Rapid and Direct Detection of Methamphetamine in Biofluids using a MXene‐Enabled Electrochemical Sensor

open access: yesAdvanced Science, EarlyView.
A MXene‐enhanced electrochemical sensor enables the rapid and direct detection of methamphetamine. Molecular simulations reveal that specific MXene surface functional groups act as key signal amplifiers by facilitating interfacial interactions. The sensor demonstrates high sensitivity and robust performance in complex biological matrices.

Modulating Persistent Photoconductivity through Barrier Engineering for High‐performance and Multifunctional Two‐dimensional Optoelectronic Devices

open access: yesAdvanced Science, EarlyView.
Schottky barrier engineering using van der Waals contacts enables effective modulation of persistent photoconductivity (PPC) in optoelectronic devices. A high persistent photoconductivity gain (PPCG) (307.6%) is achieved in a high‐barrier Au/MoS2 junction, supporting photomemory and optoelectronic synaptic behaviors. A low PPCG (4.72%) is achieved in a

Computational Arithmetic Geometry

open access: yesJournal of Computer and System Sciences, 2001
We consider the average-case complexity of some otherwise undecidable or open Diophantine problems. More precisely, consider the following: I.Given a polynomial f?Zv, x, y, decide the sentence ?v?x?yf(v, x, y)=?0, with all three quantifiers ranging over N (or Z). II.Given polynomials f1, ?, fm?Zx1, ?, xn with m?n, decide if there is a rational solution

Insights Into CO2 Loss, pH Effects, and Tafel Kinetics in Ni Single Atom‐Driven Bicarbonate Electroreduction

open access: yesAdvanced Science, EarlyView.
Selective CO formation in bicarbonate electrolysis is achieved by retaining reactive CO2 and tuning pH, while the competing hydrogen evolution reaction occurs at the interface. The rate‐determining step couples the chemical equilibrium of bicarbonate/CO2 with electrochemical charge transfer, offering insight into optimizing reaction conditions for ...

Arithmetic using COMPUTE [PDF]

open access: yes, 1991
Data items which are going to be used in arithmetic must be stored in numeric fields. The fields declared in the Data Division must also be large enough to hold the numbers being used — be particularly careful about the length of the field that will hold the answer.

Precise Tailoring 3D Printed In Situ Toughening Low‐k Microwave Transparent Structure via Thiol‐acrylate Chain Transfer Behavior

open access: yesAdvanced Science, EarlyView.
An in situ thiol–acrylate chain transfer‐mediated toughening strategy is introduced for Digital Light Processing (DLP) printing. Benefiting from its excellent printability, a printed gyroid lattice‐filled plate (100 µm wall thickness) achieves 92% transmittance at 10 GHz under a 50° incidence angle following structural optimization. ABSTRACT The unique

A computer-assisted proof for solutions of Elkouh’s equation related to Navier–Stokes equations

open access: yesFixed Point Theory and Algorithms for Sciences and Engineering
The present paper presents a computer-assisted proof of the existence of solutions for Elkouh’s equation, which is representative of fluid flow between parallel circular disks. The proposed approach is based on an infinite-dimensional fixed-point theorem
