Bioinspired, Mitochondria‐Targeted Single‐Atom Nanozyme Enhances Bone Regeneration by Reprogramming Stem Cell Energy Metabolism​

Advanced Materials, EarlyView.
A bioinspired nanozyme—triphenylphosphonium (TPP)‐dendritic mesoporous silica nanoparticle (DMSN)‐Fe/Cu—mimics mitochondrial complex IV and targets mitochondria to regulate cellular energy metabolism. This approach markedly boosts bone regeneration in vivo, as demonstrated by enhanced bone volume and mineral density in critical‐sized bone defects rat ...

A global analysis of expected revenues from carbon dioxide removal

Environmental Research Letters
Carbon dioxide removal (CDR) must scale rapidly to achieve net-zero emissions by mid-century. This scale-up requires substantial investment in the CDR industry, underpinned by stable revenues.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing

Advanced Materials, EarlyView.
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

Advanced Separators for Liquid and Quasi‐Solid Lithium Rechargeable Batteries: Design and Development

Advanced Materials, EarlyView.
This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...

From laggard to leader: explaining offshore wind developments in the UK [PDF]

, 2013
Offshore wind technology has recently undergone rapid deployment in the UK. And yet, up until recently, the UK was considered a laggard in terms of deploying renewable energy. How can this burst of offshore wind activity be explained?

Composition Restoration Enables Recycling of Mixed‐Cation, Mixed‐Halide Perovskites for Solar Cells

Advanced Materials, EarlyView.
Compositional drift during processing prevents the direct recycling of mixed‐cation, mixed‐halide perovskites. This work introduces a framework to quantitatively audit and restore recovered materials, enabling closed‐loop recycling with efficiencies comparable to virgin perovskites.

Tribal communities and coal in Northeast India: The politics of imposing and resisting mining bans [PDF]

, 2016
Bans on coal mining have been implemented in two tribal majority states in India's north-east frontier; Nagaland and Meghalaya. In Nagaland the state government imposed the ban in an attempt to capture control of coal extraction and trade, while in ...
