Pickering Emulsions with Long-Term Stability from Ultrafine Amphiphilic Benzyl-Modified Silica Nanoparticles

Abstract Pickering emulsions offer superior stability and eco-friendly properties across multiple industries due to solid particle stabilization at oil–water interfaces. However, the design and synthesis of ultrafine nanoparticles capable of stabilizing Pickering emulsions have a...

PolyAnalysis: a deep learning–based framework for nanopore-based poly(A) tail estimation and 3′-end regulation profiling

Abstract Background Polyadenylation at the 3′ end of mRNA regulates transcript stability, export, and translation, but poly(A) tail length and polyadenylation-site usage remain difficult to resolve from nanopore sequencing data because of homopolymer-associated errors and complex...

Bonding‐chemistry‐guided design of carbon frameworks for rechargeable‐ion batteries

Abstract Various carbon frameworks are central to rechargeable‐ion batteries, while continuous structural and compositional regulation provides broad opportunities to improve fast‐charging capability, storage capacity, and cycling stability. However, a unified chemistry‐based und...

Seismic control of two adjacent structures connected by an energy dissipation enhanced torsional eddy current damper: Optimum design and performance analysis

As urban space becomes increasingly constrained, structural spacing is often minimized within code-permitted limits, making closely spaced adjacent structures increasingly common. Under earthquakes, however, large relative motions between adjacent structures can increase the pote...

Highly Controllable Polarity in Two-Dimensional Vertical Transistors

Abstract Two-dimensional (2D) vertical transistors, featuring atomically thin channels and an inherent vertical architecture, hold extensive promise for ultrascaled electronics. However, achieving reliable polarity control in such devices has remained a persistent challenge over...

Experimental Investigation on Shear-Torsion Behavior of Geopolymer Concrete Beams and Modified Capacity Model from Apparent Stiffness Variation

Abstract Geopolymer concrete (GPC) is a promising low-carbon alternative to ordinary portland cement concrete (OPC). Its mechanical behavior differs from that of OPC, and existing models developed primarily for OPC do not accurately predict the behavior of GPC beams under combine...

Euthanasia and abandonment: Non-ideal theory, opportunity costs and financial incentives

Abstract: Recently, in Portugal, there have been several attempts by the parliament to pass a law that decriminalises euthanasia, and only the last one has passed. One of the arguments that have been raised against euthanasia, in the Portuguese context, is that euthanasia and med...

Whole-Process Integration and Economic Analysis of Postcombustion CO2 Capture with PZ-MDEA: From Experimental Validation to Industrial Application

Abstract Studying different absorbents and process configurations is crucial for the process performance of postcombustion CO2 capture, which can reduce the regeneration energy consumption of the stripper and improve the economics of the process. In this study, postcombustion CO2...

Design and performance analysis of a novel powertrain scheme for plug-in hybrid electric vehicles

This paper proposes a novel P2 hybrid transmission scheme integrating a converging-differential hydro-mechanical torque converter. This transmission enables continuous speed and torque regulation, allowing the hybrid system to achieve various operating modes with a single electri...

Point-line-plane topological thermal network constructed composite film with concurrent high thermal conductivity and electrical safety performance for electronic heat dissipation

The rapid miniaturization and high integration of high-power electronics exacerbate heat accumulation during operation, triggering device instability, shortened service life, and leakage or short-circuit hazards. Traditional carbon-based thermal interface materials (TIMs) suffer...

Succinate Ameliorates Sepsis‐Associated Acute Kidney Injury by Mediating Inflammation via GPR91

Succinate is a key metabolic intermediate in the tricarboxylic acid (TCA) cycle, which participates in energy metabolism. It accumulates under various pathological conditions and exerts regulatory effects through binding to its specific receptor GPR91. However, its specific funct...

Shear-transfer mechanisms in ultra-high-performance concrete beams reinforced by externally web-bonded steel plates

This study investigated a reinforced ultra-high-performance concrete (UHPC) beam in which conventional stirrups were replaced with externally web-bonded steel plates on the web (RUB-WSPs) to enhance the structural efficiency and construction productivity. To study the shear perfo...

Overcoming Cross-Sensitivity for the Accurate Identification of Acetone, Isopropanol, and Clinical Mixtures Using a MEMS Dual-Sensor Array and Multi-task Deep Learning

Abstract Accurate detection of exhaled acetone (ACE) and isopropanol (IPA) mixtures is critical for the non-invasive screening of diabetic ketoacidosis and the continuous monitoring of lipid metabolism in type 1 diabetes mellitus. However, the broad clinical application of this a...

Dynamic response of railway ballastless track-bed under various saturated conditions

Abstract Localised saturated zones formed within ballastless railway subgrades owing to rainfall infiltration and moisture accumulation may significantly alter the dynamic response of the track-bed under moving train loads. This study numerically investigates the influence of dif...

Breaking the Quality–Throughput Trade-Off: A Chaotic Microreactor Enabling Continuous Synthesis of High-Performance High-Entropy Prussian Blue Analogues

Abstract High-entropy Prussian blue analogues (HE-PBAs) for sodium-ion batteries face a quality–throughput trade-off: slow batch addition suppresses [Fe(CN)6]4– vacancies, whereas faster feeding increases defects and water. We develop a continuous recirculation chaotic microreact...

Energy transition and corporate geographic expansion

Accelerating the energy transition is pivotal to achieving sustainable economic development, yet localized environmental policies can profoundly reshape the spatial allocation of corporate capital. The impact of place-based energy transition policies on firms' cross-regional inve...
