Atmospheric Pressure Plasma Jet Treatment of Human Hair Fibers [PDF]

open access: yesJournal of Bio- and Tribo-Corrosion, 2015
Human hair fibers in virgin and dyed forms were treated with atmospheric pressure helium, helium/oxygen, argon, and argon/oxygen plasma jets at 20 W of power. The effects of 10-min plasma treatment on surface morphology and chemistry were studied by scanning electron microscopy and X-ray photoelectron spectroscopy, respectively.

A replication study confirmed the EDAR gene to be a major contributor to population differentiation regarding head hair thickness in Asia [PDF]

open access: yes, 2008
Hair morphology is a highly divergent phenotype among human populations. We recently reported that a nonsynonymous SNP in the ectodysplasin A receptor (EDAR 1540T/C) is associated with head hair fiber thickness in an ethnic group in Thailand (Thai-Mai ...

Optimization of Drilling Parameters in Sisal-Human Hair Hybrid Composite Using Grey Relational Analysis

open access: yesAdvances in Materials Science and Engineering, 2022
Sisal is the most commonly used natural fiber in polymer composites due to its high strength, durability, and ability to stretch. In this present work, sisal and human hair were used as reinforcement for epoxy resin-based hybrid composites, and their ...

Insights on the Hair Keratin Structure Under Different Drying Conditions

open access: yesJournal of Natural Fibers, 2023
It is important to understand the patterns of hair keratin integrity caused by drying methods. No previous information exists in the literature to compare different drying conditions needed to assess physical changes in the hair keratin.

Morphology Analysis of Hair Photoinduced and Chemical Damaged After Treatment with Sappan Wood (Caesalpinia sappan L.) Hair Tonic using SEM

open access: yesBorneo Journal of Pharmacy, 2023
Exposure to sunlight for a long time and repeatedly can also cause chemical and physical damage to human hair. Clinically, microscopic analysis using a scanning electron microscope (SEM) can assess hair damage by identifying the characteristic ...

Investigation of human hair fibers using lateral force microscopy

open access: yesScanning, 2001
AbstractAtomic force microscopy (AFM) and lateral force microscopy (LFM) were used to investigate the morphologic and surface changes associated with various surface modifications to human hair. These included extraction with a series of solvents, bleaching, and treatment with a cationic copolymer.

A computer model of auditory efferent suppression: Implications for the recognition of speech in noise [PDF]

open access: yes, 2010
The neural mechanisms underlying the ability of human listeners to recognize speech in the presence of background noise are still imperfectly understood.

Human pollution exposure correlates with accelerated ultrastructural degradation of hair fibers [PDF]

open access: yesProceedings of the National Academy of Sciences, 2019
Significance Air pollution via phototoxic polycyclic aromatic hydrocarbons (PAHs) is a major risk factor for human health. While in vitro observations and in vivo correlations suggest a detrimental effect of PAHs at physiological concentrations, in vivo observations of the structural impact of PAHs are scarce.

Valorization of keratin biofibers for removing heavy metals from aqueous solutions [PDF]

open access: yes, 2018
Four common waste keratin biofibers (human hair, dog hair, chicken feathers, and degreased wool) have been used as biosorbents for the removal of heavy metal ions from aqueous solutions. Different parameters of the biosorption processes were optimized in
