Occupational Exposure to Airborne Bacteria During Handling Refuse-Derived Fuel from Municipal Solid Waste Used for Clinker Burning

Aerosol and Air Quality Research
Introduction Cement plants use refuse-derived fuel (RDF) as an important energy source in cement production. Objective The aim of the study was to characterize bacterial contamination of RDF and air at workplaces related to their combustion process ...

i‐Tac: Inverse Design of 3D‐Printed Tactile Elastomers with Tuneable Optical and Mechanical Properties

Advanced Intelligent Systems, EarlyView.
Inspired by the multi‐tissue architecture of the human fingertip dermis (A), this work introduces a mixture design using three PolyJet materials (AC/TM/GM) to expand the achievable elastomer property space (B). An inverse design pipeline (i‐Tac) is developed to map target optical/mechanical requirements to optimal material compositions (C), enabling ...

Robotic Arm‐Assisted Conformal 3D Printing of Displays for Structural Electronics

Advanced Intelligent Systems, EarlyView.
This study presents a robotics‐enabled platform combining 3D scanning and a 6‐DOF robotic arm for conformal printing on complex non‐planar structures. By maintaining nozzle perpendicularity, the system enables high‐fidelity direct ink writing on steep sidewalls, spherical surfaces, successfully demonstrating a fully printed 7‐segment dynamic display ...

Airborne Escherichia coli bacteria biosynthesize lipids in response to aerosolization stress

Scientific Reports
Gram-negative bacteria pose an increased threat to public health because of their ability to evade the effects of many antimicrobials with growing antibiotic resistance globally. One key component of gram-negative bacteria resistance is the functionality

Ice Initiation by Aerosol Particles: Measured and Predicted Ice Nuclei Concentrations versus Measured Ice Crystal Concentrations in an Orographic Wave Cloud [PDF]

, 2010
The initiation of ice in an isolated orographic wave cloud was compared with expectations based on ice nucleating aerosol concentrations and with predictions from new ice nucleation parameterizations applied in a cloud parcel model.

Effect of Budesonide Nasal Irrigation in Patients With Chronic Rhinosinusitis With Nasal Polyps Without Prior Sinus Surgery: A Randomized, Double‐Blind, Placebo‐Controlled Study

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background The indication for nasal irrigation with corticosteroids after sinus surgery in patients with Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) is well established, as surgery facilitates distribution throughout the sinonasal cavity.

Escherichia coli resistance mechanism AcrAB-TolC efflux pump interactions with commonly used antibiotics: a molecular dynamics study

Scientific Reports
While antibiotic resistance poses a threat from both Gram-positive bacteria (GPB) and Gram-negative bacteria (GNB), GNB pose a more imminent public health hazard globally. GNB are a threat to growing antibiotic resistance because of the complex makeup of

On the implications of aerosol liquid water and phase separation for modeled organic aerosol mass [PDF]

, 2016
Water is an important component of PM2.5 Many traditional SOA species are highly soluble and thus can be considered extractable Water can influence the partitioning of compounds traditionally considered insoluble in models Organic aerosol takes up water ...

Highly Time-Resolved Elemental Source Apportionment at a Prague Urban Traffic Site

Aerosol and Air Quality Research
Positive Matrix Factorization was used for source apportionment of 2-hour online metals (Xact625i; PM2.5) and elemental and organic carbon (EC/OC analyser; PM1) data at an urban traffic site in Prague, Czech Republic, for two month-long periods in spring
