Exploring the potential of end-capping acceptor engineering on indolo[3,2-]indole-based small molecules for efficient organic and perovskite solar cells.

Photovoltaic (PV) materials, especially organic and perovskite solar cells are effective candidates for meeting the rising global energy demand. Herein, we have designed indolo[3,2-]indole-based six molecules (IDF1-IDF6) as hole-transporting materials (HTMs) for perovskite solar cells (PSCs) and donor materials for organic solar cells (OSCs). The results demonstrated that IDF1-IDF6 molecules have tight π-π stacking, more negative HOMO levels (-5.

Designing of fluorine-substituted benzodithiophene-based small molecules with efficient photovoltaic parameters.

In this study, four hole-transporting materials (JY-M1, JY-M2, JY-M3, and JY-M4) are designed by modifying benzothiadiazole-based core with diphenylamine-based carbazole via acceptors through thiophene linkers. The designed molecules exhibited deeper HOMO energy with smaller energy gaps than the reference JY molecule which enhance their hole mobility. The absorption spectra of the JY-M1, JY-M2, JY-M3, and JY-M4 molecules are located at 380 nm to 407 nm in the gaseous phase and 397 nm to 433 nm in the solvent phase, which is red-shifted and higher than the reference molecule, demonstrating that designed molecules possess improved light absorption properties and enhanced effective hole transfer.

Mental and physical health correlates of the psychological impact of the first wave of COVID-19 among general population of Pakistan.

The primary aim was to assess the role of mental and physical health of COVID-19 and its psychological impact in the general population of Pakistan during the first wave of COVID-19. It was hypothesized that there would be a significant predictive association among socio-demographic variables, psychological impact and mental health status resulting from COVID-19, and poor self-reported physical health would be significantly associated with adverse psychological impact and poor mental health status because of COVID-19. A cross-sectional survey research design was used in which 1,361 respondents were sampled online during lockdown imposed in the country.

Application of Fe-RGO for the removal of dyes by catalytic ozonation process.

Due to continuous industrialization, the discharge of hazardous dyes has enormously disrupted the ecosystem causing environmental problems. Due to the stable recalcitrant nature of dyes, advanced catalytic ozonation processes with the latest catalyst are under investigation. Fe-RGO is an effective oxidation catalyst, and the metal loaded platform provides enhanced catalytic performance.

Reno Protective Role Of N Acetyl Cysteine And Aqueous Extract Of Berberis Lycium Royale Root Bark On Rats.

Background: N acetyl cysteine and Berberis lycium Royale root bark have been used to treat kidney diseases. Objectives of the study were to evaluate the individual and combined effect of N acetyl cysteine and aqueous extract of Berberis lycium Royale root bark in Gentamicin induced nephrotoxicity in rats. This randomized control trial conducted at Islamic International Medical College, Rawalpindi in collaboration with NIH, Islamabad in 1 month from Sep to Oct 2020.

Emotional response bias, autistic traits and paranormal beliefs in patients with Obsessive Compulsive Disorder.

Objective: To find the relationship involving autistic traits, paranormal beliefs and emotional response bias in obsessive compulsive disorder patients.

Method: The cross-sectional quasi-experimental study was conducted from November 2017 to November 2018 at the Government College University, Lahore, Pakistan, and comprised patients with obsessive compulsive disorder and healthy controls from the general population aged 20-40 years. Data was collected using the self-reporting Autism Spectrum Quotient, the Revised Paranormal Belief Scale, the Emotional Recognition Task and the Obsessive Compulsive Disorder symptom checklist.

A randomized controlled trial of a forgiveness intervention program with female acid attack survivors in Pakistan.

Despite the traumatic effects of acid violence on its victims, treatment options are very limited. The present study was aimed at examining the efficacy of a forgiveness intervention with female survivors of acid attack violence in Pakistan. Female acid attack victims in Pakistan were randomized to either a forgiveness group (n = 8) or a treatment-as-usual (TAU; n = 8) control group.

Subtractive Proteome Mining Approach towards Unique Putative Drug Targets Identification for Salmonella typhimurium.

Background: Salmonella typhimurium is a rod-shaped bacteria with a Gram-negative genus, belonging to the Enterobacteriaceae family of microbes, which invades the intestinal lumen of Human. Salmonella typhimurium is a root source, accounting for gastroenteritis in humans as well as in other mammals. Gastroenteritisis associated with Salmonella Typhimurium interacts with the contaminated food and water and spreads to nearby people in the area.
