“…By converting light to energy, the gel could reversibly undergo on-demand hydrolysis and softening, releasing a loaded drug (DOX) from the matrix at a specific site, with gel melting being highly dependent on the power of the laser (between 1-3 W•cm -2 ). Wu et al developed a NIR responsive gel based on a short thermoresponsive peptide (NapGFFYD) with embedded PEGylated 2D niobium diselenide (NbSe2) as the NIR photothermal agent, in a move towards increased biocompatibility (23).…”

Organic electrode materials have attracted significant attention for rechargeable lithium organic batteries owing to the anticipated electrochemical property and environmentally friendly features. Benzoquinone and naphthoquinone as the simplest quinone substances have been considered as promising cathode materials because of their high theoretical specific capacities and discharge voltages. However, they are soluble in most organic liquid electrolytes, which results in poor electrochemical performance. Herein, a novel molecular cathode material based on naphthoquinone, i.e., 2,2'-(1,4-phenylenedithio) bis(1,4-naphthoquinone) (1,4-PNQ), is designed and synthesized. It shows greatly decreased solubility as a result of strong intermolecular interactions. In a lithium half cell, it exhibits high carbonyl utilization of close to 100% with a high initial capacity of 231 mAh g -1 . Meanwhile, 1,4-PNQ presents improved cyclability, retaining a high capacity of 185 mAh g -1 after 120 cycles. Remarkably, it retains 93.5% of the initial capacity after 500 cycles at 5 C rate. This work provides a novel molecular design strategy to develop naphthoquinone-derived cathode materials for high performance lithium organic batteries.

“…Among others, light-driven controlled systems stand out with a wide variety of applications ranging from in vivo drug delivery to control of agrochemicals in the field, where the release of molecules is controlled by light via photochemical, photoisomerization, or photothermal effects . More recently, photothermal materials with light-to-heat conversion properties have also been demonstrated to be effective in light-driven controlled release, where the release of the entrapped molecules can be controlled by light-activated temperature elevations. − Systems composed of nanocarriers with thermal-responsive components and near-infrared (NIR)-absorbing photothermal agents have been demonstrated to be remotely triggered to release active substances.…”

A sunlight-triggered controlled release system comprising environmentally friendly components is presented herein. The combination of a photothermal nanocarrier that can be remotely heated by sunlight and a heat-activatable stopper that can be removed via sunlight-triggered heating of the nanocarriers resulted in a smart controlled release system. Surfaces of halloysite nanotubes (HNTs) were coated with a polydopamine (PDA) layer to create a photothermal nanocarrier that heats up when irradiated with sunlight. The resulting HNT–PDA nanocarriers were impregnated with carvacrol, a volatile essential oil as a model active substance, and were further functionalized with lauric acid, as a stopper layer. The presence of lauric acid hindering the carvacrol release from HNT–PDA nanocarriers was confirmed by differential scanning calorimetry and transmission electron microscopy imaging. HNT–PDA nanocarriers were shown to be heated to 45 °C upon sunlight irradiation for 10 min, demonstrating that their sunlight activation can trigger the melting of the lauric acid stopper. In the absence of the light trigger, the lauric acid stopper slowed down and hindered the carvacrol release. Only 40% of impregnated carvacrol was released from the lauric acid-functionalized nanocarriers in 60 days, whereas all carvacrol molecules were released in 30 days when the lauric acid stopper was not present. Release of carvacrol molecules that were entrapped in the HNT–PDA nanocarriers with the lauric acid stopper was shown to be controlled with sunlight. 10–15% of impregnated carvacrol molecules were released upon sunlight irradiation for 6 h, and carvacrol release stopped when the sunlight irradiation was turned off, where 92% of all carvacrol was released over 6 consecutive light-on/light-off cycles. The presented clay nanotube-based controlled release system comprising a photothermal nanocarrier and a heat-activatable stopper demonstrated excellent sunlight-triggered release behavior and therefore can be utilized in various applications requiring remote control of active substance release.
