Effects of Proteins from Culture Medium on Surface Property of Silanes- Functionalized Magnetic Nanoparticles

open access: yesNanoscale Research Letters, 2008
Monodisperse magnetic nanoparticles (MNPs) were synthesized by thermal decomposition of iron-oleate and functionalized with silanes bearing various functional groups such as amino group (NH2), short-chain poly(ethylene glycol) (PEG), and carboxylic group

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Optimizing Blood Pressure Control: A Randomized Comparative Trial of Losartan/Chlorthalidone vs. Losartan/Hydrochlorothiazide

open access: yesCardiology and Therapy
Introduction Cardiovascular diseases are a leading cause of global mortality, with hypertension as a major risk factor. Low control rates are often attributed to monotherapy, while evidence and clinical guidelines support the effectiveness of combination

Comparative investigations of silanes in UN Test O.2 (liquid oxidizer)

open access: yesResults in Chemistry
Decachlorotetrasilane, octachlortrisilane and hexachlorodisilane show false-positive results in the UN Test O.2 (liquid oxidizer). The cause of this unexpected result had been explained in former investigations.

Multifunctional Microstructured Surfaces by Microcontact Printing of Reactive Microgels

open access: yesAdvanced Functional Materials, EarlyView.
Reactive poly(N‐vinylcaprolactam‐co‐glycidyl methacrylate) microgels are used as functional inks to create surface‐grafted arrays on glass via microcontact printing. The patterns (10–50 µm widths and spacings) enable stable binding and post‐functionalization with dyes and peptides.

High‐Spatiotemporal‐Resolution Transparent Thermoelectric Temperature Sensor Arrays Reveal Temperature‐Dependent Windows for Reversible Photothermal Neuromodulation

open access: yesAdvanced Functional Materials, EarlyView.
Thermoelectric temperature sensors are developed that directly measure heat changes during optical‐based neural stimulation with millisecond precision. The sensors reveal the temperature windows for safe reversible neural modulation: 1.4–4.5 °C enables reversible neural inhibition, while temperatures above 6.1 °C cause permanent thermal damage.

Early-Age Properties and Reaction of Hydrophobic Portland Cement and Alkali-Activated Fly Ash–Slag Pastes with Alkyl Silanes

open access: yesBuildings
Cementitious materials are susceptible to water ingress due to their hydrophilicity and porous microstructure, which can cause premature destruction and compromise long-term durability.
