The discovery of lead-free hybrid double perovskites provides a viable approach in the search for stable and environmentally benign photovoltaic materials as alternatives to lead-containing systems such MAPbX3 (X = Cl, Br, or I). Following our recent reports (MA)2KBiCl6 (MA)2TlBiBr6, we have now synthesized perovskite, (MA)2AgBiBr6, that has low band gap 2.02 eV is relatively nontoxic. Its electronic structure mechanical optical properties are investigated with combination experimental...
Abstract The layer‐by‐layer (LbL) organic photovoltaics (OPVs) are constructed with wide‐bandgap donor PM1 and narrow‐bandgap acceptor L8‐BO. exciton utilization near cathode is still challenging considering restricted diffusion distance of excitons inability for transferring energy from L8‐BO to PM1. Herein, incorporation into layer (DIA) strategy employed improve cathode. efficiency LbL OPVs can be improved 18.02% 18.81% by incorporating 10 wt% layer, which closely associated efficient...
The nonfullerene acceptor L8-BO as solid additive was incorporated into QLA-PSCs based on PM6 and PY-IT. molecular orientation exciton diffusion length in PY-IT layer can be optimized, resulting the PCE enhanced from 16.14% to 17.74%.
Abstract Two kinds of humidity-induced, bendable smart clothing have been designed to reversibly adapt their thermal insulation functionality. The first design mimics the pores in human skin, which pre-cut flaps open produce Nafion sheets when humidity increases, as might occur during sweating thus permitting air flow and reducing both level apparent temperature. Like pores, can close automatically after perspiration keep wearer warm. second involves thickness adjustable clothes by inserting...
Apolipoprotein A1 (Apo-A1) is a well-recognized biomarker in tissues, closely associated with cardiovascular diseases such as atherosclerosis, coronary artery disease, and heart failure. However, existing methods for Apo-A1 determination are limited by costly equipment intricate operational procedures. Given the distinct advantages of electrochemical immunosensors, including affordability high sensitivity, along unique attributes nanobodies (Nbs), enhanced specificity better tissue...
The coalescence of a drop with flat liquid surface pinches off satellite from its top, in the well-known cascade, whereas two equally sized drops does not appear to leave such satellite. Herein we perform experiments identify critical diameter ratio drops, above which is produced during their coalescence. We find that parent as small 1.55, but grows monotonically Ohnesorge number. daughter size typically about 50% mother drop. However, have identified novel pinch-off dynamics close ratio,...
Abstract A new regime of droplet ejection following the slow deposition drops onto a near-complete wetting solid substrate is identified in experiments and direct numerical simulations; coalescence cascade subsequent to pinch-off also observed for first time. Results simulations indicate that propagation capillary waves lead closely related self-similar behaviour inviscid recoil droplets, motions crests troughs along interface do not depend on wettability surface tension (or Ohnesorge...
Shape memory fibrous membranes (SMFMs) are an emerging class of active polymers, which capable switching from a temporary shape to their permanent upon appropriate stimulation. Quintuple-shape based on the thermoplastic polymer Nafion, with stable structure, achieved via electrospinning technology, and possess broad transition temperature. The recovery multiple shapes electrospun can be triggered by heat in single triple-, quadruple-, quintuple-shape cycle, respectively. fiber morphology...
PM6/Y6:PC 71 BM pseudo-bilayer ternary OSCs were prepared. PC enhances light absorption and boosts V OC , improves the contact between donor layer acceptor layer, which photovoltaic performance device stability significantly.
Abstract The unbalanced electron‐hole mobility is the major bottleneck for boosting photovoltaic performance of organic solar cells. In this study, 2D n‐type inorganic semiconductor material tin sulfide (SnS) prepared and introduced into PM6:Y6 bulk heterojunction cells to improve performance. incorporation SnS promotes Y6 crystallization, renders face‐on orientation molecules dominant. improved active layer morphology suppresses carrier recombination strengthens electron transport....
The coalescence of drops is a fundamental process in the coarsening emulsions. However, counter-intuitively, this can produce satellite, approximately half size original drop, which detrimental to overall coarsening. This also occurs during bubbles, while resulting satellite much smaller, 10 %. To understand difference, we have conducted set experiments using xenon bubbles inside pressure chamber, where continuously raise from 1 up 85 atm and thereby vary density ratio between inner outer...
