Bilateral SERS‐Microneedle Patch for Co‐Diagnosis of Diabetes Mellitus and Tuberculosis Comorbidity
Advanced Science, EarlyView.Our study introduced a U@mP@Au‐mediated bilateral SERS‐microneedle patch for analyzing glucose levels from ISF and sensitively detecting TB biomarkers from sputum, respectively. This integrated dual‐analyte detecting platform can be used for co‐diagnosis of diabetes mellitus (DM) and tuberculosis (TB) comorbidity, which was demonstrated in ex vivo ...

COMPLEX SIMULATION MODEL OF TRAIN BREAKING-UP PROCESS AT THE HUMPS
Nauka ta progres transportu, 2015 Purpose. One of the priorities of station sorting complex functioning improvement is the breaking-up process energy consumptions reduction, namely: fuel consumption for train pushing and electric energy consumption for cut braking.

Temporary speed hump impact evaluation
, 2020 The main objective of this research was to evaluate the impact of temporary speed humps and speed tables on vehicle speeds, vehicle speed profiles, and traffic volumes along local and/or collector streets in several rural Iowa cities. A 25 mile per hour (mph) temporary speed hump and a 30 mph temporary speed table, both made of recycled rubber, were ...

Hair Follicle Seedling Cryomicroneedles from Hierarchical Microfluidic Organoid on a Chip
Advanced 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.

Advanced 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 ...

The influence of random factors on the estimation of the speed and time of rolling cuts from sorting humps [PDF]
MATEC Web of ConferencesThe main direction of increasing efficiency and safety of the work of sorting humps is the management automation of breaking-up of trains. The difficulty of solving this problem is due to the fact that it is solved in the absence of accurate information ...

Advanced 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 ...

Advanced 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.
