal management of aerospace devices, high frequency electronic devices, and wearable electronics. [ABSTRACT FROM AUTHOR]
