Abstract Hyperuniform disordered solids (HUDS) waveguides, a type of emerging artificial photonic bandgap (PBG) devices, are demonstrated to possess large, complete, and isotropic PBGs, being promising for developing applications in optoelectronics, nonlinear optics, sensing. However, optical losses HUDS waveguides usually limited by giant light scattering from the irregular distribution cells. Herein, waveguide devices with low large PBGs exploring morphology‐engineering...

An interface for CE-ESI-MS that decouples both the electrical and solution flow rate requirements of separation ionization processes is presented. The uses a tapered beveled stainless steel hollow needle surrounding capillary terminus so inside electrode acts as CE outlet vial outside tip electrospray emitter. No pre-treatment required, enabling use capillaries with any type surface modification. A chemical modifier introduced through second connected to via tee junction can be used improve...
To achieve 1000-fold capacity increase in 5G wireless communications, ultradense network (UDN) is believed to be one of the key enabling technologies. Most previous research activities on UDNs were based very much human-to-human communications. However, provide ubiquitous Internet Things services, machine-to-machine (M2M) communications will play a critical role systems. As number machine-oriented connections increases, it expected that supporting M2M an essential requirement all future...
A comprehensive analysis of heavy metal pollution was conducted in the representative limnetic ecosystems eastern China, which are subject to rapid economic development and population growth. The results demonstrated that average contents with standard deviations Cd, Cr, Cu, Ni, Pb Zn surface sediments were 0.925 ± 0.936, 142 46.8, 54.7 29.1, 60.5 21.6, 61.9 36.0 192 120 mg/kg dry wt., respectively higher values mainly observed southern portion study area, especially basins Southeast Coastal...
Abstract Low‐cost activated carbons with high capacitive properties remain desirable for supercapacitor applications. Herein, a three‐dimensional scaffolding framework of porous carbon nanosheets (PCNSs) has been produced from typical biowaste, namely, ground cherry calyces, the specific composition and natural structures which have contributed to PCNSs having very large surface area 1612 m 2 g −1 , hierarchical pore size distribution, turbostratic structure degree graphitization, about 10 %...
Microplastics (MPs) pollution has drawn increasing concern due to its widespread occurrence and potential risks in the environment. The reliable methods instruments for fast analysis of microplastics less than 5 mm are urgently needed. In this study, a new method based on custom-made portable pyrolysis-mass spectrometry (Pyr-MS) is developed, which enables rapid identification mass related quantification MPs. MPs decomposed compact pyrolyzer then directly analyzed MS by chemical fingerprints...
Electrocatalytic nitrate-to-ammonia conversion is a promising and alternative sustainable approach for replenishing the nitrogen cycle pathway under mild conditions. Developing high-performance functional catalysts key to improving electrocatalytic nitrate reduction reaction (NO3RR), which directly affects overall production rate. Various strategies have been proposed accelerate catalyst interfacial electron transfer increase selectivity toward ammonia production. This paper timely reviews...
Because of their innate chemical stability, the ubiquitous perfluoroalkyl and polyfluoroalkyl substances (PFASs) have been dubbed "forever chemicals" attracted considerable attention. However, stability under environmental conditions has not widely verified. Herein, perfluorooctanoic acid (PFOA), a used detected PFAS, was found to be spontaneously degraded in aqueous microdroplets room temperature atmospheric pressure conditions. This unexpected fast degradation occurred via unique...
ABSTRACT Aqueous zinc‐ion batteries (AZIBs) are considered one of the most viable options for large‐scale energy storage applications due to their high theoretical capacity and abundant reserves. However, issues such as dendritic growth water‐induced corrosion reaction zinc anode have hindered commercialization. To address these challenges, in situ generated multifunctional poly(caffeic acid) (PCA) interface with confined Cu sites oxygen‐containing groups was constructed on surface metal via...

Atmospheric mercury speciation and deposition are critical to understanding the fate of in environment. The importance atmospheric was investigated during an intensive field campaign Bay St. François wetlands late summer 2002. Measured gaseous elemental (GEM), reactive (RGM), particulate (PM: 0.1–2.5 μm) concentrations were 0.85–2.16 ng/m 3 (average 1.38 ), 0–22 pg/m 3.63 0.5–18 6.44 respectively. PM RGM represented <1% total mercury. We reported first synchronized automated...
To improve the ecological conditions, Chinese government adopted six large-scale restoration programs including 'Three-North Shelterbelt Project', "Grain for Green Project" and "Beijing-Tianjin Sand Source Control Project". Meanwhile, these ecologically vulnerable areas have experienced frequent droughts. However, little attention has been paid to impact of drought on effectiveness programs. Taking Beijing-Tianjin Region (BTSSR) as study area, we investigated role droughts program trends...
