However, commonly used disinfection methods, such as chlorination, ultraviolet irradiation, and membrane filtration, experience several challenges such as continuous chemical dosing, the spread of antibiotic resistance genes (ARGs), and intensive energy consumption.
Methods: Here, we perform a simultaneous elimination of pathogens and ARGs in drinking water using local electric fields and in-situ generated trace copper ions (LEF-Cu) without external chemical dosing.

Anterior cruciate ligament (ACL) injuries are prevalent among athletes, necessitating surgical intervention followed by comprehensive rehabilitation. Recently, the integration of nutraceuticals - bioactive compounds from food sources - into rehabilitation protocols has shown promise in enhancing recovery outcomes. This review explores the potential benefits of various nutraceuticals, including omega-3 fatty acids, collagen supplements, vitamin D, glucosamine and chondroitin, curcumin, and branched-chain amino acids (BCAAs), in ACL rehabilitation.

However, it remains a critical challenge to constrain their covalent expansions in the one-dimensional (1D) direction. Here, we developed a general approach to fabricate 15 different highly crystalline COFs with zigzag-packed 1D porous organic chains through the condensation of V-shaped ditopic linkers and X-shaped tetratopic knots.

The selective semihydrogenation of C H to C H in crude C H (with ~1 vol % C H contamination) is a crucial process in the manufacture of polyethylene. Comparing to conventional thermalcatalytic route with Pd as catalyst under high temperature with H as hydrogen source, photocatalytic C H reduction reaction with H O as hydrogen source can achieve high selectivity under milder conditions, but has rarely been reported. Here, we present a kind of ultrathin metal-organic framework nanosheets (Cu-Co-MNSs) that demonstrate excellent catalytic activities in the semihydrogenation of C H .

However, artificial CODH-like catalysts are generally limited to the inner sphere effect and only applicable in organic solvents or for electrocatalysis. Herein, an aqueous CODH mimic with both inner and outer spheres for photocatalysis is reported.

However, the underlying correlation between the enhanced photostability and supramolecular structure at the molecular level has not yet been fully understood. Herein, we develop a biomimetic vesicular membrane-based polyporphyrin photocatalyst exhibiting excellent photocatalytic stability with at least activity time of 240 h in hydrogen generation.

However, despite the great success therein, the report on photo-controlled living cationic polymerization has been greatly limited. We demonstrate here a novel decolorable, metal-free and visible light-controlled living cationic polymerization system by using tris(2,4-dimethoxyphenyl)methylium tetrafluoroborate as the photocatalyst and phosphate as the chain transfer agent (CTA) for polymerization of 4-methoxystyrene.

Herein, three small molecules based on perylene diimides are readily prepared for n-type OECTs. The final molecules show preferred energy levels, tunable backbone conformation, and high film crystallinity, rendering them good n-type dopability, favorable volumetric capacities, and substantial electron mobilities.

We implemented full physical corrections (FPC) to Co-SPECT (quantitative Co-SPECT) to improve the image resolution and contrast along with the capability for image quantitation. FPC included attenuation, scatter, resolution recovery, and noise reduction.

This case-control study aimed to evaluate the feasibility of Tc-3PRGD2 imaging for detecting choroidal melanoma (CM) and for monitoring tumor response to plaque brachytherapy (PB). Ten consecutive patients with CM who underwent Tc-3PRGD2 imaging before and 3 months after PB were reviewed.

Tc-3P-RGD2 and SPECT/CT were valuable tools for selecting patient likely benefit from integrin blocking therapy. To evaluate the feasibility of Tc-3P-RGD2 imaging to detect head and neck squamous cell carcinoma, Tc-3P-RGD2 was prepared and the relationship between its accumulation and integrin expression in nude mice bearing HEP-2 or CNE-1 carcinoma xenograft were analyzed. This study demonstrated that Tc-3P-RGD2, with high affinity to integrin , will provide basis for involved individual therapy.

Rhabdomyosarcoma (RMS) is one of the most common primary orbital malignancies. However, orbital RMS is a very rare disease, especially in childhood, and the tumor has a high degree of malignancy and rapid development. The objective of the present study was to investigate the clinical treatment effects of radioactive (125)I seeds interstitial brachytherapy on children with primary orbital RMS, which may provide a new method for treating RMS in clinical applications.
