The realization of novel technological opportunities given by computational and autonomous materials design requires efficient and effective frameworks. For more than two decades, aflow++ (Automatic-Flow Framework for materials Discovery) has provided an interconnected collection of algorithms and workflows to address this challenge. This article contains an overview of the software and some of its most heavily-used functionalities, including algorithmic details, standards, and examples. Key thrusts are highlighted: the calculation of structural, electronic, thermodynamic, and thermomechanical properties in addition to the modeling of complex materials, such as high-entropy ceramics and bulk metallic glasses. The aflow++ software prioritizes interoperability, minimizing the number of independent parameters and tolerances. It ensures consistency of results across property sets — facilitating machine learning studies. The software also features various validation schemes, offering real-time quality assurance for data generated in a high-throughput fashion. Altogether, these considerations contribute to the development of large and reliable materials databases that can ultimately deliver future materials systems. © 2022

As efforts to replace nonsustainable plastics increase, biocomposites from cellulose fibers and biodegradable polymers like poly(ε-caprolactone) (PCL) are promising candidates. The necessary adhesion between fibers and matrix can be achieved by grafting polymeric chains onto the fibers. Herein, we report grafting of PCL onto Abaca fibers (AFs), a one-pot method to obtain a composite containing grafted fiber and free PCL, and the characterization of prepared composite films. Three parameters for pretreatment (disintegration, drying, and solvent exchange) of AF were compared. Short and long PCL chains with molecular weights below and close to the chain entanglement weight of PCL were grafted from AFs. Using benzyl alcohol as an additional initiator, free PCL was simultaneously prepared. The unreacted monomer was removed by precipitation in water, resulting in ready-made one-pot composites. The biocomposites containing the free PCL and PCL-grafted AFs were further processed by a combination of compounding and hot-pressing. The analyzed mechanical (tensile) and rheological properties show a large dependence on the lengths of the PCL grafts. The herein-reported composites pave the way for interesting bio-based alternatives to plastic, especially looking at the tailoring of material properties. © 2021 The Authors.

Novel hybrid 2D class of ternary nanoheterostructures have been designed by mixing aluminium nitride (AlN), boron nitride (BN) with 2D graphene with the aim of designing innovative 2D nanoheterostructures for applications in electronics and other industries. The structural stability and electronic properties of these nanoheterostructures have been analysed using “first-principles based calculations done in the framework of density functional theory. Different structural patterns have been analysed to identify the most stable nanoheterostructures. It has been found to be more energetically favourable that the aluminium nitride and boron nitride atom chains occupy the positions of the carbon atoms in a clustered pattern in the nanoheterostructures. Carbon atom chains sandwiched between aluminium nitride and boron nitride chains of atoms is a preferred choice over isolated chains of BN, AlN and CC in the nanoheterostructures. The calculated band gaps of the novel nanoheterostructures are found to be 0.87, 0.43 and 0.65 eV respectively. These novel hybrid 2D nanoheterostructures are energetically favoured materials with both direct and indirect band gaps. They have potential applications in nanoscale semiconducting and optoelectronic devices, notably optical, optoelectronic and micro-electro-mechanical systems. © 2023 The Authors

Spin-optoelectronics plays a key role in developing next-generation technologies with potential applications covering from pharmaceutical synthesis and quantum computing to optical communication. One of the most feasible ways to achieve high-performance spin optoelectronic devices is based on chiral materials. Chiral metal-organic frameworks (CMOFs), an emerging class of chiral hybrid materials, have sparked interest due to their structural variety and flexibility, order nanopores, cost-effectiveness, and unique chirality features. Herein, we have developed CMOF [Sr (9,10-adc) (DMAc)2]n based on achiral building blocks [(9,10-adc)] to detect circularly polarized light (CPL) with ultrahigh sensitivity. Their application in spin-polarized flexible detectors gives a detectivity (D∗) as high as 1.83 × 1012 jones, superior to all reported heterochiral MOF-based detectors. Meanwhile, the anisotropy factor (gIph) is up to 0.38 for CPL detection. The maximum photoresponsivity (Rph) and photogain (η) values of CMOFs reach up to 6.0 × 105 (A/W) and 1.8 × 106, respectively, which are also the record values among reported chiral MOFs. Additionally, the photodetector is mechanically flexible and durable, manifesting an important feature for wearable devices. Therefore, our study shown here is significant and timely to open a route for advancing spin-optoelectronics based on CMOF. © 2023 Elsevier Ltd
