Colossal and fully reversible barocaloric effect for sustainable cooling in a pressure-sensitive spin-crossover complex
Abstract Barocaloric refrigeration has great potential to replace traditional vapor-compression systems, which are conspicuously harmful to the environment. Investigating barocaloric effect driven by a practical pressure remains challenging.
Toward federated large language models in medicine: a parameter-efficient framework for privacy-preserving, multi-institutional adaptation
Abstract Large language models (LLMs) are increasingly adapted for medical applications, but most are trained using data from a single institution because privacy and governance constraints prevent multi-institutional data sharing. As a result, these models often generalize poorly across heterogeneous healthcare systems. We address this gap by introducing Fed-MedLoRA and Fed-MedLoRA + , a parameter-efficient federated framework for collaborative LLM adaptation across healthcare institutions.
A superelastic titanium alloy showing nearly temperature-independent high strength and elastic modulus
Abstract Lightweight superelastic alloys with temperature-insensitive properties are critical for deep-space exploration devices, yet their development is hindered by the challenge of simultaneously balancing strength, recoverable strain, and temperature sensitivity. Here, we overcome these limitations in a Ti50.5Zr40Nb6Sn2O1.5 alloy through Zr/O co-doping to induce local chemical orders (LCOs).
Spatiotemporally coupled sulfur chemistry for stable silicon-90+ anodes
Abstract Silicon-based materials stand as tantalizing battery anodes for markedly advancing performance indicators of today’s rechargeable lithium-ion batteries; however, their structural degradations, together with detestable side reactions residing in electrode-electrolyte interphases, greatly hinder the delivery of energy promises under practical conditions.
Calibration-free 3D imaging through scattering media via diffusion-kernel-guided reconstruction
Three-dimensional (3D) imaging based on the diffusion equation typically requires prior knowledge of the medium’s thickness and optical properties, thereby limiting its practical applicability. We present a calibration-free 3D imaging framework that overcomes this limitation.
Coherent twins for manufacturing thick lithium-rich battery positive electrodes
Abstract Thick electrodes are a key strategy for enhancing the energy density of non-aqueous lithium-based batteries. However, their practical application is hindered by sluggish ion transport, reaction inhomogeneity and mechanical degradation. Lithium-rich layered oxides offer a high theoretical specific capacity via anionic charge compensation, yet, from a practical perspective, they suffer from nanoscopic structural stress, oxygen redox irreversibility and electrode-scale transport limitations.
Fast formation to reinforce lithium-rich cathodes
Abstract Formation in lithium-ion battery manufacturing typically involves low-rate charge–discharge cycles to establish stable electrode–electrolyte interfaces—a time-consuming process1,2,3,4. Here, our findings on lithium-rich layered oxide cathodes challenge the necessity of conventional formation, which can even shorten battery lifespan. Fast formation, on the other hand, reduces production cost and enhances capacity and stability.

Investigating the structural evolution of lithium zirconium nitrochloride solid electrolytes for all-solid-state batteries
Abstract All-solid-state batteries with inorganic solid electrolytes are a global trend in the development of next-generation energy storage devices, promising greatly simplified designs, increased energy density, and, perhaps most importantly, enhanced safety. Currently, the anion-mixed strategy for all-solid-state batteries is the mainstream for developing amorphous halide solid electrolytes, opening up good possibilities for creating conductors with high ionic conductivity and stability.
Machine learning-assisted high-throughput screening of superlattice-like O-PCM thin films
Abstract Non-volatile optical phase change materials with superlattice-like structures (O-PCMs-SLL) offer transformative application potential for photonic integration with low optical loss and enhanced thermal stability. However, the optimization of O-PCMs-SLL is complicated by a high-dimensional design space in which key structural parameters (e.g., modulation period, layer thickness, deposition sequence) exhibit complex interdependencies.
Elinvar Materials: Recent Progress and Challenges
1 Introduction The elastic modulus (E), a fundamental material property describing resistance to an elastic deformation under external strain, is critical for emerging technologies such as artificial muscles and protective shielding in aerospace applications [1, 2]. Achieving precise control of elastic modulus E requires not only tuning its magnitude, but also ensuring an invariable elastic modulus with temperature—a phenomenon known as the Elinvar effect [3].
Orientation-dependent mutual crystalline and amorphous order in a single phase solid - Nature Communications
Abstract Amorphous materials distinguish themselves from crystalline materials by lacking long-range order while retaining structural order at the local scale (2–5 Å). However, the complexity in topological and chemical order prevents current characterization tools from fully unveiling the structure in disordered materials. Consequently, the nature of medium-range order in amorphous materials has remained elusive.
AI-enabled learning analytics use relates to physical literacy and engagement in university PE via smart teaching and personalised feedback - Scientific Reports

