We present a study of narrow filaments toward massive infrared dark cloud, NGC 6334S, using the Atacama Large Millimeter/submillimeter Array (ALMA). Thirteen gas are identified H$^{13}$CO$^{+}$ line, while single continuum filament is revealed by emission. The compact radial distribution with median width $\sim$0.04 pc narrower than previously proposed `quasi-universal' 0.1~pc width. higher spatial resolution observations and higher-density tracer tend to identify even lower mass filaments....

Abstract Biodegradable antimicrobial gauzes are environmentally friendly medical dressings taking essential role in the protection and healing of wounds. Poly (butylene adipate terephthalate) (PBAT) offers a promising platform for exploiting biodegradable attributed to its exceptional biodegradability, biocompatibility, processability, flexibility. To date, most work is focused on utilizing electrostatic spinning fabricate PBAT gauzes. The exhibit unsatisfactory tensile strength breaking...
<p>Wearable microgrids, a wearable system with integrated energy harvesting, storage, and regulation modules, sensors, have potential to support human healthcare. However, microgrids not reached viability due their high costs limited performance, stability, biocompatibility, awaiting significant breakthroughs, especially in material science filed. Single-atom materials (SAMs), one of the most promising forefronts material, can overcome shortcomings mentioned above provide many extra...
Abstract DR21(OH) ridge, the central part of a high-mass star- and cluster-forming hub-filament system, is resolved spatially kinematically into three nearly parallel fibers (f1, f2, f3) with roughly north–south orientation, using observations molecular transitions H 13 CO + (1 − 0), N 2 NH D 1,1 1 0,1 ) Combined Array for Research in Millimeter Astronomy.

This study presents the in situ synthesis of CNT@SrTiO3 nanocomposite films for development high-performance flexible supercapacitors. The process involved use organic–inorganic hybrid polymers containing metal elements as precursors thermal decomposition reaction under a reducing atmosphere. Due to formation chemical bonding between Ti and CNTs, interface STO CNT surface could provide additional active sites ion transport storage. Thereby, incorporation SrTiO3 nanoparticles into CNTs...
Hole transport materials (HTM) play a vital role in the performance of perovskite solar cells (PSCs). Optimizing molecular structure HTMs has been proven to be an important method for improving PSCs’ efficiency and stability. Herein, novel dibenzofuran‐terminated spiro‐type HTM with extending π‐conjugation is designed developed, named spiro‐BNF. The structure–property relationship also studied spiro‐OMeTAD spiro‐DBF as reference. results show that spiro‐BNF improved hole mobility glass...

Abstract Hypoxia and its induced autophagy are involved in the initiation progression of liver fibrosis. Proprotein convertase subtilisin/kexin type 9 (PCSK9) has been recognized as a potential regulator autophagy. Our previously reported study found that PCSK9 expression increased fibrosis anti-PCSK9 treatment alleviated injury. This aimed to investigate mechanism on by inhibiting hypoxia-induced Carbon tetrachloride-induced mouse hepatocyte line AML12, cultured under hypoxic condition,...
Abstract MWC 349A is one of the rare stars known to have hydrogen radio recombination line (RRL) masers. The bright maser emission makes it possible study dynamics system at milliarcsecond (mas) precision.

Abstract Through a simple and effective method for preparing broadband reflective liquid crystal films, the advantages of three‐layer system are expanded based on two‐layer system. The cholesteric crystals form prepolymerized layer after semi‐curing. In design top prepolymerization layer, there is less content chiral compound R5011, which results in formation molecules with larger pitch. Mainly by controlling polymerizable monomers UV‐absorbing dyes (CLCs), polymer network density gradient...
