Shape‐Selective Molecular Separations Enabled by Rigid and Interconnected Confinements Engineered in Conjugated Microporous Polymer Membranes

open access: yesAdvanced Science, EarlyView.
Conjugated microporous polymer membranes with narrowly distributed network pores are prepared by diffusion‐modulated electropolymerization. This approach precisely controls the monomer diffusion and coupling processes, regulating the crosslinking degree to prevent broad aggregate pores and microporous defects.

Implanted Microneedles Loaded with Sparfloxacin and Zinc‐Manganese Sulfide Nanoparticles Activates Immunity for Postoperative Triple‐Negative Breast Cancer to Prevent Recurrence and Metastasis

open access: yesAdvanced Science, EarlyView.
Hyaluronic acid Microneedles (MNs) are loaded with Sparfloxacin (SP) and zinc‐manganese sulfide (ZMS) for the postoperative in situ treatment of triple‐negative breast cancer (TNBC) to prevent cancer recurrence and combat wound infection. These microneedles enhance antitumor immunity by activating the cGAS‐STING pathway, suppress tumor growth, reduce ...

Tunable Transfer‐Hydrodeoxygenated Upgrading of Lignin‐Derived Propylphenols to Versatile Value‐Added Alkane‐Based Chemicals

open access: yesAdvanced Science, EarlyView.
A gaseous hydrogen‐free catalytic system employing Raney Ni and HZSM‐5 with isopropanol upgrades lignin‐derived phenols into value‐added alkanes. By tuning catalyst ratios and temperature, selective pathways yield versatile products including propylbenzene (62%), 4‐propylcyclohexanol (92.2%), propylcyclohexene (93.3%), and propylcyclohexane (93.2 ...

Experimentally demonstration of the repulsive Casimir force in the gold-cyclohexane-PTFE system [PDF]

open access: yesarXiv, 2019
The experimentally demonstration of Casimir force transition from attraction to repulsion is still challenging. Herein, the Casimir forces for a sphere above a plate immersed in different liquids were precisely measured using Atomic force microscope, and the long-range repulsive Casimir force in the gold-cyclohexane-PTFE system is observed for the ...
