Water-injected meat leads to microbial growth, which affects the health of consumers. A colorimetric porous polymer microneedle patch was designed and prepared using photopolymerization of an acrylate monomer with porogen to be the substrate, and cobalt (II) chloride as color change indicator and tartrazine as the reference. The color of the microneedle patch changed from green to yellow green and to yellow as the increase of moisture concentration.

Flexible electrochromic devices (FECDs) are widely explored for diverse applications including wearable electronics, camouflage, and smart windows. However, the manufacturing process of patterned FECDs remains complex, costly, and non-customizable. To address this challenge, a strategy is proposed to prepare integrated FECDs via multi-material direct writing 3D printing.

Precise imaging-guided therapy of a pulmonary metastasis tumor is of great significance for tumor management and prognosis. Persistent luminescence nanoparticles (PLNPs) are promising probes due to their excitation-free and low-background imaging characteristics. However, most of the PLNP-based probes cannot intelligently distinguish between normal and tumor tissues or balance the needs of targeted accumulation and rapid metabolism, resulting in false positive signals and potential side effects.

Photocatalysis is considered as an environmentally friendly and sustainable method as it can produce active species to degrade pollutants. However, its applications are hindered by the turbidity of pollutants and the requirements for continuous or repeated in situ irradiation. To avoid the need for continuous in situ irradiation in the photocatalytic process, herein we report the doping of Cu(II) ions into zinc gallate (ZnGaO) as traps to capture photo-generated electrons.

Article Synopsis
  • Photocatalytic carbon dioxide reduction is a method for generating carbon monoxide (CO) to combat bacteria, but existing techniques primarily use visible light, which doesn't penetrate deeply into tissues.
  • A new photothermal CO catalyst (NNBCs) has been developed to generate CO efficiently using a 1064 nm laser, which enhances the breakdown of bicarbonate for CO production.
  • In tests on an osteomyelitis model, NNBCs successfully suppressed bacterial growth and reduced inflammatory reactions simultaneously, marking a significant advancement in antibacterial strategies.

  • - The Mongolian snake gourd, a valuable herbal medicine in China, is facing a serious root rot issue on a 20-ha farm in Zhenjiang City, leading to a 70% disease incidence and a 50% reduction in production as of 2021-2022.
  • - Symptoms of the disease include yellow mottling on new leaves, wilting of upper leaves, and browning at the base of the stem, eventually causing the plants to die.
  • - Researchers isolated a specific fungus from infected plants, leading to the identification of a representative strain for further analysis, revealing distinct conidial features that could help in understanding the disease.

Near-infrared (NIR)-emitting persistent luminescence nanoparticles (PLNPs) are ideal optical imaging contrast reagents characterized by autofluorescence-free optical imaging for their frontier applications in long-term bioimaging. Preparation of uniform small-sized PLNPs with excellent luminescence performance is crucial for biomedical applications, but challenging. Here, we report a facile magnesium doping strategy to achieve size-independent boost of NIR persistent luminescence in typical and most concerned ZnGaO:Cr PLNPs.

Background: Ginkgo biloba extract preparations are commonly used in ophthalmology to improve circulatory disorders and provide neurotrophic support for the treatment of optic neuropathy. However, their use also carries a higher risk of adverse drug reactions (ADRs), some of which can be severe and even life-threatening, such as anaphylactic shock. This case report highlights the importance of recognizing and managing ADRs associated with ginkgo biloba extract in ophthalmology clinical practice.

This paper addresses the orbital rendezvous control for multiple uncertain satellites. Against the background of a pulsar-based positioning approach, a geometric trick is applied to determine the position of satellites. A discontinuous estimation algorithm using neighboring communications is proposed to estimate the target's position and velocity in the Earth's Centered Inertial Frame for achieving distributed rendezvous control.

Smart sensors are expected to be sustainable, stretchable, biocomfortable, and tactile over time, either in terms of mechanical performance, reconfigurability, or energy supply. Here, a biocompatible piezoelectric electronic skin (PENG) is demonstrated on the base of PZT-SEBS (lead zirconate titanate and styrene ethylene butylene styrene) composite elastomer. The highly elastic (with an elasticity of about 950%) PENG can not only harvest mechanical energy from ambient environment, but also show low toxicity and excellent sensing performance toward multiple external stimuli.

Pulsars, especially X-ray pulsars detectable for small-size detectors, are highly accurate natural clocks suggesting potential applications such as interplanetary navigation control. Due to various complex cosmic background noise, the original pulsar signals, namely photon sequences, observed by detectors have low signal-to-noise ratios (SNRs) that obstruct the practical uses. This paper presents the pulsar denoising strategy developed based on the variational mode decomposition (VMD) approach.
