Van Der Waals Hybrid Integration of 2D Semimetals for Broadband Photodetection

open access: yesAdvanced Materials, EarlyView.
Advanced broadband photodetector technologies are essential for military and civilian applications. 2D semimetals, with their gapless band structures, high mobility, and topological protection, offer great promise for broadband PDs. This study reviews the latest advancements in broadband PDs utilizing heterostructures that combine 2D semimetals with ...

Inorganic Dielectric Materials Coupling Micro‐/Nanoarchitectures for State‐of‐the‐Art Biomechanical‐to‐Electrical Energy Conversion Devices

open access: yesAdvanced Materials, EarlyView.
Biomechanical‐to‐electrical energy conversion devices are uniquely suited for self‐driven physiological information monitoring and powering human–computer interaction systems. These devices based on micro‐/nanoarchitectured inorganic dielectric materials (MNIDMs) have shown ultrahigh electromechanical performance and thus great potential for practical ...

Cobordism Theory and Poincare Conjecture [PDF]

open access: yesarXiv, 2009
In this paper, by use of techniques associated to cobordism theory and Morse theory,we give a simple proof of Poincare conjecture, i.e. Every compact smooth simply connected 3-manifold is homeomorphic to 3-sphere.

A Natural Lignification Inspired Super‐Hard Wood‐Based Composites with Extreme Resilience

open access: yesAdvanced Materials, EarlyView.
Super‐hard wood‐based composites (WBC) are designed and developed inspired by the mesoscale homogeneous lignification process intrinsic to tree growth. This innovative hybrid structure is achieved by leveraging the infusion of low‐molecular‐weight phenol formaldehyde resin into the cell walls of thin wood slices, followed by a unique multi‐layer ...

Effects of stocking density on the performance of lettuce (Lactuca sativa) in small‐scale lettuce‐Nile tilapia (Oreochromis niloticus L.) aquaponic system

open access: yesAquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 458-469, December 2022., 2022
Graphical Abstract : Aquaponics, hydroponics, stocking density. Abstract Aquaponics incorporates aquaculture with hydroponics, whose principles and operations largely remain untested. Currently, there is a knowledge gap on the performance of aquaponic systems used for fish production under different stocking densities.
