Hair Follicle Seedling Cryomicroneedles from Hierarchical Microfluidic Organoid on a Chip

open access: yesAdvanced Science, EarlyView.
In this paper, a hierarchical microfluidic chip is developed to produce uniform hair follicle organoids (HFOs) in cryomicroneedles. Cryopreservation agents encapsulate HFOs, preserving viability and hair growth potential. The cryomicroneedles enable simple intradermal transplantation with good skin penetration.

Rail skates for fixing rolling stock on the station tracks. Ground tests

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2016
Currently manual brake shoes on Russian railways are used to solve two main tasks: to adjust uncoupling speed at humps (hump shoes), and to fix the rolling stock on the railway tracks.

A review of literature on the effects of road hump on traffic speed and traffic noise in institutional area [PDF]

open access: yes, 2018
Traffic speed and noise are the major transport-related determinants in affecting the quality of learning and research environment in a University. The calm and safe environmental set-up of a University is very crucial in creating a conducive learning ...

Supercritical CO2‐Induced Porous MXene Films for Electromagnetic Interference Shielding and Infrared Stealth

open access: yesAdvanced Science, EarlyView.
The phase transition of supercritical CO2 induces the foaming of dense MXene film without compromise inherent structure of MXene nanosheet. The foamed porous MXene film manifests remarkable EMI shielding and infrared thermal camouflage performances. Moreover, the foaming strategy is broadly adaptable and can be extended to other two‐dimensional films ...

Stability and Control of Car Dynamics with a Quarter Model via a Novel Simple Harmonic Hump under External Force

open access: yesMathematics
Effects of the road, such as speed bumps, can significantly affect a car’s stability. This study focuses on how a quarter-car model is affected by a basic harmonic speed hump and how Cubic Negative Velocity Control (CNVC) is used to control the amplitude

Atomic‐Level CuOx‐CoOx‐Pd Interfacial Engineering Enables Hierarchical Synergy for High‐Efficiency ORR Pathways and Boosted Power Output in Alkaline Fuel Cells

open access: yesAdvanced Science, EarlyView.
Atomically dispersed CuOx (CPCu‐1) forms isolated Cu–Ov sites that enable defect‐mediated O2 activation and fast electron/proton transfer via interfacial synergy. In contrast, thick CuOx clusters (CPCu‐10) promote a surface‐adsorption‐controlled pathway with intermediate accumulation, highlighting a mechanism switch from interfacial activation to ...

Programmable Multi‐Axially Aligned Aerogels via Sequential Freeze‐Casting for Tailored Anisotropy and Tunable Mechanics

open access: yesAdvanced Science, EarlyView.
Conventional single‐gradient freeze‐casting typically produces unidirectional porous architectures with limited transverse connectivity. The Sequential Hybridization by Infiltration and Freeze‐casting Technique (SHIFT) addresses this constraint by integrating secondary aligned structures within a preformed primary scaffold.

PENGARUH PENGGUNAAN SPEED HUMPS TERHADAP TINGKAT KEBISINGAN

open access: yes, 2014
Speed humps are speed limiting devices to protect pedestrians and reduce the accident rate. The installation of speed humps in residential can reduce the speed of motorists but, at the same time, also can create a problem. The purpose of this study is to

From Cytoskeletal Remodeling to Oocyte Quality: The Emerging Role of Mechanics

open access: yesAdvanced Science, EarlyView.
Mechanical properties of the oocyte are increasingly recognized as critical determinants of meiotic success and developmental potential. How actomyosin remodeling controls oocyte mechanics, how these properties are altered in pathological conditions, and how they could serve as markers in reproductive medicine are examined.
