Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications
Advanced Materials Technologies, EarlyView.Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

Patterned Screen‐Printing Process for Substrate‐Free and Scalable Hyaluronic Acid Microneedle Arrays
Advanced Materials Technologies, EarlyView.A substrate‐free microneedle array comprising a hybrid hyaluronic acid ink was fabricated via a scalable screen‐printing process for flexible transdermal drug delivery. Defect‐free mold filling was achieved using a vacuum‐assisted jig and a delayed drying system, and the use of this versatile platform for multi‐drug patterning and ex vivo skin ...

Physicochemical Analysis of Neotropical Soils
, 2020 In archaeological contexts, physicochemical soil analyses are essential to distinguish between the anthropogenic characteristics of the soil and those resulting from soil formation processes. This involves several physicochemical characterisations of samples, which have been used since the first half of the last century in various regions of the world,

A physicochemical analysis of conjugation in Tetrahymena pyriformis
Experimental Cell Research, 1976Abstract The process of conjugation in Tetrahymena pyriformis is a useful model system for investigating mechanisms of cellular recognition, adhesion and fusion. As a first step in the biochemical analysis of this process, we have examined the effects of (a) nutrients; (b) metal ions; (c) several pharmacological agents (actinomycin D, cycloheximide ...

Physicochemical Properties and Toxicity Analysis
2021In this chapter, we explore various chemical interactions as well as modifications of graphene-based nanomaterials (mostly carbon dots and graphene quantum dots) toward enhancement of their properties. The properties include optical, photophysical, and chemical that determine their modifications for various applications.

Physicochemical Analysis of Wheat Starch
1992Starch occurs as water-insoluble granules which are partially crystalline and birefringent when viewed between crossed polars. Wheat grains contain two main populations of granules, the larger A-type granules are formed early in seed development and have a major dimension ranging from 10–35 μm, the smaller B-type granules are formed later in ...
