Emerging transition metal and carbon nanomaterial hybrids as electrocatalysts for water splitting: a brief review.

Electrocatalytic water splitting has appeared to be a sustainable green technology for hydrogen and oxygen production, and noble metal-based electrocatalysts, like Pt for hydrogen evolution reaction (HER) and RuO/IrO for oxygen evolution reaction (OER) have been proved to be state-of-the-art in water electrolyzers. However, high cost and scarcity of noble metals hinder large-scale applications of these electrocatalysts in practical commercial water electrolyzers. As an alternative, transition metal based electrocatalysts have attracted great attention because of the exciting catalytic performance, cost-effectiveness and abundant availability.

Contaminants from a former Croatian coal sludge dictate the structure of microbiota in the estuarine (Raša Bay) sediment and soil.

Introduction: Croatian superhigh-organic-sulfur Raša coal had been mined for nearly 400 years. The release of hazardous trace elements (HTEs) and toxic organic pollutants (TOPs) into the local environment by coal mining, preparation, and combustion activities has resulted in pollution.

Methods: In this study, the diversity and composition of microbial communities in estuarine sediment and soil samples as well as community function responses to the pollutants were investigated.

Comparison of effectiveness of muscle energy technique with Mulligan mobilization in patients with non-specific neck pain.

Objective: To compare the efficacy of muscle energy technique with Mulligan mobilisation in patients having non-specific neck pain.

Methods: The quasi-experimental study was conducted at the Physiotherapy Department of Mayo Hospital, Lahore, Pakistan, from March to September 2017, and comprised patients of either gender having non-specific neck pain who ere divided into two groups. In group 1 patients, muscle energy technique was used, while group 2 patients had Mulligan mobilisation.

High temperature proton exchange membrane fuel cells: progress in advanced materials and key technologies.

High temperature proton exchange membrane fuel cells (HT-PEMFCs) are one type of promising energy device with the advantages of fast reaction kinetics (high energy efficiency), high tolerance to fuel/air impurities, simple plate design, and better heat and water management. They have been expected to be the next generation of PEMFCs specifically for application in hydrogen-fueled automobile vehicles and combined heat and power (CHP) systems. However, their high-cost and low durability interposed by the insufficient performance of key materials such as electrocatalysts and membranes at high temperature operation are still the challenges hindering the technology's practical applications.

Comparison of conservative exercise therapy with and without Maitland Thoracic Manipulative therapy in patients with subacromial pain: Clinical trial.

Objective: To determine the effect of conservative exercise therapy with and without Maitland thoracic manipulation in patients with subacromial pain.

Methods: The randomised controlled trial study was conducted at the Mayo Hospital, Lahore, Pakistan, from June 2015 to February 2016, and comprised patients with subacromial pain (group 1) and controls (group 2).Pre-assessment was done by using numeric pain rating scale and shoulder pain and disability index as subjective measurements, while range of motion was taken as objective measurement.

Teaching paediatric critical care medicine to paediatric residents.

Critical care training during paediatric residency provides an ideal opportunity to learn and refine the skills needed in the early recognition and prompt treatment of the acutely ill paediatric patients. Paediatric critical care medicine is a relatively young sub-specialty in Pakistan. The aim of this study is to describe our experience of teaching paediatric residents in paediatric critical care medicine during paediatric intensive care unit rotation.
