Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Biomimetic 3D‐Printed Adaptive Hydrogel Bioadhesives Featuring Superior Infection Resistance for Challenging Tissue Adhesion, Hemostasis, and Healthcare

open access: yesAdvanced Materials, EarlyView.
Biomimetic 3D‐printed hydrogel bioadhesives (PTLAs) are designed to address the limitations of existing bioadhesives, offering solutions for challenging tissue adhesion and enhanced healthcare. These PTLAs feature robust wet/underwater tissue adhesion/sealing, superior freeze/pressure and infection resistance, and adaptive self‐healing/gelling capacity,

An MS-CASPT2 Study of the Photodecomposition of 4- Methoxyphenyl Azide. Role of Internal Conversion and Intersystem Crossing [PDF]

open access: yes, 2019
Aryl azides photochemistry is strongly dependent on the substituent relative position, as has been studied by time resolved resonant Raman (TR3) spectroscopy for 4-methoxyphenyl azide and its isomer 3-methoxyphenyl azide.

Polymorphism and thermodynamic ground state of Silver fulminate studied from van der Waals density functional calculations

open access: yes, 2014
Silver fulminate (AgCNO) is a primary explosive, which exists in two polymorphic phases namely orthorhombic (\emph{Cmcm}) and trigonal (\emph{R$\bar{3}$}) forms at ambient conditions.

Photothermally Powered 3D Microgels Mechanically Regulate Mesenchymal Stem Cells Under Anisotropic Force

open access: yesAdvanced Materials, EarlyView.
The photothermally powered microgel is designed to mechanically train mesenchymal stem cells using spatially patterned exogenous forces in three‐dimensional (3D) workspaces. When microgels are activated selectively via photothermal actuation, locally confined tens of nN forces are exerted on cells, triggering osteogenic differentiation in encapsulated ...

Sacrificial Biofabrication for Vascularization: Concept, Materials, Technologies, and Applications

open access: yesAdvanced Materials, EarlyView.
Vasculature is indispensable for tissue viability in regenerative medicine. The sacrificial biofabrication enables precise fabrication of vascular channels by using temporary templates that are subsequently removed. This review defines the concept and delves into sacrificial materials, surrounding materials, fabrication technologies, and biomedical ...

Dual‐Strategy Direct Photocatalytic Patterning for Efficient Perovskite Nanocrystal LED Displays

open access: yesAdvanced Materials, EarlyView.
A dual‐strategy is presented direct photocatalytic patterning that enables high‐resolution, nondestructive patterning and fabrication of efficient crosslinked perovskite nanocrystal‐light‐emitting diodes (PeNC‐LEDs). The first strategy systematically identifies thiol crosslinkers for advanced direct photocatalytic patterning.

A Sustainable Synthetic Approach to Tacrine and Cholinesterase Inhibitors in Deep Eutectic Solvents under Aerobic Conditions

open access: yesMolecules
An enhanced, sustainable, and efficient method for synthesizing tacrine, achieving a 98% yield, has been developed by replacing volatile organic compounds with more eco-friendly solvents such as deep eutectic solvent (DESs). The optimized protocol scales

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

open access: yesAdvanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.
