Designing Scalable Mechano‐Virucidal Nanostructured Acrylic Surfaces for Enhanced Viral Inactivation

open access: yesAdvanced Science, EarlyView.
Can a surface be designed to physically break viruses? This study explores how nanoscale geometry—specifically the spacing of tiny pillars—can determine whether viruses remain intact or rupture. Using flexible acrylic and a scalable fabrication process, the authors develop nanopillared, transparent surfaces that show strong antiviral activity without ...

Customizing Tactile Sensors via Machine Learning‐Driven Inverse Design

open access: yesAdvanced Science, EarlyView.
ABSTRACT Replicating the sophisticated sense of touch in artificial systems requires tactile sensors with precisely tailored properties. However, manually navigating the complex microstructure‐property relationship results in inefficient and suboptimal designs.

Programmable‐Stiffness Tensegrity Continuum Robot for Adaptive Multicurvature On‐Orbit Assembly

open access: yesAdvanced Intelligent Systems, EarlyView.
A bioinspired tensegrity‐based continuum robot (BTCR) with programmable stiffness enables adaptive multicurvature morphing via coordinated intra‐ and intermodule regulation. A unified energy‐based framework predicts self‐equilibrium and deformation for serial modules. Experiments and Simulations demonstrate reconfiguration into hexagonal, circular, and

Excitation Requirement For Rectified Output AC Generators [PDF]

open access: yes, 1970
This paper develops a method for calculating the required dc field current of a three-phase synchronous ac generator for known dc load conditions and machine characteristics. The method is simple to apply and has shown good agreement with test data.

Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen‐rewarding Caribbean bloodwort

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Phylogenomics, ecomorphological evolution, and historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae)

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

Echoes of Gordon Craig in the Romania of the 1930s and 40s [PDF]

open access: yesStudii si Cercetari de Istoria Artei : Teatru, Muzică, Cinematografie, 2012
Europe between the two world wars was marked by contradictions and intense quests. In the world that emerged from the first global conflagration, Romania found itself at the border zone between the new post-revolutionary Soviet state, with its growing ...

The Voice of Cantú: Lower Voice Pitch Is a New Phenotypic Feature of Cantú Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Cantú syndrome (CS) is a rare genetic condition caused by pathogenic variants in either ABCC9 or KCNJ8, leading to gain‐of‐function of KATP‐channels. The main clinical features are hypertrichosis and cardiovascular abnormalities. This study investigates the voice characteristics in individuals with CS, an aspect that has received little ...

Evaluation of Air Inlet Configuration's Effect on Biochar Properties From African Mesquite Pod Carbonization

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The suboptimal efficiency of current biomass conversion processes necessitates the optimization of biochar production methodologies to enhance desired biochar characteristics. In this study, an investigation was conducted to determine the optimal air inlet configuration within a top‐lit updraft gasifier system for enhancing biochar properties ...
