In this review investigate the apple orchard waste (AOW) is potential organic resources to produce multi-product and there sustainable interventions with biorefineries approaches to assesses the apple farm industrial bioeconomy. The thermochemical and biological processes like anaerobic digestion, composting and , etc., that generate distinctive products like bio-chemicals, biofuels, biofertilizers, animal feed and biomaterial, etc can be employed for AOW valorization. Integrating these processes can enhanced the yield and resource recovery sustainably. Thus, employing biorefinery approaches with allied different methods can link to the progression of circular bioeconomy. This review article mainly focused on the different biological processes and thermochemical that can be occupied for the production of waste to-energy and multi-bio-product in a series of reaction based on sustainability. Therefore, the biorefinery for AOW move towards identification of the serious of the reaction with each individual thermochemical and biological processes for the conversion of one-dimensional providences to circular bioeconomy.

This paper reports the efficiency of polymer membranes without and with small amount of commercial plant extract involved in removal of nickel ions from synthetically wastewater using a mini-electrodialysis cell. The membranes were obtained by phase inversion technique at room temperature. The structure of the resulting membranes was investigated through Fourier Transform Infrared (FTIR-ATR) spectroscopy and environmental Scanning Electron (ESEM) microscopy. FTIR spectra show that the peak at 2325 cm−1 shifted to a higher wavenumber when commercial plant extract is added in the polymer matrix. This is probably due to the N-H and O-H stretching vibration and indicated that the plant extract was successfully incorporated into the bulk membrane. ESEM images of the prepared membrane samples showed that the introduction of plant extract into the mesoporous channels reduces the pore size of the membrane. The membrane doped with commercial plant extract showed an extraction percentage of 52% after 1 h of electrodialysis experiment. © SGEM2017 All Right Reserved.

We have designed a series of mechanochromic devices inspired by nature with the capabilities of changing transparency and "switching on/off" luminescence in response to mechanical stimuli. The key to accomplish these excellent optical properties is to control strain-induced surface engineering, that is, the longitudinal cracks opening and transverse invaginated folds. All of these devices are comprised of a rigid thin layer atop polydimethylsiloxane (PDMS) based elastomer, which can be facilely and quickly fabricated. For transparency change mechanochromism, the folds and cracks with excellent light trapping and scattering capabilities can endow high opaqueness to the originally highly transparent samples. The evolution of crack opening and fold-ridge mechanisms are captured through finite analysis that incorporates damage and cracks in the rigid thin layer. For luminescent mechanochromism, the strain-tunable cracks on the UV shield layer act as "gates" to mediate the traveling of UV light to "switch on/off" the luminescence of mechanochromism. This device exhibits a remarkably high strain responsive sensitivity, demonstrating an excellent sensing capability for detecting mechanical failure or damage. All the mechanochromisms also show outstanding durability and reversibility.

The concept of resilience can be realized in natural and engineering systems, representing the ability of system to adapt and recover from various disturbances. Although resilience is a critical property needed for understanding and managing the risks and collapses of transportation system, an accepted and useful definition of resilience for urban traffic as well as its statistical property under perturbations is still missing. Here we define city traffic resilience based on the spatio-temporal clusters of congestion in real traffic, and find that the resilience follows a scale free distribution in two-dimensional city road networks and one-dimensional highways, with different exponents, but similar exponents in different days and different cities. The traffic resilience is also revealed to have a novel scaling relation between the cluster size of the spatio-temporal jam and its recovery duration, independent of microscopic details. Our findings of universal traffic resilience can provide indication towards better understanding and designing these complex engineering systems under internal and external disturbances.

Harvesting the Vibration Energy of BiFeO3Nanosheets for Hydrogen Evolution

In this study, mechanical vibration is used for hydrogen generation and decomposition of dye molecules, with the help of BiFeO 3 (BFO) square nanosheets. A high hydrogen production rate of ≈124.1 μmol g −1 is achieved under mechanical vibration (100 W) for 1 h at the resonant frequency of the BFO nanosheets. The decomposition ratio of Rhodamine B dye reaches up to ≈94.1 % after mechanical vibration of the BFO catalyst for 50 min. The vibration‐induced catalysis of the BFO square nanosheets may be attributed to the piezocatalytic properties of BFO and the high specific surface area of the nanosheets. The uncompensated piezoelectric charges on the surfaces of BFO nanosheets induced by mechanical vibration result in a built‐in electric field across the nanosheets. Unlike a photocatalyst for water splitting, which requires a proper band edge position for hydrogen evolution, such a requirement is not needed in piezocatalytic water splitting, where the band tilting under the induced piezoelectric field will make the conduction band of BFO more negative than the H 2 /H 2 O redox potential (0 V) for hydrogen generation.
