Invisible near‐infrared thermo‐stimulated luminescence from carbon dots enabled by stepwise energy transfer for concealed information encryption

Responsive Materials, EarlyView.
A fully metal‐free near‐infrared (NIR) thermo‐stimulated luminescent system is developed by embedding carbon dots into a carbon nitride matrix and integrating multistage Förster resonance energy transfer. The system exhibits long‐term charge retention, rewritable optical memory, and highly concealed NIR readout, promising for secure data encryption and

Photo‐responsive carbon dots for pyroptosis‐mediated anti‐tumor application

Responsive Materials, EarlyView.
Photo‐responsive CDs generate ROS to induce tumor cell pyroptosis, thereby stimulating antitumor immunity. Abstract Pyroptosis refers to a kind of lytic programmed cell death, characterized by the release of pro‐inflammatory cytokines during the process. Owing to its immune response stimulation ability, pyroptosis has garnered considerable attention in

Synthesis of Samarium‐incorporated X‐ray‐sensitive nanoparticles and hydrogels: Diverse applications in radiation monitoring and dynamic information display

Smart Molecules, EarlyView.
Sm3+‐doped α‐NaLuF4 and β‐NaLuF4 were synthesized. The X‐ray‐activated persistent luminescence abilities and afterglow properties can be well controlled. Sm3+‐doped β‐NaLuF4 exhibits remarkable afterglow ability. The hexagonal β‐NaLuF4:3%Sm3+‐incorporated hydrogel can be further programmed with other types of hydrogels to enable tunable emission ...

Concurrent tunable structural color, luminescence, and afterglow in single ZnS: X@SiO2 spheres via SiO2‐nanoarmor and calcination decoupling collaborative strategy

Smart Molecules, EarlyView.
For the first time, tunable structural color, luminescence, and afterglow are integrated into single ZnS:X@SiO2 spheres via a SiO2‐nanoarmor and calcination decoupling strategy, achieving 250–410 nm monodisperse wurtzite spheres with 91% phase conversion, 12.8% PLQY, and 12.27 s afterglow. Abstract The integration of structural color, photoluminescence,

Fire Testing and Hazard Assessment for Flame Retardant Polymer Composites

Safety Science and Technology, EarlyView.
Flame retardant polymer composites are now being evaluated with more than pass or fail flammability tests. Heat release, smoke, toxicity, and system‐level behavior are receiving more attention, and multi‐scale methods are being used to describe fire hazard under more realistic conditions.

Creating a Masterpiece. The Road to (and Beyond) Woodward and Hoffmann's 1969 Angewandte Chemie Treatise

The Chemical Record, EarlyView.
This publication describes how R. B. Woodward and Roald Hoffmann crafted their masterpiece publications. Illustrations include Woodward's first draft of the famous “Violations There are none. Nor can violations be expected of so fundamental a principle of maximum bonding.” Original but discarded text shows the stepwise paths toward the W‐H masterpieces.

On 3‐MMC: A Cathinone I Have Come to Know and Love

Anthropology of Consciousness, EarlyView.
ABSTRACT This article attempts to complicate the mythology of a compound in a state of becoming. I will trace lightly its origins as a cultural disruptor and how I am implicated in this imperative. Introducing you to 3‐MMC will require multiple modes of storytelling and taking of liberties, drawing on literature reviews, practice‐based research, prose,
