Higher-dimensional black holes: Braneworld stars and Hawking radiation. [PDF]
, 2007 In this thesis two aspects of braneworld models are studied. A new attempt at finding the metric of a braneworld black hole within the second Randall-Sundrum model is explored. Branes containing distributions of perfect fluid are embedded in a variety of

An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots
Advanced Functional Materials, EarlyView.This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.

Geodesic Geometry of Black Holes [PDF]
, 2006 The study of geodesics is of intrinsic significance in the study of the geometry of space-time. In this thesis null, space-like and time-like geodesics are studied in the case of the space-times of Schwarzschild, Reissner-Nordstrouml;m and Kerr black ...

Advanced Functional Materials, EarlyView.A fully polymeric two‐dimensional array of Dielectric Elastomers enables self‐sensing, cooperative actuation, and large‐stroke operation in a DE‐based autonomous conveyor. Based only on voltage and current measurements at actuator level, the system detects the presence of a ball and subsequently drives it toward a target position.

Perpetual exploration in anonymous synchronous networks with a Byzantine black hole
CoRRIn this paper, we investigate: ``How can a group of initially co-located mobile agents perpetually explore an unknown graph, when one stationary node occasionally behaves maliciously, under an adversary's control?'' We call this node a ``Byzantine black hole (BBH)'' and at any given round it may choose to destroy all visiting agents, or none.

Network Topology Governs Photocatalytic Water Splitting in Organic Two‐Dimensional Crystals
Advanced Functional Materials, EarlyView.Network topology in organic two‐dimensional crystals (O2DCs) dictates the photocatalytic water splitting performance. Kagome‐lattice O2DCs exhibit strong electron‐hole mass asymmetry, spatially separated carriers, and longer recombination lifetimes, exceeding rhombic isomers.

Advanced Functional Materials, EarlyView.A hybrid PEDOT/Fc‐LPEI conducting/redox polymer bioanode synergistically improves microbial extracellular electron transfer (EET) in Shewanella oneidensis MR‐1. The dual‐layer interface delivers 18‐fold higher current output and 27‐fold greater charge collected than bare carbon felt, highlighting an effective strategy for high‐performance ...

Multi‐Level Saturation Current Encoding in Two‐Dimensional Ferroelectric Source‐Gated Transistors
Advanced Functional Materials, EarlyView.A 2D ferroelectric source‐gated transistor (SGT) operates with a non‐volatile, multi‐level saturation current controlled by ferroelectric polarization. Operando electrostatic and photocurrent imaging link the current limitation to source‐side depletion, identifying saturation current as a programmable, read‐bias‐tolerant device parameter toward low ...
