Bright fibrils in Ca II K [PDF]

open access: yes, 2009
Context: Except for the Ca II resonance lines, fibrils are ubiquitously present in most high-resolution observations of chromospheric lines. Aims: We show that fibrils are also a prevailing feature in Ca II K, provided the spatial-resolution is sufficiently high.

Advanced Nano‐Fibrillated Cellulose/Modified MXene Janus Membrane for Continuous 24‐h Water‐Power Co‐Generation

open access: yesAdvanced Functional Materials, EarlyView.
The Janus membrane integrates a superhydrophilic CNF@CTAB‐MXene layer with a superhydrophobic PTFE layer, enabling efficient solar‐driven water evaporation and electricity generation. It achieves an evaporation rate of 1.51 kg m−2 h−1 with excellent salt resistance and long‐term stability.

Native Lignin Migration and Clustering in Wood: Superhydrophobic, Antimold, and Tribonegative Layers for Rain‐Driven Electrification

open access: yesAdvanced Functional Materials, EarlyView.
This study proposes a sustainable solution for rainwater‐driven energy harvesting by harnessing the intrinsic properties of lignin in wood. The first demonstration of an all‐wood tribonegative material for liquid–solid triboelectric nanogenerators is presented, eliminating the need for fluorine‐containing polymers and functional additives.

Selective parenchymal clamping in open partial nephrectomy: Early experience with a low cost, reusable novel parenchymal clamp

open access: yesBJUI Compass, Volume 4, Issue 1, Page 88-95, January 2023., 2023
Abstract Objectives The objective of this study is to present our initial experience with a novel parenchymal clamp (NPC) developed to allow partial nephrectomies (PN) to be performed without whole kidney ischaemia. We compare patients who underwent PN with the NPC with those undergoing standard PNs. Methods The NPC applies pressure only to the portion

Epidemiology of Atrial Fibrillation in the 21st Century

open access: yesCirculation Research, 2020
Supplemental Digital Content is available in the text. Accompanying the aging of populations worldwide, and increased survival with chronic diseases, the incidence and prevalence of atrial fibrillation (AF) are rising, justifying the term global epidemic.

Age‐Dependent Predictive Value of Endothelial Dysfunction for Arrhythmia Recurrence Following Pulmonary Vein Isolation

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
Background The mechanisms of atrial fibrillation (AF) are highly divergent. The prevalence of AF increases significantly with age, and underling mechanisms might vary with age.

NACore Amyloid Formation in the Presence of Phospholipids

open access: yesFrontiers in Physiology, 2020
Amyloids are implicated in many diseases, and disruption of lipid membrane structures is considered as one possible mechanism of pathology. In this paper we investigate interactions between an aggregating peptide and phospholipid membranes, focusing on ...
