Gold nanohexagrams via active surface growth under sole CTAB control

“…The morphologies of the nanostructures do not show a clear trend, as the ridges and craters have turned into shattered vertical plates without recognizable pattern. We did not further modulate the reaction parameters because the morphological changes under combined control of CTAB and chiral ligands have been reported by our group and Zhang et al 8,9 A repeated set of experiments showed that the morphology of shattered vertical plates, the blue shift of the CD peaks, and the trend of decreasing intensity were reproducible. Hence, it appears that the chiral inducer needs to get involved early in the growth, otherwise its impact cannot be realized despite the obvious additional growth.…”

“…The most successful current system of chiral induction involves thiol-containing cysteine or its derivatives, which bind strongly on Au nanostructures. [6][7][8][9][10][11] Importantly, these previous studies have all used hexadecyltrimethylammonium bromide (CTAB) as the surfactant during synthesis, but its role is rarely discussed and only a few works recorded the effects of CTAB in the absence of chiral ligands. 8,9,12 CTAB is a highly abnormal ligand/surfactant: it contains a tertiary amine and there is therefore no lone pair available for the formation of coordination bonds to metal atoms.…”

The surfaces of noble metal nanoparticles are generally neutral, with perhaps a few positive charges.…”

A 3D-printed freestanding graphene aerogel composite photocathode for high-capacity and long-life photo-assisted Li–O2 batteries

“…However, current research has mainly focused on optimizing semiconductor materials, ignoring the optimization of photocathode pore structure. [8][9][10][11][12][13][14] Therefore, it is hoped that a suitable photocathode with greater photocatalytic reactivity and a larger specific surface area can be designed by changing the pore structure to store as much Li 2 O 2 in the photocathode as possible.…”

3D printable, excellent temperature adaptable and wearable supercapacitors from TPU/PPy/MnCO3 matrix gel

“…With a better performance than conventional lithium ion batteries, supercapacitors (SCs) are a prominent energy storage technology. [1][2][3][4][5] In addition, micro supercapacitor fabrication and electrolyte selection that might be connected to the body utilizing flexible and flexible materials are receiving a lot of attention. The R. Kumar research group demonstrated micro SCs from a direct laser writing technique and discussed the electrochemical properties of different electrodes and electrolytes.…”
