Metatranscriptomic Sequencing of a Cyanobacterial Soil-Surface Consortium with and without a Diverse Underlying Soil Microbiome. [PDF]

open access: yes, 2020
Soil surface consortia are easily observed and sampled, allowing examination of their interactions with soil microbiomes. Here, we present metatranscriptomic sequences from Dark Green 1 (DG1), a cyanobacterium-based soil surface consortium, in the ...

Smart Nanogels as Enzyme‐Driven Nanomotors for Navigating Viscous Physiological Barriers

open access: yesAdvanced Functional Materials, EarlyView.
Two families of urease‐powered nanomotors (NMs), with and without a p‐(2‐hydroxyethyl methacrylate) (p‐HEMA) shell, have been successfully prepared. Both types exhibit effective motion in highly viscous synovial fluid media at low urea concentrations (25 mM).

Reverse-osmosis membranes by plasma polymerization [PDF]

open access: yes, 1972
Thin allyl amine polymer films were developed using plasma polymerization. Resulting dry composite membranes effectively reject sodium chloride during reverse osmosis.

DENTA: A Dual Enzymatic Nanoagent for Self‐Activating Tooth Whitening and Biofilm Disruption

open access: yesAdvanced Functional Materials, EarlyView.
The nanoapatite with dual enzymes (DENTA) accumulates in dentinal tubules, reducing hypersensitivity caused by dental nerve exposure and facilitating continuous ROS generation through salivary glucose for effective, long‐term whitening. The dentin structures remain non‐destructive due to the low concentration of ROS, demonstrating excellent cell ...

Rice and fertilizer policies in Indonesia : a thesis presented in partial fulfillment of the requirements for the degree of Masters of Agricultural Economics, Massey University [PDF]

open access: yes, 1993
To promote rice production, the government of Indonesia implemented various agricultural policies. Some agricultural inputs had been subsidised heavily, particularly fertilizers.

Catalytic TiO2 with Self‐Assembled Monolayer for Highly Sensitive, Selective, and Non‐Invasive Monitoring of Sweat L‐Cysteine

open access: yesAdvanced Functional Materials, EarlyView.
A self‐assembled monolayer of 3‐mercaptopropyltrimethoxysilane (MPTS) molecular receptor and titanium oxide‐modified carbon cloth (MPTS/TiO2/CC) was synthesized for the specific detection of sweat L‐cysteine, which is associated with the precision neutrition, cardiovascular system and neuro system.

Sensing of Chloride Ions in Sweat by Means of Printed Extended‐Gate Organic Electrochemical Transistors

open access: yesAdvanced Functional Materials, EarlyView.
In this work, a platform based on an Extended‐Gate OECT is successfully developed and tailored for the detection of physiologically relevant chloride ion concentrations in artificial eccrine sweat. Leveraging the extended‐gate architecture, a high‐performance OECT based on inkjet‐printed pg2T‐TT is coupled with an inkjet‐printed Ag/AgCl electrode ...
