Small Renal Masses: Incidental Diagnosis, Clinical Symptoms, and Prognostic Factors

open access: yesAdvances in Urology, 2008
Introduction. The small renal masses (SRMs) have increased over the past two decades due to more liberal use of imaging techniques. SRMs have allowed discussions regarding their prognostic, diagnosis, and therapeutic approach.

Exciton Binding Energy Modulation in 2D Perovskites: A Phenomenological Keldysh Framework

open access: yesAdvanced Functional Materials, EarlyView.
The intrinsic screening effects are successfully decoupled from structural distortion by rigorously designing a series of 2D perovskites. This enabled us to demonstrate how the dielectric environment modulates the quasiparticle bandgap and exciton binding energy.

Initial orbit determination of BDS-3 satellites based on new code signals

open access: yesGeodesy and Geodynamics, 2018
For the two newly launched satellites (PRN number 27 and 28) of the future global BeiDou navigation satellite system (BDS-3), there is no available broadcast ephemeris data and other initial orbit information, but the initial orbit is the fundamental of ...

Robust and Reversible Thermofluorescence in Solvent‐Free Thermoplastic Polyurethane Composites

open access: yesAdvanced Functional Materials, EarlyView.
Thermofluorescent polymer composites with high‐contrast optical outputs are prepared by solvent‐free blending of indenoquinacridone dye into a thermoplastic polyurethane matrix. The temperature‐dependent fluorescence originates from aggregation–dissociation of the dye molecules, regulated by competing hydrogen bonds from the polymer matrix.

Polyferrocene‐Based Cubosomes: Conversion to Magnetic Mesoporous Microparticles, Supramolecular Modification, and Oxidation Response

open access: yesAdvanced Functional Materials, EarlyView.
Polyferrocene block copolymers are synthesized and assembled into micron‐sized polymer cubosomes with double diamond lattice and pore diameter of ≈30 nm. The ferrocene functionality is retained within the polymer cubosome wall as demonstrated on supramolecular modification, and oxidative disassembly.

Bio‐Orthogonally Crosslinked Supramolecular Polymer Bottlebrush Hydrogels for Long‐Term 3D Cell Culture

open access: yesAdvanced Functional Materials, EarlyView.
Fibrous benzenetrispeptide (BTP) hydrogels, fabricated via strain‐promoted azide‐alkyne cycloaddition (SPAAC) crosslinking, form robust, bioinert networks. These hydrogels can support 3D cell culture, where cell viability and colony growth depend on the fiber content.
