Abstract Chemical activation with assisted microwave irradiation was used to produced activated carbon from orange peel waste. The activating agent potassium hydroxide (KOH) concentrations of 2 M, 3 and 4 M. done for 15 minutes a 630 Watt output power. KOH concentration affected the physical properties OP-ACxM. With increasing concentration, interlayer spacing ( d 002 100 ) grew, stack height L...

Reconfigurable intelligent surface (RIS)-assisted orthogonal frequency division multiplexing (OFDM) systems have aroused extensive research interests due to the controllable communication environment and performance of combating multi-path interference. However, as premise RIS-assisted OFDM systems, accuracy channel estimation is severely degraded by increased possibility insufficient cyclic pr...

In this study, a nickel ferrite (NiFe2O4) system was constructed to purify phenol solution in water. During the process, influences of several critical operating parameters including NiFe2O4 amount, PS dosage, MW power, initial pH value, and different natural water anions were systematically studied. The results indicated that performed excellently regarding removal efficiency (97.74%) within 3...

Despite their prevalence in organic synthesis, the application of boronic acids (BAs) as alkyl radical precursors visible-light-assisted photocatalyzed reactions has been limited by high oxidation potential. This study demonstrates prominent ability amide solvents, namely, N,N-dimethylacetamide, to participate hydrogen-bonding interactions with BAs, thus enabling modulation potential toward gen...

Collaborative control architectures assist human users in performing tasks, without undermining their capabilities or curtailing the natural development of their skills. In this study, we evaluate our collaborative control architecture by investigating the visual attention patterns of robotic wheelchair users. Our initial hypothesis stated that the user would require less visual attention for d...
