Chemoselective Formation of Unsymmetrically Substituted Ethers from Catalytic Reductive Coupling of Aldehydes and Ketones with Alcohols in Aqueous Solution [PDF]

open access: yes, 2015
A well-defined cationic Ru–H complex catalyzes reductive etherification of aldehydes and ketones with alcohols. The catalytic method employs environmentally benign water as the solvent and cheaply available molecular hydrogen as the reducing agent to ...

Modular Synthesis of 2,3,4,6‐Tetrasubstituted Thieno[2,3‐c]furans Based on Formal [3+2] Cycloaddition Utilizing [1,2]‐Phospha‐Brook Rearrangement / Brønsted Base‐Mediated Cyclization Strategy

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract A modular synthesis of 2,3,4,6‐tetrasubstituted thieno[2,3‐c]furans, which employs a formal [3+2] cycloaddition utilizing the [1,2]‐phospha‐Brook rearrangement and a subsequent Brønsted base‐mediated cyclization, has been established, providing an efficient access to a wide range of densely functionalized thieno[2,3‐c]furans that are otherwise

Nanocrystalline Cellulose from the Solitary Tunicate Phallusia Mammillata, a Valuable Nanocellulose Precursor

open access: yesAdvanced Sustainable Systems, EarlyView.
This study explores the potential of locally harvested Phallusia mammillata, a tunicate usually discarded as waste from mussles farming as a viable source for producing various high‐grade cellulose derivatives in the form of nanofibrils (NFC) and nanocrystals (CNC). Abstract Ascidians are ubiquitous filter‐feeding marine invertebrates, the only animals

Opportunities in Therapeutic mRNA Stabilization: Sequence, Structure, Adjuvants and Vectors

open access: yesAdvanced Therapeutics, EarlyView.
Current mRNA lipid nanoparticles rely on cold storage, which increases the cost and reduces access to the vaccines. As mRNA expands to other clinical opportunities, better methods to stabilize the medicines during shipping, storage, and delivery are needed.

Epithelial Cell Mechanoresponse to Matrix Viscoelasticity and Confinement Within Micropatterned Viscoelastic Hydrogels

open access: yesAdvanced Science, EarlyView.
Extracellular matrix (ECM) viscoelasticity and spatial confinement regulate cellular processes such as cancer progression, yet their interplay remains poorly understood. By developing fibronectin (FN)‐micropatterned viscoelastic hydrogels mimicking breast cancer mechanics, this study explores breast epithelial cell mechanoresponse to ECM ...
