Tunable Focusing Liquid Crystal Lenses: The Challenges and the Opportunities.

The utilization of liquid crystals (LC) as materials has enabled the enlargement of lenses with the potential to alter their focus. Tunable LC lenses with adjustable focus are essential for optical imaging, sensing, and detection devices. This technology offers many benefits, such as the ability to adjust focus, operate with low power, and be easily made.

Musculoskeletal Computed Tomography: How to Add Value When Reporting Adult Lower Limb Trauma.

Computed tomography plays an ever-increasing role in the management of fractures and dislocations due to its capability in efficiently providing multiplanar reformats and 3-dimensional volume rendered images. It can reveal findings that are occult on plain radiography and therefore allow for more accurate decision making with regard to fracture classification and management. Clinical radiologists play a critical role in facilitating the processing of imaging to provide adequate image reformats in the desired planes, producing 3 dimensional images but most crucially identifying pertinent findings, which will contribute between the selection of nonoperative and operative management and potentially influence surgical technique.

Polypyrrole functionalized MoS for sensitive and simultaneous determination of heavy metal ions in water.

Assessing heavy metal ion (HMI) contamination to sustain drinking water hygiene is a challenge. Conventional approaches are appealing for the detection of HMIs but electrochemical approaches can resolve the limitations of these approaches, such as tedious sample preparation, high cost, time consuming and the need for trained professionals. Here, an electrochemical approach is developed using a nano-sphered polypyrrole (PPy) functionalized with MoS (PPy/MoS) by square wave anodic stripping voltammetry for the detection of HMIs.

The "Mr. and Mrs. Ghat crab", Ghatiana dvirupa sp. nov. (Decapoda: Brachyura: Gecarcinucidae) from the Central Western Ghats of India.

A new species of gecarcinucid freshwater crab, Ghatiana dvirupa sp. nov., is described herein from the Kali Tiger Reserve of the Uttara Kannada district, Karnataka state, India.

Zinc oxide/tin oxide nanoflower-based asymmetric supercapacitors for enhanced energy storage devices.

Research on energy storage devices has focused on improving asymmetric supercapacitors (ASCs) by utilizing two different electrode materials. In this work, we have successfully prepared a unique material, ZnO/SnO nanoflower, the hydrothermal method. Graphene oxide (GO) was synthesized by applying the modified Hummers' technique.
