Low‐Cost WS2 Photodetector on Water‐Soluble Paper for Transient Electronics

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a transient WS2 photodetector fabricated on water‐soluble paper using simple mechanical abrasion and pencil drawing. The device demonstrates reliable photoresponse and mechanical flexibility. It dissolves in water within seconds after use, enabling material recovery and reuse.

The US space station and its electric power system [PDF]

open access: yes
The United States has embarked on a major development program to have a space station operating in low earth orbit by the mid-1990s. This endeavor draws on the talents of NASA and most of the aerospace firms in the U.S. Plans are being pursued to include

Mimicking Synaptic Plasticity: Optoionic MoS2 Memory Powered by Biopolymer Hydrogels as a Dynamic Cations Reservoir

open access: yesAdvanced Functional Materials, EarlyView.
Janus (MoS2) transistors functionalized with sodium alginate (SA) and poly(vinylidene fluoride‐co‐trifluoroethylene) [P(VDF‐TrFE)] exhibit persistent photo‐induced ionic gating, driven by dynamic cation migration at the hybrid interface. This ionic mechanism enables finely tunable photoconductivity and emulates key synaptic plasticity behaviors ...

Modelling the energy efficiency of microcell base stations [PDF]

open access: yes, 2011
The power consumption of wireless access networks will become a major issue in the coming years. Therefore, it is important to have a realistic idea about the power consumption of each element in those access networks. In this paper, an energy efficiency

Electrically Binary and Ternary Convertible CMOS Inverter and Logic Gate Using Complementary Field‐Effect Transistors Based on Vertically Stacked MoS2/WSe2 n‐/p‐ Field‐Effect Transistors

open access: yesAdvanced Functional Materials, EarlyView.
In this work, a reconfigurable T‐CMOS inverter based on vertically stacked MoS2 and WSe2 MOSFETs with a gate‐tunable MoS2 resistor, enabling stable ternary logic, is demonstrated. The T‐CMOS inverter supports electrical switching between ternary and binary modes and is further extended to implement ternary NAND (NMIN) and NOR (NMAX) logic gates ...

A New Deep Learning Methodology for Alarm Supervision in Marine Power Stations

open access: yesSensors
Marine engineering officers operate and maintain the ship’s machinery during normal navigation. Most accidents on board are related to human factors which, at the same time, are associated with the workload of the crew members and the working environment.
