Interfacing MXene Flakes on a Magnetic Fiber Network as a Stretchable, Flexible, Electromagnetic Shielding Fabric.

A unique self-standing membrane composed of hierarchical thermoplastic polyurethane (TPU)/polyacrylonitrile (PAN) fibers is prepared by the electrospinning technique, followed by a simple dip-coating process. FeO nanoparticles are uniformly anchored on TPU/PAN fibers during the electrospinning process, enabling the membrane to achieve effective electromagnetic interference shielding (EMI SE) performance. Such a hybrid membrane has a high magnetization of 18.

Da-Cheng-Qi Decoction () Combined with Lactobacillus Acidophilus Improves Gastrointestinal Function of Traumatic Brain-Injured Model Mice.

Objective: To investigate the effects of Da-Cheng-Qi Decoction (DCQD, ) combined with Lactobacillus acidophilus (LA) on the recovery of gastrointestinal (GI) function in traumatic brain-injured (TBI) mice.

Methods: A total of 150 male C57BL/6 mice were randomly divided into sham-injury, normal saline (NS), DCQD (0.4 mL/day), LA (⩾1 × 10 cfu/day LA), DCQD+LA (LA administration at the same dosage after 4 h of feeding DCQD), and ½ DCQD+LA groups (LA administration at the same dosage after 4 h of feeding ½ DCQD dose) by a random number table, 5-8 mice in each group.

Carbon nanotubes-CuO/SnO based gas sensor for detecting HS in low concentration.

Porous CuO/SnO nanofibers were prepared by co-dissolution and electrospinning, followed by annealing, and compounded with different amounts of carbon nanotubes (CNTs, 0-5 wt%). The performance of the composite based sensor was tested in different concentrations of HS range from 0.1 to 0.

Lactobacillus acidophilus Exerts Neuroprotective Effects in Mice with Traumatic Brain Injury.

Background: Traumatic brain injury (TBI) causes dysbiosis and intestinal barrier disruption, which further exacerbate brain damage via an inflammatory pathway. Gut microbiota remodeling by Lactobacillus acidophilus (LA) is a potential intervention.

Objective: The aim of this study was to investigate the neuroprotective effects of LA in TBI and elucidated underlying mechanisms.

Tunable phase resonances in a compound metallic grating with perpendicular bumps and cuts.

We propose a compound metallic grating with perpendicular bumps in each slit and investigate its transmission property theoretically. As the bumps are set symmetrically in the slits, the waveguide resonant peaks for the even (odd) modes exhibit a red-shift (blue-shift) compared with the resonant peaks of grating composed of bare slit. As the bumps are set asymmetrically, we show that the dips in transmission spectrum can be tuned by shifting the position and changing the size of bumps in the slit.
