Driving Drugs Deeper: Force‐Driven Microneedle Systems for Active Therapy and Their Road Towards Clinical Implementation

open access: yesSmall, Volume 22, Issue 55, 1 October 2026.
Force‐driven microneedles are presented as active therapeutic microdevices that overcome the diffusion limits of conventional patches. By integrating gas generation, magnetic actuation, cavitation, or iontophoresis, these systems drive payloads deeper into tissue, enabling faster, more controlled delivery and highlighting key design principles and ...

Effects of Binder Content and Dispersion Strategy on Porosity in Extrusion Additive Manufacturing of ZrB2–SiC Ceramic

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 5, October 2026.
ABSTRACT This study examined the effects of binder content and dispersion on aqueous ZrB2–SiC ceramic paste and the porosity of ZrB2–SiC ceramic parts fabricated using an extrusion‐based additive manufacturing process. An aqueous paste of ZrB2–SiC (70/30 by volume) powder with a 45 vol.% solids loading and hydroxypropyl methylcellulose as the binder ...

Characteristics Of The Reciprocating Pump

open access: yes, 1988
Tutorialpg. 163A discussion is presented on the physical differences between centrifugal pumps and reciprocating pumps. The disparities are explained in a nonbiased manner and such knowledge should precede an introduction to reciprocating pump basics ...

Temperature dependence of HCN channel kinetics: A systematic comparison across mammalian isoforms and species

open access: yesExperimental Physiology, Volume 111, Issue 10, Page 4659-4687, 1 October 2026.
Abstract Hyperpolarization‐activated, cyclic nucleotide‐gated (HCN) channels are important regulators of cardiac pacemaking and neuronal excitability, yet their temperature dependence has not been compared systematically across mammalian isoforms and species in standardized experimental conditions. Here, we performed a standardized electrophysiological

Seismic and Aseismic Slip Compete to Regulate Permeability Evolution During Fault Reactivation

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Crustal permeability can be created through microearthquakes as observed at field and laboratory scales. The respective roles of seismic and aseismic slip in governing permeability evolution remain ill‐constrained. Here, we present observations of controlled pore pressure stepping experiments designed to distinguish the separate influences of ...

Internal Cooling of the Piston Rod in Non-Lubricated Piston Compressors [PDF]

open access: yes, 2012
In non-lubricated piston compressors the wear of the piston rod packing rings is still a problem that needs to be considered. Due to the demands of high gas pressure and leak-tight sealing the frictional heat of the rings is causing high temperatures in ...
