The increasing requirements for wearable and portable electronics are driving the interests of high performance fiber supercapacitor. Layered double hydroxide (LDH) is broadly used in electrode materials, owing to the adjustability of components and the unique lamellar structure. However, limited active sites and poor electrical conductivity hinder its applications.

Liquid metal (LM) shows the superiority in smart wearable devices due to its biocompatibility and electromagnetic interference (EMI) shielding. However, LM based fibers that can achieve multifunctional integrated applications with biodegradability remain a daunting challenge. Herein, versatile LM based fibers are fabricated first by sonication in alginate solution to obtain LM micro/nano droplets and then wet-spinning into LM/alginate composite fibers.

Here, we describe a ruthenium-catalysed decarboxylative unsymmetric -C-H azaarylation/-C-H alkylation a traceless directing group relay strategy. The installation of a 2-pyridyl functionality carboxyl directed -C-H activation is critical to promote decarboxylation and enable -C-H bond alkylation to streamline the synthesis of 4-azaaryl-benzo-fused five-membered heterocycles. This protocol is characterized by high regio- and chemoselectivity, broad substrate scopes, and good functional group tolerance under redox-neutral conditions.

Background: Numerous genome-wide association studies revealed that SNPs (single nucleotide polymorphisms) at the (phosphatase and actin regulator 1) locus strongly correlate with coronary artery disease. However, the biological function of PHACTR1 remains poorly understood. Here, we identified the proatherosclerotic effect of endothelial PHACTR1, contrary to macrophage PHACTR1.

Nanocomposite conductive fibers are of great significance in applications of wearable devices, smart textiles, and flexible electronics. Integration of conductive nanomaterials into flexible bio-based fibers with multifunctionality remains challenging due to interface failure, poor flexibility, and inflammability. Although having broader applications in textiles, regenerated cellulose fibers (RCFs) cannot meet the requirements of wearable electronics owing to their intrinsic insulation.

The direct hydrodimerization of acrylates and acrylonitrile offers a general streamlined access to industrially important intermediates to nylon 6,6. However, a practical catalytic method for this process has thus far underdeveloped owing to the challenges in regioselectivity and environmental compatibility of applied reagents. Here, we report a cobalt-catalyzed tail-to-tail hydrodimerization of activated alkenes driven by a visible-light photoredox catalysis at ambient temperature, which is applicable to both adipates and adiponitrile synthesis from potentially renewable feedstocks.

Developments in applications such as rocket nozzles, miniature nuclear reactors and solar thermal generation pose high-density heat dissipation challenges. In these applications, a large amount heat must be removed in a limited space under high temperature. In order to handle this kind of cooling problem, this paper proposes liquid metal-based microchannel heat sinks.

Article Synopsis
  • The study focuses on the Dll4-Notch1 signaling pathway, which is critical for blood vessel formation and specificity, noting that blocking this pathway can lead to excessive angiogenesis.
  • Researchers developed a peptide called TAT-ANK that inhibits this signaling by competing with activated Notch1, which was tested in both lab (in vitro) and animal (in vivo) settings to assess its effects on blood vessel formation.
  • The results indicate that TAT-ANK effectively reduces Dll4 expression and Notch1 activation, promoting angiogenesis, making it a potentially valuable tool for future research and treatment of diseases linked to blood vessel growth.

Clinical trials of Dll4 (Delta-like 4) neutralizing antibodies (Dll4nAbs) in cancer patients are ongoing. Surprisingly, pulmonary hypertension (PH) occurs in 14% to 18% of patients treated with Dll4nAbs, but the mechanisms have not been studied. Here, PH progression was measured in mice treated with Dll4nAbs.

Liquid metal nanodroplets not only share similar metallic properties and nanoscale effect with solid metal nanoparticles, but also possess the additional uniqueness in nonvolatile fluidity and ambient sintering ability into continuous conductors. In most cases, liquid metal nanodroplets are encapsulated into ultrathin and fragile shells of oxides and amphiphile monolayers, and may be hindered from incorporating homogeneously into various composites through conventional processing methods. In this study, ring-opening polymerization is found to be initiated by sonicating the liquid metal EGaIn in fluidic lactones.

Protein nanostructures in living organisms have attracted intense interests in biology and material science owing to their intriguing abilities to harness ion transportation for matter/signal transduction and bioelectricity generation. Silk nanofibrils, serving as the fundamental building blocks for silk, not only have the advantages of natural abundance, low cost, biocompatibility, sustainability, and degradability but also play a key role in mechanical toughness and biological functions of silk fibers. Herein, cationic silk nanofibrils (SilkNFs), with an ultrathin thickness of ∼4 nm and a high aspect ratio up to 500, were successfully exfoliated from natural cocoon fibers quaternization followed by mechanical homogenization.

Liquid metal (LM) droplets show the superiority in coalescing into integral liquid conductors applicable in flexible and deformable electronics. However, the large surface tension, oxide shells and poor compatibility with most other materials may prevent spontaneous coalescence of LM droplets and/or hybridisation into composites, unless external interventions (e.g.

Article Synopsis
  • Decreased levels of VEGF-A mRNA are traditionally linked to retinal vessel regression caused by hyperoxia, but recent findings challenge this idea, suggesting other factors may be at play.
  • Inactivation of Dll4-Notch1 signaling has been shown to reduce vessel regression during hyperoxia, raising questions about how sprouting angiogenesis contributes to retinal health.
  • Experiments with young mice indicate that while VEGF-A is suppressed in response to hyperoxia, Dll4 and Notch1 signaling in regressing blood vessels is inhibited, leading to significant vessel regression, contradicting the belief that VEGF-A downregulation is the main cause.

Article Synopsis
  • The study investigates the relationship between circulating dendritic cells (DCs) and monocytes in patients with unstable angina pectoris (UAP) and ST-segment elevation myocardial infarction (STEMI) to better understand their roles in different stages of atherosclerosis.
  • A total of 48 UAP patients and 31 STEMI patients were analyzed alongside control groups, revealing decreased levels of specific DCs (mDC2s) in patients with these conditions, while Mon2 subsets were found to be elevated.
  • The findings suggest that circulating Mon2 could be a potential indicator of atherosclerotic plaque severity, especially in patients with specific plaque characteristics like thin-cap fibroatheroma (TCFA).*
