Human hair is a keratin-based fiber with mechanical properties relevant to load-bearing biomaterials; however, its smooth cuticle limits fiber-fiber cohesion during textile-style processing. This study examines how controlled chemical decuticularization influences surface morphology and tensile behavior of intact human…

The activated bleaching clay is used at high temperatures and for extended periods to eliminate pigments and remove impurities from oils through physical and chemical interactions. However, the use of acid-activated clay in industrial oil bleaching (IB) presents several drawbacks: prolonged filtration times due to the…

Background Dental bleaching is the most common method for managing tooth discoloration, and several light sources have been investigated for accelerating the bleaching process. However, various wavelengths of lasers revealed high effectiveness in tooth color whitening compared to conventional bleaching. This in-vitro…

To generate a comparative spatial proteomic atlas of the human and mouse retina using a refined highly multiplexed immunohistochemistry technique called Iterative Bleaching Extends Multiplexity (IBEX). We refined the IBEX workflow by integrating an antibody removal option alongside chemical bleaching. This dual…

Coral gastrovascular cavities (GVCs) host diverse microorganisms and, as semi-closed compartments, are characterized by elevated nutrient concentrations and pronounced diel fluctuations in oxygen (O2) and pH. However, their broader chemical microenvironment and associated microbial activities remain poorly understood.…

Coral, as a bioreactor, has to continuously interact with surrounding environment to maintain a healthy state. A multi-physics reaction engineering model has been developed to capture this interaction. The coral interior is modeled as interconnected reaction units respectively for photosynthesis, respiration, and…

Fluorescence imaging with spectrally variant fluorophores allows the spatial mapping of biological structures with exquisite cellular and molecular specificity. However, the ability to robustly discriminate multiple fluorophores in any single imaging experiment is greatly hindered by the broad emission spectra of…

Mesoscopic brain imaging, enabled by advances in tissue clearing, light-sheet microscopy, and large-scale image processing, allows detailed analysis of cellular and molecular architecture across whole neural circuits. However, applying these methods to postmortem human brain tissue is hindered by strong…

Coral bleaching is a major concern for marine ecosystems; more than half of the world's coral reefs have either bleached or died over the past three decades. Increasing sea surface temperatures, along with various spatiotemporal environmental factors, are considered the primary reasons behind coral bleaching. The…

Quaternary ammonium compounds (QACs) have been used as antimicrobial additives in textiles, but information on the environmental occurrence of QACs in textiles and their ecological impacts from laundry wastewater is scarce. In this study, we purchased 119 textile samples from Chinese online vendors, with the product…
