Rising prices and reports of empty shelves in major economies have drawn attention to the functioning of supply chains that normally operate smoothly in the background. Among the issues, the long delays that port congestion may have caused in delivering goods to consumers and firms have been...

The addition of granular activated carbon (GAC) enhanced the performance of up-flow anaerobic sludge blanket (UASB) reactor treating blackwater at 35 °C. DNA were extracted from the sludge and biofilms attached to GAC and submitted for shotgun sequencing. In addition, the acyl-homoserine...

We study the effect of COVID-19 containment measures on expected stock price volatility in some advanced economies, using event studies with hand-collected minute-level data and panel regressions with daily data. We find that six-month-ahead volatility indices dropped following announcements of...

Heat conduction, being one of the most common types of energy, occurs everywhere at any time in nature. On the long journey to explore the optimal structural design for the ubiquitous heat conduction problem, many insights have been reported, yet still identifying the best structural...

Antimony (Sb), a toxic metalloid, has serious negative effects on human health and its pollution has become a global environmental problem. Bio-reduction of Sb(V) is an effective Sb-removal approach. This work, for the first time, demonstrates the feasibility of autotrophic Sb(V) bio-reduction...

Herein, amorphous catalysts were employed to investigate the catalytic ozonation system, revealing the degradation mechanism and influencing factors (Cu/Mn ratio, O3 concentration, temperature, and humidity) for toluene catalytic ozonation. Cu0.2MnOx exhibited the highest toluene oxidized (~92%...

Naphthalimide-based molecules, namely NEN and NTA, were designed and utilized as versatile cathode interlayers in organic solar cells (OSCs). Compared with one-armed NA previously reported and two-armed NEN, the NTA with a three-armed molecular structure exhibits more clearly the...

In quantum-dot light-emitting diodes (QLEDs), poly[(9,9-dioctylfluorenyl-2,7-diyl)-alt(4,4’-(N-(4-butylphenyl))] (TFB) has been one of the most widely used hole-transport layer (HTL) materials. However, for solution-processed especially ink-jet printed QLEDs, TFB normally suffers from low...

The inherent limitations of semiconductors include low carrier concentrations and the non-directional utilization of internal carriers, which exhibit sluggish photocatalyst-mediated redox activities. Here, a novel high-performance Na-bridged photocatalyst with nitrogen vacancies (WNCN) was...

Adjustment of electronic structure in carbon skeleton has a major impact on the performance of carbon material for oxygen reduction reaction (ORR). Decreasing work function of carbon skeleton is one of the significant research branches for the development of carbonaceous catalysts. Herein,...