Structured liquid-based reconfigurable all-liquid optical fibers - Nature Communications
Abstract Quartz optical fibers are brittle, difficult to repair, and lack reconfigurability, limiting their adaptability in underwater communication. To overcome these impediments, here we show reconfigurable all-liquid optical fibers (RAOFs) produced by structured liquid, tuned by the interfacial assembly and jamming of nanoparticle surfactants at the water-oil interface (interfacial tension <10 mN m-1, refractive index contrast of 0.083).
Fucosyltransferase 8‐Derived Circular RNA Drives M2 Polarization of Macrophages Through ENO1‐TNF Signaling Axis to Promote Lung Cancer Progression
1 Introduction Lung cancer is a leading cause of cancer-related mortality, with non-small cell lung cancer (NSCLC) comprising approximately 85% of all lung cancer cases [1]. Within NSCLC, lung adenocarcinoma (LUAD) is the most common subtype, representing about 60% of NSCLC cases [2, 3]. LUAD often lacks distinctive clinical features, leading to a high recurrence rate and low survival rate [4]. In contrast, LUSC is more prevalent among smokers and has a poor prognosis despite advances in treatment.

Large thermoelastic effect in martensitic phase of ferroelastic alloys for high efficiency heat pumping - Nature Communications
Abstract Solid state heat pumping using latent heat from first order ferroic phase transitions is a promising green alternative to traditional vapor compression technology. However, the intrinsic phase transition hysteresis poses a limitation on heat pumping energy efficiency. Here, we propose heat pumping using reversible heat from anhysteretic elastic deformation in martensitic phase of ferroelastic alloys. Conventionally, this thermoelastic effect (TeE) is considered too weak to be practical.

Harnessing instability for work hardening in multi-principal element alloys - Nature Materials
Abstract The strength–ductility trade-off has long been a Gordian knot in conventional metallic structural materials and it is no exception in multi-principal element alloys. In particular, at ultrahigh yield strengths, plastic instability, that is, necking, happens prematurely, because of which ductility almost entirely disappears.

Electrolyte-assisted low-voltage decomposition of Li2C2O4 for efficient cathode pre-lithiation in lithium-ion batteries
Electrolyte-assisted low-voltage decomposition of Li2C2O4 for efficient cathode pre-lithiation in lithium-ion batteries Lithium oxalate (Li2C2O4) is an appealing cathode pre-lithiation additive for lithium-ion batteries (LIBs) but is hindered by high decomposition potential (>4.7 V). Under the liquid-solid synergistic effect of NaNO2 additive and LiNi0.83Co0.07Mn0.1O2 (NCM) cathode material, the decomposition efficiency of the miro-Li2C2O4 reaches 100% at the low charge cutoff voltage 4.3 V.

Giant uniaxial negative thermal expansion in FeZr2 alloy over a wide temperature range - Nature Communications
Abstract Negative thermal expansion (NTE) alloys possess great practical merit as thermal offsets for positive thermal expansion due to its metallic properties. However, achieving a large NTE with a wide temperature range remains a great challenge. Herein, a metallic framework-like material FeZr2 is found to exhibit a giant uniaxial (1D) NTE with a wide temperature range (93-1078 K, \({\bar{\alpha }}_{l}=-34.01\times {10}^{-6}\,{{{{{{\rm{K}}}}}}}^{-1}\)).
A Li-rich layered oxide cathode with negligible voltage decay - Nature Energy
Abstract With high capacity at low cost, Li- and Mn-rich (LMR) layered oxides are a promising class of cathodes for next-generation Li-ion batteries. However, substantial voltage decay during cycling, due to the unstable Li2MnO3 honeycomb structure, is still an obstacle to their practical deployment. Here we report a Co-free LMR Li-ion battery cathode with negligible voltage decay.

The nonopioid cholinergic agonist GTS-21 mitigates morphine-induced aggravation of burn injury pain together with inhibition of spinal microglia activation in young rats
Repetitive opioid use does not always alleviate basal pain, procedural pain, or both after burn injury. Mitigation of burn injury-site pain can be achieved by GTS-21 stimulation of α7-acetylcholine nicotinic receptors (α7AChRs) and reduced microglia activation in rat. We tested the hypothesis that morphine exaggerates burn injury-site pain and GTS-21 alleviates both morphine-induced aggravated burn injury pain and microglia activation.

A high-energy and long-cycling lithium–sulfur pouch cell via a macroporous catalytic cathode with double-end binding sites - Nature Nanotechnology
Abstract Lithium–sulfur batteries are attractive alternatives to lithium-ion batteries because of their high theoretical specific energy and natural abundance of sulfur. However, the practical specific energy and cycle life of Li–S pouch cells are significantly limited by the use of thin sulfur electrodes, flooded electrolytes and Li metal degradation. Here we propose a cathode design concept to achieve good Li–S pouch cell performances.
