Modelling and design of a coupled system of multiple hydraulic systems and large structures

open access: yesNihon Kikai Gakkai ronbunshu
Control of large structures often involves the use of hydraulic equipment due to the large power requirements. In this study, a large telescope is taken as an example of a large structure.

Noise Rectification and Fluctuations of an Asymmetric Inelastic Piston

open access: yes, 2008
We consider a massive inelastic piston, whose opposite faces have different coefficients of restitution, moving under the action of an infinitely dilute gas of hard disks maintained at a fixed temperature.

Harnessing Next‐Generation 3D Cancer Models to Elucidate Tumor‐Microbiome Crosstalk

open access: yesAdvanced Healthcare Materials, EarlyView.
Centralizes the microbiome within 3D tumor‐microbiome model platforms, including spheroids, organoids, 3D‐bioprinted constructs, and microfluidic chips, each enabling structured host‐tumor‐microbe studies. These systems support bacterial colonization, facilitating investigation of microbial impacts on tumor growth, immunity, and therapy. The microbiome

Affordable Biogenic Anti‐Icing Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
The article explores affordable biogenic coatings that prevent icing by combining coconut shell charcoal with natural hydrophobic agents such as beeswax. It shows how particle size and surface treatment influence water repellence, heat absorption, and self‐cleaning ability.

Influence of hydraulic brakes typical parameters on the process of recoiling mass breaking

open access: yesVojnotehnički Glasnik, 1998
The mathematical model for providing typical parameters of the process of breaking of recoiling mass on an artillery gun is presented. The model of hydraulic brakes with some discrete distribution of orifice surfaces in the cylinder is defined.

Using a Zero‐Strain Reference Electrode to Distinguish Anode and Cathode Volume Changes in a Solid‐State Battery

open access: yesAdvanced Materials Interfaces, EarlyView.
Volume changes of a solid‐state battery cell are separated into the individual contributions of anode and cathode. Simultaneously determining the “reaction volumes” of both electrodes requires a reference electrode with a pressure‐independent potential.

Solar engine [PDF]

open access: yes, 1982
A solar engine is disclosed in which a fluid, which is first heated and then cooled, forces a piston outward as the fluid is heated, and then draws the piston inward as the fluid is cooled. The piston is connected to a shaft and produces work as it moves
