Exploring the correlations between social support, resilience, well-being, and mental health variables among youth in border areas of Jammu and Kashmir.

Background: The border areas of Jammu and Kashmir have long been affected by conflict, potentially impacting the mental health of youth. Understanding the relationships between social health factors and mental health outcomes in these regions is crucial for developing effective interventions.

Aim: This study aims to investigate the correlations between social health factors (social support, resilience, and well-being) and mental health outcomes (stress, anxiety, and depression) among youth living in the border areas of Jammu and Kashmir.

Perceived stress, anxiety and depression : Living along the border in Jammu and Kashmir.

Background: Conflicts adversely affect psychological well-being and are associated with mental disorders.

Aim: The study aims to assess the levels of perceived stress, anxiety and depression and their association with demographic factors among the youth in the border villages of Jammu and Kashmir (J&K).

Methods: A cross-sectional study was conducted among youth aged 18 to 25 years.

Association of vitamin B12 mediated hyperhomocysteinemia with depression and anxiety disorder: A cross-sectional study among Bhil indigenous population of India.

Background: Indigenous populations in India are amongst the poorest and most marginalized population groups experiencing severe health deprivation.

Aim: The present study is the first study that aims to understand the association of micronutrient deficiencies (vitamin B12 and folate) and MTHFR C677T gene polymorphism with depression and generalized anxiety disorder (GAD) among the Bhil indigenous population of India.

Methods: A total of 303 participants aged 25-65 years of both sexes and unrelated up to first cousins belonging to Bhil indigenous population were recruited for the present study.

Laser-Induced Carbon-Based Smart Flexible Sensor Array for Multiflavors Detection.

We report a flexible sensor array electronic tongue system that is fabricated on a polymer substrate by the laser direct writing process for multiflavor detection. Electronic tongue is a sensing system that is applied to detect different elements with the same sensor array. By analyzing responses from different measurement units, it enables a cross-sensitivity, namely, the ability of the system to responding to a range of different analytes in solution without specific functionalization of sensors.

Improved ZnS nanoparticle properties through sequential NanoFermentation.

Sequential NanoFermentation (SNF) is a novel process which entails sparging microbially produced gas containing HS from a primary reactor through a concentrated metal-acetate solution contained in a secondary reactor, thereby precipitating metallic sulfide nanoparticles (e.g., ZnS, CuS, or SnS).

Vacuum-Assisted Low-Temperature Synthesis of Reduced Graphene Oxide Thin-Film Electrodes for High-Performance Transparent and Flexible All-Solid-State Supercapacitors.

Simple and easily integrated design of flexible and transparent electrode materials affixed to polymer-based substrates hold great promise to have a revolutionary impact on the functionality and performance of energy storage devices for many future consumer electronics. Among these applications are touch sensors, roll-up displays, photovoltaic cells, health monitors, wireless sensors, and wearable communication devices. Here, we report an environmentally friendly, simple, and versatile approach to produce optically transparent and mechanically flexible all-solid-state supercapacitor devices.

Manufacturing demonstration of microbially mediated zinc sulfide nanoparticles in pilot-plant scale reactors.

The thermophilic anaerobic metal-reducing bacterium Thermoanaerobacter sp. X513 efficiently produces zinc sulfide (ZnS) nanoparticles (NPs) in laboratory-scale (≤ 24-L) reactors. To determine whether this process can be up-scaled and adapted for pilot-plant production while maintaining NP yield and quality, a series of pilot-plant scale experiments were performed using 100-L and 900-L reactors.

Controllable Growth of Perovskite Films by Room-Temperature Air Exposure for Efficient Planar Heterojunction Photovoltaic Cells.

A two-step solution processing approach has been established to grow void-free perovskite films for low-cost high-performance planar heterojunction photovoltaic devices. A high-temperature thermal annealing treatment was applied to drive the diffusion of CH3NH3I precursor molecules into a compact PbI2 layer to form perovskite films. However, thermal annealing for extended periods led to degraded device performance owing to the defects generated by decomposition of perovskite into PbI2.

Correlating high power conversion efficiency of PTB7:PC71BM inverted organic solar cells with nanoscale structures.

Advances in material design and device engineering led to inverted organic solar cells (i-OSCs) with superior power conversion efficiencies (PCEs) compared to their "conventional" counterparts, in addition to the well-known better ambient stability. Here, we report an in-depth morphology study of the i-OSC active and cathode modifying layers, employing a model system with a well-established bulk-heterojunction, PTB7:PC71BM as the active layer and poly-[(9,9-bis(3'-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt-2,7-(9,9-dioctylfluorene)] (PFN) as the cathode surface modifying layer. We have also identified the role of a processing additive, 1,8-diiodooctane (DIO), used in the spin-casting of the active layer to increase PCE.

In situ capping for size control of monochalcogenide (ZnS, CdS and SnS) nanocrystals produced by anaerobic metal-reducing bacteria.

Metal monochalcogenide quantum dot nanocrystals of ZnS, CdS and SnS were prepared by anaerobic, metal-reducing bacteria using in situ capping by oleic acid or oleylamine. The capping agent preferentially adsorbs on the surface of the nanocrystal, suppressing the growth process in the early stages, thus leading to production of nanocrystals with a diameter of less than 5 nm.

Scalable production of microbially mediated zinc sulfide nanoparticles and application to functional thin films.

A series of semiconducting zinc sulfide (ZnS) nanoparticles were scalably, reproducibly, controllably and economically synthesized with anaerobic metal-reducing Thermoanaerobacter species. These bacteria reduced partially oxidized sulfur sources to sulfides that extracellularly and thermodynamically incorporated with zinc ions to produce sparingly soluble ZnS nanoparticles with ∼5nm crystallites at yields of ∼5gl(-1)month(-1). A predominant sphalerite formation was facilitated by rapid precipitation kinetics, a low cation/anion ratio and a higher zinc concentration compared to background to produce a naturally occurring hexagonal form at the low temperature, and/or water adsorption in aqueous conditions.

The effect of the postdisaster context on the assessment of individual mental health scores.

Many scholars question the immense variation in rates of mental health outcomes across disaster studies. This study explains this variation by putting forward 2 methodological problems that are inherent to the effect of a disaster context on mental health screening scores. The Hopkins Symptom Checklist-25 was administered in a flood-affected group (n = 318) and a nonaffected group (n = 304) in Uttar Pradesh, India.

The impact of recurrent disasters on mental health: a study on seasonal floods in northern India.

Introduction: Very little is known on the impact of recurrent disasters on mental health.
