title: Energy digital twin technology for industrial energy management: Classification, challenges and future

authors: Yu, Wei

subjects: software engineering

abstract: Digitalisation of the process and energy industries through energy digital twin technology promises step-improvements in energy management and optimisation, better servicing and maintenance, energy-efficient design and evolution of existing sites, and integration with locally and regionally generated renewable energy. This systematic and critical review aims to accelerate the understanding, classification, and application of energy digital twin technology. It adds to the literature by developing an original multi-dimensional digital twin classification framework, summarising the applications of energy digital twins throughout a site's lifecycle, and constructing a proposal of how to apply the technology to industrial sites and local areas to enable a reduction in carbon and other environmental footprints. The review concludes by identifying key challenges that face uptake of energy digital twins and a framework to apply the energy digital twins.

title: Isopolyoxometalates derived from arylstibonic acids with "reverse-Keggin ion" structures based on [M(RSb) ₁₂O ₂₈] cores, M = Co(ii) or Zn(ii).

authors: Nicholson, Brian K.

subjects: Keggin ions

abstract: The preparations and structures are described of four new polyoxostibonates, [Co(p-MeC ₆H ₄Sb) ₁₂O ₂₈{Co(H ₂O) ₃} ₄]Cl ₂₋ 6H ₂O, [Co(p-ClC ₆H ₄Sb)₁₂O ₂₈{Co(H ₂O) ₃} ₄]Cl₂₋ 22H ₂O, (PhCH ₂NMe ₃) ₂[Zn(p-ClC ₆H ₄Sb) ₁₂O ₂₈Zn ₄Cl₂•₅₄ Br ₁•₄₆]•8MeCN•H ₂O and [BaCoH ₄(p-MeC ₆H ₄Sb)O ₂₈] •5H₂O. Each of these has a framework of 12 (RSb) groups linked by 28 O atoms, with one transition metal ion in a tetrahedral site in the centre. Other metal ions are coordinated to the polyhedral faces. Three of the complexes have the ε Keggin ion geometry, while the fourth is a δ isomer.

title: AI: a new (r)evolution or the new colonizer for Indigenous peoples?

authors: Whaanga, Hēmi

abstract: We are often told that there is one constant in life and that is change; it is inevitable, inescapable. When the forces of power begin to blow and conditions are right, change will happen. As the planet undergoes a period of transformation brought about by the advances of data science and the convergence of technologies, the Internet of All Things and AI, the potential of AI to be change agent for Indigenous peoples is a thought-provoking, and to a certain degree, daunting proposition. The rapid progress of technology and innovation, in terms of its volume, complexity, and exponential growth in computing power, have drastically changed how we socialize, communicate, access, share, distribute and view knowledge and information. Is AI inevitable, inescapable, a fait accompli for Indigenous peoples?
