Development of a library information management system

open access: yesИзвестия Томского политехнического университета: Промышленная кибернетика
Under limited resources, developing a Library Information System presents a pertinent challenge for many educational institutions and libraries. This article describes the implementation of a project to create a functional and efficient system capable of

Lone‐Pair‐Induced Lattice Distortion in Lead‐Free Hybrid Perovskites for High‐Performance Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
A lead‐free tin‐based hybrid perovskite is designed in which stereochemically active lone‐pair electrons on tin distort the crystal lattice and break its symmetry. Blended into a flexible polymer, the material converts pressure into electricity at milliwatt‐scale power density and continues working far below freezing, powering a commercial wristwatch ...

Research on Construction of Test Environment for Assessment of RF-Induced Heating Effects of Implants

open access: yesZhongguo yiliao qixie zazhi
In magnetic resonance examination, the interaction between implants and the radio frequency (RF) fields induces heating in human tissue and may cause tissue damage.

Role of Structural Disorder on Phonon Transport and Thermal Conductivity in Li6PS5Br

open access: yesAdvanced Functional Materials, EarlyView.
Solid electrolytes are fast ion and slow heat conductors. Although both transport properties are governed by lattice dynamics and atomic structure, their interplay remains poorly understood. Here, we study this interrelation in anion‐ordered and disordered Li6PS5Br.

A Case Study on the Reuse of Digital Archaeological Data: An Analysis of the Atlas of Hillforts of Britain and Ireland

open access: yesJournal of Computer Applications in Archaeology
The Atlas of Hillforts of Britain and Ireland is a large open dataset published online for reuse and reinterpretation. This data is large and complex, making it challenging to manipulate, especially in a discipline where a lack of data literacy skills is

The Effect of Hydrophilic Headgroup Chemistry on Peptoid‐Directed Mineralization of CaCO3

open access: yesAdvanced Functional Materials, EarlyView.
Amphiphilic peptoids alter the pathway and outcome of calcium carbonate crystallization, which progresses through amorphous calcium carbonate (ACC) to vaterite to calcite rhombs in the absence of peptoids. In contrast, amine‐terminated peptoids produce vaterite disks and carboxyl‐terminated peptoids produce calcite mesocrystals.

Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells

open access: yesAdvanced Functional Materials, EarlyView.
In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

Pyphant - A Python Framework for Modelling Reusable Information Processing Tasks [PDF]

open access: yes, 2008
We are presenting the Python framework Pyphant for the creation and application of information flow models. The central idea of this approach is to encapsulate each data processing step in one unit which we call a worker.

Dynamic Observation of Lacy Pattern Formation in a Bone Tissue Model Using Liquid Phase Scanning Transmission Electron Microscopy

open access: yesAdvanced Functional Materials, EarlyView.
Here, we establish a low‐dose liquid‐phase electron microscopy workflow for real‐time observation of biological processes in hydrated conditions. Beam damage is reduced by imaging only 20% of the pixels and reconstructing the complete image using an inpainting algorithm.
