Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots

open access: yesAdvanced Materials, EarlyView.
A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Esterified Cholesterol Conjugates Enable LNP‐Mediated mRNA Delivery to the Blood–Brain Barrier Following Intravenous Administration

open access: yesAdvanced Materials, EarlyView.
A cholesterol‐conjugated lipid library enabled the identification of a ligand‐free LNP platform for efficient mRNA delivery to brain endothelial cells via systemic administration. This platform achieves selective BBB targeting without disrupting barrier integrity, and enables modulation of neuroinflammation and vascular function without requiring trans‐

Self‐Assembling Copolymers Encapsulating Single Endothelial Cells Induce Endogenous ECM Deposition and Vascular Regeneration

open access: yesAdvanced Materials, EarlyView.
This study presents the first demonstration of stable sub‐50‐micron single‐cell GPM vesicles fabricated through the intrinsic self‐assembly of an amphiphilic copolymer. Hierarchical assembly of cell containing GPM vesicles into microspheres enable tunable, sustained cell delivery with immune protection.

Phase‐Engineered MoS2 Quantum Monolayer Catalysts

open access: yesAdvanced Materials, EarlyView.
A new type of catalyst model—phase‐engineered MoS2 quantum‐monolayer catalyst (∼0.8 nm thick, < 6 nm in the lateral size; switchable freely among metallic 1T, semiconducting 2H, and a hybrid phase of metallic‐semiconducting 1T‐2H)—is reported. It can efficiently and stably drive photochemical H2, syngas and ammonia synthesis as a catalyst or co ...

Charge‐Reversed Lipid Nanoparticles Enable Encapsulation of Pt2L4 Nanocages for In vivo Anti‐Cancer Treatment

open access: yesAdvanced Materials, EarlyView.
Charge‐reversed lipid nanoparticles (revLNPs) enable efficient encapsulation and delivery of cationic Pt2L4 nanocages. Encapsulation preserves potent anticancer activity while improving circulation, reducing vascular leakage, and promoting favorable biodistribution in vivo.

Temperature Dependence of the Complexation Mechanism of Celecoxib and Hydroxyl-β-cyclodextrin in Aqueous Solution

open access: yesPharmaceutics, 2014
Hydroxypropyl-β-cyclodextrin (HP-β-CD) is commonly used as a complexation reagent to solubilize compounds with poor aqueous solubility to improve in vivo dosing. However, the degree of solubility enhancement was often limited by the formation of only a 1:

Microbial Solubilization of Coal

open access: yesBiotechnology Progress, 1986
AbstractSeveral different strains of fungi have been shown to solubilize some types of low‐ranked coal, apparently by an extracellular process. Oxidative pretreatment enhances the microbial action, allowing the use of a variety of coal feedstocks. The resulting product, which is primarily a mixture of polar organic compounds with moderate to high ...

Linking Polyelectrolyte Modification and Enzyme‐Catalyzed Phenolic Acid Functionalization of Cellulose Fiber for Functional Foams

open access: yesAdvanced Materials Technologies, EarlyView.
Cellulose fibers functionalized using cationic poly(Dimethyldiallylammonium chloride) (polyDADMAC) and laccase‐mediated ferulic acid system are processed into foams using different surfactants (Anionic, cationic, and non‐ionic). Fiber–surfactant interactions influence foam stabilization and porous structure formation during convective drying, producing
