All-day passive radiative cooling is a promising cooling technique achieves cooling without any energy input, thereby attracting tremendous attention. Most of the studies focus on building applications, but there remains a lack of information on other potential applications of radiative cooling systems. Herein, we report an application of a polymeric passive radiative cooling coating (PRCC) on the exterior surface of chemical storage tanks, which is often overlooked but exhibits great potential to efficiently control the evaporative loss of the chemicals. The PRCC exhibits strong solar reflectivity (96.2%) and emissivity (95%) in the mid-infrared wavelength range. According to the results of an outdoor test on a small-scale chemical storage container, the PRCC achieves 81.4%, 54.1%, and 19.8% of chemicals saved compared with a raw container, container painted with commercial white paint (CWP), and the shaded raw container, respectively. A numerical simulation is also conducted to estimate the chemical standing loss from an industrial large-scale chemical storage tank. It is found that the PRCC can achieve a saving of over 50% of the chemical compared with commercial white paint for a chemical storage tank, showing a promising potential to be applied on chemical storage systems. • Excellent optical properties of spectral selectivity for radiative cooling. • Achieved all-day sub-ambient cooling on both clear and cloudy days. • Evaporation loss is investigated experimentally and numerically. • Over 50% of chemicals can be saved via the radiative cooling technology.

[Display omitted] • 2′-FL alleviated obesity in HFD mice. • 2′-FL increased energy expenditure and adaptive thermogenesis in HFD mice. • 2′-FL induced the browning of iWAT and increased the activity of BAT. • 2′-FL improved the diversity, structure and composition of gut microbiota. 2′-fucosyllactose (2′-FL) is one of the most prevalent milk oligosaccharides. In this study, the anti-obesity effect of 2′-FL was explored in high-fat diet (HFD)-fed mice. Results showed that 2′-FL alleviated body weight gain, improved serum lipid profiles and increased energy expenditure. Under cold exposure, 2′-FL group showed higher body and rectal temperature, improving adaptive thermogenesis. 2′-FL alleviated lipid accumulation, increased mitochondrial DNA content, as well as upregulated the protein expression of thermogenic markers including UCP1, PRDM16, PGC-1α and the phosphorylation of AMPK in both white and brown adipose tissue. 2′-FL also increased the diversity of gut microbiota in HFD mice. The Bacteroides / Firmicutes ratio, and the Bifidobacterium abundance were increased, while Lachnospiraceae abundance was decreased after 2′-FL treatment. Moreover, 2′-FL to HFD mice altered the bile acid profiles at levels comparable to normal diet group. These results indicates that 2′-FL promotes thermogenesis and modulates gut microbiota to alleviate obesity. [ABSTRACT FROM AUTHOR]

In this work, a novel composite adsorbent coated superhydrophilic-nanostructured heterogeneous surface is proposed to enhance condensation heat transfer. Experiments are conducted under the atmospheric pressure condition with the ambient temperature of 23 ± 2 °C to investigate the water vapor condensation rate of the heterogeneous surfaces coated with different patterns of the composite adsorbent. The condensation rates and the latent heat transfer coefficients of the heterogeneous surfaces are investigated under the quiescent environment. The results show that the heterogeneous surfaces with vertical middle-stripe patterns of the composite adsorbent have better condensation heat transfer performance than the other patterns, showing 45.5%–80.0% improvement compared to the copper surface. It is found that during water condensation on the heterogeneous surfaces, the water film on the superhydrophilic region can be adsorbed by the adjacent composite adsorbent. Consequently, a water-free region is observed on the proposed heterogeneous surfaces, which provides extra fresh nucleation sites for water condensation, leading to an enhancement in the heat transfer performance. Based on this observation, a water film adsorption mechanism is introduced to explain the condensation heat transfer enhancement on the proposed heterogeneous surface, providing a practical and scalable surface treatment method to improve the condensation heat transfer. [Display omitted] • Heterogeneous surfaces formed by adsorbents and superhydrophilic coatings. • Condensation heat transfer evaluation of various heterogeneous surfaces. • Critical improvement in latent heat transfer achieved by heterogeneous surfaces. • Water film adsorption mechanism is introduced to explain enhanced condensation.

Designing porous materials with various nanoscales and dimensionalities is very significant for surface/interfacial interaction and mass transport, and are expected to improve the performance of materials. Herein, we first report the preparation of porous NiCo layered double hydroxide (NiCo LDH) nanotube by utilizing a metal organic framework (MOF) and MoO 3 composite as a precursor. The NiCo LDH nanotube is composed of two-dimension (2D) nanosheet and a high specific surface area of 107 m2 g−1 is achieved. The unique structure of nanotube and high specific surface area can greatly improve the electrical conductivity and electroactive surface area of the material and also shorten the ion transport path, resulting in enhancement of electrochemical performance. When used as electrode material for supercapacitors, the NiCo LDH nanotube shows a high specific capacitance of 1386 F g−1 at a current density of 1 A g−1. Moreover, the asymmetric supercapacitor assembled by active carbon and the NiCo LDH nanotube shows a high capacitance of 94.3 F g−1 at 0.5 A g−1, an energy density of 118 Wh kg−1 at a power density of 108 W kg−1 and excellent stability without any loss in capacitance even after 10000 charge-discharge cycles, indicating that the NiCo LDH nanotube is a very promising supercapacitor electrode material.

