Design Principles to Promote Acid–Base Interactions with a Weak Second-Sphere Lewis Acid

Abstract Boronic esters such as BPin are underutilized in secondary-sphere chemistry due to their weak acidity. We report a design strategy to enable cooperative binding with a BPin-appended NHC scaffold. Employing a shortened tether enhances preorganization and facilitates subst...

A functional basis for the developmental sequence of the macrostructure of the Venus flower basket ( Euplectella aspergillum )

Despite receiving significant interest from the biological and engineering communities, several questions about the underlying reasons for the form of the deep-sea sponge Venus flower basket (Euplectela aspergillum) remain unanswered. In particular, the basis for the sequence of...

Zwitterions with Fluorinated Anions: Design Principles for Tuning Phase Behavior

Abstract Zwitterions (ZIs) have attracted interest across electrolyte, separation, and materials applications. Unlike ionic liquids (ILs), zwitterions have both charges covalently tethered to a single backbone, a constraint that removes translational entropy from melting and allo...

Comparing Airbnb hosts’ and guests’ attitudes toward smart technology to support authenticity experiences

Purpose This study aims to examine how smart technology in peer-to-peer (P2P) accommodation may support, disrupt or reconfigure authenticity-related experiences. Focusing on Airbnb stays as a tension-laden hospitality context, it investigates how hosts’ intentions and guest-side...

Neurosymbolic code auditing

Code auditing examines whether an implementation satisfies target properties such as reliability, security, performance, and design intent. Classical static analysis provides rigorous foundations for automated auditing, but it remains difficult to apply broadly in real-world soft...

Quantum Dot-Induced Kinetic Bottleneck in Singlet Exciton Relaxation of Conjugated Polymer Aggregates

Abstract We designed hybrid aggregate model systems with cascade energy alignment from conjugated polymers (CPs) to quantum dots (QDs) to investigate the effects of QDs on CP singlet (S1) excitons. Radiative recombination of S1 excitons occurs within 1 ps in the chlorinated CP/QD...

ThermoPix: an electronic-photonic temperature sensor array with microsecond row readout

Abstract This paper presents ThermoPix, a CMOS-compatible electronic–photonic architecture for high-spatial-resolution temperature sensing. The proposed system converts temperature-induced wavelength shifts in a photonic interferometric sensor into timing information that can be...

Biphasic Self-Assembly of Chemically-Exfoliated MoS2 Monolayers into a MoS2/C Heterostructured Thin Film

Abstract Chemically exfoliated transition metal dichalcogenides are promising materials for optoelectronic applications, but their practical use is often limited by low in-plane electrical conductivity. Here, we report a biphasic self-assembly strategy for fabricating large-area...

Galectin-1 therapy recalibrates lipid remodeling in skeletal muscle and enhances muscle function in a model of LGMD2B/R2

Limb-Girdle Muscular Dystrophy type 2B/R2 (LGMD2B/R2) is a progressive myopathy caused by mutations in the DYSF gene, leading to dysferlin deficiency, impaired membrane repair, chronic inflammation, and lipid accumulation. No approved treatments currently exist. Galectin-1, a red...

How you read the text matters: Caregiver oral reading prosody during shared reading relates to preschoolers’ language skills

Acoustic features of child directed speech (CDS) in caregiver-child conversational interactions are known to capture young children’s attention to language input and facilitate language learning. Emerging evidence suggests that caregivers’ use of CDS-like features when reading to...

Nanofibrillated Cellulose–Regolith Composite Aerogels for Lunar Thermal Insulation

Abstract Life support systems in extraterrestrial settings face severe material constraints, demanding innovative in situ resource utilization (ISRU) strategies. One material that merits attention is cellulose, which can be procured in relative abundance from locally generated wa...

A Systematic Replication: Instructive Feedback to Produce Emerging Play Responses

Abstract Social deficits are common in children diagnosed with autism spectrum disorder (ASD). To help facilitate the development of social behaviors, practitioners may target specific play skills, such as with toys. Previous researchers have used discrete trial training (DTT) to...

Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)

Nitrogen-containing molecules are ubiquitous in pharmaceuticals, agrochemicals, and functional materials, making the development of efficient C─N bond-forming reactions a central goal in synthesis. Cobalt-catalyzed metal-hydride hydrogen atom transfer (Co─H/MHAT) has emerged as a...

Lease a battery electric vehicle now or later? An empirical analysis

While the battery electric vehicle (BEV) market faces uncertainty in the United States, especially regarding adoption timing, leasing has become a popular alternative to purchasing, accounting for approximately 60% of new BEVs in 2025. However, the literature rarely distinguishes...

A Nonasymptotic Theory of Seminorm Lyapunov Stability: From Deterministic to Stochastic Iterative Algorithms

We study the problem of solving fixed-point equations for seminorm-contractive operators and establish foundational results on the nonasymptotic behavior of iterative algorithms in both deterministic and stochastic settings. In the deterministic setting, we present a fixed-point...

Pressure-Driven Performance and Thermal Safety Tradeoff in Solid-State Batteries

Abstract Solid-state batteries (SSBs) offer high energy density and improved safety, but their performance is limited by poor particle contact and sluggish ion transport across solid–solid interfaces. External pressure improves electrochemical performance by enhancing interfacial...

Gestational heat stress and phytogenic supplementation influence sow growth, bioenergetics, thermoregulation, and subsequent offspring resilience

Abstract The study objectives were to determine whether a phytogenic supplement reduced physiological stress in heat-stressed (HS) gestating sows and to evaluate how HS alters maternal growth responses and postweaning growth and stress responses in their piglets. Twenty-six pregn...

Gender, descriptive representation, and the public legitimacy of international organizations

Abstract How does descriptive representation influence citizens’ perceptions of international organizations’ (IOs) legitimacy? While past work has investigated the impact of procedural and substantive dimensions on the legitimacy of IOs, the effect of descriptive representation r...
