Biobased Bionic Spider Silk via Electrostatic Complexation for Simultaneously Harvesting Atmospheric Water and Triboelectric Energy

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐based bionic spider silk and spider web are first prepared using polyelectrolyte complexation technique for the simultaneous harvesting of water and triboelectric energy. The advantage of this process lies on entirely bio‐based materials, fully green water‐processable procedures, extremely high production rate (99.36%), excellent fog harvesting ...

Acoustic Assessment of the Micronekton Community on the Chatham Rise, New Zealand, Using a Semi-Automated Approach

open access: yesFrontiers in Marine Science, 2019
Micronekton are a key component of the pelagic food web of the Chatham Rise east of New Zealand. The Chatham Rise is an important fishing area for hoki (Macruronus novaezelandiae), New Zealand’s largest finfish fishery, and a predator on mesopelagic fish.

Random Sequential Generation of Intervals for the Cascade Model of Food Webs [PDF]

open access: yes, 2011
The cascade model generates a food web at random. In it the species are labeled from 0 to $m$, and arcs are given at random between pairs of the species.

Novel Functional Materials via 3D Printing by Vat Photopolymerization

open access: yesAdvanced Functional Materials, EarlyView.
This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Mountains in the Sea: Food Web Mystery [PDF]

open access: yes
In this activity, students will focus on some unique aspects of food webs in the vicinity of seamounts. They will be able to describe typical marine food webs, and explain why food is generally scarce in the deep-ocean environment. They will then discuss

Evaluation of climate change scenarios based on aquatic food web modelling [PDF]

open access: yes, 2008
In the years 2004 and 2005 we collected samples of phytoplankton, zooplankton and macroinvertebrates in an artificial small pond in Budapest. We set up a simulation model predicting the abundance of the cyclopoids, Eudiaptomus zachariasi and Ischnura ...

A Quantitative Printability Framework for Programmable Assembly of Pre‐Vascular Patterns via Laser‐Induced Forward Transfer

open access: yesAdvanced Healthcare Materials, EarlyView.
Laser‐Induced Forward Transfer (LIFT) is presented as a powerful micropatterning tool. An objective printability framework is developed to assess optimal printing parameter combinations. The technology is further explored for its ability to deterministically deposit microdroplets at predefined locations following CAD designs, enabling the patterning of

Are type 3 functional responses just statistical apparitions?

open access: yesEcosphere
Type 3 (sigmoidal) functional responses can protect rare prey from predation, but such functional responses are not often described. It is also not clear that factors that are hypothesized to promote type 3 functional responses, such as predator–prey ...

An illustration of web survey methododlogy [PDF]

open access: yes, 2009
A former study in the Danish primary schools has shown that there is an association between organic school food policies and indicators (proxies) for healthy eating among children when (school food coordinators) statements on indicators (proxies) for ...
