“…Nevertheless, there are differences in the degree of biodegradation among the biocomposites. All these results are in accordance with the previous studies reported by many researchers in case of flax, kenaf and sisal fibre based PLA biocomposites exposed to soil burial weathering [14,[19][20][21]. The burial process reduced the strength properties of the biocomposites which is attributed to polymer degradation and loss of adhesion/debonding between fibre and matrix.…”

Natural fibre and biopolymer based biocomposites are getting rising consideration owing to their renewability and biodegradation properties. In order to observe the behavior of these biocomposites in outdoor applications, its environmental reaction properties such as soil biodegradation need to be analyzed. In this study coir fibres (CF) and pineapple leaf fibres (PALF) reinforced polylactic acid (PLA) hybrid biocomposites (CF/PALF/PLA), pure PLA, pure CF (C30) and PALF (P30) biocomposites were fabricated through heat compounding and hot pressing methods. Effect of soil biodegradation on the tensile properties of PLA, CF and PALF biocomposites, and hybrid biocomposites were assessed and evaluated by Soil Burial tests. Tensile samples of all biocomposites undergoes soil burial test for 60 and 90 days at natural condition. After the subjected period, the results indicated that there is reduction in weight, tensile strength and modulus values of biocomposites owing to lignin degradation and fibre-matrix bonds.

“…The usual way multi-rotor drones maneuver is by using a tilt heuristic by running the rotors at different speeds [14, 15, 27]. This approach has unnecessary constraints, resulting in limited accuracy because there is less control over the movement of the drone.…”

This work presents a new formulation to holistically control four cooperative multi-rotor drones controlled in two pairs. This approach uses a modular relative Jacobian with components consisting of the Jacobians of each individual drone. This type of controller relies mainly on the relative motion between the drones, consequently releasing unnecessary constraints inherent to the control of drones in absolute motion. We present the derivations of all the necessary equations of the modular relative Jacobian to control the four multi-rotor drones. We also present the derivations of the Jacobian for each drone. We implement our proposed method in the Gazebo RotorS simulation using four hexa-rotor drones modeled from Ascending Technologies called firefly drones. We present the simulation results and analyze them to show the effectiveness of our proposed approach.

“…9 Recently, Koley and coworkers reported pyrimidyl or pyridyl groupdirected copper-catalyzed ortho C−H diarylamination of indoles, indolines, anilines, and N-aryl-7-azaindoles with diaryl amines. 10 Moreover, copper, nickel, or cobalt-catalyzed (electrochemical) versions of aromatic C−H amination with nucleophilic amines have been developed. 11 In contrast to directed nucleophilic amination versions, copper-catalyzed electrophilic amination of C(sp 2 )−H bonds is still underexplored.…”

A copper-catalyzed intermolecular electrophilic amination of benzamides with O-benzoyl hydroxylamines was achieved with the assistance of an 8-aminoquinolyl group. With this protocol, good compatibility was observed for a variety of aryl amides and heteroaryl amides, and excellent tolerance with various functional groups was achieved. Significantly, the monoaminated product was overwhelmingly delivered under the simple reaction conditions. Preliminary mechanistic investigations suggested that a radical pathway should be excluded and C–H activation be potentially the rate-determining step.
