Comparison of three distinct surgical clothing systems for protection from air-borne bacteria: A prospective observational study

open access: yesPatient Safety in Surgery, 2012
Background To prevent surgical site infection it is desirable to keep bacterial counts low in the operating room air during orthopaedic surgery, especially prosthetic surgery.

Multistackable, Domino‐Overlapped CNT Scaffolds Homogeneously Hybridized with BTO‐P(VDF‐TrFE) for High‐Performance Piezoelectric Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
A multilayer‐stackable carbon nanotuber (CNT) scaffold‐based piezoelectric nanogenerator (CPENG) with domino‐patterned CNT pillars presents high, stable output (12.3 V, size of 1 cm × 1 cm) over 2000 cycles, operates across a wide temperature range, and efficiently converts energy from real‐life stimuli through optimized CNT length, layer stacking, and

A brief history of medical uniforms: from ancient history to the COVID-19 time

open access: yesRevista do Colégio Brasileiro de Cirurgiões
Medical Uniforms date back from medieval times. Nursing uniforms were based on nuns clothes whereas doctors used the famous “plague costumes” and black “frock” coats from about 15th to early 19th century.

Predicting the cognitive correlates of sun protective behaviour : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in Psychology at Massey University [PDF]

open access: yes, 1999
Previous research has explored the cognitive correlates of sun protective behaviour and has found that intention to use skin protection is likely to affect an individuals decision to use such behaviour.

Geometrically‐Screened, Sterically‐Hindered Additive for Wide‐Temperature Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A molecular‑engineering strategy combining steric hindrance tuning with geometric optimization identifies cellobiose as an ideal additive for aqueous zinc‑ion batteries, enabling stable Zn deposition across a wide temperature range from −30 to 50 °C. Abstract Aqueous zinc‐ion batteries (AZIBs) are emerging as a highly promising alternative to lithium ...

Upcycling of Disposable Face Masks into Water‐Resistant and Flame Retardant Foams

open access: yesAdvanced Functional Materials, EarlyView.
Disposable mask waste is upcycled into lightweight polypropylene‐based foams with tunable porosity and composite architectures reinforced by ear‐loop fibers. The sustainable solvent‐based process enables upcycling rates of 91% and solvent recovery of >90%.

All‐Aqueous Pullulan Fibers Enabling Visible‐to‐Near‐Infrared Waveguiding with Mechanical and Thermal Resilience

open access: yesAdvanced Functional Materials, EarlyView.
Pullulan, a biomass‐derived polysaccharide, is transformed into transparent optical fibers using a solvent‐free borax hydrogel‐spinning method. The fibers outperform PMMA with ≈200 MPa tensile strength and 200 °C stability, while uniquely guiding visible‐to‐NIR light and enabling additive‐free humidity sensing.

Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation

open access: yesAdvanced Functional Materials, EarlyView.
This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

Oral application of L-menthol in the heat: From pleasure to performance [PDF]

open access: yes, 2019
When menthol is applied to the oral cavity it presents with a familiar refreshing sensation and cooling mint flavour. This may be deemed hedonic in some individuals, but may cause irritation in others.