In this work, an electric field-enhanced heterogeneous catalytic ozonation (EHCO) was systematically investigated using a prepared FeOx/PAC catalyst. The EHCO process exhibited high sulfadiazine (SDZ) and TOC removal efficiency compared with electrocatalysis (EC) and heterogeneous catalytic ozonation (HCO) process. Almost 100% of SDZ was removed within 2 min, and the TOC removal reached approximately 85% within 60 min. Quenching experiments and EPR analysis suggested that the prominent SDZ and TOC removal performance is supported by the enhanced ·OH generation ability. Further study proved that H 2 O 2 formed by O 2 electrochemical reduction, peroxone reaction and electrochemical reduction of ozone contributed to improving ·OH generation. Furthermore, the EHCO system showed satisfactory stability and recyclability compared to conventional HCO systems, and the SDZ and TOC removal rates were maintained at ≥95% and ≥70% in 16 consecutive recycles, respectively. Meanwhile, XPS analysis and Boehm's titration for the FeOx/PAC catalyst used in HCO and EHCO process confirmed that the external electron supply could restrain the oxidation of surface functional groups of PAC and maintain a balance of the Fe(II)/Fe(III) ratio, which proved the critical role of cathode reduction in catalyst in situ regeneration during long consecutive recycles. In addition, the EHCO system could achieve more than 80% SDZ removal within 2 min in different water matrices. These results confirmed that the EHCO process has a wide application perspective for refractory organics removal in actual wastewater.

In this study, we purified a partially acetylated heteropolysaccharide (Ts1-1A) from the fruit bodies of Trametes sanguinea Lloyd through cold water extraction and serial chromatographic separation. The purified polysaccharide Ts1-1A (12.8 kDa) was characterized as a branched mannogalactofucan with a backbone of alternately connected 1,3-linked α-Fuc p and 1,6-linked α-Gal p , which was partially substituted by non-reducing end units of β-Man p at O -2 and O -3 positions of 1,6-linked α-Gal p. Ts1-1A showed pronounced anti-human cytomegalovirus activity at the concentration of 200 and 500 μg/mL in systematical assessments including morphological changes, western blotting, qPCR, indirect immunofluorescence and tissue culture infective dose assays. Moreover, Ts1-1A exerted its antiviral activity at two distinct stages of viral proliferation manifesting as significantly inhibiting viral protein (IE1/2 and p52) expression and reducing viral gene (UL123 , UL44 and UL32) replication in the HCMV-infected WI-38 cells. At viral attachment stage, Ts1-1A interacted with HCMV and prevented HCMV from attaching to its host cells. While at early phase of viral replication stage, Ts1-1A suppressed HCMV replication by downregulating NQO1 and HO-1 proteins related to oxidative stress as an antioxidant. To sum up, Ts1-1A is a promising anti-HCMV agent which could be developed for HCMV infection prevention and therapy. [ABSTRACT FROM AUTHOR]

[Display omitted] • Cu 2 O@Cu 9 S 5 yolk-shell nanospheres were prepared by a facial wet chemical method. • This catalyst display enhanced electrocatalytic properties for H 2 O 2 reduction. • This catalyst based sensor exhibits excellent H 2 O 2 sensing performance. • Performance include low detection limit, outstanding sensitivity and selectivity. It is urgent to develop highly active catalysts toward hydrogen peroxide (H 2 O 2) sensor in many industrial and biological processes, which usually is limited by high cost of instrumentation requirements and low-accuracy detection at low level. Herein, Cu 2 O@Cu 9 S 5 yolk-shell nanospheres has been synthesized via a facial wet chemical method and applied as electrocatalyst for non-enzymatic H 2 O 2 sensor. These Cu 2 O@Cu 9 S 5 yolk-shell nanospheres with mean sizes of 230 nm consisting of Cu 2 O conductive core and Cu 9 S 5 shell show numerous advantageous characteristics of well-sustained structural integrity, the homogeneous particle size distribution and visible mesoporosity morphology. The significantly improved electrocatalytic activity by catalyzing H 2 O 2 of the Cu 2 O@Cu 9 S 5 yolk-shell nanospheres as a sensor has been obtained by comparing with those neat Cu 2 O nanospheres and Cu 9 S 5 hollow nanospheres. This noticeable property is largely due to the synergistic catalysis effect of the contribution of the Cu 2 O and Cu 9 S 5. Cu 2 O@Cu 9 S 5 yolk-shell nanospheres based non-enzymatic H 2 O 2 sensor displays the relatively wide linear range from 0.1 μM to 3.5 mM with a high sensitivity of 299.74 μA mM−1 cm−2 but low detection limit of 28.83 nM (S/N ≥ 3) for electrochemical detection of H 2 O 2 , which is potentially superior to other similar Cu 2 O-based sensors that has been reported in the literatures. Additionally, this sensor also demonstrates excellent selectivity of H 2 O 2 in the presence of various coactive interferences. This novel Cu 2 O@Cu 9 S 5 yolk-shell nanospheres electrocatalyst provides a broad application prospect for H 2 O 2 sensing. [ABSTRACT FROM AUTHOR]
