Efficient Hydroxyl Diffusion Triggers Surface Hydronium Enrichment and Bulk Proton Participation to Boost Alkaline Hydrogen‐Evolving Reaction

open access: yesAdvanced Materials, EarlyView.
For the first time, we shed light on the surface‐to‐bulk diffusion, induction, and reaction behaviors of OH−, H+, and H2O species on model oxides for alkaline hydrogen‐evolving reaction (HER). We first demonstrate that bulk OH− diffusion significantly affects the generation of proton sources and the diffusion/reaction behaviors of protons, thus ...

On Queues with Working Vacation and Interdependence in Arrival and Service Processes

open access: yesMathematics, 2023
In this paper, we consider two queuing models. Model 1 considers a single-server working vacation queuing system with interdependent arrival and service processes.

In Situ Lithium Nitridosilicate Interlayer via Reactive Anolyte Design for All‐Solid‐State Silicon Anodes

open access: yesAdvanced Materials, EarlyView.
Interfacial reactions in all‐solid‐state batteries are conventionally suppressed; here, they are designed. Vacancy‐rich β‐Li3N, acting as an anolyte, reacts controllably with silicon during composite anode fabrication, building a purpose‐made lithium nitridosilicate interlayer on every particle surface.

Study of Bulk Arrival with Working Vacation [PDF]

open access: yes, 2018
Here arrivals of the customer follow poisson distribution and there is single server who is providing service to the customer. Also server serve the customer on first come first serve basis.

Analysis of an M/M/1 Queue With Working Vacation and Vacation Interruption [PDF]

open access: yes, 2019
In this paper, an M/M/1 queue with working vacation and vacation interruption is investigated. The server is supposed to interrupt the vacation and return back to the normal working period, if there are at least N customers waiting in the system at a ...

Vacation Policy for k-out-of-n Redundant System with Reboot Delay [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences
Redundancy is a well-known concept for system resilience; k-out-of-n redundancy stipulates that a minimum number of functional components must be present for the system to function.

Equilibrium and Optimal Strategies in M/M/1 Queues with Working Vacations and Vacation Interruptions [PDF]

open access: yesMathematical Problems in Engineering, 2016
We consider the customers equilibrium and socially optimal joining-balking behavior in single-server Markovian queues with multiple working vacations and vacation interruptions. Arriving customers decide whether to join the system or balk, based on a linear reward-cost structure that incorporates their desire for service, as well as their unwillingness

Controlled Synthesis of Tri‐ and Multi‐Doped Graphene

open access: yesAdvanced Materials Interfaces, EarlyView.
This review systematically evaluates synthesis routes for tri‐ and multi‐doped graphene, from hydrothermal and pyrolysis methods to flash Joule heating, critically assessing how each governs dopant incorporation, bonding configuration, and resulting electronic properties.

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

open access: yesAdvanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...
